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

Turkish engineers are working on "the Anaposta," which would provide email accounts with a quota of 10 gigabytes to all of Turkey's 70 million citizens at birth, with the email address written on his/her identity card; and a Turkish search engine with better "editorial judgement" than Google (i.e., omit whatever leaders of the Muslim world find offensive).This is consistent with Article 301 of the Turkish Constitution, which restricts anyone from...

Believers subconsciously endow God with their own beliefs on controversial issues, University of Chicago researchers have found. "These findings help explain why supernatural religious agents are often attributed a physical form and issue edicts that resemble the social practices of the culture from which they emerge," says Jordan Grafman of the US National Institute of Neurological Disorders and Stroke.

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

(Harvard University) An international team of applied scientists from Harvard, Hamamatsu Photonics, and ETH Zurich have demonstrated compact, multibeam, and multi-wavelength lasers emitting in the invisible part of the light spectrum (infrared). By contrast, typical lasers emit a single light beam of a well-defined wavelength. The innovative multibeam lasers have potential use in applications related to remote chemical sensing pollution monitoring... More

A new study by Maastricht University helps to explain what happens in the brain that allows us to perceive a physically interrupted sound as being continuous.The researchers found that spontaneous modulations in slow evoked auditory cortical (theta) oscillations may determine the perceived continuity of fragmented sounds in noise. They suggest that their results might inspire future design of devices to assist people with hearing deficits. (Sour... More

Fingerprint ridges and whorls process vibrations in the skin to make them easier for nerves to pick up, University of Paris researchers have found. Fingerprints act like signal processors, conditioning the mechanical vibrations so that the Pacinian corpuscles can best interpret them. It's this optimisation process that allows us to sense textures with a spatial resolution far smaller than the distance between Pacinian corpuscles in the skin, an ex... More

A prototype device that uses "cold atmospheric plasma" to rid hands, feet, or even underarms of bacteria, including the hospital superbug MRSA, has been developed by Max Planck Institute for Extraterrestrial Physics researchers.The team says that an exposure to the plasma of only about 12 seconds reduces the incidence of bacteria, viruses, and fungi on hands by a factor of a million, a number that stands in sharp contrast to the several minutes ho...

(Helmholtz Association of German Research Centres) The concept of confinement is one of the central ideas in modern physics. The most famous example is that of quarks which bind together to form protons and neutrons. Now Prof. Bella Lake from Helmholtz-Zentrum Berlin together with an international team of scientists report for the first time an experimental realization and a proof of confinement phenomenon observed in a condensed matter system.
