Single-molecule manipulation for the masses

Scientists have developed a new massively-parallel approach for manipulating single DNA and protein molecules and studying their interactions under force. The finding appears in the June 2 issue of Biophysical Journal.

Study identifies surgical means for improving kidney cancer survival

When kidney cancer spreads to other body parts, patients usually receive a poor prognosis. A new Mayo Clinic study examined the benefits of surgical treatment of kidney cancer, specifically renal cell carcinoma, and how patients saw improved prognosis of their cancer. These findings were presented today at the American Urological Association meeting in San Francisco.

'Mal-intent' may be the future of security

If Bob Burns is correct, terrorists may betray themselves someday by jiggling on a Nintendo Wii balance board, blinking too fast, curling a lip like Elvis -- or doing nothing at all. Burns and his team of scientists are researching whether video game boards, biometric sensors and other high-tech devices can be used to detect distinct nonverbal cues from people who harbor "mal-intent," or malicious...

New gecko species identified in West African rain forests

The West African forest gecko, a secretive but widely distributed species in forest patches from Ghana to Congo, is actually four distinct species that appear to have evolved over the past 100,000 years due to the fragmentation of a belt of tropical rain forest , according to a report in this week's issue of the journal Proceedings of the Royal Society B.

Ralink Unveils Next-Gen Dual-Band 2x2 802.11n/Bluetooth 3.0+HS Combo Module

Ralink Technology, a developer of high performance wired and wireless networking solutions, today announced the RT3592BC8, the world's only chipset capable of simultaneous 300 Mbps 2x2 MIMO dual band 802.11n and Bluetooth 3.0+HS operation. The half MiniCard solution for PCs, notebooks, netbooks and connected mobile devices delivers an unprecedented level of performance and intelligent coexistence...

Cognitive ability, not age, predicts risky decisions

Just because your mother has turned 85, you shouldn't assume you'll have to take over her financial matters. She may be just as good or better than you at making quick, sound, money-making decisions, according to researchers at Duke University.

How reliable is prognostic research? A case study of C-reactive protein in coronary artery disease

Prognostic markers provide tools for discriminating between groups of patients who are at different risks of a particular outcome, and therefore should help clinicians to manage disease. In a comprehensive overview of studies looking at one such proposed marker, C-reactive protein (CRP) in coronary artery disease, Harry Hemingway and colleagues, from University College London, show that despite...

In solar power, N.J. shines

If NFI Industries' calculations are right, the three acres of solar panels just installed on the roof of its Cherry Hill, N.J., headquarters will save $750,000 in energy costs over 15 years and become a green feather in its cap. The 1.32-megawatt project could also be a launchpad.

Lasers help researchers predict birds' preferred habitat

Every spring, migratory birds like the Black-throated Blue Warbler journey from tropical Caribbean or South American refuges to North American forests. But which forest patch will they call home this year? And, how can researchers predict where they choose to nest?
