Size Matters: Eavesdropping on Sexual Signals

Biologists at the University of California, Riverside, have found that
male crickets growing up in the presence of abundant male song tend to be larger, behave differently, and invest nearly 10 percent more reproductive tissue mass in their testes than male crickets growing up in a silent environment. The subtle modifications of behavior depending on the environment, not genes, means that even in insects, animals are not "programmed" or "hard-wired" to do what they do.

Two University of Pennsylvania
mathematicians have found solutions to a 140-year-old, 7-dimensional equation that were not known to exist for more than a century despite its widespread use in modeling the behavior of gases.

Tiny variations in the isotopic composition of
silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 billion years ago. The new study, published in the journal Science, indicates that water and other key volatiles may have been present in at least some of Earth's original building blocks, rather than acquired later from comets, as some scientists have suggested.

The
use of computational modeling is providing new opportunities to the field of archaeology and can possibly enhance previous findings of how humans and the environment interact.

Brown Geologists Show Unprecedented Warming in Lake Tanganyika
Wed, 19 May 2010 13:39:00 -0500
Geologists led
by Brown University have documented that Lake Tanganyika in east Africa has experienced unprecedented warming in the last century. Using core samples obtained from the lake bed, the team determined the lake is currently the warmest it has been in the last 1,500 years. The warming likely is affecting the valuable fish stocks upon which millions of people depend. Results appear in Nature Geoscience.
