Early in the U.S. COVID-19 pandemic, unemployment claims were largely driven by state shutdown orders and the nature of a state's economy and not by the virus, according a new article by Georgia State University economists.
ORNL story tips: Volcanic microbes, unbreakable bonds and flood mapping
Georgia State University biology researchers have found that infecting the nasal passages of mice with the virus that causes COVID-19 led to a rapid, escalating attack on the brain that triggered severe illness, even after the lungs were successfully clearing themselves of the virus.
Aged, wild-caught African green monkeys exposed to the SARS-CoV-2 virus developed acute respiratory distress syndrome (ARDS) with clinical symptoms similar to those observed in the most serious human cases of COVID-19, report researchers in The American Journal of Pathology, published by Elsevier. This is the first study to show that African green monkeys can develop severe clinical disease after...
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.
Aside from regular ice, water can exist in the form of peculiar solids called clathrate hydrates, which trap small gaseous molecules. They play a large role in the evolution of atmospheres, but predicting their presence in cryogenic temperatures is difficult. In a recent study, scientists from Okayama University developed statistical mechanics theory to determine their presence in Pluto and some...
This knowledge could help researchers design new diagnostics, evaluate the healing powers of convalescent plasma, develop new therapeutic treatments, and -- importantly -- help design future vaccines or monoclonal antibody therapies capable of protecting against mutations that may occur in the COVID-19 virus. The findings could help explain the widely varying reactions COVID-19 patients have to...
Ultra-small nanomedicines with a size of ca. 18 nm were fabricated by dynamic ion-pairing between Y-shaped block copolymers and oligonucleotide drugs. Chemically modified and double-stranded oligonucleotides dramatically enhanced the stability of the ultra-small nanomedicines in the bloodstream. The size allows for high permeability in cancer tissues by slipping through the cracks in tumor...
Researchers captured and comparted hi-res images of ribosome structures from sensitive and resistant bacteria and report that a water molecule needed for antibiotic binding was not present in the ribosomes from the drug-resistant bugs.
New research on predicting the earth's future climate: Using gravitational-wave science, a group of international scientists, including Australian OzGrav astrophysicist Ilya Mandel, studied ancient marine fossils as a predictor of climate change.
Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by the University of California, 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.
Open access (OA) democratizes access to research literature, but OA authors are more likely to be males in STEM fields at wealthier institutions.
The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better...
Disasters in high-risk industries can have catastrophic environmental, financial and human safety consequences. One way these industries help prevent and mitigate disasters is formal procedures designed to standardize how work is done. These procedures typically come in the form of a written document workers use while performing a task.
Youths with mood disorders who use and abuse cannabis (marijuana) have a higher risk for self-harm, death by all causes and death by unintentional overdose and homicide, according to research led by The Ohio State University Wexner Medical Center and The Ohio State University College of Medicine.
Fried-food intake is linked to a heightened risk of major heart disease and stroke, finds a pooled analysis of the available research data.
Government obesity policies in England over the past three decades have largely failed because of problems with implementation, lack of learning from past successes or failures, and a reliance on trying to persuade individuals to change their behavior rather than tackling unhealthy environments.
New research has demonstrated that a simple, cheap test can help identify who is at risk of developing colorectal cancer, aiding early diagnosis and potentially saving lives.
Young Seychelles warblers fare better if their elderly parents have help raising them, according to new research from the University of East Anglia (UEA) and the University of Groningen.
