For young male offspring who suffer a dominant mother, a brother may be on the way to help bear the burden. And all because of follicular testosterone. A growing body of evidence suggests a maternal influence on sex determination: dominant human females conceive more sons.

They may never win an Oscar, but scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now.

The rapid growth of China’s industrial and transportation infrastructure is helping to establish non-native species throughout that country and “setting the stage for potentially rampant environmental damage,” according to an article in the April 2008 issue of BioScience.

Molecular biologists at the University of California, San Diego have found one piece of the complex puzzle of autophagy, the process of “self-eating” performed by all eukaryotic cells -- cells with a nucleus -- to keep themselves healthy.

Despite the significance of taste to both human gratification and survival, a basic understanding of this primal sense is still unfolding.

Twenty-six winners from schools throughout Oxfordshire received prizes at the Sixth Form Biologist of 2007-08 ceremony held at the Oxford University Museum of Natural History on 7 February.

An MIT team has used an engineering approach to show that complex biological systems can be studied with simple models developed by measuring what goes into and out of the system.

Zebrafish are genetically similar to humans and are good models for human biology and disease. Now, researchers at Children's Hospital Boston have created a zebrafish that is transparent throughout its life.

In the January 18th issue of Molecular Cell, Case Western Reserve University School of Medicine researcher Kristian E. Baker, Ph.D. challenges molecular biology’s established body of evidence and widely-accepted model for nonsense-mediated messenger ribonucleic acid (mRNA) decay.

New research at the University of Chicago finds evidence for a clever way that people manage to alleviate the pain of loneliness: They create people in their surroundings to keep them company.

Biologists have created baker’s yeast capable of living to 800 in yeast years without apparent side effects.

Humans may not be any more sensitive in detecting biological motion compared with nonbiological motion, concludes a study recently published in Journal of Vision, an online, free-access publication of the Association for Research in Vision and Ophthalmology (ARVO).
