One expert says Israel's involvement in world affairs is limited by its focus on survival, but the precedent of saving Jews comes first.
Should Israel expand its power? It is not an easy question to ask or an easy expectation to bear. Israel is a small country that has seen it as an imperative to punch above its weight and maintain a qualitiative strategic edge against its enemies. But as the country has prioritized self-preservation since its independence, the challenges are great and at times seemingly overwhelming.
While the rise of General Abdel Fattah al-Sisi in Egypt may have somewhat changed things, Israel could have been said to have rivals in Cairo, Ankara and Tehran all at the same time before Sisi took power. At this same moment in history, a resurgence of anti-Semitism has extended pressure on the Jewish Diaspora for whom Israel is conceptually a mainstay and security guarantor. With the emergence of Islamic State (ISIS) and Iran, Israel is in search of friends - but might it be too weak to make them?
There is precedent to teach Israelis how they might view their own international “power,” Professor Shmuel Sandler, researcher at the Begin-Sadat Center for Strategic Studies, told Arutz Sheva.
“Ben-Gurion spoke of Israel as an or lagoyim – a light unto the nations – in a very spiritual way,” says Sandler, “but we have never had a chance to project that because we have been fighting for survival.”
Regional Intervention
Sandler illustrates that Jews over time have shown themselves to be more advocates for international peace and order, a realm that is “usually the lot of imperial powers” and not “small nations.” Yet, it would seem that in an ideal situation, Jewish Israel would support international institutionalism.
He cites Michael Waltzer’s lecture Universalism and Jewish Values, the Biblical prophet Amos’ rebuke to the nations as well as prophecies by Yeshayahu (Isaiah) and Micah as illustrating support for an international system of order and law. This clearly presents issues for Israelis today, not because Israel is in violation of international law, but because of the widespread consensus among international law specialists in Israel and abroad that Israel could never get a fair hearing if it ever had to present itself to an international court like the International Criminal Court (ICC).
But the striving for international order still weighs heavily on any sense of interventionism that might exist for Israelis. Plenty of essays about Passover illustrate there is a stream of liberation theology in Judaism.
“Judaism is revolutionary only when the political order is based upon repression, not when it is based upon mutual obligation,” says Sandler in his essay Toward a Theory of World Jewish Politics.
The multi-dimensional conflict between Syria and Iraq has solicited calls from other observers for Israel to be more assertive in the region - at least covertly - in order to aid the weak against the aggressive (i.e., numerous minorities in the region versus forces like ISIS). But many observers who might hope Israel would pursue a more assertive policy consistently comeback to needing to resolve the Palestinian question.
In his book Regional Powers in the New Middle East, Robert Kappel states that "Israel is a lonely power. It needs a more assertive regional foreign policy." Is Israel capable of incorporating military intervention into its Middle Eastern strategy?
“Yossi Beilin talked about intervention after peace with the Palestinians, then he said we should go for humanistic delegations as intervention but not military intervention; that is, not without a professional volunteer army.”
Here, Sandler describes that the current mission of the Israeli Defense Forces does not envision foreign intervention as a form of defense, and hence would be hard to justify to ordinary Israelis.
“When you have a draft you cannot ask some Jewish mother to send her son to fight some dictator in Somalia or some other place.”
A Vanguard for Global Jewry
“Whether or not Israel should prioritize Jews outside of Israel, that’s a good question,” Sandler told Arutz Sheva. “I bring some examples of that dilemma as a conflict between Israeli interests and Jewish communal interests like South Africa.”
“In all those cases posing no actual existential threat to the State of Israel, the Jewish state took world Jewish interests into account,” says Sandler. “The very fact that the Jewish interest in Israel’s foreign policy was at least considered supports the thesis of a Jewish foreign policy on the normative level.”
Sandler points to pidyon shvuim – the redeeming of captives – as having a strong influence on Israel’s foreign relations.
Israel has spoken out on behalf of world Jewry consistently, whether those communities abroad welcome Israel’s intervention or not. French Jewish leaders were put off by Prime Minister Binyamin Netanyahu's assertive comments after the attack on the kosher Hyper Cacher market in January when he called on French Jews to make Aliyah and implicitly abandon France.
Alternatively, it could be looked at that Netanyahu leveraged his own popularity among French Jews to create public pressure on French leaders to be more aggressive toward anti-Semitism in order to avoid further embarrassment at the words of Netanyahu.
There are also numerous examples of Israel lobbying on behalf of Soviet Jewry and Algerian Jews, both displayed as situations where Israel had to balance its Jewish interests with its national interests.
Sandler points to one example where Israel not only intervened diplomatically, but was willing to spend treasure to free Jews trapped behind one country’s border.
“I’ve spoken with several diplomats influenced by Jewish-specific concerns. I know for a fact the Romanian Aliyah we paid money to the government - (the) Jewish foreign minister (communist) made a deal in the 1950s where Israel paid upwards of $100 a head.” |

Unfortunately, the voice actors are the very last to know anything about new projects.
There have been many rumors surrounding Grand Theft Auto 6, and fans have been hanging onto any information they can possibly find about the game. Now, the latest person to offer up some sort of insight for fans is none other than the voice actor for the eccentric sociopath named Trevor from Grand Theft Auto 5, Steven Ogg.
In a recent interview with Comicbook.com, the topic of GTA6 was brought up of course, and Ogg was asked if he knew anything about the development of the game or whether or not he would be involved. At much disappointment to fans, Ogg claimed that he has “no idea” about anything regarding a potential new GTA title, and as far as if he’d have anything to do with it, he said that the actors are typically the “very last to know anything” about the project.
“I’ve heard about that, and people keep asking me, but I have no idea. The actor is the last to know anything, honestly. Like in everything.”
Of course, Ogg was asked about his time working as Trevor, Ogg stated that he has very fond memories of his experience playing the character, explaining that the motion capture was the most fun and mostly what brought Trevor’s craziness to life. When asked if he thought that Trevor could possibly make a return in the next title in the series, Ogg explained that it is very unlikely, considering each new installment features a new story and a new set of characters.
“He’s a great character, I don’t think they really follow … Those series don’t really follow the characters, they’re separate, so … GTA 6 is what it is and I wish whoever, whatever it is, all the best.”
It’s not too much of a surprise that even a voice actor for one of the GTA titles doesn’t know much about the next project considering how secretive Rockstar is about its work. Although the idea is fun, and will more than likely happen within the next few years, fans shouldn’t get their hopes up too much for something soon considering Rockstar is still supporting GTA5 and GTA Online due to their continued success.
While a new installment Grand Theft Auto remains a mystery, fans have the very highly-anticipated Red Dead Redemption 2 to look forward to scheduled for Spring 2018, as long as it doesn’t get delayed again.
Would you like to see Trevor star in another GTA title? Let us know in our discussions and join us on Discord, on our Facebook page, or Twitter! |

