The ability to make atomic-level changes in the functional components of semiconductor switches, demonstrated by a team of Oak Ridge National Laboratory, North Carolina State University and University of Tennessee physicists, could lead to huge changes in the semiconductor industry. The results are reported in the June 13 issue of Science.

Semiconductor devices, the building blocks of computing chips that control everything from coffee makers to Mars landings, depend on microscopic solid-sta

Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have developed the world’s first x-ray computed tomography (CT) scanner capable of examining entire core samples at remote drilling sites. The portable device, which employs the same high-resolution imaging technology used to diagnose diseases, could help researchers determine how to best extract the vast quantities of natural gas hidden under the world’s oceans and permafrost.

The scanner images the distribution of gas hydrate

Three decades of research on men’s sexual arousal show patterns that clearly track sexual orientation — gay men overwhelmingly become sexually aroused by images of men and heterosexual men by images of women. In other words, men’s sexual arousal patterns seem obvious.

But a new Northwestern University study boosts the relatively limited research on women’s sexuality with a surprisingly different finding regarding women’s sexual arousal.

In contrast to men, both heterosexual and

Multi-National team of physicists include Weizmann Institute Scientists

Recent results of a joint experiment conducted by 460 physicists from 57 research institutions in 12 countries strongly indicate that the scientists have succeeded in reproducing matter as it first appeared in the universe; this matter is called the quark-gluon plasma. The experiment, called PHENIX and conducted at the Brookhaven National Laboratory on Long Island, New York, has brought together physicists from Br

Researchers at the University of Rochester have produced compelling evidence of how the hand of natural selection caused one species of fruit fly to split into two more than 2 million years ago. The study, appearing in today’s issue of Nature, answers one of evolutionary biologists’ most basic questions–how do species divide–by looking at the very DNA responsible for the division. Understanding why certain genes evolve the way they do during speciation can shed light on some of the least

University of Southampton scientists create a computer agent that aims to make life less complicated

A new computer agent that will work through users’ mobile phones and organise their business and social schedules, has been developed by scientists at the Department of Electronics and Computer Science (ECS) at the University of Southampton.
The agent is an example of how the next generation of World Wide Web will work. An artificial intelligence programme has been devised which a
