COLD SPRING HARBOR, NEW YORK -- In an important, comprehensive, and timely review, an expert team from the University of California Berkeley details the methodologies used in nucleic acid-based tests for detecting the presence of SARS-CoV-2, the virus that causes COVID-19. They show that these tests vary widely in applicability to mass screening and urge further improvements in testing technologies to increase speed and availability.
According to a UC Davis study, adolescents and young adults with autism spectrum disorder (ASD) and those with typical development show similar proactive cognitive control. However, symptoms of depression in individuals with autism were linked to less proactive control.
Researchers at the Beckman Institute at the University of Illinois at Urbana-Champaign have developed a new technique that can determine the specific molecular form, location, and the amount of lipids in samples of rat brain tissue. The technique provides more information than previous methods.
Traditional stroke treatments like clot-dissolving tPA and surgical removal of big clots in the brain are good choices as well when the stroke results from SARS-CoV-2 infection, investigators report.
Medical personnel treating coronavirus cases in China have higher rates of anxiety and other mental health symptoms than the general population, according to a new study in the open-access journal PLOS ONE by Ning Sun of Ningbo College of Health Science in Ningbo China, and colleagues.
To better understand and mitigate the health risks faced by astronauts from exposure to space radiation, we ideally need to be able to test the effects of Galactic Cosmic Rays (GCRs) here on Earth under laboratory conditions. An article publishing on May 19, 2020 in the open access journal PLOS Biology from Lisa Simonsen and colleagues at the NASA Langley Research Center, USA, describes how NASA has developed a ground-based GCR Simulator at the NASA Space Radiation Laboratory (NSRL), located at Brookhaven National Laboratory.
Dr. Akhilesh K. Gaharwar, associate professor, has developed a highly printable bioink as a platform to generate anatomical-scale functional tissues. This study was recently published in the American Chemical Society's Applied Materials and Interfaces.
Bioprinting is an emerging additive manufacturing approach that takes biomaterials such as hydrogels and combines them with cells and growth factors, which are then printed to create tissue-like structures that imitate natural tissues.
Palm oil is often associated with tropical deforestation above all else. However, this is only one side of the story, as agricultural scientists from the University of Göttingen and the IPB University Bogor (Indonesia) show in a new study. The rapid expansion of oil palm has also contributed considerably to economic growth and poverty reduction in local communities, particularly in Asia. The study was published in the Annual Review of Resource Economics.
The organ of balance in the inner ear is surrounded by the hardest bone in the body. Using synchrotron X-rays, researchers at Uppsala University have discovered a drainage system that may be assumed to play a major role in the onset of Ménière's disease, a common and troublesome disorder. These results are published in the journal Scientific Reports.
Bethesda, MD (May 19, 2020) -- Gastroenterology, the official journal of the American Gastroenterological Association (AGA), has released a special issue providing clinicians and researchers an up-to-date resource on the risk factors, natural history, diagnosis and treatment of nonalcoholic fatty liver disease (NAFLD).
In a new study, researchers from the Colorado School of Public Health at the University of Colorado Anschutz Medical Campus call attention to the emergence of mosquito-borne viral outbreaks in West Africa, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses.
The findings are published in the current issue of Acta Tropica.
ANN ARBOR, Michigan -- Recent large-scale efforts to categorize the molecular data of multiple cancer types has yielded so much information that researchers now have a new question: How to turn all this data into meaningful information that guides cancer research and patient care.
A new analytic tool developed by University of Michigan Rogel Cancer Center researchers combines multiple data sets to help sift the signal from the noise.
As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism. In fact, mitochondria decline with age not only in humans, but in many species. Why they do so is not well understood. Scientists at the Max Planck Institute for Biology of Ageing in Cologne set out to understand how mitochondrial function is diminished with age and to find factors that prevent this process.
AUSTIN, Texas -- Seeing someone do something good for someone else motivates witnesses to perform their own helpful acts, an insight that could help drive cooperative behavior in communities navigating through the health crisis.
Scientists working at caesar have developed a small head-mounted microscope that allows access to the inner workings of the brain. The new system enables measurement of activity from neuronal populations located in the deep cortical layer with single-cell resolution, in an animal that is freely behaving.
