Adiponectin, a protein produced by fat cells, may play a pivotal and counterintuitive role in cardiovascular health for older Americans according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM).

Those who drink in excess of the U.S. Dietary Guidelines (i.e., men who usually drink more than two drinks per day or women who usually drink more than one drink per day) or those who binge drink are at increased risk for the metabolic syndrome, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

WINSTON-SALEM, N.C. – When it comes to risk for a heart attack, having excess fat around the heart may be worse than having a high body mass index or a thick waist, according to researchers from Wake Forest University Baptist Medical Center and colleagues reporting in the August issue of the journal Obesity.

Male injection drug users deported from the United States to Tijuana have four-fold higher odds of HIV infection compared to those living in Tijuana who were not deported there, according to a study to be presented at the International AIDS Conference on August 5, 2008 in Mexico City. The study, funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), will be published in the July 30 issue of the Public Library of Science (PLoS) One.

Paleontologists in 2005 hailed research that apparently showed that soft, pliable tissues had been recovered from dissolved dinosaur bones, a major finding that would substantially widen the known range of preserved biomolecules.

But new research challenges that finding and suggests that the supposed recovered dinosaur tissue is in reality biofilm – or slime.

In vertebrates with separate sexes, sex determination can be genotypic (GSD) or temperature-dependent (TSD). TSD is very common in reptiles, where the ambient temperature during sensitive periods of early development irreversibly determines whether an individual will be male or female. The number of males and females in a population is the sex ratio, a key demographic parameter crucial for population viability.

An enriched extract of the 'Indian Frankincense' herb Boswellia serrata has been proven to reduce the symptoms of osteoarthritis. Research published today in BioMed Central's open access journal Arthritis Research & Therapy has shown that patients taking the herbal remedy showed significant improvement in as little as seven days.

Ultra-miniature bialy-shaped particles — called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City — could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.

Extreme heat or cold is not only uncomfortable, it can be deadly—causing proteins to unravel and malfunction.

For many years now, scientists have understood the molecular mechanisms that enable animals to sense dangerous temperatures; such as extremely high temperatures that directly trigger heat sensor proteins known as TRP channels. However, much more poorly understood is how animals sense very small temperature differences in the comfortable range, and choose their favorite temperature.
