Nearly a year after being being christened by the masses, Boaty McBoatface prepares to make her first journey into the icy waters of Antarctica. The brightly-colored and remote-controlled mini-sub, an autonomous underwater vehicle, gained its name in March 2016 via an online poll conducted by the UK’s Natural Environment Research Council.
The poll was originally intended to pick the name of the NERC’s new massive polar research vessel, which clocks in at 129 meters long and can carry up to 90 researchers and support staff. Fitted out with equipment like two helipads and a prow that can break through a meter of ice, the new vessel will lead the charge to explore polar marine biology and climate science. When the Internet got wind of the poll, one cheeky reader’s suggestion of “RRS Boaty McBoatface” shot to the top of the rankings, eventually picking up over 120,000 votes—well above any other competitors.
Despite winning the online poll hands-down, the NERC opted to go with a more traditional name for their new ship, choosing runner-up entry “RRS David Attenborough” as the winning submission. While it definitely seems more appropriate to name the ship after the famed British broadcaster and naturalist, the NERC didn’t let the Internet down completely. They announced that as a tip of the hat to all the fans who chimed in with their opinion online, the Attenborough’s three companion remote underwater vehicles would all bear the name Boaty McBoatface.
While Boaty’s parent ship won’t be ready for deployment until sometime in 2019, Boaty herself is ready to go right now. After making the rounds on some BBC talk shows, the AUV linked up with another UK research ship. British Atlantic Survey vessel the James Clark Ross will set sail from Chile on March 17th, heading towards Antarctica—where the mini-sub will be used to explore the 2-mile-deep Orkney Passage. Fair winds and following seas, Boaty, you’ve got millions of fans rooting for you!
11-Year-Old Scientist Creates Lead Detector for Water.
Genius can show itself in many ways, some people have propositions, others create. It’s all a game of “Who can implement these solutions to a full extent?”. This 11-year-old girl decided to take the matters into her own hands and revolutionized the world of science and health. By creating a lead detector device, this girl contributed to end the massive contamination of the liquids in her region once and for all.
The story begins at Flint, Michigan. An 11-year-old girl named Gitanjali Rao took notice of the water crisis people were having at the time. The drinking water became contaminated with led and caused a major public health crisis.
“I had been following the Flint, Michigan, issue for about two years,” Gitanjali told ABC News. “I was appalled by the number of people affected by lead contamination in water and I wanted to do something to change this.”
When she saw the current solutions that were painfully average and slow at best. The girl decided to step up and fight this, but how? Lead isn’t that easy to detect in contaminated water, right? Well, like any inventor, she made her best effort to make this an easy process for everyone.
She told Business Insider that: “I went, ‘Well, this is not a reliable process and I’ve got to do something to change this,’ ” And so, she went on a quest to find the best solution to the problem.
First, she went to the MIT’s Materials Science and Engineering website to see “if there’s anything’s new,” she read about new technologies that could detect hazardous substances and decided to see whether they could be adapted to test for lead.
Once she found out a project that worked best, she created a device that fulfills one basic purpose: Identify lead compounds in water, portable and relatively inexpensive. And she succeeded.
The device consists of 3 essential parts: There is a disposable cartridge containing chemically treated carbon nanotube arrays, an Arduino-based signal processor with a Bluetooth attachment, and a smartphone app that can display the results. The name? Tethys, like the Greek Goddess of Fresh Water.
How does it work? The carbon nanotubes in the cartridge are sensitive to changes in the flow of electrons. Those tubes are lined with atoms that have an affinity to lead, which adds a measurable resistance to the electron flow.
Once the cartridge is dipped in water that is clean, the electron flow doesn’t change and the smartphone app shows that water is safe to drink. However, if it is contaminated water, the lead in the water reacts to the atoms, causing resistance in the electron flow that is measured by the Arduino processor. The app then shows that the water isn’t safe to drink.
This invention is such a work of art and creativity; it deserves the greatest amount of recognition. And as such, Rao was dubbed “America’s Top Young Scientist” in the Discovery Education 3M Young Scientist Challenge this distinction comes with a check for $25,000, more than enough compensation for saving many.
