This back here was my brain cancer.
Isn't it nice?
(Laughter) The key phrase is "was," phew.
(Applause) Having brain cancer was really, as you can imagine, shocking news for me.
I knew nothing about cancer.
In Western cultures, when you have cancer, it's as if you disappear in a way.
Your life as a complex human being is replaced by medical data: Your images, your exams, your lab values, a list of medicines.
And everyone changes as well.
You suddenly become a disease on legs.
Doctors start speaking a language which you don't understand.
They start pointing their fingers at your body and your images.
People start changing as well because they start dealing with the disease, instead of with the human being.
They say, "What did the doctor say?"
before even saying, "Hello."
And in the meanwhile, you're left with questions to which nobody gives an answer.
These are the "Can I?" questions: Can I work while I have cancer?
Can I study?
Can I make love?
Can I be creative?
And you wonder, "What have I done to deserve this?"
You wonder, "Can I change something about my lifestyle?"
You wonder, "Can I do something?
Are there any other options?"
And, obviously, doctors are the good guys in all these scenarios, because they are very professional and dedicated to curing you.
But they also are very used to having to deal with patients, so I'd say that they sometimes lose the idea that this is torture for you and that you become, literally, a patient -- "patient" means "the one who waits."
(Laughter) Things are changing, but classically, they tend to not engage you in any way to learn about your condition, to get your friends and family engaged, or showing you ways in which you can change your lifestyle to minimize the risks of what you're going through.
But instead, you're forced there to wait in the hands of a series of very professional strangers.
While I was in the hospital, I asked for a printed-out picture of my cancer and I spoke with it.
It was really hard to obtain, because it's not common practice to ask for a picture of your own cancer.
I talked to it and I said, "Okay, cancer, you're not all there is to me.
There's more to me.
A cure, whichever it is, will have to deal with the whole of me."
And so, the next day, I left the hospital against medical advice.
I was determined to change my relationship with the cancer and I was determined to learn more about my cancer before doing anything as drastic as a surgery.
I'm an artist, I use several forms of open-source technologies and open information in my practice.
So my best bet was to get it all out there, get the information out there, and use it so that it could be accessed by anyone.
So I created a website, which is called La Cura, on which I put my medical data, online.
I actually had to hack it and that's a thing which we can talk about in another speech.
(Laughter) I chose this word, La Cura -- La Cura in Italian means "the cure" -- because in many different cultures, the word "cure" can mean many different things.
In our Western cultures, it means eradicating or reversing a disease, but in different cultures, for example, a culture from Asia, from the Mediterranean, from Latin countries, from Africa, it can mean many more things.
Of course, I was interested in the opinions of doctors and healthcare providers, but I was also interested in the cure of the artist, of the poet, of the designer, of, who knows, the musicians.
I was interested in the social cure, I was interested in the psychological cure, I was interested in the spiritual cure, I was interested in the emotional cure, I was interested in any form of cure.
And, it worked.
The La Cura website went viral.
I received lots of media attention from Italy and from abroad and I quickly received more than 500,000 contacts -- emails, social networking -- most of them were a suggestion on how to cure my cancer, but more of them were about how to cure myself as a full individual.
For example, many thousands of videos, images, pictures, art performances were produced for La Cura.
For example, here we see Francesca Fini in her performance.
Or, as artist Patrick Lichty has done: He produced a 3D sculpture of my tumor and put it on sale on Thingiverse.
Now you can have my cancer, too!
(Laughter) Which is a nice thing, if you think about it, we can share our cancer.
And this was going on -- scientists, the traditional medicine experts, several researchers, doctors -- all connected with me to give advice.
With all this information and support, I was able to form a team of several neurosurgeons, traditional doctors, oncologists, and several hundred volunteers with whom I was able to discuss the information I was receiving, which is very important.
And together, we were able to form a strategy for my own cure in many languages, according to many cultures.
And the current strategy spans the whole world and thousands of years of human history, which is quite remarkable for me.
[Surgery] The follow-up MRIs showed, luckily, little to no growth of the cancer.
So I was able to take my time and choose.
I chose the doctor I wanted to work with, I chose the hospital I wanted to stay in, and in the meanwhile, I was supported by thousands of people, none of whom felt pity for me.
Everyone felt like they could take an active role in helping me to get well, and this was the most important part of La Cura.
What are the outcomes?
I'm fine, as you can see, pretty fine.
(Applause) I had excellent news after the surgery -- I have -- I had a very low-grade glioma, which is a "good" kind of cancer which doesn't grow a lot.
I have completely changed my life and my lifestyle.
Everything I did was thoughtfully designed to get me engaged.
Up until the very last few minutes of the surgery, which was very intense, a matrix of electrodes was implanted in my brain from this side, to be able to build a functional map of what the brain controls.
