COLUMBUS, Ohio - Infusing prepared foods with an edible coating that contains green tea extract may lower consumers' chances of catching the highly contagious norovirus by eating contaminated food, new research suggests.
Norovirus, which causes vomiting and diarrhea, sickens an estimated 48 million people in the United States every year and causes about 3,000 deaths. It's transmitted from person to person and through consumption of contaminated water and food.
Inside your mouth right now, there is a group of bacteria whose closest relatives can also be found in the belly of a moose, in dogs, cats, and dolphins, and in groundwater deep under the Earth's surface. In a stunning discovery, scientists have found that these organisms have adapted to these incredibly diverse environments--without radically changing their genomes.
Researchers at the University of Bath have been working with GB skeleton athletes to develop a new type of motion capture technology that can accurately track the performance of the athlete during push start phase of performance.
Biomedical engineers at Duke University have engineered a method for simultaneously detecting the presence of multiple specific microRNAs in RNA extracted from tissue samples without the need for labeling or target amplification. The technique could be used to identify early biomarkers of cancer and other diseases without the need for the elaborate, time-consuming, expensive processes and special laboratory equipment required by current technologies.
The results appeared online on May 4 in the journal Analyst.
Seated around the dinner table, faculty affiliated with Stanford ChEM-H - one of Stanford University's interdisciplinary institutes - spoke one-by-one, pitching ideas for collaborative research. Inspired by a recent medical conundrum, Gilbert Chu, a professor of medicine (oncology) and of biochemistry at Stanford Medicine, put out the call for a chemist who could help him create a sensor that could quickly, easily and accurately measure ammonia levels in blood.
The rod-like spike proteins on the surface of SARS CoV-2 are the tip of the spear of the COVID-19 pandemic. The spikes bind to human cells via the ACE2 receptor and then dramatically change shape, jack-knifing to fuse the cell membrane with the coronavirus's outer membrane and opening the door to coronavirus infection. A study led by Boston Children's Hospital for the first time freeze-frames the spike protein in its "before" and "after" shapes.
Scientists report two new cryo-EM structures representing the pre- and postfusion conformations of the full-length SARS-CoV-2 spike (S) protein, an essential viral component responsible for host cell entry and the spread of infection. These reconstructions - derived from a full-length, fully wild-type form of the S protein - demonstrate critical differences from previous cryo-EM studies that used engineered, stabilized versions of the S protein.
Airborne and potentially deadly, the virus that causes COVID-19 can only be studied safely under high-level biosafety conditions. Scientists handling the infectious virus must wear full-body biohazard suits with pressurized respirators, and work inside laboratories with multiple containment levels and specialized ventilation systems. While necessary to protect laboratory workers, these safety precautions slow down efforts to find drugs and vaccines for COVID-19 since many scientists lack access to the required biosafety facilities.
Irvine, CA - July 21, 2020 - Patients with Alzheimer's disease frequently suffer from spatial memory loss, such as no recognition of where they are, and forgetting where they put their belongings. They often show a wandering symptom, which is also a feature of spatial memory impairment. Until now, the brain network mechanism that causes spatial memory impairment had been unclear.
COLUMBUS, Ohio - Despite the political tensions between the United States and China, scientists in the two countries are working together more than ever to study the COVID-19 virus, a new study suggests.
Researchers analyzed the scientific papers that researchers around the world produced on coronaviruses before and after the arrival of COVID-19. They found that the United States and China were world leaders in the topic area before COVID-19 and they remain so now.

More than 1 in 5 U.S. homes lack sufficient space and plumbing facilities to comply with recommendations to limit household spread of COVID-19
CORVALLIS, Ore. - The global population of the critically endangered Chinese crested tern has more than doubled thanks to a historic, decade-long collaboration among Oregon State University researchers and scientists and conservationists in China, Taiwan and Japan.
The project included OSU's Dan Roby and Don Lyons and was led by Chen Shuihua of the Zhejiang Museum of Natural History. When it began, fewer than 50 of the seabirds remained.
For the first time, scientists at the Morgridge Institute for Research have generated near atomic resolution images of a major viral protein complex responsible for replicating the RNA genome of a member of the positive-strand RNA viruses, the large class of viruses that includes coronaviruses and many other pathogens.
The results should aid development of new types of antivirals and provide mechanistic insights into the virus life cycle.
DURHAM, N.C. -- A chance mutation that led to spinal defects in a zebrafish has opened a little window into our own fishy past.
Rising fifth-year Duke graduate student Brianna Peskin, who started the project during her first-year rotation in Michel Bagnat's cell biology lab and "kinda kept coming back to it," was merely trying to figure out why this one mutation led to developmental issues in a zebrafish's spine.
Argonne researchers quantify how to reduce emissions by farms changing their practices and adopting novel technologies.
