Trump-touted hydroxychloroquine shows no benefit in COVID-19 prevention: study

Trump began backing hydroxychloroquine early in the pandemic and told reporters in May he started taking the drug after two White House staffers tested positive for...

Rodent ancestors combined portions of blood and venom genes to make pheromones

Experts who study animal pheromones have traced the evolutionary origins of genes that allow mice, rats and other rodents to communicate through smell. The discovery is a clear example of how new genes can evolve through the random chance of molecular tinkering and may make identifying new pheromones easier in future studies. The results represent a genealogy for the exocrine-gland secreting...

Rapeseed instead of soy burgers: Researchers identify a new source of protein for humans

Rapeseed has the potential to replace soy as the best plant-based source of protein for humans. In a current study, nutrition scientists found that rapeseed protein consumption has comparable beneficial effects on human metabolism as soy protein. The glucose metabolism and satiety were even better. Another advantage: The proteins can be obtained from the by-products of rapeseed oil production.

Delirium a key sign of COVID-19 in frail, older people

A new analysis, using information from the COVID Symptom Study app and patients admitted to St Thomas' Hospital in London, has shown that delirium -- a state of acute confusion associated with a higher risk of serious illness and death -- is a key symptom of COVID-19 in frail, older people.

Wildcats threatened by their domestic cousins

European wildcats, thought to be extinct 50 years ago in the Jura mountains, have since recolonized part of their former territory. This resurgence in an area occupied by domestic cats has gone hand-in-hand with genetic crosses between the two species. A team of biologists modeled the interactions between the two species and predict that hybridization will entail the irreversible genetic...

New gas giant exoplanet discovered by NGTS survey

An international team of astronomers has discovered a new gas giant alien world as part of the Next Generation Transit Survey (NGTS). The newly found exoplanet, designated NGTS-12b, is about the size of Jupiter, but more than four times less massive than the solar system's biggest planet. The finding is reported in a paper published September 22 on arXiv.org.

A new study provides substantial evidence that the first fossil feather ever to be discovered does belong to the iconic bird-like dinosaur, Archaeopteryx. This debunks a recent theory that the fossil feather originated from a different species.

Breaking COVID-19's 'clutch' to stop its spread

The virus that causes COVID-19 uses a clutch-like shifter to enable transcription of one RNA string into multiple proteins, and therein lies a vulnerability. A proof-of-concept study shows it's possible to eliminate that shifter with an RNA-binding compound linked to a 'trash this' signal.
