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.
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

The Makerbot Replicator 2, a second generation of MakerBot’s wildly popular Replicator 3D printer, is now faster, quieter, and more rigid than the original, Make reports.
The Replicator now sports a sleek modern look with an all-black sheet metal frame and PVC side panels that are removable, customizable, and allow for easy cleaning of any excess material.
A larger, more responsive LCD panel on the front… read more

Two high-profile entrepreneurs say they want to put a DNA sequencing machine on the surface of Mars in a bid to prove the existence of extraterrestrial life.
In what could become a race for the first extraterrestrial genome, researcher J. Craig Venter said Tuesday that his Maryland academic institute and company, Synthetic Genomics, would develop a machine capable of sequencing and beaming back DNA data… read 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

Researchers have made the first stable lithium-air batteries, Science NOW reports. They may one day give electric cars a driving range similar to today’s gas guzzlers.
Lithium-air batteries have potential to store 10 times more energy than the best lithium-ion batteries on the market today, but have been unstable, falling apart after a few charges.
So researchers at the University of St Andrews in the United… read more

An international team of neuroscientists and robotics engineers have demonstrated the first direct remote brain-to-brain communication between two humans located 5,000 miles away from each other and communicating via the Internet, as reported in a paper recently published in PLOS ONE (open access).
In India, researchers encoded two words (“hola” and “ciao”) as binary strings and presented them as a series of cues on a computer monitor. They recorded… read more

The same basic functional elements are used throughout the cortex and understanding how one area works in detail will uncover fundamentals that apply to the other areas as well, scientists at the Allen Institute for Brain Science reported in the latest issue of the journal Nature.
Human brains share a consistent genetic blueprint, and possess enormous biochemical complexity, they said, based on the first deep and large-scale… 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

Australian researchers have developed a handheld “BioPen” that will allow surgeons to precisely design and deliver customized bone and other implant materials (live stem cells and growth factors) at the time of surgery to regenerate bone, cartilage, muscle, or nerve tissue.
Here’s how it works:
- Similar to a multi-material 3D printer, the BioPen delivers stem cells embedded in a biopolymer carrier (such as alginate, a seaweed extract), protected

By analyzing the movement of its host star, Kepler 78, the scientists determined that the exoplanet is about 1.7 times as massive as the Earth.
From the same measurements, they calculated that the planet’s density is 5.3 grams… read more