Dynamin and Activity Regulate Synaptic Vesicle Recycling in Sympathetic Neurons*
Neurotransmission in central neuronal synapses is supported by the recycling of synaptic vesicles via endocytosis at different time scales during and after transmitter release. Here, we examine the kinetics and molecular determinants of different modes of synaptic vesicle recycling at a peripheral neuronal synapse formed between superior cervical ganglion neurons in culture, via acute disruption of endocytosis with Dynasore, an inhibitor of dynamin activation, or a dynamin peptide (P4) that perturbs linkage of dynamin to clathrin coats through amphiphysin. When paired action potentials are generated to produce excitatory postsynaptic potential responses, the second response was reduced after application of Dynasore but not P4. In addition, graded reduction in synaptic transmission during a train of action potentials was accelerated by Dynasore but enhanced by P4. After full depletion of releasable vesicles, P4 delayed the recovery of synaptic transmission while Dynasore limited recovery to 10%. In control neurons, synaptic transmission is stable for more than 1 h under low frequency presynaptic stimulation (0.2 Hz), but was reduced gradually by P4 and rapidly but incompletely blocked by Dynasore at a much lower stimulation frequency. These results suggest two essential modes of dynamin-mediated synaptic vesicle recycling, one activity-dependent and the other activity-independent. Our findings extend the current understanding of synaptic vesicle recycling to sympathetic nerve terminals and provide evidence for a physiological and molecular heterogeneity in endocytosis, a key cellular process for efficient replenishment of the vesicle pool, and thus for synaptic plasticity.
The cycling of synaptic vesicles (SVs) 3 through repetitive episodes of exocytosis and endocytosis is fundamental to synaptic transmission (1). The classic endocytic cycle consists of vesicle exocytosis from a readily releasable pool (RRP) (2) followed by retrieval via a clathrin-mediated endocytotic pathway (3) that passes through a reserve pool (RP) (4) en route to the RRP (5,6). The classic pathway, well studied at the frog neuromuscular junction (3), also functions in brain central synapses (7,8). In addition, other nontraditional modes of recycling such as "kiss-and-run" (9) and fast recycling, which bypasses the RP (10), have been described (11)(12)(13)(14). Endocytic pathways have also been categorized in terms of their kinetics, as fast or slow (1,15). Together, it seems likely that various forms of SV recycling pathways function under different conditions of synaptic activity and in a cell type-specific manner (15,16).
Although the precise mechanisms of synaptic reformation remain a matter of debate (3)(4)(5)(6)(7), the GTPase dynamin has a key role for this process (17)(18)(19). Dynamin oligomerization in endocytic pits mediates neck constriction and scission (20). As a component of the clathrin coat, amphiphysin interacts with dynamin and links clathrin-coats to dynamin (21). Dynamin binds to the Src homology 3 (SH3) domain of amphiphysin I via the PSRPNR sequence in the dynamin polyproline domain near its C terminus (22,23). A myristoylated peptide derived from this sequence called P4 (QVPSR-PNRAP) is able to competitively block dynamin binding to amphiphysin I and II in vitro (24) and inhibits SV endocytosis, thus resulting in the depression of transmitter release (25). Dynasore, a specific cell-permeable dynamin inhibitor (26), completely blocks SV endocytosis, suggesting an essential role for dynamin in all forms of compensatory SV endocytosis, including "kiss-and-run" events (27). However, in the calyx of Held, a dynamin-independent endocytosis was detected in the presence of Dynasore (28).
The mechanism of SV recycling in sympathetic neurons remains an open question. To investigate this issue, we studied the cholinergic synapse formed between rat SCG neurons in culture (29). In this model system, it is possible to introduce reagents directly into presynaptic terminals by microinjection, and their effect on acetylcholine release evoked by action potentials can be monitored by recording EPSPs from neighboring neurons (29,30). By perturbing dynamin function with either P4 peptide or Dynasore, we examine both activity-dependent and -independent modes of endocytosis, as well as dynamin-dependent and -independent pathways for refilling of the RRP in sympathetic neurons.
EXPERIMENTAL PROCEDURES
Cultured SCG neurons were prepared as described previously (29,30). For immunocytochemistry, SCG neurons in culture (8 weeks) were fixed and stained as described previously (30) with polyclonal anti-dynamin 1 and anti-amphiphysin II antibodies (Santa Cruz Biotechnology, Santa Cruz, CA) or monoclonal anti-synaptophysin antibody (Sigma-Aldrich) (supplemental Fig. S1). For electrophysiology, SCG neurons 6 -8 weeks in culture were studied. EPSP recording and injection of peptides were performed as described previously (29,30). To measure the replenishment of the RRP with readily releasable SVs, either a paired-pulse protocol or 5-30 Hz stimulation for 2 s was applied. For each neuron pair, three recordings were performed every 2 min for each interval of stimuli, and the EPSP peak amplitudes were averaged to account for variations in transmitter release following repetitive action potentials. For the depletion of synaptic vesicles, action potentials were applied at 5 Hz for 4 min, and replenishment of readily releasable SVs was monitored by tracking the recovery of baseline EPSP via recording every 1 s. The peak amplitudes of EPSP were averaged, and the resultant values were smoothed by an eight-point moving average algorithm. To measure the change in readily releasable SVs during prolonged repetitive activity, EPSPs were recorded at either 0.2 or 0.05 Hz. The peak amplitudes were averaged and plotted against recording time with t ϭ 0 corresponding to the presynaptic injection of P4 (QVPSR-PNRAP), a scrambled control peptide (QPPASNPRVR), or bath application of Dynasore. 1 mM peptide in the injection pipette was applied as this is the concentration producing a maximum reduction of EPSP amplitude, whereas 5 mM peptide showed no further reduction. 4 For Dynasore bath application, 100 l of 1 mM Dynasore dissolved in 5% DMSO was drop-applied to a 1.25-ml bath. A final concentration of 80 M (0.4% DMSO) Dynasore was used to achieve maximum inhibition of endocytosis, because this concentration completely blocked all forms of endocytosis in hippocampal neurons (28). As a control, 5% DMSO was drop-applied, producing a bath concentration of 0.4%. To reach the final concentration it takes a few minutes after bath superfusion was stopped (31). Before recording EPSPs at 20 min after the Dynasore application, cultured SCG neurons showed no spontaneous synaptic activity (32), suggesting that reduction of SVs in the RRP with the treatment is unlikely. Error bars shown in the text and figures represent mean Ϯ S.E. A two-tailed Student t test was applied as indicated.
Readily Releasable SVs after Evoked Transmitter Release-
To examine the readily releasable SVs after single action potential-evoked transmitter release, a paired-pulse protocol was applied under acute disruption of endocytosis by P4 or Dynasore ( Fig. 1). Synaptic responses induced by two consecutive action potentials showed a depression of the second response (paired-pulse depression) with inter-stimulus interval (ISI) of 20 -100 ms. In contrast, at longer ISIs (200 -2000 ms) the amplitudes of the second response were similar to the first (Fig. 1A). Paired-pulse responses were subsequently recorded 20 min after either P4 (Fig. 1A) or Dynasore application (Fig. 1B). The amplitude and the ratio of the EPSPs did not change with P4 (Fig. 1A). In contrast, with Dynasore the amplitude of the second EPSP decreased more than the first EPSP (with ISI ϭ 50 ms: 14.7 Ϯ 0.9 mV 1st and 11.2 Ϯ 0.7 mV 2nd before Dynasore and 8.8 Ϯ 0.5 mV 1st and 5.0 Ϯ 0.7 mV 2nd after Dynasore; with ISI ϭ 120 ms: 13.2 Ϯ 0.9 mV 1st and 14.7 Ϯ 0.9 mV 2nd before Dynasore and 9.3 Ϯ 0.5 mV 1st and 6.6 Ϯ 1.0 mV 2nd after Dynasore, mean Ϯ S.E., n ϭ 5; p Ͻ 0.05, paired Student t test) (Fig. 1B, panel b). Thus the paired-response ratio decreased with Dyna-FIGURE 1. Replenishment of readily releasable SVs after single evoked action potential.

