By discovering how certain viruses use their host cells to replicate, microbiologists have identified a new approach to the development of universal treatments for viral illnesses such as meningitis, encephalitis, hepatitis and possibly the common cold.

The radula sounds like something from a horror movie -- a conveyor belt lined with hundreds of rows of interlocking teeth. In fact, radulas are found in the mouths of most molluscs, from the giant squid to the garden snail. Now, a "prototype" radula found in 500-million-year-old fossils shows that the earliest radula was not a flesh-rasping terror, but a tool for humbly scooping food from the muddy sea floor.

Researchers, doctors and patients tend to agree that during the high-risk period after an attempted suicide, the treatment of choice is close contact, follow-up and personal interaction in order to prevent a tragic repeat. Now, however, new research shows that this strategy does not work.

Animals that literally have holes in their brains can go on to behave as normal adults if they've had the benefit of a little cognitive training in adolescence. That's according to new work featuring an animal model of schizophrenia, where rats with particular neonatal brain injuries develop schizophrenia-like symptoms.

Same effect in half the time: Researchers have shown that 30 minutes of daily training provide an equally effective loss of weight and body mass as 60 minutes.

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our closest relative. These genes' identification could improve understanding of human brain diseases like autism and schizophrenia, as well as learning disorders and addictions.

Almost 30 years after discovery of a link between alcohol consumption and certain forms of cancer, scientists are reporting the first evidence from research on people explaining how the popular beverage may be carcinogenic. The results have special implications for hundreds of millions of people of Asian descent.

Skeletal muscle degeneration in Duchenne muscular dystrophy (DMD) is worsened by stiffening of the microtubule cytoskeleton that provide structure inside muscle cells.

Preemptive cognitive training —- an early intervention to address neuropsychiatric deficiencies —- can help the brain function normally later in life, a team of researchers has found through a series of experiments on laboratory rats. Their findings hold promise for addressing a range of brain impairments in humans, including schizophrenia.

A research group is studying disease resistance in tuberculosis. The group has described the structure of a regulator that controls the expression of a pump that removes toxins from the bacteria.