Here at GeekReply, we hope that this child genius aspires to the greatest of futures. With the recent contributions that have been helping science and health developments. People like this could be a great help for the brighter future of human society.
General Motors to Release 20 Electric Cars by 2023
There have been a lot of new pushes to take the electric cars to the next level. A lot of countries have been approving laws that will decrease the use of fuel cars for the sake of a better future. It seems like General Motors is going to add more to the plans of a greener environment where cars are usually hybrid or electric.
In a push to produce cars powered by batteries or fuel cells, General Motors laid out a strategy to vastly expand the number of electric models in the marketplace. G.M. said it would introduce two new all-electric models within 18 months as part of a broader plan toward what the company says is the ultimate goal of an emissions-free fleet. The two models will be the first of at least 20 new all-electric vehicles that G.M. plans to bring out by 2023.
G.M.’s chief executive, Mary T. Barra, announced in September that the company, America’s largest automaker, expected the industry to move aggressively toward an automotive future with zero emissions, traffic accidents and highway congestion.
“General Motors believes in an all-electric future,” Mark Reuss said at a media event at the company’s technical center in the Detroit suburb of Warren. “Although that future won’t happen overnight, G.M. is committed to driving increased usage and acceptance of electric vehicles.”
He declined to specify what type of new models will be built off the Bolt’s underpinnings, but the chief of G.M.’s electrification strategy, Pam Fletcher, said the company is focusing on the development of sport utility vehicles and car-based crossover models.
There still isn’t a set timeframe for an all-electric portfolio of products, and the company expects to continue making cars and trucks powered by gasoline engines for an indefinite period of time. But at the very least they want to make some progress like many other companies have.
California Might Ban the Sale of Non-Electric Cars
Gas-powered cars might soon be a thing of the past in California, at least if Governor Jerry Brown and chairman of the California Air Resources Board Mary Nichols have any say on the matter.
According to Bloomberg, Nichols claimed Brown is interested in banning the sale of cars (and other vehicles) that use an internal-combustion engine within the state of California. This ban is not just a response to similar proposed bans in foreign countries, including China and France; it is also designed to help California meet climate goals set by Global Automakers, which hope to reduce carbon dioxide emissions by 80% from 1990 levels. According to Nichols, the best way to reach this goal is to “pretty much replace all combustion with some form of renewable energy by 2040 or 2050.” Replacing internal-combustion engines with electric engines just might do the trick.
While the ban won’t take effect for at least a decade, Nichols believes it might run into several legal problems. While California can create pollution laws thanks to the Clean Air Act, these laws need to be supported by waivers from the Environmental Protection Agency (EPA). However, the EPA has been under attack from the Trump administration, which, according to Nichols, means California likely won’t receive an EPA waiver to enforce the ban. However, Nichols has suggested several alternatives, such as controlling of vehicle registration rules and deciding which vehicles can or can’t access state highways.
Another possible wrench in Brown and Nichols’ ban plan is if it’s feasible. Global Automakers has purportedly claimed that China’s internal-combustion engine car ban would be impossible, although, to be fair, China’s plan is much more ambitious. Instead of replacing all internal-combustion cars by 2050, China hopes to replace one-fifth of their cars by 2025, create quotas in 2018 to facilitate the replacements, and to enforce severe penalties on those who doesn’t comply. At first glance, this plan doesn’t look more ambitious, but reports indicate the number of people who own cars in China eclipses the population of California. Depending on how California plans to enforce the ban, Global Automakers might oppose it.
Nichols believes a ban on selling non-electric cars could happen as early as 2030, but we will have to wait much longer to see if the ban effectively cuts down on carbon dioxide emissions. Or if California car-owners accept the ban.

