Two teams of neuroscientists have reconstructed the wiring of tiny pieces of the brain and related it to the function of individual cells. To understand how the brain works, you need to know what connects to what. But it has so many cells, making so many connections, that this is a big challenge.

New research shows that certain areas in our brain serve as bottlenecks that can limit very different cognitive processes.

UCLA researchers have developed LCDs with photovoltaic polarizers that can turn light wasted by the screen back into energy for the phone. Since screens use the most battery power, the technique could lead to significant increases in battery life.

Scientists report the discovery of antimatter particles held by the Earth's magnetic field, created by collisions of high-energy cosmic rays with particles from the upper atmosphere.

Mantle plumes have long been thought to affect the motion of tectonic plates, but teasing out evidence for the idea has been difficult. A paper published in Nature may finally provide a solid example.

Markus Kayser’s Solar Sinter project takes the desert’s two most abundant resources, sunlight and sand and puts them to work manufacturing glass objects. Kayser loads the sand into a solar-powered 3-D printer where it serves as the raw material for glass.

Researchers pump a cell full of Green Fluorescent Protein, then pump that full of energy, producing the first living cell that's also a laser.

An invisible revolution has taken place is the way we use the net, but the increasing personalisation of data by search engines such as Google threatens to limit our access to information and enclose us in a self-reinforcing world view, writes Eli Pariser in an extract from The Filter Bubble

Juntos Finanzas, a budget-by-text program started at Stanford with a group of janitorial workers, is part Mint.com, part Weight Watchers. Now it's making real changes in the lives of lower-income workers.

L'annonce en novembre dernier par la Nasa d'une découverte qui allait changer la recherche de vie extraterrestre et les débats en ligne entre scientifiques qui ont suivi marquent une révolution dans l’évaluation des études scientifiques.

As with many areas of public interest, the common wisdom surrounding energy conservation consists of myths and legends. I found the list below, proposed alternatives to nuclear energy. I was curious whether their claims were true. Mouse over each claim to read and play with an interactive analysis.

Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant. Of course, the traditional choice of circle constant is π—but, as mathematician Bob Palais notes in his delightful article “π Is Wrong!”

Bang is the BBC's guide to popular science. Watch videos and do real experiments at home.

An explainer is not “everything you need to know about X.” But it is the starting point, the big picture. So while we hope that you enjoy the song, what we really want you to do is read more about hydraulic fractured drilling, so you can truly understand “what the frack is going on.”

Le monde scientifique est en émoi. Deux biologistes français ont constaté que le casque exubérant porté par certains insectes est, en réalité, une troisième paire d'ailes transformée. Cette découverte met à bas un dogme absolu : à savoir que les insectes portent deux paires d'ailes.

Interdisciplinary research (“IDR”) is often trumpeted as essential for scientific and technological advancement. This website offers a novel tool, the overlay maps of science, as a method to explore the degree of interdisciplinarity.

The recent ICT revolution has given birth to a parallel world of digital traces. This change affects a wide number of contexts of collaborative knowledge creation, from casual discussions, political arguments, to scientific elaboration and participative decision-making.

VisionLink Explorer® est un composant logiciel spécialisé qui permet d'explorer des masses d'informations de toute nature en explorant leurs associations. Le démonstrateur que PIKKO met à votre disposition contient des données tirées des entreprises du CAC40.

Rural farmers in Africa can now learn new farming techniques through simple animations that can be viewed on mobile phones.

D3 allows you to bind arbitrary data to a Document Object Model (DOM) then apply data-driven transformations to the document.You can use D3 to generate a basic HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction.

Soutenue par les gouvernements successifs, ce que d’aucuns appellent l’exception française sur le nucléaire n’a jamais été remise en cause depuis le lancement du Plan Messmer en 1973.
