A study by the Center for Redox Processes in Biomedicine ( Redoxoma ) led by Marilene Demasi from the Butantan Institute (São Paulo, Brazil) presents a valuable new experimental model for investigating the interaction between the proteasome and mitochondrial function. In eukaryotic cells, the proteasome is a protein complex responsible for eliminating damaged and nonfunctional proteins, thereby helping to maintain cellular balance and proper [...]

Preliminary results presented at the FAPESP Week France health conference suggest the venom from an Amazon rainforest scorpion (Brotheas amazonicus) might be able to help treat breast cancer. An aging global population, as well as greater exposure to pollutants and stressed-out ecosystems, means we are seeing increasing rates of cancer, dementia, and other diseases. So, in the endless search for more treatment options, some researchers are looking in unlikely places – like a [...]

In an international study, participants' attitudes towards certain social groups—namely, politicians and Black people—were more strongly related to their attitudes towards the men than the women of each group, suggesting that men are the "default" for attitudes towards these groups. Curtis Edward Phills of the University of Oregon, U.S., and colleagues present these findings in the open-access journal PLOS One on June 25, 2025. Prior research has shown how people [...]

Seeing men as the “default” may be tied to attitudes to politicians, Black people In study, attitudes on these groups were more in line with attitudes on men than women of each group In an international study, participants’ attitudes towards certain social groups—namely, politicians and Black people—were more strongly related to their attitudes towards the men than the women of each group, suggesting that men are the “default” for attitudes [...]

An article published in the journal Nature Metabolism presents an experimental drug that stimulates adipose tissue cells to produce heat through a process known as thermogenesis, thereby promoting weight loss. In animal tests, the compound prevented fat accumulation in response to a high-fat diet, treated existing obesity, and reversed associated metabolic disorders, including insulin resistance. Preliminary results from clinical research indicate that the substance is safe and may have [...]

Researchers from the Institute of Food Technology (ITAL) and the University of Campinas (UNICAMP), both in the state of São Paulo, Brazil, in collaboration with scientists from the Fraunhofer IVV Institute in Germany, have developed a food product made from sunflower flour that can be used as a meat substitute. The ingredient is obtained by extracting oil from the seeds of the plant. In order for it to be consumed by humans, the husks and phenolic compounds from the grains must be [...]

Astronomers are investigating a little-known and largely unseen group of asteroids that quietly orbit the sun alongside Venus — and there may be many more of them than we thought. "It's like discovering a continent you didn't know existed," Valerio Carruba of the São Paulo State University in Brazil, who led the analysis, told Space.com. "It's very likely there are other asteroids we don't observe today." These space rocks, known as " [...]

According to a new study, combining exercise with omega-3 supplements reduced inflammation and, thereby, the severity of a chronic tooth root infection. It suggests a relatively simple means of controlling these infections, which can result in bone and tooth loss. Apical periodontitis (AP) occurs when bacteria reach the tip, or apex, of a tooth root and cause inflammation of the surrounding tissues. It can be caused by tooth decay, trauma, or following dental procedures. If left untreated, [...]