These results suggest that dynamin dysfunction prevented replenishment of readily releasable SVs with an ISI of Ͻ120 ms, although the clathrin-mediated pathway might not function in replenishment of readily releasable SVs with an ISI of Ͻ2 s. The time for the dynamin-mediated replenishment after a single action potential is much shorter than previous reports for fast endocytosis in hippocampal synapses in imaging studies ( ϭ 0.4 -6 s) (15). Dynasore is a specific inhibitor for endocytosis (24,28) and unlikely to affect SV fusion. Although the mechanism of paired-pulse depression in central synapses is thought to be associated with a decrease in release probability (33), SVs are able to fully release from the RRP within tens of milliseconds in synapses of cultured SCG neurons when depression is removed (34). The results indicate that rapid replenishment of the RRP via dynamin-mediated SV recycling occurs after an evoked transmitter release.
Readily Releasable SVs during and after Repetitive Transmitter Release-To examine readily releasable SVs during and after repetitive action potential firing, 2-s trains of 5-30 Hz action potentials were elicited every 2 min in five synaptic couples. The EPSP amplitude decreased during the train (Fig. 2, A-D, upper graphs), and the rate of the decay was dependent on the frequency of action potential generation (Fig. 2I). The trainevoked decrease in EPSP amplitude returned to the initial value 2 min after cessation of each train. Normalized first EPSP amplitudes recorded at 10, 20, and 30 Hz to those at 5 Hz were around 1 (Fig. 2, A-D and L). At 2 min after a series of recording, P4 or Dynasore was applied. EPSP recordings with trains of action potentials were resumed at 20 min after reagent application. In the presence of P4 or Dynasore, the EPSP amplitude did not return to the initial value during a 22-min cessation of firing. Normalized first EPSP amplitudes recorded at 5 Hz were 0.45 Ϯ 0.06 for P4 and 0.2 Ϯ 0.03 for Dynasore (Fig. 2, A, C, J, and L). Dynasore decreased EPSP amplitude rapidly with each successive train of action potentials, especially Ն10 Hz (Fig. 2, E-H and K). P4 enhanced the EPSP amplitude decrease at 20 and 30 Hz (G-I). As a control, the scrambled P4 peptide and DMSO control showed no change in EPSP amplitude (Fig. 2, B and D). The inhibition of the recovery with Dynasore was stronger than that with P4 (Fig. 2J). These results suggest that activitydependent endocytosis could be activated by a 2-s train of action potentials at Ͼ10 Hz, in addition to dynamin-mediated endocytosis seen after a single action potential (Fig. 1B). It should be noted that, in addition to recycling from the plasma membrane, Dynasore will inhibit vesicle budding from sorting endosomes that supply de novo synaptic vesicles to the RRP (35). Interestingly, the train-evoked decrease in EPSP amplitude in the presence of Dynasore returned to the initial value 2 min after cessation of each train. Normalized first EPSP amplitudes recorded at 10, 20, and 30 Hz were ϳ0.2 (Fig. 2, C, J, and L), suggesting a possible dynamin-independent pathway for replenishment of readily releasable SVs through the transport route from the RP to the RRP during the 2-min cessation of each train. We note that an incomplete effect of Dynasore or an effect of dynamin 3 at this synapse cannot be excluded with these data. However, inhibition of available dynamin 1 and 2 and most if not all components of endocytosis would be consistent with prior work employing similar concentrations of Dynasore (27,28).
Replenishment of Readily Releasable SVs after Depletion of Releasable SVs-To test whether both dynamin-dependent and -independent pathways can replenish readily releasable SVs, SVs in the presynaptic terminals were depleted with 4-min trains of 5-Hz action potentials, and the recovery of EPSP amplitude was measured every 1 s. At the end of the train, the EPSP amplitude was within baseline noise levels (Fig. 3, A and B), and subsequently recovered at two distinct rates: fast and slow (see arrows in Fig. 3A, panel a). A control scrambled P4 peptide or DMSO did not show any reduction in the recovery rate (Fig. 3, A (panel b) and B (panel b)). In contrast, both P4 and Dynasore inhibited fast recovery (Fig. 3, A (panel a), B (panel a), and C). At 20 s after the train, the EPSP amplitude was significantly smaller than that before reagent applications (Fig. 3C, panel b). These results indicate that releasable SVs are depleted, while SVs in the RP may persist at the end of a 4-min train of action potentials. Furthermore, SVs in the RP may refill the RRP through the dynamin-dependent and clathrin-mediated pathway. In addition, readily releasable SVs may also be replenished through a dynamin-independent pathway in the presence of Dynasore. At 5 min after the train, the EPSP amplitude recovered to 41.4 Ϯ 4.5% with P4, but remained at 12.3 Ϯ 2.1% with Dynasore (Fig. 3C, panel b). The slow recovery could be described by a linear relationship (Fig. 3C, panel a). The slopes before and after P4 injection were 8.1 Ϯ 1.7%/min and 6.7 Ϯ 1.6%/min (p ϭ 0.63, unpaired t test), whereas the slope with Dynasore was 0 Ϯ 0.4%/min (Fig. 3C, panel a). These results demonstrate that the slow recovery rate was not significantly affected by P4 but blocked completely by Dynasore, suggesting the replenishment of readily releasable SVs through dynamindependent recycling (18) or de novo sorting via an endosomal pool (35). Together, the results suggest that the fast replenishment of the readily releasable SVs may involve SV transport from the RP via dynamin-mediated and non-dynamin-mediated pathway, whereas the slow replenishment of the readily releasable SVs may be achieved solely through dynamin-mediated endocytosis.
Readily Releasable SVs during Low Frequency Repetitive Transmitter Release-To examine the role of the dynamin-mediated pathway in replenishment of readily releasable SVs during low frequency repetitive transmitter release, changes in the amplitude of EPSPs evoked by presynaptic action potentials at 0.2 or 0.05 Hz were measured (Fig. 4). P4 gradually reduced the EPSP amplitude at 0.2 Hz (Fig. 4A, panels a and c), but not at 0.05 Hz (Fig. 4A, panels b and c). At 40 min after P4 injection, reduction of EPSP amplitude was Ϫ47.9 Ϯ 9.4% at 0.2 Hz (n ϭ 7), and Ϫ11.7 Ϯ 6.4% at 0.05 Hz (n ϭ 4). This value was similar to the control value with the scrambled P4 peptide (Ϫ8.9 Ϯ 4.9% at 0.2 Hz; n ϭ 6) (Fig. 4A, panel d) In contrast, Dynasore reduced the EPSP amplitude at 0.2 and 0.05 Hz (Fig. 4B). The reduction rate was more rapid than that of P4 with 0.2 Hz stimuli (Fig. 4, A (panel a) versus B (panel a)). The decay time constant of the EPSP amplitude in the presence of Dynasore was 4.8 Ϯ 0.12 min at 0.2 Hz, and 13.2 Ϯ 0.17 min at 0.05 Hz (p Ͻ 0.01, unpaired t test) (Fig. 4B, panel d), whereas it was 28 Ϯ 1.0 min at 0.2 Hz in the presence of P4. These results suggest that dynamin also mediates replenishment of readily releasable SVs during low frequency firing. Surprisingly, the EPSP amplitude was very small at 60 min after Dynasore application, but not completely blocked. The amplitudes were 6.8 Ϯ 1.6% (at 0.2 Hz) and 6.8 Ϯ 0.9% (at 0.05 Hz) of the initial value before Dynasore application, suggesting that non-dynamin-mediated processes may function in replenishing readily releasable SVs, although further experiments will be necessary to address this issue in future.
DISCUSSION
In this study, we demonstrate that sympathetic neurons maintain synaptic transmission via the recycling of SVs through dynamin-mediated pathways during and after action potential activity.

