Genes expose secrets of sex on the side
...n, the researchers report. More men than women get squeezed out of the mating game. As a result, twice as many women as men passed their genes to the next generation. "It is a pattern that's built up over time. The norm through human evolution is for more women to have children than men," said Jason Wilder......scuss the possibility of the sagebrush biome being squeezed by desert-like plants from the south and trees moving downslope from mountains in the talk, "Climate change implications for sagebrush ecosystems."

...ithful record, rocks that haven't been twisted and squeezed and metamorphosed and otherwise altered,'' Lowe says. ''We're looking back just about as far as the sedimentary record goes.''

...ly iron salts, or ferric hydroxide, that was being squeezed out of the ice sheet. The phenomenon came to be called Blood Falls and its origin has puzzled researchers ever since.

... samples quickly showed the white-footed mouse had squeezed out the prairie deer mouse from its dominant position, diminishing the samples needed to do a comparative study, so Pergams and Nyberg focused attention on the white-footed mouse. "This intensified focus resulted in our discovery of rapid evolution,......Wattrus and his colleagues conclude that the water squeezed out by syneresis through a more compact crust may be the trigger that formed the rings. Geologic conditions associated with retreating glaciers and processes like syneresis caused the lower sediment layer to become mobile and the overlying sediments ...Field Museum uncovers evidence behind man-eating; revises legend of its infamous man-eating lions

...e cell wall of the E. coli. The viral DNA is then squeezed through the tail into the host. The E. coli, thus infected, starts to make only new phage particles and ultimately dies. "Our research described for the first time the structure of phage baseplate proteins and their role in cutting through the host ......ss. When whales and dolphins dive, nitrogen gets squeezed out of their lungs and into the bloodstream, saturating the surrounding tissue. The longer and deeper they dive the more dissolved gas accumulates in their bodies.

... rocks as they are carried to great depth and thus squeezed in the collision zone. When fluid pressures in the crust approach the weight per unit area of the overlying rock (this is called lithostatic pressure), the overlying crust is effectively floating. In this circumstance faults can move under much less ......vich, a collaborator on the study, said creating a squeezed state of atoms is like playing a game of modified ... puck is made of adeformable material, it could be squeezed into a long, thin, cigar-like shape.

This increased the flavonoids more than five-fold, making them as potent as the much greater amount found in red wine.

The authors give a number of suggestions using existing knowledge to reduce the environmental impact of agriculture and still increase productivity.
