Cortex maturation in attention deficit hyperactivity disorder

In youth with attention deficit hyperactivity disorder (ADHD), the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, an imaging study by researchers at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has revealed.

Plants provide better understanding of the epidemiology and evolution of infectious disease

Animals, like plants, can build tolerance to infections at a genetic level, and these findings could provide a better understanding of the epidemiology and evolution of infectious disease, according to evolutionary biologists.

Overeating alters the core mechanism of the body clock

Our body's 24-hour internal clock, or circadian clock, regulates the time we go to sleep, wake up and become hungry as well as the daily rhythms of many metabolic functions.

Newly completed genome sequence may provide new treatment options for dandruff

Scientists from P&G Beauty announced that they successfully sequenced the complete genome for Malassezia globosa (M. globosa) , a naturally occurring fungus responsible for the onset of dandruff and other skin conditions in humans.

Research reveals critical knowledge about the nervous system

Uncover the neural communication links involved in myelination, the process of protecting a nerve's axon, and it may become possible to reverse the breakdown of the nervous system's electrical transmissions in such disorders as multiple sclerosis, spinal cord injuries, diabetes and cancers of the nervous system.

Brain chemistry and genes dictate nicotine cravings

Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night, University of Colorado at Boulder researchers say.

EU project confirms Europe's excellence in migraine research

An EU-funded project on migraines has not only taken researchers a step closer to understanding the causes of these incapacitating attacks, but has created a critical mass, reinforcing Europe's reputation of excellence in this field, and reassuring migraine sufferers that their condition is being taken seriously.

Genes play important role in risk for dependence on illicit and licit drugs

The genes that play a role in illegal drug abuse are not entirely the same as those involved in dependence on legal substances like alcohol and nicotine, and caffeine addiction appears to be genetically independent of all the others, according to a study led by Virginia Commonwealth University researchers.

FADS2 gene governs IQ boost from breastfeeding

The known association between breast feeding and slightly higher IQ in children has been shown to relate to a particular gene in the babies, according to a report this week in the Proceedings of the National Academy of Sciences.

Breastfeeding boosts infants' IQs, but only if the babies have a specific genetic variant

This study looked at how long-chain polyunsaturated fatty acids (LC-PUFAS), which are present in human milk but not in cow's milk or most infant formulas, are metabolized. LC-PUFAS in breast milk, the authors said, is believed to enhance cognitive development because the fatty acids are required for efficient neurotransmission and are involved in neuronal growth and regeneration.
