The site where Europe’s spacecraft are launched into orbit, the Atlantic shoreline of French Guiana, is also the starting point for another hardly less remarkable journey: the epic migration of the critically endangered leatherback turtle.

Scientists have been using tracking sensors to follow the long treks of individual leatherbacks, then overlaying their routes with sea state data, including near-real time maps of ocean currents gathered by satellites including ESA’s ERS-2

Scientists have developed a new screening technique to help them look for genes that change patients’ responses to cancer drugs and other medications.

Researchers looking for such connections confront an enormous hunting ground of approximately 33,000 human genes. Normally their only options for mounting a search in such a vast field are either to rely on anecdotal reports of dramatically altered patient reactions, or to conduct extensive surveys of the genes for all the proteins kn

A nanocrystalline metal is one whose average grain size is measured in billionths of a meter, much smaller than in most ordinary metals. As the grain size of a metal shrinks, it can become many times stronger, but it also usually loses ductility. To take advantage of increasing strength with decreasing grain size, researchers must first understand a fundamental problem: by what processes do nanosized crystals of metal stretch, bend, or otherwise deform under strain?

Independent research groups have discovered novel therapeutic targets in the battle of the bulge

Independent research groups have discovered novel therapeutic targets in the battle of the bulge. By altering the expression of a single — albeit different – gene, Drs. Roger Davis (UMASS Medical School, USA) and Ying-Hue Lee (Academia Sinica, Taiwan) have succeeded in creating two different strains of transgenic mice that don’t gain weight, even when fed fat-laden, high calorie die

Scientists have pinpointed the source of a meteorite from the moon for the first time. Their unique meteorite records four separate lunar impacts.

They are the first to precisely date Mare Imbrium, the youngest of the large meteorite craters on the moon. That date, 3.9 billion years ago, is a new key date for lunar and even terrestrial stratigraphy, the scientists say, because life on Earth would have evolved only after heavy meteorite bombardment ended.

Geologists who fou

For the estimated six to seven million Americans with psoriasis, the warm-weather months of summer might be the most challenging. Instead of being able to cover up their condition with sweaters or pants, psoriasis patients – forced to keep cool by wearing short-sleeved shirts and shorts – find themselves revealing the raised, thickened patches of red skin and silvery-white scales that they try so desperately to hide. Now, new treatment advances offer patients more hope in finding a life-long solutio
