People who overuse barbiturates and opioids, such as codeine, butalbital, and oxycodone, to treat migraine are at an increased risk of developing chronic migraine, according to new research.

A consortium of scientists has discovered new non-histone targets for one enzyme previously believed to modify only histones -- the group of proteins that creates tightly bundled packages of DNA strands.

A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a 3-D view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears in the journal Nature Neuroscience.

Nitric oxide has emerged as an important signaling molecule in plants -- as in mammals, including people. In studies of a tropical medicinal herb as a model plant, researchers have found that nitric oxide targets a number of proteins and enzymes in plants.

New results on genetic techniques that are helping doctors diagnose and treat lung cancer have just been released. A new test helps make crucial distinctions between types of lung cancer. The researchers show the method can accurately distinguish between squamous and non-squamous forms of non-small-cell lung cancer based on the levels of different microRNA molecules found in tissue samples.
