COLUMBUS, Ohio - More Americans than not believe that college athletes should be allowed to be paid more than what it costs them to go to school, a new national study of nearly 4,000 people suggests.
Findings from the National Sports and Society Survey (NSASS), led by researchers at The Ohio State University, suggest that 51 percent of adults agree that college athletes should have the ability to be paid above school costs, 41 percent disagree and 8 percent don't know.
Scientists studying the complex relationship between aging and memory have found that in a controlled experiment, people can remember the details about past events with a surprising 94% accuracy, even accounting for age. These results, published in the journal Psychological Science, suggest that the stories we tell about past events are accurate, although details tend to fade with time.
CHAMPAIGN, Ill. -- The brains of healthy adults recovered faster from a mild vascular challenge and performed better on complex tests if the participants consumed cocoa flavanols beforehand, researchers report in the journal Scientific Reports. In the study, 14 of 18 participants saw these improvements after ingesting the flavanols.
The images reveal that vibrational strong coupling can be achieved, which is a phenomenon that recently attracts wide attention for its potential use to control fundamental physical and chemical material properties. The result could lead the development of a novel platform for on-chip chemical identification of tiny amounts of molecules and for studying fundamental aspects of strong coupling phenomena on the nanometer scale. The work has been published in Nature Photonics (DOI: 10.1038/s41566-020-00725-3).
Protocell compartments used as models for an important step in the early evolution of life on Earth can be made from short polymers. The short polymers, which better approximate the likely size of molecules available on the early Earth, form the compartments through liquid-liquid phase separation in the same manner as longer polymers. Although they have no membrane separating them from their environment, the protocells can sequester RNA and maintain distinct internal microenvironments, in some ways even outperforming similar compartments made from longer polymers.
Boston - Results of a new study show that opioid overdose deaths involving more than one substance (polysubstances) are more common than opioid-only overdose deaths among youth. Led by researchers at Boston Medical Center's Grayken Center for Addiction, the data shows that cocaine and other stimulants like crystal methamphetamine are the substances most commonly involved in opioid overdose deaths in young people between the ages of 13 and 25.
Proteins are the essential substrate of learning and memory. However, while memories can last a life-time, proteins are relatively short-lived molecules that need to be replenished every couple of days. This poses a huge logistic challenge on over 85 billion neurons in the brain: billions of proteins need to be continuously produced, shipped, addressed and installed at the right location in the cell. Scientists at the Max Planck Institute for Brain Research have now addressed a bottleneck in the protein trafficking system, dendritic branch points.
American alligators are about as close to dinosaurs as you can get in modern times, and can grow up to 14 feet in length. While much smaller reptiles such as lizards are able to regenerate their tails, the question of whether the much larger alligator is able to regrow their massive tails has not been well studied. A team of researchers from Arizona State University and the Louisiana Department of Wildlife and Fisheries have uncovered that young alligators have the ability to regrow their tails up to three-quarters of a foot, or 18% of their total body length.
Sexual minorities, especially women, who misuse substances more likely to have psychiatric disorders
MIAMI--The United Nations recently released a new report projecting future coral reef bleaching globally. The lead author of the report, Ruben van Hooidonk, is a scientist with NOAA's Cooperative Institute of Marine and Atmospheric Studies based at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science.
Results highlights from the report include:
How much information can you get from a speck of purple pigment, no bigger than the diameter of a hair, plucked from an Egyptian portrait that's nearly 2,000 years old? Plenty, according to a new study. Analysis of that speck can teach us about how the pigment was made, what it's made of--and maybe even a little about the people who made it. The study is published in the International Journal of Ceramic Engineering and Science.
The genetic code of the SARS-CoV2 virus is exactly 29,902 characters long, strung through a long RNA molecule. It contains the information for the production of 27 proteins. This is not much compared to the possible 40,000 kinds of protein that a human cell can produce. Viruses, however, use the metabolic processes of their host cells to multiply. Crucial to this strategy is that viruses can precisely control the synthesis of their own proteins.
Scientists have revealed that plants have a 'sealing' mechanism supported by microbes in the root that are vital for the intake of nutrients for survival and growth.
Washington, DC, November 19, 2020 - The COVID-19 pandemic has necessitated widespread social isolation, affecting all ages of global society.
Rochester Institute of Technology students discovered lost text on 15th-century manuscript leaves using an imaging system they developed as freshmen. By using ultraviolet-fluorescence imaging, the students revealed that a manuscript leaf held in RIT's Cary Graphic Arts Collection was actually a palimpsest, a manuscript on parchment with multiple layers of writing.
