Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.

Researchers from University of California, Berkeley and the University of British Columbia have created a computer program that can rapidly reconstruct “proto-languages” — the linguistic ancestors from which all modern languages have evolved.
These earliest-known languages include Proto-Indo-European, Proto-Afroasiatic and, in this case, Proto-Austronesian, which gave rise to languages spoken in Southeast Asia, parts of continental Asia, Australasia and the Pacific.
Ancient languages hold… read more
By synchronizing 98 tiny cameras in a single device, engineers from Duke University and the University of Arizona have created a prototype camera that could capture up to 50 gigapixels of data (50,000 megapixels) and images with unprecedented detail.
The AWARE-2 camera’s resolution is five times better than 20/20 human vision over a 120 degree horizontal field.
By comparison, most consumer cameras are capable of taking photographs with sizes ranging… read more

These innovations stand alone to help transform the quality and speed of care delivered to patients through individualized, evidence based medicine, says IBM.
For more than a year, IBM has partnered separately with WellPoint and Memorial Sloan-Kettering to… read more

Lawrence Livermore National Laboratory chemists have developed a new flexible “aerogel” — stuff so light it has been called “solid smoke” — described as the world’s lightest solid material and best solid insulating material.
“The new aerogels are up to 500 times stronger than their silica counterparts,” said Mary Ann B. Meador at the annual meeting of the American Chemical Society.
“A thick piece actually can support the… read more

A new study from MIT neuroscientists has found that for the first time, one of the latest generation of “deep neural networks” matches the ability of the primate brain to recognize objects during a brief glance.
Because these neural networks were designed based on neuroscientists’ current understanding of how the brain performs object recognition, the success of the latest networks suggests that neuroscientists have a fairly accurate grasp of… read more

The smallest transistor ever built has been created using a single phosphorous atom by an international team of researchers at the University of New South Wales, Purdue University and the University of Melbourne.
The latest Intel chip, the “Sandy Bridge,” uses a manufacturing process to place 2.3 billion transistors 32 nanometers apart.
A single phosphorus atom, by comparison, is just 0.1 nanometers across, which would significantly reduce… read more

The test is the first purely sensory assessment to be strongly correlated with IQ and may provide a non-verbal and culturally unbiased tool for scientists seeking to understand neural processes associated with general intelligence.
“Because intelligence is such a broad construct, you can’t… read more

With a new lightweight material known as UltraRope, however, elevators should now be able to travel up to one kilometer (3,281 ft) continuously, Gizmag reports.
Using traditional steel lifting cables, they can’t go farther than 500 meters (1,640 ft) in one vertical run.

Researchers at Scripps Institution of Oceanography at UC San Diego have developed a method for greatly enhancing biofuel production in tiny marine algae by genetically engineering a key growth component in biofuel.
The researchers say a significant roadblock in algal biofuel research surrounds the production of lipid oils, the fat molecules that store energy that can be produced for fuel: algae mainly produce the desired… read more

Researchers in EPFL’s Signal Processing 5 Laboratory (LTS5), working with PSA Peugeot Citroën, have developed an emotion detector based on the analysis of facial expressions in a car, using an infrared camera placed behind the steering wheel.
The researchers say they can read facial expressions and identify which of the seven universal emotions a person is feeling: fear, anger, joy, sadness, disgust, surprise, or… read more

In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power.
In a new study, researchers from Duke University’s Pratt School of Engineering used computational methods to identify dozens of platinum-group alloys that were previously unknown to science but could prove beneficial in a wide range of applications.
Platinum… read more
