If your parents had coronary heart disease before age 60, the walls of your neck arteries are more likely to be thicker, putting you at higher risk of heart disease, too, researchers report in today´s rapid access issue of Circulation: Journal of the American Heart Association.

Compared with people with no parental history of early-onset coronary heart disease (CHD), those with at least one parent who had a heart attack or other coronary event such as chest pain before age 60, had th

Chemists at Rice University have identified a chemical process for cutting carbon nanotubes into short segments. The new process yields nanotubes that are suitable for a variety of applications, including biomedical sensors small enough to migrate through cells without triggering immune reactions.

The chemical cutting process involves fluorinating the nanotubes, essentially attaching thousands of fluorine atoms to their sides, and then heating the fluoronanotubes to about 1,000 Celsi

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
