The number of potentially habitable planets in our galaxy is greater than previously thought, according to a  new analysis by a Penn State researcher, and some of those planets are likely lurking around nearby stars.

“We now estimate that if we were to look at 10 of the nearest small stars we would find about four potentially habitable planets,” said Ravi Kopparapu, an Evan… read more

An EPFL student, Peugeot Citroën, has developed a video analysis algorithm able to estimate the level of a driver’s fatigue based on the degree of eyelid closure and has built a prototype to test it in real driving conditions.

Nearly a third of highway accidents are caused by fatigue. Nowadays, there exist several attention detection systems for drivers, such as detection of loss of vehicle… read more

A NASA-funded new approach to power-beaming solar-power satellites has been developed by John Mankins, who led the first NASA solar-power-satellite development team in the 90s.

Called the SPS-ALPHA (Solar Power Satellite via Arbitrarily Large PHased Array), this “first practical solar-power satellite concept” uses a novel “biomimetic” approach.

Mankins said that this project would make possible the construction of huge platforms from tens of thousands of small elements that can deliver… read more

EdX, the online learning initiative founded by Harvard University and the Massachusetts Institute of Technology (MIT) and launched in May, announced today the addition of the University of California, Berkeley to its platform.

UC Berkeley will offer two courses on edX this Fall — on AI and software — and the university will also serve as the inaugural chair of the to-be-formed “X University” Consortium.… read more

Neuromorphic ‘atomic-switch’ networks function like synapses in the brain

August 19, 2014

atomic-switch network

Researchers in the U.S. and Japan have developed a self-assembled neuromorphic (brain-like) device comprising more than a billion interconnected “atomic-switch” inorganic synapses embedded in a complex network of silver nanowires.

The researchers are located at the California NanoSystems Institute (CNSI) at the University of California, Los Angeles (UCLA) and the International Center for Materials Nanoarchitectonics (MANA) at the National Institute forread more

European scientists have built the first atlas of white-matter microstructure in the human brain in a project called CONNECT (Consortium of neuroimagers for the non-invasive exploration of brain connectivity and tracts).

The new atlas combines 3D images from the MRI scans of 100 brains of volunteers. To achieve this, the scientists developed advanced diffusion… read more

By studying the injuries and aptitudes of Vietnam War veterans who suffered penetrating head wounds during the war, researchers have found that brain regions that contribute to optimal social functioning are also vital to general intelligence and emotional intelligence.

This finding, reported in the journal Brain, bolsters the view that general intelligence emerges from the emotional and social context of one’s life.

“We are trying to understand the nature… read more

The notion that 3D printing will on any reasonable time scale become a “mature” technology that can reproduce all the goods on which we rely is to engage in a complete denial of the complexities of modern manufacturing, unless you’d like everything made out of plastic, says Technology Review | Mim’s Bits blog.

Microsoft is preparing a Siri-like personal voice assistant based on Bing, code-named Cortana, for Windows Phone,  eWeek reports. (Cortana is a holographic AI construct that figures prominently in the Halo video game series.)

Like its Halo counterpart, Cortana “will be able to learn and adapt, thanks to machine-learning technology and the ‘Satori’ knowledge repository powering Bing,” according to ZDNet’s Mary Jane Foley.

Satori, which… read more

Simulated attack on the US power grid planned for Wednesday — Thursday
