First coronavirus similar to MERS is found in bats in South America

Detected in the state of Ceará, Brazil, the novel coronavirus has similarities with the coronavirus that causes Middle East respiratory syndrome, first identified in 2012. Experiments to find out whether it can infect humans are set to take place during 2025.

Discovery by researchers at a FAPESP-supported research center could boost studies on the biological role of h15-LOX-2 and the development of new drugs.


Material shows potential for use in drug delivery and tissue support systems in the human body.

Application of iron sulfate in a degraded area of the Chapada dos Veadeiros National Park, in central Brazil, reduced nutrient availability and contained exotic species, allowing grasses typical of the Cerrado biome, adapted to poor soils, to regrow.

In rodent experiments, a cellulose product with silver nanoparticles was able to reduce microbial colonies in skin lesions, speeding up healing; treatment could benefit people with diabetic foot, burns, and bedridden patients with pressure ulcers.
