Frictional heating explains plumes on Enceladus
05-16-2007 · EurekAlert!Rubbing your hands together on a cold day generates a bit of heat, and the same process of frictional heating may be what powers the geysers jetting out from the surface of Saturn's moon Enceladus, according to a new study.

- Scientists propose alternate model for plume on enceladus
12-14-2006 · EurekAlert!
What's causing all the commotion on Enceladus?Last year, when the Cassini spacecraft discovered an enormous plume erupting on Enceladus, one of Saturn's moons, scientists speculated that liquid water lay at shallow depths beneath the icy surface.Now, as reported in the Dec. 15 issue of the journal Science, researchers have proposed an alternate model to account for this spectacular plume.

- Scientists explain how insulin secreting cells maintain their glucose sensitivity
09-05-2007 · EurekAlert!
Scientists at the leading Swedish medical university Karolinska Institutet have now disclosed the mystery how the insulin-secreting cells maintain an appropriate number of ATP sensing ion channel proteins on their surface. This mechanism, which is described in the latest issue of Cell Metabolism, explains how the human body can keep the blood glucose concentration within the normal range and thereby avoid the development of diabetes.

- A study proposes a new universal rule to explain the equilibrium of plant populations
09-18-2007 · EurekAlert!
A study financed by the BBVA Foundation and conducted by scientists Carlos Duarte, Nuria Agustм and Nuria Marbа from the Mediterranean Institute for Advanced Studies (CSIC - University of the Balearic Islands) has allowed the first-time formulation of a universal rule that explains the equilibrium of plant communities, showing how plants assure the survival of their species whether their lives last a day or are prolonged over centuries.

- Study explains why patients with OSA are at higher risk for cardiovascular disease
06-01-2007 · EurekAlert!
Researchers have found that patients with obstructive sleep apnea have higher levels of a type of dead cells (apoptotic cells) from the lining (endothelium) of their blood vessels circulating in their bloodstream than people who do not have OSA. The finding may help explain why those with OSA are at higher risk for cardiovascular disease.

- Hot spot on Enceladus causes plumes
12-17-2007 · EurekAlert!
Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so hot intellectually hot, it's smokin'. The hot spot is causing plumes of ice and vapor to arise above Enceladus, says Washington University's William B. McKinnon.
