Non-pharmaceutical interventions such as voluntary shelter-in-place, quarantines, and other steps taken to control the SARS-CoV-2 virus can reduce the peak number of infections, daily infection rates, cumulative infections, and overall deaths, a new study published in the journal PLOS ONE has found.
Despite guidelines plastered on the walls and floors of grocery and retail stores encouraging customers to maintain six-feet of physical distance during the pandemic, many do not. A new study by researchers at the Conrad N. Hilton College of Hotel and Restaurant Management identifies two key messaging components that could improve the persuasiveness of those appeals and trigger compliance.
The "mismatch hypothesis" argues that our bodies evolved to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. This intuitive idea is hard to test directly, but the Turkana, a pastoralist population in remote Kenya, present a natural experiment: genetically homogenous populations whose diets stretch across a lifestyle gradient from relatively "matched" to extremely "mismatched" with their recent evolutionary history.
The time has come for reform on how the United States deals with the electoral process, the environment and social justice, according to a new national poll released today by the UMass Lowell Center for Public Opinion that takes an in-depth look at the views of Americans age 18 to 39.
Researcher makes 'little data' act big through, the application of mathematical techniques normally used for time-series, to spatial processes. The study, 'An information-theoretic approach to study spatial dependencies in small datasets,' featured on the cover of Proceedings of the Royal Society.
Study by Brazilian and South African researchers is the first to prove, using a graph analysis tool, that REM dream narratives tend to be more complex and connected than reports of non-REM dreams.
The Gerontological Society of America's highly cited, peer-reviewed journals are continuing to publish scientific articles on COVID-19. The following were published between October 8 and 21; all are free to access:
Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.
According to the Mayo Clinic, about 15% of couples are infertile, and male infertility plays a role in over one-third of these cases. Often, problems with sperm development are to blame. Now, researchers reporting in ACS Nano have found a way to deliver a protein important for sperm cell production directly to mouse testicles, where it restored normal sperm development and allowed previously infertile mice to father pups.
Bronze Age pastoralists in what is now southern Russia apparently covered shorter distances than previously thought. It is believed that the Indo-European languages may have originated from this region, and these findings raise new questions about how technical and agricultural innovations spread to Europe. An international research team, with the participation of the University of Basel, has published a paper on this topic.
