Researchers have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at some times of the day instead of others.

Scientists investigating the effects of cannabis on bone health have found that its impact varies dramatically with age.

Researchers have determined that Candida albicans, a human fungal pathogen, pursues both same-sex and the more conventional opposite-sex mating.

Scientists have found that a protein that can cause scarring of fat tissue could be key to understanding the link between obesity and type 2 diabetes.

At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from. Did our ancestors come from Europe or Asia? As curious as we are about our ancestors, for practical purposes, we need to think about the ancestry of our genes, according to one anthropologist, who says our genetic ancestry influences the genetic traits that predispose us to risk or resistance to disease.

New research indicates that decreased cravings for pleasure may be at the root of a core symptom of major depressive disorder. The research is in contrast to the long-held notion that those suffering from depression lack the ability to enjoy rewards, rather than the desire to seek them.

We see, hear and feel, and make sense of countless diverse, quickly changing stimuli in our environment seemingly without effort. However, doing what our brains do with ease is often an impossible task for computers.

Scientists have made an important advance in understanding the biological processes involved when cells are prompted to die. The work may help scientists to eventually develop new treatments for the many common diseases and conditions which occur when cell death goes wrong.

Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems

Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. New research findings from Sweden and China open up the possibility of a new and effective treatment that can be started as late as two days after birth.
