New Radar Maps of Moon 70

SpaceAdmiral writes to mention that NASA has some new high-resolution radar maps of the Moon obtained by the Jet Propulsion Laboratory. The new images have also been used to create a simulation of the Moon's day and a movie of a Moon landing from the point of view of the astronaut. "NASA is eying the Moon's south polar region as a possible site for future outposts. The location has many advantages; for one thing, there is evidence of water frozen in deep dark south polar craters. Water can be split into oxygen to breathe and hydrogen to burn as rocket fuel--or astronauts could simply drink it. Planners are also looking for 'peaks of eternal light.' Tall polar mountains where the sun never sets might be a good place for a solar power station."

Journal Journal: Fat cells send message that aids insulin secretion

The body's fat cells help the pancreas do its job of secreting insulin, according to new research. This previously unrecognized process ultimately could lead to new methods to improve glucose metabolism in type 2 diabetic or insulin-resistant people. In a study using laboratory mice, published in the November 7, 2007 issue of Cell Metabolism, scientists at the Washington University School of Medicine report that fat cells releas
