An unusual offering in an abandoned and unique-looking Maya sweat bath revealed new evidence of the role it played in the community

An enzyme associated with energy production in cells also participates in the differentiation of immune cells involved in exacerbated inflammation. The discovery could lead to more effective treatment.

New research published in Nature Communications Earth & Environment uses data from two sustained open-ocean hydrographic stations (Hydrostation 'S' and the Bermuda Atlantic Time-series Study) in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The study shows decadal variability and recent acceleration of surface warming, salinification, deoxygenation, and changes in carbon dioxide (CO₂)-carbonate chemistry that drives ocean acidification.

Laboratory tests showed film containing silver-silica nanoparticles to be capable of eliminating 99.84% of SARS-CoV-2 particles after exposure for two minutes.

Conclusion presented by Brazilian researchers in Obesity Research & Clinical Practice is based on analysis of nine clinical studies involving 6,577 patients infected by SARS-CoV-2 in five countries.

The identity of wild cloning sea star larvae has been a mystery since they were first documented in the Caribbean. The most commonly collected cloning species was thought to belong to the Oreasteridae, on the basis of similarity with sequences from Oreaster reticulatus and Oreaster clavatus.

Model developed by Brazilian researchers predicts spatial and temporal evolution of epidemic diseases and can help plan more effective social isolation programs with less socio-economic impact.

An article in The Lancet stresses the vulnerability of these health workers, whose readiness to counter fake news with trustworthy information, and to monitor COVID-19 patients in home isolation, has been neglected.

North American mammals were the winners when the North and South American continents collided millions of years ago. New research shows that South American mammals went extinct at a disproportionately high rate once the Panama Isthmus connected the continents, allowing migration in either direction.
