The COVID-19 pandemic could result in net losses from $3.2 trillion and up to $4.8 trillion in U.S. Real Gross Domestic Product (GDP) over the course of two years, a new USC study finds.
Does poverty cause lying? An international research team led by behavioral economist Agne Kajackaite from the WZB Berlin Social Science Center, Suparee Boonmanunt (Mahidol University, Bangkok) and Stephan Meier (Columbia Business School) examined whether poverty-stricken individuals were especially prone to acts of dishonesty. The researchers ran a field experiment with rice farmers in Thailand which incentivized cheating during a card game. They found that poverty itself did not cause individuals to act dishonestly.
LAWRENCE -- Researchers from the University of Kansas have described a galaxy more than 5.25 billion light years away undergoing a rarely seen stage in its galactic life cycle. Their findings recently were published in the Astrophysical Journal.
The galaxy, dubbed CQ 4479, shows characteristics that normally don't coexist: an X-ray luminous active galactic nuclei (AGN) and a cold gas supply fueling high star formation rates.
When the famous Spanish physician Santiago Ramón y Cajal looked through his microscope in 1910, he discovered irregular and "transparent lumps" that appeared throughout the nucleus of a neuron. What these nuclear speckles are all about is still largely unclear, even though the biological and medical sciences have experienced several revolutions since then. "Even though we know quite a bit about their function, we didn't know how nuclear speckles originate, i.e. what their core consists of," says Tuçe Akta from the Max Planck Institute for Molecular Genetics.
Men with muscles like a young Arnold Schwarzenegger look powerful but a handshake will give away whether they're a healthy specimen - or at risk of a chronic disease or premature ageing, experts say.
Medical researchers in South Australia, led by respiratory and sleep expert Professor Robert Adams, assessed more than 600 men aged over 40 to 88 years in the Men, Androgen, Inflammation, Lifestyle, Environment, and Stress (MAILES) study to measure the link between sleep apnea and muscle mass with grip strength.
UNIVERSITY PARK, Pa. -- Two genes that are important for the diverse colors and patterns of warbler plumage have evolved through two very different processes, according to a new study led by Penn State researchers. These evolutionary processes could help explain the rapid evolution of these songbirds into so many unique species.
PHILADELPHIA-- The labyrinth of jumbled blood vessels in the tumor microenvironment remains one of the toughest blockades for cellular therapies to penetrate and treat solid tumors. Now, in a new study published online today in Nature Cancer, Penn Medicine researchers found that combining chimeric antigen receptor (CAR) T cell therapy with a PAK4 inhibitor drug allowed the engineered cells to punch their way through and attack the tumor, leading to significantly enhanced survival in mice.
Researchers at ELTE Department of Ethology in Budapest compared how young companion dogs and companion pigs seek human proximity in a novel environment. It turned out that both dogs and pigs stay close to their owner if no other person is present; but if a stranger is also there, only dogs stay near humans, pigs prefer to stay away. The study reveals that living in a human family is not enough for early developing a general human preference in companion animals, species differences weigh in.
BEER-SHEVA, Israel...November 30, 2020 - An end-to-end cyber-biological attack, in which unwitting biologists may be tricked into generating dangerous toxins in their labs, has been discovered by Ben-Gurion University of the Negev cyber-researchers.
More than one-third of kids who have COVID-19 are asymptomatic, according to a University of Alberta study that suggests youngsters diagnosed with the disease may represent just a fraction of those infected.
"The concern from a public health perspective is that there is probably a lot of COVID-19 circulating in the community that people don't even realize," said Finlay McAlister, a professor of medicine in the Faculty of Medicine & Dentistry.
Understanding the sequence of human DNA gives scientists information about diseases, including potentially how to diagnose or treat them. In a new paper published in Nature Biotechnology, scientists from the School of Life Sciences at the University have shown that it is now possible to selectively sequence fragments of DNA more quickly and cost effectively than previously, without searching through DNA strands that are not relevant to the biological question, reaching that answer quicker than before.
What The Study Did: Researchers linked administrative health care and demographic data from Medicare to the Federal Reserve Bank of New York/Equifax Consumer Credit Panel to characterize the financial presentation of Alzheimer disease and related dementias before and after diagnosis.
Authors: Lauren Hersch Nicholas, Ph.D., M.P.P., of the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins University School of Medicine in Baltimore, is the corresponding author.
What The Study Did: Nationally representative data were used to examine if racial disparities in the occurrence of dementia in the United States changed from 2000 to 2016.
Authors: Melinda C. Power, Sc.D., of George Washington University in Washington, D.C., is the corresponding author.

What The Study Did: This observational study assessed whether receiving unemployment insurance is associated with lower health-related social needs, better health care access and better mental health during the COVID-19 pandemic.
Authors: Seth A. Berkowitz, M.D., M.P.H., of the University of North Carolina at Chapel Hill, is the corresponding author.
