Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.

A groundbreaking study of popularity by a Michigan State University scientist has found that genes elicit not only specific behaviors but also the social consequences of those behaviors.

A new University of Illinois study suggests that we may pay a price for ingesting too much fructose. According to lead author Manabu Nakamura, dietary fructose affects a wide range of genes in the liver that had not previously been identified.

In a study in the advance online publication of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine of Yeshiva University describe a technique for looking more precisely at a fundamental step of a cell's life — a gene, DNA, being read into a message, mRNA. The technique could provide a window into the process by which genes are switched on inappropriately, causing disease.

When mice that lack steroid receptor-2 (SRC-2) – a master regulator gene called a coactivator – fast for a day, their blood sugar levels plummet. If they go another day without food, they will die.

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age.

There is no greater sacrifice than giving one's life for others, and a new study by Rice University biologists and Baylor College of Medicine (BCM) geneticists is helping narrow the search for genes that drive single-celled amoebae to stick close to their kin before altruistically giving their all.

Neuroscientists at the Indiana University School of Medicine have created the first comprehensive map of genes likely to be involved in bipolar disorder, according to research published online Nov. 21 in the American Journal of Medical Genetics.

Only 2 genes make the difference between herbaceous plants and trees

Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.

New research, just published by researchers from the University of Georgia, provides the first evidence that a key gene may be crucial to maintaining the production of the thymus and its disease-fighting T-cells after an animal’s birth.

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.
