A study by the University of Liverpool has found that the genetic diversity of wild plant species could be altered rapidly by anthropogenic climate change.

Every organism--from a seedling to a president--must protect its DNA at all costs, but precisely how a cell distinguishes between damage to its own DNA and the foreign DNA of an invading virus has remained a mystery.

Researchers led by the UCLA Fielding School of Public Health examined HIV testing trends among adults ages 50 through 64 both before and after 2006, when the Centers for Disease Control and Prevention (CDC) recommended that most doctors automatically screen all patients for HIV regardless of whether they have symptoms.

Dr. Anita Göndör and her colleagues at Karolinska Institutet show that circadian genes 'take a nap' everyday at the periphery of the nucleus. Mobility between different physical environments in the cell nucleus regulates the daily oscillations in the activity of genes that are controlled by the internal biological clock, according to a study that is published in the journal Molecular Cell. Eventually, these findings may lead to novel therapeutic strategies for the treatment of diseases linked with disrupted circadian rhythm.

Researchers from the Gladstone Institutes have revealed that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another.

Florida State University researchers have taken a big step forward in the fight against cancer with a discovery that could open up the door for new research and treatment options.

Degenerating neurons in patients with Alzheimer's disease (AD) measurably responded to an experimental gene therapy in which nerve growth factor (NGF) was injected into their brains, report researchers at University of California, San Diego School of Medicine in the current issue of JAMA Neurology.
