The life-extending properties of caloric restriction may be due not only to fewer calories in the diet, but also to just the right mix of essential amino acids, a study of fruit flies by University College London researchers has found. Adding only the essential amino acid methionine (instead of all essential amino acids) allowed for egg-laying without reducing lifespan, the team found.

Harvard and MIT researchers have demonstrated a way to build more powerful artificial visual systems, taking inspiration from screening techniques in molecular biology (a multitude of candidate organisms or compounds are screened in parallel to find those that have a particular property of interest). "Reverse-engineering a biological visual system--a system with hundreds of millions of processing units--and building an artificial system that works... More

Intel Corp. has re-positioned its "tera-scale" processor R&D efforts, moving towards a more mainstream, x86-based multicore design instead of a proprietary technology.Intel has demonstrated an experimental, 48-core processor--or "single-chip cloud computer" (because it resembles the organization of datacenters used to create a "cloud" of computing) based on a 45-nm process using high-k and metal-gate technology. In the future, Intel's "single-chip... More

A method for creating nanowire transistors with layers of silicon and germanium sharply defined at the atomic level has been developed by researchers at IBM, Purdue University and UCLA.The nanowires are "grown" vertically, so they have a smaller footprint, which could make it possible to fit more transistors on a chip, extending Moore's law.

Evidence of a deep biological link between human music and speech has been found by Duke University neuroscientists.They found that the musical scales most commonly used over the centuries are those that come closest to mimicking the physics of the human voice, and that we understand emotions expressed through music because the music mimics the way emotions are expressed in speech.The showed that the harmonic structure of vowel tones forms the bas...

Nanosphere has developed a device called Verigene that can detect genetic variations in blood that modulate the effectiveness of some drugs, allowing for drug-prescription decisions.Verigene uses a combination of microfluidics and nanotechnology, housed in a single plastic cartridge, to pull DNA from a blood sample and then screen it for the relevant sequences. It could be run in a doctor's office.(Nanosphere) (Source: http://www.technologyrevie... More

Mice created from two female genome lived an average of 186 days longer (a third longer) than control mice created from the normal combination of a male and female genome, Japanese scientists have found. The study may give an answer to fundamental questions: whether longevity in mammals is controlled by the genome composition of only one or both parents, and why women are at an advantage over men with regard to the lifespan.

As part of a project to demonstrate the potential of 3D mapping, lasers were fired at the coastal resort of Bournemouth in southern England from the ground and from the air to capture the height of buildings, trees and other features, using a technique called Lidar.Adding information from aerial photos and traditional surveys produced a full-color 3D map, built up from more than 700 million points. The map is accurate to 4 centimeters in x, y and ... More

Believers subconsciously endow God with their own beliefs on controversial issues, University of Chicago researchers have found.

Scientists have grown meat in the laboratory for the first time. Experts in Holland used cells from a live pig to replicate growth in a petri dish.They initially extracted cells from the muscle of a live pig. Called myoblasts, these cells are programmed to grow into muscle and repair damage in animals. The cells were then incubated in a solution containing nutrients to encourage them to multiply indefinitely. The advent of "in-vitro" or cultured m... More