And right before the operation, we were able to discuss the functional map of my brain with the doctor, to understand which risks I was running into and if there were any I wanted to avoid.
Obviously, there were.
[Open] And this openness was really the fundamental part of La Cura.
Thousands of people shared their stories, their experiences.
Doctors got to talk with people they don't usually consult when they think about cancer.
I'm a self-founding, continuous state of translation among many different languages, in which science meets emotion and conventional research meets traditional research.
[Society] The most important thing of La Cura was to feel like a part of a really engaged and connected society whose wellness really depends on the wellness of all of its components.
This global performance is my open-source cure for cancer.
And from what I feel, it's a cure for me, but for us all.
Thank you.
(Applause).
When we think of Nepal, we tend to think of the snow-capped mountains of the Himalayas, the crystal-clear still waters of its alpine lakes, or the huge expanse of its grasslands.
What some of us may not realize is that in the Himalayan foothills, where the climate is much warmer and the landscape much greener, there lives a great diversity of wildlife, including the one-horned rhinoceros, the Asian elephant and the Bengal tiger.
But unfortunately, these animals are under constant threat from poachers who hunt and kill them for their body parts.
To stop the killing of these animals, battalions of soldiers and rangers are sent to protect Nepal's national parks, but that is not an easy task, because these soldiers have to patrol thousands of hectares of forests on foot or elephant backs.
It is also risky for these soldiers when they get into gunfights with poachers, and therefore Nepal is always looking for new ways to help with protecting the forests and wildlife.
Well recently, Nepal acquired a new tool in the fight against wildlife crime, and these are drones, or more specifically, conservation drones.
For about a year now, my colleagues and I have been building drones for Nepal and training the park protection personnel on the use of these drones.
Not only does a drone give you a bird's-eye view of the landscape, but it also allows you to capture detailed, high-resolution images of objects on the ground.
This, for example, is a pair of rhinoceros taking a cooling bath on a hot summer day in the lowlands of Nepal.
Now we believe that drones have tremendous potential, not only for combating wildlife crime, but also for monitoring the health of these wildlife populations.
So what is a drone?
Well, the kind of drone I'm talking about is simply a model aircraft fitted with an autopilot system, and this autopilot unit contains a tiny computer, a GPS, a compass, a barometric altimeter and a few other sensors.
Now a drone like this is meant to carry a useful payload, such as a video camera or a photographic camera.
It also requires a software that allows the user to program a mission, to tell the drone where to go.
Now people I talk to are often surprised when they hear that these are the only four components that make a conservation drone, but they are even more surprised when I tell them how affordable these components are.
The facts is, a conservation drone doesn't cost very much more than a good laptop computer or a decent pair of binoculars.
So now that you've built your own conservation drone, you probably want to go fly it, but how does one fly a drone?
Well, actually, you don't, because the drone flies itself.
All you have to do is to program a mission to tell the drone where to fly.
But you simply do that by clicking on a few way points on the Google Maps interface using the open-source software.
Those missions could be as simple as just a few way points, or they could be slightly longer and more complicated, to fly along a river system.
Sometimes, we fly the drone in a lawnmower-type pattern and take pictures of that area, and those pictures can be processed to produce a map of that forest.
Other researchers might want to fly the drone along the boundaries of a forest to watch out for poachers or people who might be trying to enter the forest illegally.
Now whatever your mission is, once you've programmed it, you simply upload it to the autopilot system, bring your drone to the field, and launch it simply by tossing it in the air.
And often we'll go about this mission taking pictures or videos along the way, and usually at that point, we will go grab ourselves a cup of coffee, sit back, and relax for the next few minutes, although some of us sit back and panic for the next few minutes worrying that the drone will not return.
Usually it does, and when it does, it even lands automatically.
So what can we do with a conservation drone?
Well, when we built our first prototype drone, our main objective was to fly it over a remote rainforest in North Sumatra, Indonesia, to look for the nest of a species of great ape known as the orangutan.
The reason we wanted to do that was because we needed to know how many individuals of this species are still left in that forest.
Now the traditional method of surveying for orangutans is to walk the forest on foot carrying heavy equipment and to use a pair of binoculars to look up in the treetops where you might find an orangutan or its nest.
Now as you can imagine, that is a very time-consuming, labor-intensive, and costly process, so we were hoping that drones could significantly reduce the cost of surveying for orangutan populations in Indonesia and elsewhere in Southeast Asia.
So we were very excited when we captured our first pair of orangutan nests on camera.
And this is it; this is the first ever picture of orangutan nests taken with a drone.
Since then we have taken pictures of dozens of these nests from around various parts of Southeast Asia, and we're now working with computer scientists to develop algorithms that can automatically count the number of nests from the thousands of photos we've collected so far.
But nests are not the only objects these drones can detect.