Refilling of the RRP via dynamin-mediated endocytic pathways was dependent on both rate and number of action potential firing (Figs. , in accord with activity-dependent recycling of synaptic vesicles observed at other synapses. In contrast, another mode of the RRP refilling through a dynamin-mediated endocytic pathway was activated independently of action potential firing rate and number (Figs. 1-4), consistent with an activityindependent pathway. The third pathway, not affected by dynamin dysfunction, was also activated at all rates or numbers of firing tested (Figs. 3 and 4) and was thus activity-independent; it is estimated that 10% of SVs in readily releasable SVs were replenished via this pathway to maintain efficient synaptic vesicle recycling with long lasting repetitive firing of the SCG neuron. Compared with neurons in the central nervous system, sympathetic nerve fibers show relatively low firing activity in the 0.5-to 7.5-Hz range in vivo (36). Thus, evidence for activity-dependent refilling of the RRP observed in this study may reflect physiological synaptic transmission in autonomic neurons in vivo.
The kinetics of endocytosis is variable at different presynaptic terminals (15,16). In hippocampal neurons, imaging studies have shown a wide range of time constants for endocytosis from a ϭ 0.1-6 s for fast components (13,15) and ϭ 4 -90 s for slow clathrin-mediated endocytosis (15). In Drosophila neuromuscular synapses, two pathways of vesicle recycling (37) and two or three SVs pools, the RRP and the RP (38) or "immedi-ately releasable pool" (39), were documented. During short period or low frequency presynaptic activity, SVs in the RRP, including the immediately releasable pool but not those in the RP, participate in transmitter release, whereas vesicles in the RP are required during intense neuronal activity (Ͼ10 Hz). A dynamin mutant, shibire, exhibits rapid synaptic fatigue within 0.02 s of repetitive stimulation, a phenotype that cannot be explained by vesicle depletion, suggesting that dynamin is required for rapid replenishment of the RRP with synaptic vesicles (40). In the present study, reduction of the second of two consecutive EPSPs with an ISI of 0.05 s by Dynasore (Fig. 1B) suggests that in sympathetic neurons dynamin is also required for rapid replenishment of readily releasable SVs, in addition to its role in slow clathrin-mediated endocytosis, which contributes to SVs recycling via the RP. Our data suggest approximate time constants for endocytosis in cultured sympathetic neurons. The dynamin-mediated pathway is able to mobilize SVs to the RRP in Ͻ0.05 s after an action potential (Fig. 1B), and the dynamin-and clathrin-mediated pathway is able to transport SVs to the RRP in under 20 s (Fig. 4A), if P4, as proposed, could perturb clathrin-coats formation. Measuring the time constant of readily releasable SV replenishment via the non-dynamin-mediated pathway is technically difficult because of the small synaptic responses after dynamin inhibition.
Using primary cortical cultures from dynamin 1 knockout mice, Ferguson et al. (18) recently demonstrated that neuron- application (B, panel a). After 1 min control recording, a 4-min stimulation at 5 Hz was applied to deplete synaptic vesicles. EPSP amplitudes were normalized to the mean EPSP amplitudes before the 4-min train. The values from five to seven experiments were averaged and smoothed with a moving average algorithm. Note that the EPSP amplitude was zero at the end of the train stimuli and showed partial recovery at two different rates after cessation of SV depletion: fast (small arrow) and slow (large arrow). P4 or Dynasore application was performed 10 min after the EPSP recording. As a control, a scrambled P4 peptide (A, panel b) or DMSO was applied (B, panel b).

specific dynamin 1 is required for rapid SV recycling during high frequency (Ͼ10 Hz) stimulation, but not after cessation of the stimulus train. Dynamin 3 appears to share a similar role to dynamin 1. In contrast, ubiquitously expressed Dynamin 2 may play a role in slow activity-independent constitutive replenishment of clathrin-coated vesicles. Here we report that presynaptic terminals of a sympathetic neuron have two dynamin-mediated SV replenishment pathways, which differ in activity dependence. The relationship of these two recycling modes to specific dynamin isoforms will require further investigation.
The differential effects of P4 peptide and Dynasore may be accounted for different steps in which they are likely to participate in the endocytic pathway. P4 disrupts the interaction of dynamin with amphiphysin (24), which may interfere with formation of the clathrin-coat (21) or fission complex. On the other hand, Dynasore may act at a downstream step involving dynamin activity and subsequently provide constitutive inactivation of dynamin across the endocytic cycle. It is also possible that, by targeting different parts of the dynamin endocytic complex, P4 peptides and Dynasore may act on different time scales and efficacies and thus account for their differential effects. Clearly the two reagents provide unique insight into distinct roles of dynamin in endocytosis with respect to synaptic vesicle pool recovery during different patterns of action potential stimulation.
We should caution that one cannot exclude incomplete inhibition of dynamin function by injected P4 peptides, which may be unable to fully target preassembled dynamin endocytic complexes due to steric hindrance and lower concentrations at nerve terminals. Because it was technically unfeasible to collect enough injected neurons for in vitro biochemical co-immunoprecipitation study, we are unable to provide experimental evidence to verify the assumption that injected P4 peptide could completely block the dynamin-amphiphysin interaction in our SCG neurons. Although the amphiphysin I/II knockout mice exhibit some defects in synaptic vesicle recycling (41), its essential role in clathrin-mediated endocytosis remains further investigation. It is possible that P4 might target not only to amphiphysin but also to other SH3 domain-containing proteins (24), thus playing a less specific role in blocking endocytosis than that by Dynasore. However, previous work in the SCG neuron system has indicated that injected peptides at even lower concentrations can disassemble other preformed synaptic protein complexes (42). Furthermore, P4 peptides have the efficacy to block clathrin-dependent endocytosis at intracellular concentrations (25) that are comparable to those used in the current study, although it was injected into different neuronal types and the effect was measured by different readouts.
Likewise, one must interpret the Dynasore inhibition data with caution. Dynasore is a fast-acting cell-permeable small molecule that inhibits the GTPase activity of dynamin 1, dynamin 2, and Drp1, the mitochondrial dynamin (43). Thus, it remains possible that in SCG neurons Dynasore may inhibit endocytosis dependent on dynamins 1 and 2 but not dynamin 3. Incomplete inhibition can also not be excluded without an independent measure of endocytosis inhibition. To address these issues, investigation of the role of dynamin isoforms in synaptic vesicle endocytic pathways in SCG neurons is under further study. However, it should be noted that robust inhibition of dynamin 1 and 2 and most if not all kinetic components of endocytosis is consistent with prior work employing similar concentrations of Dynasore (27,28).
The results in the present study suggest a dynamin-independent pathway for SV recycling in a sympathetic neuron synapse. Recent studies at other synapses support this conclusion. SV endocytosis at the large presynaptic terminal of the calyx of Held is partially independent of dynamin (29). Endocytosis activated during intense stimulation persists in the calyx synapse dialyzing with Dynasore and PQVPSRPNRAP (called pp11, one amino acid longer than P4) (29). In peripheral dorsal root ganglion neurons, a calcium-and dynamin-independent form of rapid endocytosis, which is controlled by protein kinase A-dependent phosphorylation, has been described (44). It will be of interest to further examine the molecular and physiological basis of vesicle fission via dynamin-independent endocytosis and its relationship to kiss-and-run and other proposed fast, non-classic modes of synaptic vesicle recycling.
The synaptic short-term depression observed during repetitive neuronal firing may be attributed to multiple mechanisms, including a decrease in vesicle fusion probability, inactivation of voltage-gated Ca 2ϩ channels (34), or use-dependent inhibition of the vesicle release machinery (33). In hippocampal or neocortical neurons, rapidly recycled SVs in the RRP are capable of rapid reuse (45) and slow the rate of synaptic depression (46). Our study shows that synaptic transmission in cultured SCG neurons also decreases rapidly in response to repetitive action potential firing (Fig. 2). The decrease was strongly accelerated in the presence of Dynasore, suggesting that a rapid reduction in the number of vesicles available for fast release may contribute to synaptic depression. These results may suggest that dynamin-mediated pathways are critical to maintain baseline levels of neurotransmission. Together, our results along with other results in the literature indicate that distinct endocytic pathways may be engaged under distinct patterns of synaptic activity history, short-and long-term neuromodulation and cell type. For example, the release probability of presynaptic terminals (11), Ca 2ϩ and protein kinase activity may regulate the relative engagement of endocytotic pathways as a function of firing history and modulation (5,13,16). In addition, dynamic engagement of multiple modes of recycling may be useful in homeostatic maintenance of a working amplitude and gain of synaptic transmission under different stimulation patterns. In summary, the present data characterize the fundamental modes of SV recycling and refilling of the RRP in SCG neurons during and after single or sustained firing of action potentials, supporting the involvement of activity-dependent and -independent pathways with distinct molecular requirements for synaptic vesicle endocytosis. |

