A dangerous level of carbon dioxide and methane gas haunts Lake Kivu, the freshwater lake system bordering Rwanda and the Republic of Congo.
Scientists can`t say for sure if the volatile mixture at the bottom of the lake will remain still for another 1,000 years or someday explode without warning. In a region prone to volcanic [...]

Buyyounouski, M.D., M.S. and presented today at the annual meeting of the American Society for Radiation Oncology [...]

Researchers at The Scripps Research Institute have solved one of biology`s neatest little tricks: they have discovered how a cell`s outer membrane pinches a little pouch from itself to bring molecules outside the cell inside—without making holes that leak fluid from either side of the membrane.
In the cover story of the December 26 issue of [...]

A crew drilling on the Big Island of Hawaii has discovered magma, the molten rock material — never before found in its natural habitat underground — that is the central ingredient in the evolution of planets and the lifeblood of all volcanoes.
The chance discovery far beneath the Earth`s surface gives scientists an unprecedented opportunity to [...]

Black holes can now be thought of as donut holes. The shape of material around black holes has been seen for the first time: an analysis of over 200 active galactic nuclei—cores of galaxies powered by disks of hot material feeding a super-massive black hole—shows that all have a consistent, ordered physical structure that seems [...]

Stepping onto a scale after a calorie-filled holiday season isn`t an activity many 21st-century Americans relish. But in the late 19th century, scales were all the rage at festive gatherings — the 1800s` answer to Guitar Hero.
"A family would think it fun to weigh themselves before and after a big holiday dinner to see how [...]

A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer, researchers report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.
With this technique, researchers at the [...]