This is a wild orangutan happily feeding on top of a palm tree, seemingly oblivious to our drone that was flying overhead, not once but several times.
We've also taken pictures of other animals including forest buffalos in Gabon, elephants, and even turtle nests.
But besides taking pictures of just the animals themselves, we also take pictures of the habitats these animals live in, because we want to keep track of the health of these habitats.
Sometimes, we zoom out a little and look at other things that might be happening in the landscape.
This is an oil palm plantation in Sumatra.
Now oil palm is a major driver of deforestation in that part of the world, so we wanted to use this new drone technology to keep track of the spread of these plantations in Southeast Asia.
But drones could also be used to keep track of illegal logging activities.
This is a recently logged forest, again in Sumatra.
You could even still see the processed wooden planks left on the ground.
But perhaps the most exciting part about taking pictures from the air is we could later stitch these pictures together using special software to create a map of the entire landscape, and this map gives us crucial information for monitoring land use change, to let us know where and when plantations might be expanding, where forests might be contracting, or where fires might be breaking out.
Aerial images could also be processed to produce three-dimensional computer models of forests.
Now these models are not just visually appealing, but they are also geometrically accurate, which means researchers can now measure the distance between trees, calculate surface area, the volume of vegetation, and so on, all of which are important information for monitoring the health of these forests.
Recently, we've also begun experimenting with thermal imaging cameras.
Now these cameras can detect heat-emitting objects from the ground, and therefore they are very useful for detecting poachers or their kayla30@example.org.
So I've told you quite a lot about what conservation drones are, how you might operate one of these drones, and what a drone could do for you.
I will now tell you where conservation drones are being used around the world.
We built our first prototype drones in Switzerland.
We brought a few of these to Indonesia for the first few test flights.
Since then, we've been building drones for our collaborators from around the world, and these include fellow biologists and partners from major conservation organizations.
Perhaps the best and most rewarding part about working with these collaborators is the feedback they give us on how to improve our drones.
Building drones for us is a constant work in progress.
We are constantly trying to improve them in terms of their range, their ruggedness, and the amount of payload they can carry.
We also work with collaborators to discover new ways of using these drones.
For example, camera traps are a common tool used by biologists to take pictures of shy animals hiding in the forests, but these are motion-activated cameras, so they snap a picture every time an animal crosses their path.
But the problem with camera traps is that the researcher has to go back to the forest every so often to retrieve those images, and that takes a lot of time, especially if there are dozens or hundreds of these cameras placed in the forest.
Now a drone could be designed to perform the task much more efficiently.
This drone, carrying a special sensor, could be flown over the forest and remotely download these images from wi-fi–enabled cameras.
Radio collars are another tool that's commonly used by biologists.
Now these collars are put onto animals.
They transmit a radio signal which allows the researcher to track the movements of these animals across the landscape.
But the traditional way of tracking animals is pretty ridiculous, because it requires the researcher to be walking on the ground carrying a huge and cumbersome radio antenna, not unlike those old TV antennae we used to have on our rooftops.
Some of us still do.
A drone could be used to do the same job much more efficiently.
Why not equip a drone with a scanning radio receiver, fly that over the forest canopy in a certain pattern which would allow the user or the operator to triangulate the location of these radio-collared animals remotely without having to step foot in the forest.
A third and perhaps most exciting way of using these drones is to fly them to a really remote, never-explored-before rainforest somewhere hidden in the tropics, and parachute down a tiny spy microphone that would allow us to eavesdrop on the calls of mammals, birds, amphibians, the Yeti, the Sasquatch, Bigfoot, whatever.
That would give us biologists a pretty good idea of what animals might be living in those forests.
And finally, I would like to show you the latest version of our conservation drone.
The MAJA drone has a wingspan of about two meters.
It weighs only about two kilograms, but it can carry half its weight.
It is a fully autonomous system.
During its mission, it can even transmit a live video feed back to a ground station laptop, which allows the user to see what the drone is seeing in real time.
It carries a variety of sensors, and the photo quality of some of these sensors can be as high as one to two centimeters per pixel.
This drone can stay in the air for 40 to 60 minutes, which gives it a range of up to 50 kilometers.
That is quite sufficient for most of our conservation applications.
Now, conservation drones began as a crazy idea from two biologists who are just deeply passionate about this technology.
And we believe, strongly believe, that drones can and will be a game changer for conservation research and applications.
We've had our fair share of skeptics and critics who thought that we were just fooling around with toy planes.
And in a way, they are right.
I mean, let's be honest, drones are the ultimate toys for boys.
But at the same time, we've also gotten to know many wonderful colleagues and collaborators who share our vision and see the potential of conservation drones.
To us, it is obvious that conservation biologists and practitioners should make full use of every available tool, including drones, in our fight to save the last remaining forests and wildlife of this planet.
Thank you.
(Applause)
