The humble white button mushroom (Agaricus bisporus) has as much, and in some cases, more anti-oxidant properties than more expensive varieties.

A study published online today in Genome Research (www.genome.org) describes new insights into Legionella pneumophila, the bacteria responsible for most cases of Legionnaires’ disease. This report investigates the genetic background of L. pneumophila, provides clues to the evolution and emergence of this pathogen, and describes the identification of a worldwide-distributed epidemic clone.

Very young brains process memories of fear differently than more mature ones, new research indicates. The findings appear in the Feb. 6 issue of The Journal of Neuroscience. The work significantly advances scientific understanding of when and how fear is stored and unlearned, and introduces new thinking on the implications of fear experience early in life.

Compelled to mate, yet firmly attached to the rock, barnacles have evolved the longest penis of any animal for their size - up to 8 times their body length - so they can find and fertilize distant neighbours.

A burger and fries may be the quintessential North American meal but it can also be viewed as the perfect example of humanity’s increasingly varied diet, according to researchers who have conducted a unique study of the plants used around the world for food.

Measles epidemics in Niger fluctuate wildly from one season to another but the timing of the outbreaks always coincides with the end of the annual rainy season, according to an international team of researchers.

Chemical peels using either alpha-hydroxy acid or beta-hydroxy acid are both highly effective in treating mild to moderately severe facial acne, researchers at the Saint Louis University School of Medicine have found – the first study to compare the two different types of acid peels as therapies for the skin disorder.

The study was published online February 5 in the February 2008 edition (Volume 6, Issue 2) of the journal PLoS Biology.

Did modern birds originate around the time of the dinosaurs' demise, or have they been around far longer?

Two novel proteins studied by a University at Buffalo professor of microbiology and immunology appear to have the potential to enhance the production of antibodies against a multitude of infectious agents.

Researchers at the University of Pennsylvania School of Medicine have discovered that introns, or junk DNA to some, associated with RNA are an important molecular guide to making nerve-cell electrical channels. Senior author James Eberwine, PhD, Elmer Bobst Professor of Pharmacology, and lead authors Kevin Miyashiro, and Thomas J. Bell, PhD, both in Eberwine’s lab, report their findings in this week's early online edition of the Proceedings of the National Academy of Sciences.
