Oceanic bacterial photopigments convert light into biochemical energy
A new energy-generating, light-absorbing pigment called proteorhodopsin is widespread in the world's oceans, say scientists funded by the National Science Foundation (NSF) and affiliated with the Monterey Bay Aquarium Research Institute (MBARI).

UF researchers: rural residents less apt to seek Alzheimer's care from family doctors
In a new study evaluating patterns of health-care use in six Southeastern states, scientists also found that more than 40 percent of people -- urban and rural -- whose forgetfulness and difficulties with ordinary daily tasks could be signs of Alzheimer's were not receiving care for such problems.

Scientists push enzyme evolution into high gear
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have found a way to make a plant enzyme that is 100 times more efficient than similar enzymes found in nature.

Colorado, Arizona and New Mexico students team up on satellite project
Students from the University of Colorado at Boulder, Arizona State University and New Mexico State University are teaming up in a unique space project to design, build and fly three identical satellites in formation to obtain stereo images of small, quickly changing space phenomena like cloud formations, pollution plumes, and dust storms.

Immune co-stimulation and the Kaposi's virus
Viruses of the herpesvirus family have developed numerous innovative strategies to establish themselves in their host by evading, destroying, or redirecting host immune cells.

UGA study shows effects on family when mom has HIV
Rex Forehand, a UGA research professor and Director of the Institute for Behavioral Research, has completed the only study of its kind showing how inner-city families cope with an HIV-infected mother and how they can best move forward.

HIV's deadly assault on immune cells chronicled in step-by-step account of viral invasion
Using sophisticated post-genomic technology, a team of UCSD researchers has looked deep within the body's immune cells and recorded the molecular events triggered by invasion of the human immunodeficiency virus (HIV), creating a detailed account of the devastating progression of cellular injury following HIV infection.

Anglers hoping their favorite fish may become resistant to whirling disease will have to wait longer, according to a recent study published in the Journal of Aquatic Animal Health.

Lake tributaries in Yellowstone National Park allow unique study of whirling disease
Thirteen new whirling disease research projects in eight western states are under way, including a unique study of the disease in the tributaries of Yellowstone Lake in Yellowstone National Park.

Cornell-bred, blight-resistant potato variety -- New York 121 -- is sent to Russia for testing to stave off potato crisis
Russia is on the brink of a potato crisis ignited by the virulent, fungal-like pathogen, called late blight, that was responsible for the 19th century Irish potato famine.

Somatostatin in sexually dimorphic gene expression
Male and female mammals are distinguished not just by their primary sexual characteristics, but also by their different postpartum growth rates and by subtle differences in expression of metabolic genes.

New electronic timber grading - by microwave
Scientists from Australia's national research organisation, CSIRO, have added a new dimension to the grading of timber with the development of high speed scanning using microwave technology.

Lost in virtual space: Gender navigational differences are magnified
Well-documented gender differences in people's ability to navigate and orient themselves in the real world are vastly exaggerated in computer-simulated virtual environments, according to University of Washington researchers

Reexamining iron's role in heart disease
Chemically modified forms of the LDL are thought to serve as the direct source of cholesterol in atherosclerotic plaques, but the nature of the chemical modification that converts native LDL to an atherogenic species in vivo is a matter of much debate.

New method of predicting stroke in heart patients
Researchers at Washington University School of Medicine in St. Louis have developed a formula to predict the risk of stroke in patients with an irregular heart rhythm called atrial fibrillation.