Karibu mwaka mmoja baada ya kubatizwa na watu wengi, Boaty McBoatface anajitayarisha kufanya safari yake ya kwanza katika maji ya barafu ya Antaktika. Mini-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub-sub- Uchunguzi huo ulikusudiwa awali kuchagua jina la meli mpya ya utafiti wa NERC, ambayo ina urefu wa mita 129 na inaweza kubeba watafiti 90 na wafanyakazi wa msaada. Meli hiyo mpya, ambayo ina vifaa kama vile helipad mbili na kiunzi kinachoweza kuvunja barafu kwa mita moja, itasababisha uchunguzi wa biolojia ya baharini na sayansi ya hali ya hewa. Wakati mtandao ulipopata upepo wa uchaguzi, pendekezo la msomaji mmoja wa ujasiri wa "RRS Boaty McBoatface" lilipiga risasi juu ya orodha, hatimaye kukusanya zaidi ya kura 120,000 - juu sana ya washindani wengine wowote. Licha ya kushinda kura ya mtandaoni, NERC ilichagua kwenda na jina la jadi zaidi kwa meli yao mpya, ikichagua kuingia kwa runner-up <unk>RRS David Attenborough<unk> kama kuwasilisha kushinda. Ingawa ni dhahiri inaonekana sahihi zaidi kwa jina meli baada ya maarufu Uingereza mtangazaji na naturalist, NERC hakuwa basi Internet chini kabisa. "Wakati huo huo, kwa heshima ya mashabiki wote walioshirikiana na maoni yao mtandaoni, magari matatu ya chini ya maji ya Attenborough yatakuwa na jina la ""Boaty McBoatface.""" Wakati meli ya mama ya Boaty haitaweza kuhamishwa hadi wakati fulani katika 2019, Boaty mwenyewe yuko tayari kwenda sasa hivi. Baada ya kufanya mzunguko kwenye baadhi ya vipindi vya mazungumzo vya BBC, AUV ilihusianishwa na meli nyingine ya utafiti ya Uingereza. Meli ya uchunguzi wa bahari ya Atlantiki ya Uingereza, James Clark Ross, itasafiri kutoka Chile tarehe 17 Machi, kuelekea Antaktika, ambapo mini-submarine itatumiwa kuchunguza njia ya Orkney yenye kina cha maili mbili. Upepo mzuri na bahari inayofuata, Boaty, una mamilioni ya mashabiki wakukuunga mkono! Mwanasayansi wa miaka 11 atengeneza kifaa cha kugundua risasi Uwezo wa kipaji waweza kujionyesha kwa njia nyingi, watu fulani wana mapendekezo, wengine huunda. Ni wote mchezo wa <unk> Nani anaweza kutekeleza ufumbuzi huu kwa kiasi kamili? <unk>. Msichana huyo mwenye umri wa miaka 11 aliamua kuchukua mambo mikononi mwake na kuleta mabadiliko makubwa katika sayansi na afya. Kwa kuunda kifaa cha kugundua risasi, msichana huyu alichangia kukomesha uchafuzi mkubwa wa kioevu katika eneo lake mara moja na kwa wote. Hadithi hiyo huanza huko Flint, Michigan. Msichana wa miaka 11 Gitanjali Rao, ambaye ni mmoja wa waathirika wa janga la maji nchini India, aliwahi kuuawa. Maji ya kunywa yalichafuliwa na risasi na kusababisha mgogoro mkubwa wa afya ya umma. "Nilikuwa nikifuatilia suala la Flint, Michigan, kwa miaka miwili", Gitanjali aliliambia ABC News. "Nilishtuka na idadi ya watu walioathiriwa na uchafuzi wa risasi katika maji na nilitaka kufanya kitu kubadilisha hili. "" Alipoona suluhisho la sasa ambalo lilikuwa la wastani sana na polepole zaidi." Msichana huyo aliamua kujihusisha na jambo hilo, lakini kwa njia gani? Si rahisi kugundua risasi katika maji yaliyochafuliwa, sivyo? Kama mvumbuzi yeyote, alifanya kila awezalo kufanya kazi hiyo iwe rahisi kwa kila mtu. "Alisema: ""Nilikuwa na wazo kwamba hii sio mchakato wa kuaminika na lazima nifanye kitu kubadilisha hili, na hivyo, alienda kutafuta suluhisho bora kwa tatizo hilo." "Kwanza, alienda kwenye