(Phys.org) —Scientists use scanning electron microscopes (SEMs) to study tiny structures in small organisms. SEMs can only work in a high vacuum, and exposure to such a vacuum normally causes living things to die very ...
(Phys.org) —In August 2011, researchers from the U.S. Department of Agriculture were presented with a serious, and potentially very costly, puzzle in Kennewick, Wash. Since Kennewick lies within a region near the heart ...

(Phys.org)—Researchers studying Drosophila pachea, a species of fruit fly that lives only in the Sonoran desert, have discovered why it is that the fly is wholly dependent on a single cactus species. It's due, they write ...
New microscope enabled scientists at EMBL Heidelberg to film a fruit fly embryo, in 3D, from when it was about two-and-a-half hours old until it walked away from the microscope as a larva.

On Earth all biology is subjected to gravity. Some biological systems require gravity for correct orientation (geotropism: plants grow up, roots grow down). In the absence of gravity even human biology is affected: astronauts ...