OZONE MONITORING BY GOME-2 ON THE METOP SATELLITES
The first Global Ozone Monitoring Experiment (GOME) has been successfully operated on board of ERS–2 since its launch in April 1995. The objective to measure the global distribution of ozone and several other trace gases has been achieved. Based on this heritage the advanced GOME-2 has been selected as payload for the first three METOP satellites to cover the need of operational ozone monitoring for the next 15 years. GOME has shown its capability to monitor total column ozone, ozone profiles, nitrogen dioxide, sulphur dioxide, formaldehyde, and halogen oxides. Cloud parameters such cloud fraction within the field of view, cloud top height, and cloud optical thickness are measured as well. Aerosol properties like aerosol optical thickness have been retrieved successfully. Near real time data are being provided by KNMI, IFE Bremen and DLR for total column ozone and ozone profile by KNMI. GOME was limited to the restricted resources (data rate, mass, power) of the ERS-2 satellite. GOME-2 is using the larger satellite resources of METOP: • to increase the spatial resolution to 40 km * 40 km for the total column products, • to provide the measurement of both sand ppolarised components of the incoming radiation with a high spatial sampling (40 * 5 km), and • to enhance its on-board calibration and characterisation capabilities by adding a white light source. On-ground calibration and characterisation will be improved by allowing more calibration measurements under operational conditions. The ground processing of earth radiance and solar irradiance will use the knowledge of more than 4 years of operational processing. |

The Australian government has authorized dingo “baiting programs” which allow farmers, not just wildlife officials, to lay poisoned bait to kill them.
Why? Because they could not think of anything else, and they just cannot think of any other way to placate the angry ranchers who complain of their sheep which are getting killed.
Killing one species to save another doesn’t make sense, and with all of the technology, and progressive forward thinking out there today, this is the best the government can come up with. This poor approach is not only nonsensical, but it is also creating a huge problem for the balance of the ecosystem.
Removing large carnivores can result in simultaneous population outbreaks of herbivores and smaller predators. And these population outbreaks, in turn, can have deadly effects on smaller mammals.
Here’s how that works: The absence of dingos in forests allows big grass-eaters like kangaroos and wallabies to flourish, as well as red foxes. While the swelling ranks of foxes feast on small ground-dwelling mammals, decimating their numbers, the growing population of herbivores clears away ground cover, making it even harder for those animals to evade foxes. Which means more little dead mammals and an ecosystem to devastated to recover.
Poisoning of dingoes is counter-productive for biodiversity conservation, and we need to take a stand to bring this silly approach to a stop. Ranchers and government need to be engaged and a more proactive solution brought forward where both farmers and their livestock, can live in harmony with the indigenous wildlife; a solution that does not destroy an entire ecosystem.
Let’s send a clear message to the Australian government. We will not stand by while you use outdated and cruel methods to protect livestock. Make a change now before it is too late. |

Before Twitter announced plans to kill off Vine, the app's biggest stars reportedly banded together and pitched a plan they thought could save it.
Continue Reading Below
Mic reports that 18 of the app's top creators had a meeting with Vine's Creative Development Lead Karyn Spencer last fall, during which they demanded $1.2 million each to keep pumping out content for the platform.
The meeting was organized by Marcus Johns and Piques, who, along with other Vine stars, "had noticed a sharp dropoff in engagement on the app," Mic reports. In exchange for the huge payouts, they each promised to create 12 pieces of original content a month, or three vines each week.
"If Vine agreed, they could theoretically generate billions of views and boost engagement on a starving app," the report notes. "If they said no, all the top stars on the platform would walk."
The group — which reportedly included Jerry Purpdrank, Christian Delgrosso, Curtis Lepore, Alx James, and DeStorm Power — also urged Vine to make several product changes and open "a more direct line of communication" with creators. They wanted Vine to do a better job of tackling harassment on the platform, the ability to add links to Vine captions, a better recommendation page, and more editing tools, and they wanted these things right away.

"They never made changes, or when they did it was too late," Piques told Mic.
Vine rejected the proposal, and the stars stopped posting original content. And the rest, they say, is history.
Meanwhile, word has it that two of Vine's cofounders — Rus Yusupov and Colin Kroll — are already on to their next project: a Periscope-like app called Hype. According to Fortune, Hype is a "live video broadcasting app that lets users add music and animations to their videos." The app is currently in beta.

Giving birth to live young is one of the traits we use to distinguish mammals from other animals. But certain kinds of lizards, snakes and amphibians, both living and extinct, also reproduce without laying eggs. In fact, live birth (or viviparity) has evolved more than 100 separate times in non-mammal species throughout history. It seems to have been a common reproductive strategy in particular for extinct aquatic reptiles, such as the fish-like ichthyosaurs, plesiosaurs and mosasaurs that lived at the same time as the dinosaurs.
But one group of animals known as Archosauromorpha, which includes crocodiles, birds and their ancestors the dinosaurs, has never been known to give birth – until now. A recently unearthed fossil, described in a new study by a team of scientists from China, the US, UK and Australia, shows that an ancient species of archosauromorph was giving birth about 245 million years ago.
We’ll tell you what’s true. You can form your own view. From 15p €0.18 $0.18 $0.27 a day, more exclusives, analysis and extras.
The newly described specimen belongs to the species Dinocephalosaurus orientalis and was found in sediments from the early Triassic period in Yunnan Province, China. Dinocephalosaurus had a body length of around a metre but with an elongated neck of nearly twice that length. Its skull was relatively small and equipped with needle-like teeth adapted to catch fish and squids.
The shape of its skeleton suggests that it lived in water, but scientists originally thought it might have ventured onto land to lay eggs, as all known archosauromorphs do. The new fossil find now proves this theory to be wrong because it was found with an embryo preserved in its abdominal region. This provides compelling evidence for that this species of archosauromorphs gave birth to live young.
Compelling evidence
It is often hard to reconstruct a picture of an extinct creature and how it lived from a fossil, but a number of features strongly suggest that the new specimen does indeed represent a pregnant Dinocephalosaurus. The embryo’s skeleton has a very similar shape to the adult’s, showing that both belonged to the same species and that the embryo was in a very mature stage. The embryo is fully enclosed by the bones of the adult specimen and located in the pelvic region.
Remains of a partially digested fish were also found further up and between the ribs of the adult. This not only helps us identify the mother’s last meal, but also rules out the possibility that the embryo might have been devoured prey.

The embryo was also found in a curled-up position with the neck pointed towards the chest and forelimbs, which is a typical pose for vertebrate embryos. The withering of soft tissues such as muscles after an adult vertebrate dies means they are often fossilised in a typical death pose with the neck and tail arched back.
In this case, the mother animal was preserved in exactly this position but not the embryo. This makes it unlikely that both fossils died at different times and came to lie on top of each other by coincidence. Together, this provides good evidence that the new fossil is indeed that of a pregnant Dinocephalosaurus and its embryo.
Exceptionally preserved fossils, such as this one, allow a unique glimpse into the life of organisms over 245 million years ago, but they also have more far-reaching implications. Until now, it was assumed that all Archosauromorpha laid eggs. Modern members, represented by birds and crocodiles, are without exception oviparous (egg-laying), and fossilised eggs of dinosaurs and pterosaurs further supported this assumption.
Finding a pregnant Dinocephalosaurus demonstrates that at least some extinct archosauromorphs were giving birth to living young. It also means our knowledge of how archosauromorphs reproduced goes back 50 million years further than was previously possible. Until now, our oldest relevant fossils of this group were dinosaur eggs from the early Jurassic period (about 190 million years ago).
The results of this study also raise several questions. Viviparity has evolved independently and numerous times in all major types of vertebrate, with mammals probably the most prominent and successful example. Although giving birth is physically and energetically taxing for the parent, it has clear advantages for the offspring, which receives extra nutrients and protection, and develops without being affected by environmental conditions.
Yet archosauromorphs evolved away from this reproductive strategy to become the egg-laying dinosaurs, and eventually crocodiles and birds that we know. Why was this? We will now have to hope that future fossil finds might reveal another piece to the evolutionary puzzle.

