Land deals meant to improve food security may have hurt

CORVALLIS, Ore. - Tiny amounts of gender bias in employee hiring decisions contribute to concerning rates of discrimination and productivity losses that together represent significant costs, financial and otherwise, for employers, a new study from Oregon State University has found. Gender bias is a subtle, unintentional preference for one gender over the other. Despite significant efforts to reduce bias in hiring over the last several decades, it continues to persist and pose potential problems for companies, said Jay Hardy, an assistant professor of management in OSU's College ...

BOZEMAN, Montana (January 19, 2021) - A four-year study recently published in Ecology and Evolution concludes that the fungal disease, white-nose syndrome, poses a severe threat to many western North American bats. Since it was first detected in 2006, white-nose syndrome has killed millions of bats in eastern and central North America. The spread of the fungal pathogen that causes white-nose syndrome in hibernating bats has reached several western U.S. states, mostly likely through bat-to-bat spread, and is presently threatening western species. Bats with white-nose syndrome have fungus growing on their nose and wings, as the name implies, but the fungal infection also triggers a higher frequency of arousals from hibernation. ...

Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or wandering. Using an electroencephalogram (EEG) to measure brain activity while people performed mundane attention tasks, researchers identified brain signals that reveal when the mind is not focused on the task at hand or aimlessly wandering, especially after concentrating on an assignment. Specifically, increased alpha brain waves were detected in the prefrontal cortex of ...

For the first time, scientists have successfully used satellite cameras coupled with deep learning to count animals in complex geographical landscapes, taking conservationists an important step forward in monitoring populations of endangered species. For this research, the satellite Worldview 3 used high-resolution imagery to capture African elephants moving through forests and grasslands. The automated system detected animals with the same accuracy as humans are able to achieve. The algorithm that enabled the detection process was created by Dr Olga Isupova, a computer scientist at the University of Bath in the UK. The project was a collaboration with the UK's University of Oxford and the University of Twente in the Netherlands. Dr ...

People's fear of 5G technology is rational. Such technology does emit radiation, even if it's at low levels. But 5G isn't all that different from 4G, and it certainly doesn't cause COVID-19 despite such rumors having spread rapidly across the globe. Researchers need to better understand how misinformation like this spreads in order to hone their intervention efforts and prevent misinformed perspectives from taking root. In society's virtual world, preventing technological misinformation, in particular, is important now more than ever. A research team led by Elaine Nsoesie, a Hariri Institute Faculty Fellow, investigated how COVID-19 misinformation proliferated using ...

A new study out of the University of Chicago and Stanford University on pairs of twins with and without food allergies has identified potential microbial players in this condition. The results were published on Jan. 19 in the Journal of Clinical Investigation. The study grew out of prior research in the Nagler laboratory at UChicago on the fecal microbiota in infants. By transplanting fecal microbes from healthy and food-allergic infants to germ-free mice (who do not possess a microbiome), investigators found that the healthy infant microbiota was protective against the development ...

The synthetic chemicals known as PFAS, short for perfluoroalkyl and polyfluoroalkyl substances, are found in soil and groundwater where they have accumulated, posing risks to human health ranging from respiratory problems to cancer. New research from the University of Houston and Oregon State University published in Environmental Science and Technology Letters suggests why these "forever chemicals" - so called because they can persist in the environment for decades - are so difficult to permanently remove and offers new avenues for better remediation practices. The work focused on the interactions sparked when firefighters use ...

The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study. The finding suggests that dietary change might help treat some people with the autoimmune disease. The study was published Jan. 19 in The Journal of Clinical Investigation. Fat tissue in patients diagnosed with MS lack normal levels of oleic acid, a monounsaturated fatty acid found at high levels in, for instance, cooking oils, meats (beef, chicken, and pork), cheese, nuts, sunflower seeds, eggs, pasta, ...

With a name like glucose-6-phosphate dehydrogenase deficiency, one would think it is a rare and obscure medical condition, but that's far from the truth. Roughly 400 million people worldwide live with potential of blood disorders due to the enzyme deficiency. While some people are asymptomatic, others suffer from jaundice, ruptured red blood cells and, in the worst cases, kidney failure. Now, a team led by researchers at the Department of Energy's SLAC National Accelerator Laboratory have uncovered the elusive mechanism behind the most severe cases of the ...

WASHINGTON, January 19, 2021 -- What causes brain concussions? Is it direct translational or rotational impact? This is one of the research areas currently being explored by Qianhong Wu's lab at Villanova University. Our brains consist of soft matter bathed in watery cerebrospinal fluid (CSF) inside a hard skull. An impact on the hard skull is transmitted through the thin layer of CSF within the subarachnoid space to the soft brain matter. In Physics of Fluids, from AIP Publishing, Wu and co-authors Ji Lang and Rungun Nathan describe studying another system with the same features, an egg, to search for answers. An egg resembles the brain, because its soft yolk is bathed within a liquid egg white inside a hard shell. Considering that in most concussive brain injuries, the skull does ...
