New study offers a closer look at the association between childhood sleep-disordered breathing, including snoring and sleep apnea, and behavioral problems like hyperactivity and anxiety. Children with sleep-disordered breathing who are also overweight, sleep for short periods of time, or have another sleep disorder like insomnia are more likely to have behavior issues.

Researchers have discovered a gene in flies whose activity rises and falls depending upon the amount of protein and sugar in the insects' diets. The findings might shed light on the way the insects' bodies -- and perhaps those of humans too -- handle dietary extremes.

The ability of brain cells to communicate and to take in substances from their surface is essential to the production of a key ingredient in Alzheimer's brain plaques, neuroscientists have learned.

Marijuana is among the most frequently used illicit drugs by women during their childbearing years and there is growing concern that marijuana abuse during pregnancy, either alone or in combination with other drugs, may have serious effects on fetal brain development. There is strong evidence that THC, the main psychoactive component of marijuana, crosses the placenta, that maternal marijuana abuse results in intrauterine growth retardation and that infants exposed to marijuana exhibit a temporary syndrome that includes lethargy and decreased muscle tone.

New data have characterized a molecular pathway underlying low-grade forms of a type of brain tumor known as an astrocytoma. The authors therefore suggest that therapeutics targeting this pathway might provide a new approach to treating individuals with low-grade atrocytomas.

A new study reveals that omega-3 intake during the last months of pregnancy boosts an infant's sensory, cognitive, and motor development. However, high concentration of omega-3s in mother's milk doesn't seem to have the same positive effect in breast-fed babies, highlighting the importance of prenatal exposure to omega-3 fatty acids.

Researchers report the discovery of a critical early player in the path that turns cells to fat. Given that obesity is a major health concern, such a fuller understanding of the molecular processes governing fat tissue formation could ultimately hold clinical importance.

Researchers have identified a key mechanism by which the protein sludge that kills brain cells accumulates in Alzheimer's disease. Their findings in mice offer clues to treating AD and also could explain why memory centers of the brain are most affected in the disease.

A team has solved important puzzles concerning how certain proteins guide the reproduction of bacteria. Solving the Z ring's mysteries may lead to new antibiotics.

With a bit of genetic trickery, researchers have turned normal skin cells into cancer stem cells, a step that will make these naturally rare cells easier to study.
