Researchers at the University of California, San Diego (UCSD) School of Medicine have identified a previously unknown component of the body’s cellular garbage disposal called the ubiquitin system, which is responsible for regulation of cell function by removal of abnormal and unneeded proteins.

Published in the July 8, 2003 issue of Proceedings of the National Academy of Sciences, the study provides the first description of a molecule called GAIP interacting protein N terminus (GIPN)

University of Delaware marine scientists are now working aboard the 420-foot U.S. Coast Guard icebreaker Healy on a National Science Foundation project to track the fresh water flowing out of the Arctic Ocean into the Atlantic. This fresh water, from melting ice and rivers, affects the salinity and circulation of the ocean and thus has a major influence on the Earth’s climate.

“Freshwater discharge from the Arctic to the North Atlantic is a crucial factor controlling global climate,”

Virginia Tech wood scientists hope that their vacuum-drying project will benefit wood pallet and container manufacturers and hardwood sawmill businesses across the nation.

“The vacuum controlling system eliminates the need for a heating system, saves energy, and does not release ozone-depleting chemicals into the earth’s atmosphere,” says Zhangjjng Chen, one the researchers working on the project at the Center for Unit Load and Design in the wood science and forest products depa

NASA satellites’ “eyes” above Earth are providing scientists and fire managers with powerful monitoring tools. NASA is providing the “big picture” needed to understand how fires behave before, during, and after damage has been done. A suite of NASA satellites, flying in coordinated fashion, offers the unparalleled insight only possible from space.

Fire season is underway in the American West, with wildfires raging in at least 11 states, challenging fire agencies and their limite

In a river valley just southwest of Mexico City stands a small patch of teosinte – a wild, weedy grass thought to be the ancient ancestor of corn. As a gentle breeze blows gene-carrying pollen from a nearby crop of maize to its wild relative, the genetic integrity and even survival of this ancient plant and others could be jeopardized, according to new mathematical models.

The models, described in the July 23 online edition of the Proceedings of the Royal Society of London and develo

New research on dwarf spheroidal galaxies by a team of astronomers at the University of Cambridge promises a real astronomical first: detection, for the first time, of the true outer limits of a galaxy.

The team is presenting today (23 July 2003) at the 25th General Assembly of the International Astronomical Union (IAUXXV) in Sydney, Australia. The research could provide the key to understanding how larger galaxies were formed, including our own Milky Way galaxy.
