The fossil assemblage was found in the state of Rio Grande do Sul, one of Brazil’s richest paleontological regions. The bones belonged to animals that lived between 247 million and 208 million years ago. It is difficult to confirm they can be considered species of dinosaur.
In vitro experiments showed cobalt-doped calcium phosphate to be capable of stimulating bone cell differentiation by mimicking a low-oxygen environment. Next steps include animal testing.
The Alliance and the WEF signed an agreement for five years to operate the Food Action Alliance and its flagships across the globe, especially in Latin America and the Caribbean.
The emergence of rabies in distinct wildlife species is a potential source of human infection and poses life-threatening risks. As the researchers responsible for the discovery warn, anyone who comes into contact with these animals should alert the authorities. A 36-year-old farm worker died in May, only weeks after being bitten by a marmoset.
The endangered coco de mer boasts a seed that is the undisputed world heavyweight, weighing 18 kilograms (40 pounds) or more. A deep genetic dive into its reproduction strategy may hold a crucial lesson for the tree’s survival - and people restoring landscapes everywhere.

An article published in PNAS by Brazilian and Australian researchers describes a hitherto unknown protein with anti-oxidizing properties secreted by Coxiella burnetii, a Gram-negative intracellular bacterium, pointing to possible treatments for auto-immune diseases and even cancer.
Results of trials involving animals, cell cultures and human heart tissue are reported in the European Heart Journal. The study was conducted by researchers at USP in partnership with a biopharmaceutical firm, offering hope to 2 million Brazilians who suffer from the disease.