Mission accomplished: a triumphant Ukip has achieved its goals and may as well pack up shop. The hard-right populist party is – in the words of its former leadership frontrunner Steven Woolfe – “in a death spiral”. Fresh from being literally hospitalised by the party’s internal divisions, Woolfe has marched out of this increasingly disorderly rabble. The party has been deprived of its toxic but effective figurehead, Nigel Farage, whose new pet project is spinning for Donald Trump; and with no clear unifying mission or leader, the party’s internal factions are abandoning any semblance of discipline. The party always represented a mishmash: some are rightwing libertarians, others anti-immigration national conservatives, others Tories-in-exile, others interested in forging a working-class rightwing populism. They are squabbling housemates wondering if they really belong under the same roof.
But hey, a flailing Ukip shouldn’t mourn. It helped engineer the EU referendum in concert with Tory backbenchers, and now its founding purpose has been achieved. But more importantly, the Conservative party has been Ukip-ised. Farage praised Theresa May’s “remarkable speech”, crowing that his party had “changed the centre of gravity of British politics. Virtually everything she said in that speech are things that I’ve said to the Ukip conference over the course of the last five or six years”. He is right to brag. A party that won only one parliamentary seat last year has effectively captured the commanding heights of the Tory party.
We now have a Conservative government pursuing a harsh and chaotic Brexit; demonising its critics as unpatriotic internal enemies; pursuing inflammatory anti-immigration ruses, such as floating the idea of drawing up lists of foreign workers; and pledging to expand selection in schools. If Ukip is dead, long live Ukip.
Ukip could still live on in some form, of course. It could be the option on the ballot paper for those who want to hold May’s feet to the fire: that’s why she’s been so keen to stress that Brexit means Brexit. Under the previous leadership, Labour made a miscalculation in believing that Ukip’s rise represented a fracturing of the right that would benefit them. In the end, it was Labour’s traditional coalition that fractured most lethally: in the direction of the SNP, Greens and Ukip.
Ukip’s turmoil certainly does underline the necessity for Labour to present a clear, coherent, inspiring vision. May’s alarmingly high poll rating is only partly explained by Labour’s decline: erstwhile Ukip voters flocking to the Tories is another reason. There are working-class Ukip voters who tell you they’d never vote Tory; May’s liberal use of “working class” is an attempt to address that. A significant chunk of working-class Britain feels alienated from Labour. That has to be addressed with a clear vision and a message communicated in language that resonates with people outside the political bubble. These are febrile times and Labour has an opportunity. If the party blows it, it won’t only be the Tories who are Ukip-ised – it will be a fate that befalls the whole country. |

Effects of Diet and Exercise on Peripheral Vascular Disease.
In brief A 46-year-old man presented with symptoms of peripheral vascular disease in 1966. In 1976 arteriography revealed 100% occlusion of both femoral arteries at midthigh and some reconstitution of flow via collaterals into the popliteal region. His cholesterol level was initially 407 mg/100 ml, and his walking tolerance was 100 yards. After a 26-day stay at the Pritikin Longevity Center, his cholesterol dropped from 230 mg/100 ml to 130 mg/100 ml, and his walking tolerance increased to 3 miles in one hour with little leg pain. He has run more than 20 road races and completed a marathon. A recent exercise Doppler exam and a second arteriogram indicated a significant increase in blood flow due to dilation of deep femoral arteries and existing collateral vessels. |

Declining prices of vegetable and other food articles pulled down wholesale inflation sharply to 3.74% in August to a nearly five-year low. The inflation measured on Wholesale Price Index (WPI) was at 5.19% in July and 6.99% in August 2013.
Inflation in the food segment witnessed a significant decline to 5.15% in August as against 8.43% in the previous month, according to official data released here today. The August WPI inflation is the lowest since October 2009 when it stood at 1.8%. Vegetable prices contracted 4.88%, the third continuous month of decline.
Maintaining a downward trend, the onion prices contracted by 44.7 % during the month under review. However, potato prices were on the rise as inflation in the kitchen essential jumped to 61.61% from 46.41% in July. Inflation in the fruits basket eased to 20.31% in August. While prices of protein rich items like egg, meat and fish contracted during the month, inflation in milk and pulses inched up to 12.18% and 7.81%, respectively, as compared to July. The August retail inflation too eased to 7.8% compared to 7.96% in July.
The wholesale WPI data further revealed that the price rise in manufactured goods, like sugar and edible oils too eased to 3.45% in August, while it was 3.67% in July. Inflation in the fuel and power segment which include LPG, petrol and diesel declined to 4.54% as compared to price rise of 7.40% seen in July. Meanwhile, wholesale inflation based on final index for June has been revised upwards to 5.66% from the provisional estimate of 5.43%. The August WPI data is also provisional, the government said. It also said the build up inflation rate in the financial year till August is 3% compared to a build up rate of 5.23% in the same period of 2013-14. |

Ten-Week-Old Girl With Lethargy, Weakness, and Poor Feeding
A 10-week-old previously healthy female infant presented to a community hospital after a brief episode of choking and “turning blue” while feeding. Parents reported a 4-day history of poor feeding, weakness, weak cry, and lethargy. The baby was primarily formula fed with some breast milk and taking about 4 ounces every 4 hours, until 4 days prior to admission when, because of her poor suck, parents began spoon-feeding her 1 to 2 ounces of formula every 4 hours. Review of systems was negative for fever, cough, and diarrhea but notable for 4 days without a bowel movement. Pregnancy was uncomplicated, and prenatal labs, including group B strep, were all negative and/or within normal limits, resulting in the birth of a 3.4 kg infant at 39 weeks’ gestation. Except for a recent diagnosis of oral candidiasis, the baby had no significant past medical history, exposures, sick contacts, or travel. She was being treated with oral nystatin for the candidiasis and had received her 2-month vaccinations. Vital signs on admission were normal for age; weight was 5.2 kg. On initial neurological exam, the patient showed global hypotonia and physiological deep tendon reflexes with hoarse cry and weak suck, but no signs of respiratory distress. Complete metabolic panel and creatinine kinase were within normal limits. C-reactive protein was slightly elevated at 8.95 mg/L (normal <5 mg/L). Urinalysis was unremarkable. White blood cell count was slightly elevated at 16.2 × 10/μL with 49% neutrophils and 42% lymphocytes. No lumbar puncture was performed; head ultrasound was normal. Blood and urine cultures were negative. She was admitted for dehydration and presumed clinical sepsis, treated with 7 days of ceftriaxone and discharged home with an adaptive nipple. However, because of persistent weakness and poor feeding, the primary care pediatrician admitted the patient to a different community teaching hospital 14 days after her symptoms began. Further questioning revealed that the constipation and weakening suck were initially accompanied by general lethargy and marked head lag, which progressed to include first upperand then lower-extremity weakness. Detailed exam included the presence of normoreactive pupils, facial diplegia, diminished/absent gag, muted cry, decreased/absent deep tendon reflexes, and intact anal wink with no tongue fasciculations or ptosis. This combination of progressive peripheral descending hypotonia, facial diplegia, bulbar involvement, and decreased deep tendon reflexes strongly suggested infant botulism. After consultation with the New York City Department of Health and Mental Hygiene (NYC DOHMH), stool samples were submitted to test for botulinum toxin by mouse bioassay and for Clostridium botulinum organism by polymerase chain reaction (PCR). Serum lactate, ammonia, serum carnitine, plasma quantitative amino acids, and urine organic acids were within normal limits. Noncontrast MRI of the brain and spine were normal. The infant was then transferred to our institution for a more extensive neurological evaluation on day 16 of illness. |

