The Poppy project aims at building an Open-source humanoid platform based on robust, flexible, easy-to-usehardware and software. Designed by the Flowers Lab at Inria Bordeaux and Ensta ParisTech (France), its development aims at providing an affordable and hackable humanoid robot for science, education, art and geeks.
Designer Fabienne Felder teamed up with Cambridge scientists to explore solar cells that use moss to generate electricity.
"Designer Fabienne Felder wants to reupholster jumbo jets with moss. In her vision, passengers will sit on verdant tufts while the bryophytes purify the air and use electrons captured during photosynthesis to power the Direct TV panels on the seat backs. Many would think Felder was crazy, but biochemist Dr. Paolo Bombelli and plant scientist Ross Dennis from the University of Cambridge were impressed with her brio and offered her the opportunity to collaborate (...)"
Organic semiconductors allow for flexible displays, solar cells, and other applications. One common problem in these devices, however, is the interface between the metallic contacts and the organic semiconductor material, where undesirable losses occur. Now researchers have shown what these losses depend upon.
Pour affronter les flux de données de l’Internet des Objets, les ordinateurs de demain devront être beaucoup plus puissants mais aussi beaucoup moins consommateurs d’énergie et bien plus denses. L’internet des objets et le Big Data vont multiplier par 5
"À l’heure où les connexions en fibre et la 4G sont sur toutes les lèvres dans l’hexagone, les utilisateurs assoiffés de vitesse s’échangent des données en centaines de mégabits, voire en gigabits par seconde. C'est oublier que dans certaines régions du monde, une connexion internet n’a rien de systématique. En 2013, il restait encore 61 % de la population mondiale à connecter à Internet. Mais il existe surtout une réelle fracture numérique entre les pays du Nord et ceux du Sud. Par exemple, seuls 16 % de la population africaine dispose d’un accès à Internet, contre 75 % des Européens (...)"
Whether you’re a science teacher or not, education and the STEM subjects is a hot topic these days. From discussions about comparing test scores in STEM subjects with students around the globe to tracking the number of STEM based jobs and future graduates, there’s certainly a lot to discuss. There’s a lot of information out …
I really hate WiFi, and you should too. If you own your own home or your landlord doesn't mind a few holes in the wall, running gigabit Ethernet around the house is the best thing you can do for a faster computing experience. But what's all this about Cat 6 or crossover cables? Here's everything…
"GPS can be useful when you're trying to navigate to that hot new bar -- as long as your travels don't take you somewhere its signal can't reach. A new so-called quantum positioning system could pick things up when satellites fail, and help guide your way using super-cooled atoms. Aside from better directions, the solution might even make travel safer..."
"Une équipe de scientifiques vient de créer un nouvel outil GPS capable de retracer l'histoire de votre ADN jusqu'à sa région d'origine. Vous n'avez besoin que d'un kit ADN avant de rentrer vos résultats sur le site. Un modèle information déterminera ensuite où votre ADN s'est formé, il y a 1.000 ans..."
"The Illustris project is a large cosmological simulation of galaxy formation, completed in late 2013, using a state of the art numerical code and a comprehensive physical model. Building on several years of effort by members of the collaboration, the Illustris simulation represents an unprecedented combination of high resolution, total volume, and physical fidelity. The About page contains detailed descriptions of the project, for both the general public and researchers in the field..."
Cette nouvelle simulation numérique reproduit l’évolution de la matière et la formation des galaxies durant plus de 13 milliards d’années au sein d’un cube de 350 millions d’années-lumière de côté.
You don't need an expensive Nest to connect your home to the Internet of Things.
"The connected home, the ultimate ideal in technology-driven luxury, promises easy living by passing along our drudgery to computers. But it’s not perfect.
Even if you’re willing to shell out for expensive devices for your house, are you willing to trust them? There’s always the concern that when a middleman is involved, you’re relinquishing at least some control of your own domain.
In that case, why not roll your own connected home? ..."
"Running your own Web server is the ultimate mark of online independence—and it only need cost you $35.
Never underestimate the miniscule, $35 Raspberry Pi. Although it’s marketed as an experimental machine aimed at helping you learn to code, there’s nothing entry-level about its capabilities.
In a pinch, you can even use your Raspberry Pi as a Web server. You can host a simple site or store files in the cloud so you can access them at any time—no monthly hosting fees, limited templates, or other barriers to your creativity (...)"
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified light bulbs. This is why early computers like the ENIAC weighed more than 27 tons and consumed more power than a small town. Later, obviously, vacuum tubes would be replaced by probably the greatest invention of all time -- the solid-state transistor -- which would allow for the creation of smaller, faster, cheaper, and more reliable computers. Fast forward to 2014, though, and the humble CMOS field-effect transistor (FET) is starting to show its age. We've pretty much hit the limit on shrinking silicon transistors any further, and they can't operate at speeds much faster than a few gigahertz. Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.
The Next Big Thing for mobile phones will help out carriers and smartphone makers quite a bit. Consumers? Not so much.
If you haven't already, soon you're going to be hearing a lot about a new standard for making mobile phone calls: VoLTE. It stands for "voice over LTE," but what it really means is that before long, your voice calls are going to be transmitted across the airwaves using the same technology the Internet pioneered for data (...)
Researchers are using the geometry of paper folding to come up with futuristic antennas that can retract and compress.
When talking about the intersection of art and science, Stavros Georgakopoulos likes to quote Albert Einstein, who once said, "I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge."...
"The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. It is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the earth which are enclosed in a pressurized and temperature controlled housing. Video from these cameras is transmitted back to earth and also streamed live on this channel. While the experiment is operational, views will typically sequence though the different cameras."
Le 30 avril dernier, la Nasa a lancé une nouvelle expérience. Baptisée High Definition Earth Viewing (vue de la Terre en HD), elle permet aux internautes de regarder la Terre en haute-définition et en direct grâce à quatre webcams installées sur la Station spatiale internationale.

"Depuis des années, je me pose la même question, une question toute simple, toute bête diront certains: à quoi sert la culture scientifique que nous nous efforçons tous de diffuser ? Qu’avons-nous vraiment à apporter en tant que communicateurs scientifiques ?..."
"Meet Arduino, the tiny microcontroller that’s good at doing what your computer can’t.
The computers we use every day are powerful, but they’re terrible at knowing what’s going on around them. Your laptop isn’t exactly equipped to sense light or moisture, for example. Arduino, on the other hand, is specifically designed to stay keyed in to the outside world. It’s equipped with a board full of inputs and outputs for sensors to simplify communication..."
