The COVID-19 pandemic and resulting economic shutdowns have severely disrupted and spotlighted weaknesses in the U.S. food system. Farmers, food distributors and government agencies are working to reconfigure supply chains so that food can get to where it’s needed.

AUSTIN, Texas -- When the novel coronavirus began spreading during the early months of 2020, it put kinks in multinational production chains -- first in China and then around the globe. But it didn't have to happen that way, according to Francisco Polidoro, associate management professor at the McCombs School of Business at The University of Texas at Austin.
The international First-line Radiosurgery for Small-Cell Lung Cancer (FIRE-SCLC) analysis led by University of Colorado Cancer Center researchers and published today in JAMA Oncology details clinical outcomes for 710 patients with brain metastases from small cell lung cancer treated with first-line stereotactic radiosurgery (SRS), without prior treatment with whole-brain radiation (WBRT) or prophylactic cranial irradiation (PCI).
A group of Japanese scientists has developed an ultrastable, selective catalyst to dehydrogenate propane - an essential process to produce the key petrochemical substance of propylene - without deactivation, even at temperatures of more than 600°C.
Palaeontologists from St Petersburg University have been the first to study in detail the structure of the brain and blood vessels in the skull of the ankylosaur Bissektipelta archibaldi. It was a herbivorous dinosaur somewhat similar in appearance to a modern armadillo. The first three-dimensional computer reconstruction of a dinosaur endocast made in Russia - a digital cast of its braincase - was of help to the scientists.
Research from the University of Sheffield has found that the chance of finding Earth-like planets in their early stages of formation is much higher than previously thought.
The team studied groups of young stars in the Milky Way to see if these groups were typical compared to theories and previous observations in other star-forming regions in space, and to study if the populations of stars in these groups affected the likelihood of finding forming Earth-like planets.
BOSTON - Long-term care facilities (LTCFs) are a major driver of total COVID-19 deaths. Reported today in the Journal of the American Geriatrics Society, Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) geriatricians Rossana Lau-Ng, Lisa Caruso and Thomas Perls studied the past month's case and death data reported by the Massachusetts Department of Health's COVID-19 daily Dashboard along with data provided by the Kaiser Family Foundation and other countries.
Cost model data published in U.S. Endocrinology show for commercially-insured people with diabetes on intensive insulin therapy, using FreeStyle Libre technology costs 60% less compared to traditional blood glucose monitoring
This cost-savings includes costs associated with severe hypoglycemia, including hospitalizations, which were approximately 50% less for FreeStyle Libre 14 day system users versus testing with traditional fingersticks
When we think of wrinkles, we usually envision the lines etched into our skin, for some an unwelcome reality and for others a proud sign of a life well-lived. In material science, wrinkles can also be either wanted or unwanted. But the physical factors that cause wrinkling to occur are not yet fully understood.
Researchers at Kumamoto University in Japan have discovered that uric acid, an antioxidant, protects against declining lung function from age or lung disease, especially in women. High uric acid levels can cause health problems such as gout and renal damage, but this study showed that it protects against lung function decline in females. The function of uric acid and other antioxidants in the lungs, as well as gender differences, will likely be considered for prospective management of lung diseases.
The team then examined these liquid jets using soft X-rays at BESSY II and subsequently has been able to analyse this process in detail from the data they acquired combined with theoretical predictions. The work has been published in Science and appears even on the cover.
Tsukuba, Japan - The presence of dreaming during rapid-eye-movement (REM) sleep indicates that memory formation may occur during this sleep stage. But now, researchers from Japan have found that activity in a specific group of neurons is necessary for memory consolidation during REM sleep.
In a study published this month in Neuron, researchers from University of Tsukuba and the University of Tokyo have revealed that adult-born neurons (ABNs) in the hippocampus, which is a brain region associated with memory, are responsible for memory consolidation during REM sleep.
The increase in antibiotic resistance and the lack of new antibiotics is currently a major global health problem. Reducing the use of antibiotics appears to be one of the only solutions to preserve their effectiveness and limit the emergence of resistance. Relatively long courses of treatment remain standard, however, although they seem to be based on medical tradition rather than on sound scientific evidence.
WESTMINSTER, Colorado - June 05, 2020 - Greenskeepers and landscape managers consider annual bluegrass to be a significant pest. It has an unsightly appearance, competes with desirable grasses, and produces an uneven surface that affects golf and other sports. In addition, the weed has now developed resistance to multiple herbicides.
What does it mean to be a metal and how is a metal formed? These seem like textbook questions with a simple answer: Metal is characterized by free electrons which give rise to its high electric conductivity. But how exactly is a metallic conduction band formed from originally localized electrons and what is the corresponding microscopic picture for the material involved?