tovuti ya MIT ya Sayansi ya Vifaa na Uhandisi ili kuona ""kama kuna kitu chochote kipya,"" alisoma juu ya teknolojia mpya ambazo zinaweza kugundua vitu hatari na aliamua kuona ikiwa zinaweza kubadilishwa kwa kupima risasi." Baada ya kugundua mradi uliofanya kazi vizuri zaidi, aliunda kifaa ambacho kinatimiza kusudi moja la msingi: kutambua misombo ya risasi katika maji, inayoweza kubebwa na isiyo na gharama kubwa. Na alifanikiwa. Kifaa hicho kina sehemu tatu muhimu: cartridge ya kutumiwa moja kwa moja iliyo na safu za nanotube za kaboni zilizotengenezwa kwa kemikali, processor ya ishara ya Arduino na kiunganishi cha Bluetooth, na programu ya simu ya mkononi inayoweza kuonyesha matokeo. Jina lake? Tethys ni mungu wa maji safi wa Ugiriki. Inafanya kazije? Vipuli vya nanotube vya kaboni vilivyo katika cartridge huathiriwa na mabadiliko katika mtiririko wa elektroni. Vipande hivyo vimefunikwa na atomu zenye uhusiano wa karibu na risasi, na hivyo kuongeza upinzani unaoweza kupimwa kwa mtiririko wa elektroni. Mara tu cartridge imezamishwa katika maji safi, mtiririko wa elektroni haubadiliki na programu ya simu ya mkononi inaonyesha kwamba maji ni salama kunywa. Hata hivyo, ikiwa ni maji ya uchafuzi, risasi katika maji huitikia atomu, na kusababisha upinzani katika mtiririko wa elektroni ambayo hupimwa na processor ya Arduino. Kisha programu hiyo inaonyesha kwamba maji hayo si salama kunywa. Uvumbuzi huu ni kazi ya sanaa na ubunifu; inastahili utambuzi mkubwa zaidi. "Rao alipewa jina la ""Mwanasayansi wa Vijana wa Juu wa Amerika"" katika changamoto ya Discovery Education 3M Young Scientist, tofauti hii inakuja na hundi ya $ 25,000, zaidi ya fidia ya kutosha kwa kuokoa wengi." Hapa katika GeekReply, tunatumaini kwamba mtoto huyu wa kipaji anatamani siku zijazo bora zaidi. Kwa sababu ya michango ya hivi karibuni ambayo imekuwa ikisaidia maendeleo ya sayansi na afya. Watu kama hawa wanaweza kuwa msaada mkubwa kwa ajili ya siku zijazo zenye kung'aa za jamii ya kibinadamu. General Motors itatoa magari 20 ya umeme ifikapo 2023 - Gari la umeme la umeme la umeme Nchi nyingi zimepitisha sheria za kupunguza matumizi ya magari ya mafuta kwa ajili ya siku zijazo bora. "Mfano wa kampuni ya General Motors, ambayo inaendelea kuendeleza ""muziki wa kijani kibichi"" katika magari yake, ni magari ya umeme au ya umeme." Katika juhudi za kuzalisha magari yanayoendeshwa na betri au seli za mafuta, General Motors iliweka mkakati wa kupanua idadi ya mifano ya umeme sokoni. G.M. Kampuni hiyo imesema itaanzisha mifano miwili mpya ya umeme ndani ya miezi 18 kama sehemu ya mpango mkubwa wa kufikia lengo la mwisho la meli zisizo na uzalishaji wa gesi. GMC imesema kuwa ni ya kwanza kati ya magari 20 ya umeme ambayo kampuni hiyo itatengeneza. Mipango ya kuanzisha na kuanzisha kwa 2023 Mkurugenzi Mtendaji wa GM, Mary T. Barra, alitangaza mnamo Septemba kwamba kampuni hiyo, mtengenezaji mkubwa wa magari nchini Marekani, inatarajia sekta hiyo kusonga kwa nguvu kuelekea siku zijazo za magari na uzalishaji wa sifuri, ajali za barabarani na msongamano wa barabara. "General Motors inaamini katika siku zijazo za umeme kabisa", Mark Reuss alisema katika tukio la vyombo vya habari katika kituo cha kiufundi cha kampuni hiyo katika kitongoji cha Detroit cha Warren. <unk> Ingawa wakati ujao huo hautafanyika usiku mmoja, G.M. "Bolt