A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
Scientists have discovered a group of brain cells that may play a role in keeping smokers addicted to nicotine. Their work could ultimately lead to new drugs to help people conquer their tobacco dependence.
A protein transferred from male to female mosquitoes during sex influences female mating behavior—a phenomenon that could be exploited to limit the spread of mosquito-borne illnesses like Zika and dengue.
Researchers have found that the cells directing the very first steps of brain formation are not other neurons, as scientists have long assumed. They've also uncovered previously hidden molecular pathways that attract neurons into the brain.
Scientists found that inhibiting a regulatory protein alters the intricate signaling chemistry that is responsible for many of the disease’s symptoms. The findings provide a path to possible therapeutics for disorders associated with Fragile X.
