October 9, 2007 07:51 AM - Associated Press

France's Albert Fert and German Peter Gruenberg won the 2007 Nobel Prize in physics on Tuesday for a discovery that lets billions of computer users store reams of data on computer hard drives.

The technology "can also be considered one of the first real applications of the promising field of nanotechnology," which deals with extremely small devices, the Royal Swedish Academy of Sciences said in its citation.

New Study Shows Genetically Engineered Corn Could Pollute Aquatic Ecosystems
October 8, 2007 06:56 PM -

BLOOMINGTON, Ind. -- A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published this week by the journal Proceedings of the National Academies of Sciences.

Researchers, including Todd V. Royer, an assistant professor in the IU School of Public and Environmental Affairs, established that pollen and other plant parts containing toxins from genetically engineered Bt corn are washing into streams near cornfields.

They also conducted laboratory trials that found consumption of Bt corn byproducts produced increased mortality and reduced growth in caddisflies, aquatic insects that are related to the pests targeted by the toxin in Bt corn.

Liverpool, UK - Embrionic stem (ES) cells from a wood mouse into the early embryo of a house mouse, an international team of scientists has produced normal healthy animals made up a mixture of cells from each the two distantly related species. This is the first time that stem cells from one mammalian species have been shown to contribute extensively to development when introduced into the embryo of another, very different species.

Santa Cruz, California -  A massive project to map a distant region of the Universe in multiple wavelengths--from x-rays through ultraviolet, visible, infrared, and radio waves--is releasing its data this week to both fellow scientists and the general public. It is the first data release from the AEGIS survey and the  first release of multiwavelength data to take advantage of the capabilities of Google Sky, a new feature of Google Earth.

Why Do Males and Females Frequently Differ in Body Size and Structure?
October 8, 2007 03:58 PM - Paul Schaefer, ENN

RIVERSIDE, Calif. - Males and females frequently differ in body size, form and structure. But how did these differences develop? Despite decades of study by evolutionary biologists - the answer isn't clear.

A new book called Sex, Size & Gender Roles: Evolutionary Studies of Sexual Size Dimorphism (Oxford University Press, 2007). brings together the latest research findings in evolutionary biology to help explain gender differences in a variety of organisms, including mammals, birds, reptiles, amphibians, insects, spiders and flowering plants. The book was edited in part by a UC Riverside biology professor Daphne Fairbairn.