imeahidi kuongeza matumizi ya magari ya umeme, lakini haijatoa maelezo kuhusu aina ya gari hilo, lakini mkuu wa mkakati wa umeme wa GM, Pam Fletcher, alisema kampuni hiyo inazingatia maendeleo ya magari ya michezo na magari ya magari ya ""crossover.""" Bado hakuna muda uliowekwa kwa ajili ya bidhaa za umeme, na kampuni inatarajia kuendelea kutengeneza magari na malori yanayoendeshwa na injini za petroli kwa muda usiojulikana. Lakini angalau wanataka kufanya maendeleo kama makampuni mengine mengi yamefanya. California: Gari la umeme linaweza kuwa jambo la zamani katika California, angalau kama Gavana Jerry Brown na Mwenyekiti wa Bodi ya Rasilimali za Hewa ya California Mary Nichols wana maoni yoyote juu ya suala hilo. Kulingana na Bloomberg, Nichols alidai Brown anapendezwa na marufuku ya kuuza magari (na magari mengine) ambayo hutumia injini ya mwako wa ndani ndani ya jimbo la California. "Hii sio tu majibu kwa marufuku zinazopendekezwa kama hizo katika nchi za kigeni, ikiwa ni pamoja na China na Ufaransa; pia imekusudiwa kusaidia California kufikia malengo ya hali ya hewa yaliyowekwa na Global Automakers, ambayo wanatarajia kupunguza uzalishaji wa kaboni dioksidi kwa 80% kutoka viwango vya 1990.""" "Nichols anasema njia bora ya kufikia lengo hilo ni ""kuchukua nafasi ya moto wote na aina fulani ya nishati mbadala ifikapo 2040 au 2050"" na ""kuchukua nafasi ya injini za mwako wa ndani na injini za umeme inaweza kufanya kazi.""" Wakati marufuku haitakuwa na athari kwa angalau muongo mmoja, Nichols anaamini inaweza kukimbia katika matatizo kadhaa ya kisheria. California inaweza kuunda sheria za uchafuzi wa hewa kwa sababu ya Sheria ya Hewa Safi, lakini sheria hizi zinahitaji kuungwa mkono na msamaha kutoka kwa Shirika la Ulinzi wa Mazingira (EPA). Hata hivyo, EPA imekuwa chini ya mashambulizi kutoka kwa utawala wa Trump, ambayo, kulingana na Nichols, inamaanisha California pengine haitapokea msamaha wa EPA kutekeleza marufuku. Hata hivyo, Nichols amependekeza njia mbadala kadhaa, kama vile kudhibiti sheria za usajili wa magari na kuamua ni magari gani yanayoweza au hayawezi kufikia barabara kuu za serikali. Muhimu mwingine unaowezekana katika mpango wa marufuku wa Brown na Nichols ni ikiwa inawezekana. Kampuni ya Global Automakers imedai kuwa marufuku ya magari ya ndani ya China itakuwa haiwezekani, ingawa, kwa uadilifu, mpango wa China ni wa kutamani zaidi. Badala ya kuondoa magari yote ya mwako wa ndani ifikapo mwaka 2050, China inatarajia kuondoa asilimia tano ya magari yao ifikapo mwaka 2025, kuanzisha viwango vya kuondoa magari hayo mwaka 2018 na kutekeleza adhabu kali kwa wale ambao hawataki kufanya hivyo. Kwa mtazamo wa kwanza, mpango huu haionekani kuwa na tamaa zaidi, lakini ripoti zinaonyesha idadi ya watu ambao wana magari nchini China inazidi idadi ya watu wa California. Ikitegemea jinsi California inavyopanga kutekeleza marufuku hiyo, Global Automakers inaweza kupinga. Nichols anaamini kwamba marufuku ya kuuza magari yasiyo ya umeme inaweza kutokea mapema kama 2030, lakini itabidi tungojee kwa muda mrefu zaidi kuona kama marufuku hiyo inapunguza uzalishaji wa kaboni dioksidi. Au ikiwa wamiliki wa magari wa California wanakubali marufuku hiyo. Kwa nini Nexus 7 bado ni kibao kizuri katika 2015 - Samsung Galaxy Note 4 vs Galaxy Note 5: Je, kuna nafasi ya kuboresha?
