Declining life expectancies in the US include Gen X and Y Americans, in addition to the older Baby Boomers. But the causes of premature mortality vary by race, gender and ethnicity, according to a new study. The research...

A study sheds new light on how the hallmarks of Alzheimer's disease -- amyloid-beta plaques and neurofibrillary tangles containing the protein tau -- produce their damaging effects in the brain.

Acrolein, a molecule implicated as a metabolic waste product, could be a potential biomarker for multiple sclerosis, researchers report.

Scientists have determined the conditions under which it becomes easier for sac to pass through biological membranes and potentially deliver molecules attached to these them at specific locations.

What happens in the brain of a compulsive drug user? Neurobiologists have discovered that the brain circuit connecting the decision-making region to the reward system is stronger in compulsive animals. The researchers al...

Proteins designed in the lab can now zip together in much the same way that DNA molecules zip up to form a double helix. The technique could enable the design of protein nanomachines that can potentially help diagnose an...

Scientists have developed a new vaccine against the Zika virus. This vaccine should prevent the virus from causing microcephaly and other serious conditions in unborn babies.

If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organization of the cerebral cortex and on memory. Researchers demonstrated that, in the months after...

In speech and music, words and notes depend on each other. Humans are highly sensitive to such dependencies, but the evolutionary origins of this capacity are poorly understood. Cognitive biologists have conducted playba...

A recent study shows how a novel regulatory mechanism serves as an important biomarker for the development of diabetes, as well as a potential therapeutic target for its prevention.

In five-year-old children, the risk for overweight is almost twice as high if they at 12 months had consumed milk cereal drinks every day, a study in the journal Acta Paediatrica shows.

Researchers have found that young adults who experienced repetitive mild traumatic brain injury (mTBI), or concussions, can experience persistent cognitive changes as well as altered brain activity.

This bad habit could raise your risk of serious eye infections and even lead to vision loss.

Physicists from Skoltech have invented a new method for calculating the dynamics of large quantum systems. Underpinned by a combination of quantum and classical modeling, the method has been successfully applied to nucle...

Study reveals PRRX1 gene expression results in cell cycle arrest and quiescence of oligodendrocyte progenitors, blocking myelin production.

Data breaches, hacked systems and hostage malware are frequently topics of evening news casts--including stories of department store, hospital, government and bank data leaking into unsavory hands--but now a team of engi...

Researchers have identified how alcohol influences dopaminergic and inhibitory neurons in the ventral tegmental area. The findings could help develop new treatments for alcohol dependence.

Researchers, using eye tracking software, report what we look at helps guide our decisions when faced with two visible choices.

Children that are exposed to multiple cats and dogs in their first year of life go on to have lower rates of asthma, hay fever and eczema later in life
