New research finds new link between these biological clocks and lung disease.

Ethanol-producing Zymomonas mobilis can live on nitrogen gas, potentially cutting costs and environmental waste in biofuel production.

A researcher at Missouri University of Science and Technology has discovered a bacterium that can produce hydrogen, an element that one day could lessen the world’s dependence on oil.

The health-promoting perks of wine have attracted the spotlight recently, leaving beer in the shadows. But scientists are discovering new ways in which the latter could be a more healthful beverage than once thought.

Linsey Marr, a professor in the Charles E. Via Jr. Department of Civil and Environmental Engineering at Virginia Tech, is obsessed with flu transmission.

Stanford University announced Jan. 29 that it has received a grant from the Bill & Melinda Gates Foundation to accelerate efforts in vaccine development. The $50 million grant over 10 years will build on existing technology developed at Stanford and housed in the Human Immune Monitoring Core, and will establish the Stanford Human Systems Immunology Center. The center aims to better understand how the immune system can be harnessed to develop vaccines for the world's most deadly infectious diseases.

Salk scientists discover how a "mini-brain" in the spinal cord aids in balance.

New study says some is sitting on the Gulf floor.

Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to researchers at the University of Illinois at Chicago.

For the first time, UNC neuroscientist Garret Stuber, PhD, imaged activity patterns of individual brain cells in freely moving mice to link specific basic behaviors to particular neurons.

In a new study, Sanford-Burnham Medical Research Institute researchers have used human pluripotent stem cells to generate new hair. The study represents the first step toward the development of a cell-based treatment for people with hair loss. In the United States alone, more than 40 million men and 21 million women are affected by hair loss. The research was published online in PLOS ONE.

Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. Scientists have known about the presence of ribonucleotides in DNA, but until now had not been able to determine exactly what they are and where they are located in the DNA sequences.
