Previous sinus or skull base surgery of an extensive nature is cause for re-evaluating whether to do nasopharyngeal swab testing to detect COVID-19, a new study that included authors from UT Health San Antonio indicates. Other testing, such as at the back of the throat, may be warranted instead.
New research shows that the more animals know about each other, the more they may be able to optimize their aggression.
New computer simulation forecasts a surprisingly optimistic heat load for future fusion facilities designed to harvest on Earth the fusion that powers the sun and stars to generate electricity.
Equitable implementation of COVID?19 vaccine delivery is a national and global priority, with a strong focus on reducing existing disparities and not creating new disparities. But while a framework has been recognized for equitable allocation of COVID?19 vaccine that acknowledges the rights and interests of sexual and gender minorities (SGM), it fails to identify strategies or data to achieve that goal.
COVID?19 has altered the labor market for millions of people, including public health graduates, yet an analysis of job postings for Master's level public health graduates showed that job postings remained at the same levels as before the pandemic, according to a new study at Columbia University Mailman School of Public Health.
Shark scientists at Georgia Aquarium, Scripps Institution of Oceanography at UC San Diego, and Dalhousie University are challenging the status quo in shark and ray mating research in a new study that looks at biological drivers of multiple paternity in these animals.
A mutation that replaces a single amino acid in a potent tumor-suppressing protein makes it prone to nucleating amyloid fibrils implicated in many cancers as well as neurological diseases.
Harvard Medical School researchers reconstructed the evolutionary history of cancer cells in two patients, tracing the timeline of the mutation that causes the disease to a cell of origin. In a 63-year-old patient, it occurred at around age 19; in a 34-year-old patient, at around age 9.
A systematic screening program designed for athletes testing positive for COVID-19 has detected a low incidence of inflammatory heart disease, so far returning professional athletes safely to sport.
Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.