ASSOCIATION OF MATERNAL CHARACTERISTICS WITH COMPLICATIONS OF PREGNANCY: A CROSS-SECTIONAL STUDY AMONG MIDDLE SOCIOECONOMIC PREGNANT WOMEN
Objective: The objective of the study was to determine the association of maternal characteristics with complications of pregnancy among middle socioeconomic women.
Methods: The enrolled subjects were divided into two groups as complicated and uncomplicated group based on the occurrence of complications in current pregnancy and their sociodemographic details along with present and past medical and medication history was collected.
Results: The mean age of the study subjects was 25.33±4.22 years. Maternal characteristics such as age, parity, body mass index, maternal education, and employment status did not have a statistically significant association with the complications of pregnancy at p<0.05. However, the first antenatal visit at the gestational age <8 weeks had a statistically significant association with the complications of pregnancy at p=0.02.
Conclusion: Early initiation of antenatal care along with adequate antenatal visits may reduce the risk of complications of pregnancy. |

/**
* Created by Alex on 11/8/2017.
* Autonomous Objectives:
* --Knock Off Jewel for 30 Points
* --Score 1 Glyph (15 points) in Correct Column CryptoBox for (30 points)
* --Park in Safe Zone (10 points)
* Pseudocode:
* 0. Start on balancing stone, jewel mechanism faces the jewel
* 1. Knock off jewel (and read Pictograph, and lift Glyph 2 inches up)
* 2. Drive forward to drive off balancing stone
* 3. Drive backward to allign with balancing stone
* 4. Drive forward slowly to position needed to score in correct column
* 5. Rotate to -75 degrees to have glyph face CryptoBox
* 6. Drive forward toward CryptoBox until glyph is scored
* 7. Release the glyph
* 8. Rotate to -105 degrees to push glyph
* 9. Rotate to -45 degrees to push glyph
* 10. Rotate to -90 degrees to be perpendicular with wall
* 11. Drive backward a little bit to park
* End. Robot ends up aligned to score glyph in specific column of CryptoBox

When Dr. Jemma Green was completing her PhD she found that apartments in Australia didn't have easy access to renewable energy.
She decided to try and solve this problem by opening up the energy market, so people in apartment buildings could trade energy between themselves, without the need for a third-party energy company. To do this, Green developed a battery system which was the first of its kind in Australia. It would help people trade peer-to-peer, but she still needed software that would be able to sustain the process.
Her answer was blockchain technology and it was with this idea that Power Ledger was born.
Power Ledger is a peer-to-peer, blockchain-based energy trading platform, where renewable energy can be sold between buyers and sellers without a middleman.
So, let's take a step back and work through what blockchain technology actually is and how it allows Power Ledger to work towards making the energy market more accessible.
Getty Images/iStockphoto How does blockchain have the power make the energy market more democratic?
What Is Blockchain, Anyway?
Blockchain is an emerging technology that changes the way we trade and transact with each other. One major change that comes with blockchain is the way that it digitises transactions of both currencies and commodities. Another important factor that defines blockchain is the way it establishes peer-to-peer trading. This means that digital currencies or commodities, like energy, can be transferred from one person to another without relying on a middleman like a bank or power company to process the transaction for you.
Blockchain is in its early stages of development and will soon become something we use without really knowing. In terms of development, it's like we are back in 1994, when the internet or email was developing -- we don't really understand the full capabilities of blockchain yet, but eventually we will use it as easily as we use the internet now.
Sometimes it can be confusing to separate Bitcoin and blockchain but, it's important to remember that Bitcoin is simply the most mature example of a digital currency that uses blockchain technology. Bitcoin and blockchain are not the same thing -- Bitcoin just uses blockchain to move from person to person.
The blockchain is able to manage and organise a lot more than just money and the work Power Ledger is doing is a perfect example of how blockchain can be used to make transactions with commodities more transparent.
What Is Power Ledger And What Do They Do?
So, back to Power Ledger.
Power Ledger uses blockchain technology to allow buyers and sellers to trade solar energy between each other without needing to rely on a third-party company. Dr Jemma Green, Co-Founder and Chair of Power Ledger told HuffPost Australia that Power Ledger formed with two key concepts in mind -- peer-to-peer trading across energy networks and peer-to-peer trading of energy within buildings.
The focus of these two key areas aims to start solving structural problems in the energy market where people are moving off the grid.
"We set up the company in May of last year after seeing some problems in the market. So Dave [Co-Founder Dave Martin] who has been working in energy networks for two decades ... saw that the energy networks business has a structural problem and that because of distributed renewables the network is being used less," Green said.
"So people left using it are paying more and [he] saw that the blockchain could encourage more trading across the network."
So how are they approaching this widespread problem?
"We are moving from a centralised system to a distributed energy system," Green explained. "So, I think that in terms of the peer-to-peer trading product it can be about maintaining the utilisation of the grid and making the idea of going off the grid less attractive because the grid is a very valuable asset.
"Not everyone can afford to buy solar panels and they might not have the roof space for it or they are renting and I think our platform gives renters access to renewables."
Green also said that Power Ledger's distributed platform means that landlords would have an incentive to invest in renewable energy for their tenants.
"Landlords are like 'why would I put solar panels on the roof for the tenant if they get the benefit?', where as, if the landlord gets the income in the form of an electricity bill that would justify them investing in that in the first place."
How Is Energy Digitised To Sit On The Blockchain?
Power Ledger uses a software solution that measures the amount of electricity consumed or generated. The way the energy is moved from one person to another is via a unit called 'Sparkz' which is a tokenised unit of electricity or a digital representation of the energy that is being moved from the buyer to the seller.
"Basically, Power Ledger has a software solution and it connects to smart metres. It reads the outputs of the metres in terms of electricity that is being consumed or generated and it records that on the blockchain," Green told HuffPost Australia.
"As somebody purchases or consumes electricity that is also recorded on the blockchain and those two pieces of information from the transaction for which Sparkz are transferred -- so it happens synchronously. The actual recording of the electricity is the movement of Sparkz from the buyer's wallet to the seller's wallet."
This means that the buyer is receiving the payment for the electricity at almost the same time the seller receives the payment for the energy. This happens in the form of Sparkz being transferred between the two parties via the blockchain. Once the seller receives the Sparkz into their digital wallet, they can convert those to Australian dollars.
"So normally what happens is, you do a transaction and the payment happens afterwards and in electricity markets ... every 60 days you might get a bill and then in the wholesale market it could be 60-80 days, so this means that you get paid for the value that you provide instantly."
How Can We Get Involved And Why Should We Care?
Power Ledger has had massive success in both Australian and international markets. Even Elon Musk has approached Power Ledger for information about what they are doing in the energy space. Their success is fast proving that digital energy and the vast applications of blockchain technology is something we should be interested in.
Currently people can buy POWR Tokens in their sale, which closes Friday October 6 at 6pm AEDT. In their presale, over $AUD17 million was raised and so far in their current sale they have raised $USD10.9 million.
This sale is Australia's first ever Initial Coin Offering -- or ICO -- and Power Ledger is calling it the Token Generation Event. An ICO is a sale where a blockchain company like Power Ledger sells parts of their ledger to people and this gives them access to the function of the blockchain. This could be gaining an income stream, owning a portion of an asset or gaining a licence to some kind of data.
To participate in the ICO you need to go the Power Ledger website. To purchase a POWR token you need to use a cryptocurrency -- either Bitcoin, Ether or Litecoin.
Green says that digital energy and a peer-to-peer network is worth investing in, because it promotes a green and more accessible energy solution.
"I would say that Power Ledger's mission is around democratising power and we think ... that is going to become even more pronounced and this is about people getting a return for the contribution that they make to the energy system," Green said.
"And they get a proper return for those contributions and I think that the potential with the Power Ledger platform is to create a really fair and transparent energy system, that is low cost and low carbon." |

