Rockville, MD (June 1, 2020) - Each year, thousands of pounds of food are wasted and billions of dollars in food sales lost because of recalls tied to foodborne infections. Using a newly developed approach, researchers identified seasonal peaks for foodborne infections that could be used to optimize the timing and location of food inspections.
A new analysis of more than 200,000 people found that eating high-quality carbohydrates, such as whole grains, was associated with a lower risk for type 2 diabetes.
"High intake of carbohydrates has been suggested to be associated with a higher risk of type 2 diabetes," said research team leader Kim Braun, PhD, from Erasmus University Medical Center and
Harvard T.H. Chan School of Public Health. "We looked at whether this effect is different for high-quality carbohydrates and low-quality carbohydrates, which include refined grains, sugary foods and potatoes."
Rockville, MD (June 1, 2020) - Results from a new study suggest that college men who play video games tend to exercise less and have poorer eating habits compared to non-gamers. Nearly 70 percent of men included in the study reported playing at least some video games.
Rockville, MD (June 1, 2020) - A new study of children and teens found that more than 25% of the calories they consume were considered empty - those from added sugars and solid fats. The top sources of these empty calories were soft drinks, fruit drinks, cookies and brownies, pizza, and ice cream.
What The Study Did: Anxiety, depression, mood and fear of workplace violence were assessed in a group of young physicians in China before and during the COVID-19 outbreak.
Authors: Weidong Li, M.D., Ph.D., of Shanghai Jiao Tong University in Shanghai, China, and Srijan Sen, M.D., Ph.D., of the University of Michigan in Ann Arbor, are the corresponding authors.

They worked in hospitals hundreds of miles from the epicenter of COVID-19. Their city of 24 million people locked down hard enough, and did enough testing, that it only had a few hundred cases of the disease.
But hundreds of young Chinese doctors in a new study still experienced a sharp drop in mood, a rise in depression and anxiety symptoms, and a doubling of their fear of workplace violence, in just the first month of the coronavirus pandemic.
While recent advances in ancient DNA analysis have established the major patterns of prehistoric human migration in western Eurasia, the population history of eastern Eurasia remains little understood. Northern China is of particular importance, as it harboured two of the world's earliest agricultural centres for millet farming: the Yellow and West Liao River basins. Both basins are famous for their rich archaeological cultures and their influence on nearby regions.
The halo that surrounds our own Milky Way galaxy is much hotter than scientists once believed - and it may not be unique among galaxies.
The new findings were presented at the annual meeting of the American Astronomical Society, held online this week because of the COVID-19 pandemic.
In previous work, researchers at The Ohio State University found that parts of the Milky Way's halo - the hazy fog of dust, gas and dark matter that surrounds some galaxies - was at least 10 times hotter than anyone had known before.
Nearly a century after insulin was discovered, an international team of researchers including University of Utah Health scientists report that they have developed the world's smallest, fully functional version of the hormone, one that combines the potency of human insulin with the fast-acting potential of a venom insulin produced by predatory cone snails. The finding, based on animal studies, could jumpstart the development of insulin treatments capable of improving the lives of those with diabetes.
CAMBRIDGE, MA -- Inspired by the Japanese art of paper cutting, MIT engineers have designed a friction-boosting material that could be used to coat the bottom of your shoes, giving them a stronger grip on ice and other slippery surfaces.
The researchers drew on kirigami, a variation of origami that involves cutting paper as well as folding it, to create the new coating. Laboratory tests showed that when people wearing kirigami-coated shoes walked on an icy surface, they generated more friction than the uncoated shoes.
Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are these stars plagued by magnetic spots, some also experience superflare events, explosions of energy several million times more energetic than similar eruptions on the Sun. The findings, published today in Nature Astronomy, help astronomers better understand these puzzling stars and open doors to resolving other elusive mysteries of stellar astronomy.
We are free to wander but usually when we go somewhere it's for a reason. In a new study, researchers at The Picower Institute for Learning and Memory show that as we pursue life's prizes a region of the brain tracks our location with an especially strong predilection for the location of the reward. This pragmatic bias of the lateral septum suggests it's a linchpin in formulating goal-directed behavior.
Maunakea, Hawaii - Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii and old X-ray data from NASA's Chandra X-ray Observatory to unlock a mystery surrounding a bright, lensed, heavily obscured quasar.
Ben-Gurion University Researchers Control Cattle Microbiomes to Produce Less Methane and Reduce Greenhouse Gases
BEER-SHEVA, Israel, June 1, 2020 - Ben-Gurion University of the Negev (BGU) researchers have learned to control the microbiome of cattle for the first time which could inhibit their methane production, and therefore reduce a major source of greenhouse gasses.
Major climate changes leading to great fluctuations in sea levels took place during the Quaternary period 2.58 million years ago. The sea receded during the glaciations, because the water ended up stored in huge ice masses; when the ice melted, the sea levels rose. So "in this work we analysed the rocky undersea coastal platforms formed throughout the period: the situation of all these terraces, their morphology, etc.
