Scientists from the Institute of Biology of the State University of Campinas (Brazil) have discovered that inhibitory molecules that suppress a specific protein called IL-22BP can have a positive effect on the intestinal microbiome and increase resistance to infections. published In the journal Proceedings of the National Academy of Sciences (PNAS). In experiments on mice, the researchers found that IL-22BP (a protein that binds to interleukin 22) reduced the amount of IL-22 protein needed [...]

Brazilian scientists from the Federal University of Sao Carlos have developed a technology to produce biosensors from fallen leaves using a carbon dioxide laser. The research was published in the scientific journal magazine ACS Sustainable Chemistry and Engineering (ACS SCE). The laser burns a figure of the desired shape onto a wood sheet, and its beam converts cellulose into graphite during the pyrolytic process. “We used a carbon dioxide laser to print a pattern of [...]

A huge amount of cocaine contamination in Brazilian waters could be making marine life high, with a range of severe effects. The drug has been found in the water and sediments of the Bay of Santos, one hour from the city of São Paulo, researchers at the Federal University of São Paulo (UNIFESP) have found. Santos, with its beach, is a popular destination for São Paulo residents and the area is home to the largest seaport in Latin America. Researchers found through a [...]

Brazilian biologists from the State University of Campinas in Sao Paulo have described for the first time how amphibians in South America use ultrasound to protect themselves from predators. The study was published in the scientific journal magazine Acta Ethologica. Experts observed this feature in Haddadus binotatus, a tree frog native to Brazilian forests. When calling for distress, the amphibian opens its mouth wide and throws its head back, and then emits a scream with a frequency of up [...]

Few places on earth are as isolated and untouched as Trindade Island, a volcanic formation in the middle of the Atlantic Ocean about three or four days’ sailing off the coast of Brazil. A place that has not yet entered human habitation and is 1,200 kilometers from the mainland. In theory, it’s perfect heaven. And yet This pristine place already has the dubious distinction of being the furthest place on Earth where rocks are made of moss. plastic. When geologist Fernanda Avelar [...]
