RNA-associated introns guide nerve-cell channel production

Researchers at the University of Pennsylvania School of Medicine have discovered that introns, or junk DNA to some, associated with RNA are an important molecular guide to making nerve-cell electrical channels.

Predisposition for obesity might be wired into the brain

A predisposition for obesity might be wired into the brain from the start, suggests a new study of rats in the February issue of Cell Metabolism, a publication of Cell Press.

MIT applies engineering approach to studying biological pathways

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.

Video games activate reward regions of brain in men more than women

Allan Reiss, MD, and his colleagues have a pretty good idea why your husband or boyfriend can't put down the Halo 3. In a first-of-its-kind imaging study, the Stanford University School of Medicine researchers have shown that the part of the brain that generates rewarding feelings is more activated in men than women during video-game play.

Huntington's disease problem starts early

The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron.

Blocking parasites' communication reduces infection

One of the most common human parasites, Toxoplasma gondii, uses a hormone lifted from the plant world to decide when to increase its numbers and when to remain dormant, researchers at Washington University School of Medicine in St. Louis have found.

New understanding on the mechanics of gene transcription

The molecular machinery behind gene transcription -- the intricate transfer of information from a segment of DNA to a corresponding strand of messenger RNA -- isn't stationed in special "transcription factories" within a cell nucleus, according to Cornell researchers.

Researchers trigger insulin production in diabetic mice

If the human body were a stage, then proteins would rank among the lead actors in the play we call "Life."

New understanding of cell's inner workings

A group of scientists in Princeton's Department of Ecology and Evolutionary Biology has uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings.

Two genes are important key to regulating immune response

A research team at Weill Cornell Medical College in New York City has identified two genes that may be crucial to the production of an immune system cytokine called interleukin-10 (IL-10)

What makes us shiver?

Researchers at Oregon Health & Science University's Neurological Sciences Institute have uncovered the system that tells the body when to perform one of its most basic defenses against the cold: shivering.

New drug that cuts risk of cardiovascular disease shows promise

The first clinical trial of a new kind of drug to cut the risk of cardiovascular disease has been found safe and effective at dropping levels of "bad" low density lipoprotein (LDL) cholesterol by as much as 40 percent.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.
