Study supports that Omicron variant has shifted to better usage of Cathepsin B/L entry pathway

The evolution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causal agent of the ongoing coronavirus disease 2019 (COVID-19) pandemic, has led to the emergence of many new variants. These variants are different from the original SARS-CoV-2 strain, which was first reported in China in 2019. Some of the emerged variants have been classified …

Scientists identify a new switch for controlling motor proteins

Scientists identify a new switch for controlling motor proteins

Inside neurons, motor proteins haul precious cargo, moving essential goods along thread-like roadways called microtubule tracks. This miniature highway system is vital for keeping neurons healthy: When traffic is flowing well, critical materials are able to reach distant areas of the cells where they’re needed. When the system breaks down, it can impede cellular function …

Scientists find predictors of heart disease among Black Americans that are shared across ethnicities

Scientists find predictors of heart disease among Black Americans that are shared across ethnicities

Credit: CC0 Public Domain Coronary heart disease, which is a major cause of heart attack, develops when damaged or clogged arteries cannot deliver enough oxygen-rich blood to the heart. Black Americans are at greater risk of coronary heart disease than non-Hispanic white individuals; however, because Black Americans are underrepresented in clinical research, established risk prediction …

Ancestral prepubertal cigarette smoking linked to higher body fat in females

Ancestral prepubertal cigarette smoking linked to higher body fat in females

A new study, led by the University of Bristol and published in Scientific Reports today [21 January], has reported increased body fat in females whose grandfathers or great-grandfathers began smoking before puberty. Experiments with model studies elsewhere have shown that exposure of males to certain chemicals before breeding can have effects on their offspring. There …

Vaccines alone are ineffective against the widely circulating Omicron variant

Vaccines alone are ineffective against the widely circulating Omicron variant

Millions of people around the world have received two shots of Sinovac, a Chinese-manufactured inactive vaccine that is used in 48 countries to help reduce transmission rates of COVID-19. However, those vaccinations alone are of no help against the widely circulating Omicron variant, show a new study by researchers at Yale and the Dominican Republic. …

Study explores methods to help reduce injury following successful post-concussion return-to-play

Children’s Hospital Colorado (Children’s Colorado) released a study today that examines the efficacy of a neuromuscular training (NMT) intervention that may lead to new treatment approaches and better outcomes for athletes when they return to playing sports after a sports-related concussion. While preliminary, the findings indicate the risk of sports-related injuries for the year after …