Amazon's first e-reader, the Kindle, was so popular that it sold out in a matter of hours (Jon 'ShakataGaNai' Davis / Wikimedia Commons).
The legacy of color e-paper may be muted and dim, but its past, at least, is black-and-white: monochrome E Ink set the tone for a decade of reflective, low-power displays.
Naturally, it didn't take long for consumers to want more -- sure, a sunlight-readable display that lasted for days on a single charge was great, but what about color? This, too, was in the works for a few years, but progress was slow. Early prototypes from Fujitsu did a decent job of mirroring their monochrome cousins' modest power consumption, but images often appeared washed out and faded, like a newspaper left in the sun too long. The technology failed to beat the next Kindle to market, but improved as the years went on. In the meantime, Barnes & Noble added a splash of color to the e-reader market by attaching a secondary, peripheral LCD display to its Nook e-reader -- providing a vibrant and active navigation hub under its reading surface.
The race to create a consumer-ready color e-paper display heated up as Barnes & Noble, Sony and Amazon fought over market share -- if electronic reading devices were to be the next big thing, then surely color would be the category's killer feature. Companies like Samsung, Bridgestone, E Ink (then known as PVI), Fujitsu, Qualcomm, Philips and Plastic Logic spent the better parts of 2009 and 2010 teasing us with brighter screens, faster refresh rates and flexible-display technology.
The original nook had a 6-inch e-paper display, with a color touchscreen at the bottom (Andrew Magill (Amagill) / Wikimedia Commons).
Despite the excitement surrounding color e-paper, however, few firms were actually ready to put their cards on the table. In early 2010, Amazon CEO Jeff Bezos dispelled rumors of an incoming Kindle Color, saying that current prototypes were simply "not ready for prime-time production," based on what he'd seen in the company's labs. Sony also dodged the subject, committing itself to its existing line of monochrome e-readers until higher-quality panels were available. Even the companies behind the technology openly admitted that it wasn't ready -- PVI and Qualcomm both delayed their respective E Ink Triton and Mirasol color displays, independently describing them as unsatisfactory. Worse still was the high cost of color e-paper development, which drove Samsung to back out of the industry in 2010.
Unfortunately, the delays didn't stave off consumer demand for a color reading device, and it came to market through the path of least resistance: the LCD. This veteran technology may not have been able to compete with color e-paper in the arenas of power consumption or visibility in direct sunlight, but it made up for these faults with bright, accurate color reproduction and the ability to play back video content. More importantly, the technology was available, and the growing tablet market soon offered a ready alternative to the developing color e-paper technology. Companies betting on color e-paper were soon forced to re-evaluate their strategies, Qualcomm told Engadget back at SID 2011, citing Apple's inaugural tablet as the catalyst for its partners' reconsideration.
The Koobe Jin Yong e-reader with Qualcomm's Mirasol display technology (Qualcomm).
The original iPad didn't kill the color e-reader independently, of course -- the device was simply too large and too expensive to scratch the itch for every digital-reading enthusiast with an eye for color. Barnes & Noble's first full-color e-reader didn't have these problems. Launched in late 2010 for $250, the 7-inch Nook Color was the right device at the right time, introducing an affordable color reading device while simultaneously giving the bookseller an edge in the growing e-reader market. It didn't take long for Amazon to react to the positive consumer response, launching its own LCD color e-reader, the Kindle Fire, for a scant $200 the following year. The color e-paper offerings of the same era just couldn't compete -- Kyobo's $310 Mirasol eReader was panned for having poor battery life and unstable software, and an E Ink Triton device by Hanvon priced itself out of the market with a staggering $530 sticker. What's worse, consumers didn't even seem to know these products existed. The damage was done; the category's biggest brands knew they could create a successful color e-reader without next-generation e-paper. By the time ASUS and Google trumped the Kindle Fire with the Nexus 7, the technology was all but forgotten.
The damage was done; the category's biggest brands knew they could create a successful color e-reader without next-generation e-paper.
Color e-paper may have faded from the public consciousness after media tablets usurped its role in the consumer electronics space, but the technology itself lives on, albeit dimly. PVI, a company so dedicated to reflective-display technology that it changed its name to E Ink Holdings Incorporated, refocused its efforts on new markets, creating programmable supermarket price tags and digital billboards for European firms. It's even limping along in the color e-reader space, although we wouldn't call it a major player -- the most recent device to sport the company's Triton color E Ink display, the Jetbook, sells for an astounding $500. Hardly priced to sell, but the company tells us that it has seen some success in European classrooms. Despite these efforts, the company isn't exactly shining: in its Q2 2013 financial report, E Ink posted a $33.6 million loss -- its biggest in four years. Citing numbers from IHS, the report optimistically looked to Western European purchasing trends to cushion the blow, but more telling are the losses suffered in North America, which is now exhibiting a 15 percent loss in worldwide e-reader shipments when compared to 2011. The devices just aren't selling as fast as they used to.
Other companies are sending mixed messages. Qualcomm's Mirasol technology shipped in precious few devices before the company put a lid on production last summer, yet it continues to demonstrate new and intriguing prototypes. At SID 2013, for instance, the company trotted out a smartphone with a reflective 5.1-inch, 2,560 x 1,440 display and a 1.5-inch smartwatch, teasing a future of color e-paper-equipped hardware. The company was quick to point out that the devices were mere mock-ups, but a similar watch surfaced at the company's Uplinq developer conference earlier this week, taking the name of Toq. The smartphone display is still missing in action, however, and Qualcomm says it'll need a few more years in R&D before it's ready for market. When we asked the company if it was still developing screens for color digital readers, Qualcomm representatives could only tell us that they had nothing new to announce. Clearly the company's Mirasol technology is still moving forward, but the firm seems focused on smaller devices.
Amazon's recent Liquavista acquisition raises even more questions: if the iPad, Kindle Fire and Nook Color sealed the fate of color e-paper years ago, why did one of the industry's biggest e-reader manufacturers purchase a company known for low-power color displays? Reaching out directly for an answer proved futile for Engadget -- the company won't budge on the future of color e-paper or Amazon's intentions for the next-generation Kindle device.
Ectaco's pricey jetBook Color 2 with a Triton 2 color e ink screen (Ectaco).
Hushed acquisitions and quiet color-display advancements aren't enough to save color e-paper, however. More daunting than the display category's technological hurdles are the commercial roadblocks in its path: consumers are simply losing interest in the e-reader category as a whole. That certainly isn't to say that it's a dead or dying market, but it's slowly trending toward the niche. According to an IDC forecast released in March, e-reader shipments fell by a staggering 31 percent in a single year -- peaking at 26.4 million in 2011 and dropping to 18.2 million in 2012. At the same time, tablet sales have increased by about 11 percent, with about half of all devices sold falling into an e-reader-competitive form factor, measuring eight inches or smaller. Worse still, these numbers are for traditional monochrome e-readers, not the hopeful color models that failed to take flight.
The Kindle brand and its sunlight-readable e-paper display probably aren't going anywhere, but the category is edging away from the mainstream. Users demand more out of their devices these days, and slow-refreshing E Ink just can't cut it for a media tablet. If our predictions for the future need to be grounded in reality, then maybe it's time we finally put our color e-reader dreams to bed. The technology may eventually find a home somewhere, but at this rate, it likely won't be on our nightstand. |

We assumed that we were dealing with a true sensitization perhaps combined with some irritant effect, facilitating the onset of sensitization and its continuance. Over the past few years, several authors have reported pathological cutaneous signs due to acrylic resins. The most frequent reactions found by French authors (Ducome et al. 1974, Beurey et al. 1977) seem to be of an irritant type. But Beurey placed emphasis on the fact that four mechanics appointed to maintain the machines presented with a genuine eczema later. In Sweden, Magnusson & Mobacken (1972) and Wahlberg (1974) have published cases of allergic contact dermatitis to acrylic resins. It seems that the main difficulty lies in knowing whether an interplay of irritation and sensitization occurs commonly, or whether true sensitization is the unusual pathological effect of acrylic resins. |
