For the first time, scientists have revealed a mechanism underlying the cellular degeneration of upper motor neurons, a small group of neurons in the brain recently shown to play a major role in ALS pathology.
The skull dates from around 55,000 years ago, fitting into the period when scientists had thought the migrants inhabited the area.
Evidence is rapidly growing showing vital relationships between both diet quality and potential nutritional deficiencies and mental health, a new international collaboration led by the University of Melbourne and Deakin University has revealed.
Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein called Glucagen-like peptide 1 (GLP-1).
The Food and Drug Administration (FDA) has approved for evaluating in people a nanoparticle-based imaging agent jointly developed at Washington University School of Medicine in St. Louis and the University of California, Santa Barbara, in collaboration with Texas A&M University.
Cells are incredibly complicated machines with thousands of interacting parts — and disruptions to any of those interactions can cause disease.
Killer T cells are one of the body's main lines of defense against pathogens.
Tuberculosis affects over 12 million people globally, and is usually treated with a course of four drugs over several months.
Scientists have determined how an enzyme essential for energy metabolism functions.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
The World Health Organization has proposed reforms that could overhaul its structure after botching the response to the biggest-ever Ebola outbreak.
A top U.N. official in the fight against Ebola greeted just three patients at one treatment center he visited this week in Sierra Leone.
Scientists have long known that sleep, memory and learning are deeply connected. Most animals, from flies to humans, have trouble remembering when sleep deprived, and studies have shown that sleep is critical in converting short-term into long-term memory, a process known as memory consolidation.
A team of scientists based at Brown University has found that reducing expression of a fundamentally important gene called Myc significantly increased the healthy lifespan of laboratory mice, the first such finding regarding this gene in a mammalian species.
A new procedure can quickly and efficiently increase the length of human telomeres, the protective caps on the ends of chromosomes that are linked to aging and disease.
Eerie fluorescent blue patches of water glimmering off Hong Kong's seashore are magnificent, disturbing and potentially toxic.
Children under two years old can learn certain communication skills from a video.
It involves fostering a community of "good" gut bacteria.
A miniscule cluster of estrogen-producing nerve cells in the mouse brain exerts highly specific effects on aggressive behavior in both males and females.
An Arizona hospital is testing medicines very early in development and never tried on brain tumors before.
The President briefly mentioned the project during the State of The Union earlier this week.
Standards proposed by the Agriculture Department aim to reduce rates of salmonella and campylobacter, another pathogen that can cause symptoms similar to salmonella, in chicken parts, ground chicken and ground turkey. The standards would be voluntary but designed to pressure companies to take steps to reduce contamination.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have produced an approach that protects animal models against a type of genetic disruption that causes intellectual disability, including serious memory impairments and altered anxiety levels.
Neonatal intestinal disorders that prevent infants from getting the nutrients they need may be caused by defects in the lysosomal system that occur before weaning, according to a new Northwestern Medicine study.
Seventy people have been infected in a measles outbreak that led California public health officials to urge those who haven't been vaccinated against the disease, including children too young to be immunized, should avoid Disney parks where the spread originated.
