The mid-Pliocene warm period is considered a potential analog of future climate. The intensity of the sunlight reaching the earth, the global geography, and carbon dioxide concentrations were similar to present. Furthermore, many mid-Pliocene species are extant helping paleotemperature proxies calibration. Model simula...

Throughout the 1950s, Blumberg traveled the world taking human blood samples, to study the genetic variations in human beings, focusing on the question of why some people contract a disease in a given environment, while others do not.

The total precipitation on Antarctica, averaged over the entire continent, is about per year (Vaughan et al., "J. Clim.", 1999). The actual rates vary widely, from high values over the Peninsula (15 to 25 inches a year) to very low values (as little as in the high interior (Bromwich, "Reviews of Geophysics", 1988). Are...

In 2000, John Pendry was the first to identify a practical way to make a left-handed metamaterial, a material in which the right-hand rule is not followed. Such a material allows an electromagnetic wave to convey energy (have a group velocity) against its phase velocity. Pendry's idea was that metallic wires aligned al...
