New research from UBC finds that after a night of shorter sleep, people react more emotionally to stressful events the next day--and they don't find as much joy in the good things. The study, led by health psychologist Nancy Sin, looks at how sleep affects our reaction to both stressful and positive events in daily life.
Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain how both immune cells and cancer cells migrate in various fluid-filled niches in the body, for good or for harm.
Sacramento, CA-- In 2018, Lin Tian and her team at UC Davis Health developed dLight1, a single fluorescent protein-based biosensor. This family of highly specific sensors detects dopamine, a hormone released by neurons to send signals to other nerve cells. When combined with advanced microscopy, dLight1 provides high resolution, real-time imaging of the spatial and temporal release of dopamine in live animals.
September 15, 2020 - Digital phenotyping approaches that collect and analyze Smartphone-user data on locations, activities, and even feelings - combined with machine learning to recognize patterns and make predictions from the data - have emerged as promising tools for monitoring patients with psychosis spectrum illnesses, according to a report in the September/
A molecule known as ACE2 sits like a doorknob on the outer surfaces of the cells that line the lungs. Since January 2020, researchers have known that SARS-CoV-2, the novel coronavirus that causes COVID-19, primarily uses ACE2 to enter these cells and establish respiratory infections. Finding a way to lock out that interaction between virus and doorknob, as a means to treat the infection, has become the goal of many research studies.
Boulder, Colo., USA: When early humans began to travel out of Africa and spread into Eurasia over a hundred thousand years ago, a fertile region around the eastern Mediterranean Sea called the Levant served as a critical gateway between northern Africa and Eurasia. A new study, published in Geology, shows that the existence of that oasis depended almost entirely on something we almost never think about: dust.

A new study, co-led by University of Cincinnati researchers, describes the development of a refining process that scientists deem a superior method to help produce better dietary omega-3 health and dietary supplements containing fish oil.
Fish oil is widely known to be an excellent dietary source of omega-3 polyunsaturated fatty acids (PUFAs) having positive effects on human health including heart and eye health, inflammation and bone density.
Roughly 1 in 10 patients diagnosed with COVID-19 needed to return to the hospital within a week of discharge from an emergency department visit, according to data from the first three months of the COVID-19 outbreak in the Philadelphia region--March, April and May 2020. Researchers in the Perelman School of Medicine at the University of Pennsylvania also found that factors like lower pulse oximetry levels and fever were some of the most telling symptoms that resulted in return trips that resulted in admission.
Final report card on Aichi Biodiversity Targets, set in 2010: 6 of world's 20 goals "partially achieved" by 2020 deadline.
Towards a landmark new global post-2020 biodiversity framework: GBO-5 synthesizes scientific basis for urgent action.
Bright spots include: extinctions prevented by conservation, more land and oceans protected, fish stocks bounce back in well-managed fisheries.
FLAGSTAFF, Ariz. -- Sept. 15, 2020 -- Initial findings reported by the Arizona COVID-19 Genomics Union (ACGU) suggest that following Arizona's first reported case of COVID-19 in late January, the state experienced no cases that went undetected and was COVID-free until at least 11 distinct incursions occurred between mid-February and early April.
The published results appear in the scientific journal mBio.
Tsukuba, Japan - Researchers led by the University of Tsukuba studied the vibrational modes of an intrinsically disordered protein to understand its anomalously strong response at low frequencies. This work may lead to improvements in our knowledge of materials that lack long-range order, which may influence industrial glass manufacturing.
EUGENE, Ore. - Sept. 15, 2020 - High school students who endure gender harassment in schools that don't respond well enter college and adulthood with potential mental health challenges, according to a University of Oregon study.
The study, published last month in PLOS ONE, found that 97 percent of women and 96 percent of men from a pool of 535 undergraduate college students had endured at least one instance of gender harassment during high school.
DENVER/September 14, 2020 – A genetic mutation might be the reason dogs with hypothyroidism are less likely to develop T-zone lymphoma (TZL). That’s the finding from Morris Animal Foundation-funded researchers at Colorado State University who tried to identify genetic risk factors for TZL using a genome-wide association study (GWAS) and subsequent targeted sequencing.
DALLAS, September 15, 2020 -- Patients with psoriasis treated with biologic therapy, which are protein-based infusions to suppress inflammation, had a significant reduction in high-risk plaque in heart arteries, over one-year, according to new research published today in Circulation: Cardiovascular Imaging, an American Heart Association journal.
