A computer program called the Never Ending Image Learner (NEIL) is now running 24 hours a day at Carnegie Mellon University, searching the Web for images, doing its best to understand them. And as it builds a growing visual database, it is gathering common sense on a massive scale.

NEIL leverages recent advances in computer vision that enable computer programs to identify and label objects in images,… read more

Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new… read more

DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.

DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more

How unconscious processing improves decision-making

February 15, 2013

New brain imaging research from Carnegie Mellon University provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision making. Published in the journal Social Cognitive and Affective Neuroscience, the study found that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task.

NASA is mulling over a plan to build a robotic spacecraft to grab a small asteroid and place it in high lunar orbit, according to researchers with the Keck Institute for Space Studies in California.

The mission would cost about $2.6 billion and could be completed by the 2020s, New Scientist reports.

The Obama administration has said it also wants to send astronauts to a near-Earth asteroid. One… read more

Fed up with government spying, some people have decided to take matters into their own hands, and are building a user-owned Internet from scratch, using meshnets, New Scientist reports.

These wireless networks are intended to permit secure communication without surveillance or any centralized organization, and ultimately, if their designers get their way, they will span the country.

Each node in the mesh, consisting of a radio transceiver… read more

The Utah Data Center, being built for the National Security Agency, is intended to intercept, decipher, analyze, and store vast swaths of the world’s communications. The heavily fortified $2 billion center should be operational in September 2013.

It has established warrantless listening posts throughout the nation to collect and sift through billions of email messages and phone calls, whether they originate within the country or overseas in a program codenamed… read more

Evidence that photosynthesis efficiency is based on quantum mechanics

January 17, 2014

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis, published in the journal Nature Communications (open access).

The majority of light-gathering macromolecules are composed of chromophores (responsible for the color of molecules) attached to proteins, which carry out the first step of photosynthesis, capturing… read more

Giant black hole could upset galaxy evolution models

A group of astronomers led by Remco van den Bosch from the Max Planck Institute for Astronomy (MPIA) have discovered a black hole that could shake the foundations of current models of galaxy evolution.

At 17 billion times the mass of the Sun, its mass is much greater than current models predict — in particular in relation to the mass of its host galaxy. This… read more

The simple act of saving something, such as a file on a computer, may improve our memory for the information we encounter next, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research suggests that the act of saving helps to free up cognitive resources that can be used to remember new information.

“Our findings show that people are significantly better at… read more

Supplement added to a standard diet improves health and prolongs life in mice

Activating a protein called sirtuin 1 extends lifespan, delays the onset of age-related metabolic diseases, and improves general health in mice. The findings, which appear online February 27 in the Cell Press journal Cell Reports, point to a potentially promising strategy for improving health and longevity.

Sirtuin 1, or SIRT1, is known to play an important role in maintaining metabolic balance in multiple tissues, and studies in… read more

How to prevent diseases of aging

By 2050, the number of people aged over 60 years is projected to be five times that in 1950 (credit: Luigi Fontana, Brian K. Kennedy, and and Valter D. Longo/Nature)

By 2050, the number of people over the age of 80 will triple globally, which could come at great cost to individuals and economies.

Unfortunately, medicine focuses almost entirely on fighting chronic diseases in a piecemeal fashion as symptoms develop, researchers writing in the journal Nature say. Instead, more efforts should be directed to promoting interventions that have the potential to prevent multiple chronic diseases and extend healthy lifespans.… read more
