Blood levels of a certain protein in cholesterol may be a better predictor than total cholesterol in determining a woman's certain protein as well as a man's cholesterol risk for heart disease, according to a report in today's Arteriosclerosis, Thrombosis and Vascular Biology: Journal of the American Heart Association.

'Frustrated' Lubricant Molecules Offer New Strategy For Reducing Friction In Mechanical Devices
For decades, researchers have struggled to reduce friction in mechanical systems by improving the chemical composition of the lubricants used to separate moving parts.

Ecological Consequences Of Jasmonate-Induced Responses For Plants In Native Populations
Herbivore attack is widely known to reduce food quality and to increase chemical defenses and other traits responsible for herbivore resistance.

Income Inequality's Death Toll: 140 Per 100,000 Population
Unequal income distribution in U.S. metropolitan areas is linked to almost 140 deaths per 100,000 population, according to a new study.

Long-Term Exercise May Help To Protect Arteries
Researchers have shown that long-term exercise may help fight atherosclerosis, the disease process that obstructs blood vessels and triggers heart attacks and strokes.

Minuscule Ocean Plants Help Stabilize Earth's Atmosphere, Climate
Evolving into diverse forms over billions of years, tiny one- celled marine plants and bacteria have, up to now, successfully interacted with the changeable physics and chemistry of the land and sea to stabilize to a surprising extent the relative concentrations of Earth's atmospheric gases, according to a report in the July 10 issue of the journal Science.

Radio Signals Give New Spectrum For Cholesterol Lipoprotein Readings
A new laboratory test can detect levels of 15 different blood cholesterol-containing particles called lipoproteins, an advance that will help paint a clearer picture of a person's risk of heart disease than the cholesterol blood tests now used, scientists say.

Pediatric Laboratory Receives Mass Spectrometer For Leukemia Research
A sophisticated new instrument in a pediatrics laboratory at UT Southwestern Medical Center at Dallas will enable physicians and pharmacologists to refine their research on the side effects of chemotherapeutic drugs used to treat children who have leukemia.

Computer Program Provides New Strategies For Drug War
A new computer program developed at Purdue University may help government officials wage the war on drugs.

Income Inequality Is Directly Related To High Mortality Rates
University of Michigan epidemiologists shows that the size of the gap between the rich and the poor may tell us more about the health status of Americans than the usual economic indicators financial analysts and social scientists typically rely on.

Walking Or Bed Rest OK For First Stage Of Labor, UT Southwestern Research Shows
In the largest study of its kind, UT Southwestern Medical Center at Dallas obstetrics and gynecology researchers have concluded that walking during the first stage of labor is neither harmful nor beneficial to the mother or baby.

Authors: Research Makes Case For Better OSHA Enforcement
Current attempts in Congress to substantially alter and diminish the 1970 Occupational and Safety Act and the agency responsible for enforcing it are somewhat misguided, public health experts say.
