An auditory illusion thought to synchronize brain waves and alter mood is no more effective than other sounds, according to research in adults recently published in eNeuro. The effect reported in other studies might be a placebo but could still have helpful effects for some people.
TAMPA, Fla. (Feb. 17, 2020) -- The protein β-arrestin-2 increases the accumulation of neurotoxic tau tangles, a cause several forms of dementia, by interfering with removal of excess tau from the brain, a new study by the University of South Florida Health (USF Health) Morsani College of Medicine found.
Information on what our ancestors ate is based mainly on carbon and nitrogen isotope analyses of the structural protein collagen in bones and dentin. Nitrogen isotope analysis, in particular, helps scientists determine whether animal or plant food was consumed. Since collagen, like proteins in general, is not easily conservable, this method cannot be used to examine vertebrate fossils older than about 100,000 years.
First study to map atomic structure of a key enzyme complex in paramyxoviruses, a family of RNA viruses
Enzyme is responsible for assembling RNA molecules, providing a target for new antiviral drugs
Although from a different family, coronavirus functions similarly
Researchers used cryo-EM, a revolutionary technique that gives a clear view of proteins
AMHERST, Mass. - Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate change and in the future of medicine.
While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology.
The discovery, published today in Nature Energy, overcomes the issue faced by high-powered, fast-charging supercapacitors - that they usually cannot hold a large amount of energy in a small space.
Scientists at the MDC have discovered stem cells responsible for the most common form of kidney cancer. The team of Walter Birchmeier has found a way to block the growth of these tumors in three models of the disease.
Not all cancer cells are equal. Tumors contain potent cancer stem cells which produce metastases and can regenerate the disease if they escape a treatment. This makes them vital targets for therapies - if scientists can isolate them and probe their weaknesses. But the cells are often so rare that for many types of cancer, they have yet to be found.
The most recent guidelines for primary prevention recommend aspirin use for individuals ages 40 to 70 years who are at higher risk of a first cardiovascular event, but not for those over 70. Yet, people over 70 are at increasingly higher risks of cardiovascular events than those under 70. There has been considerable confusion from recently reported results of three large-scale randomized trials of aspirin in high risk primary prevention subjects, one of which showed a significant result, but the other two, based possibly on poor adherence and follow up, did not.
People who rely on social media for information were more likely to be misinformed about vaccines than those who rely on traditional media, according to a study of vaccine knowledge and media use by researchers at the Annenberg Public Policy Center of the University of Pennsylvania.
ANN ARBOR, Mich. -- Parents from lower-income families are less likely to describe their home tap water as safe, say their water has been tested or feel confident in the quality of drinking fountain water at their child's school compared with higher income peers, a new national poll suggests.
