A fossilised 113-million-year-old hell ant from Brazil adds to the evidence that the first ants evolved in the southern hemisphere before moving north – and beyond A 110-million-year-old fossil of the hell ant Vulcanidris cratensis Anderson Lepeco At more than 110 million years old, a fossil excavated in Brazil is the oldest undisputed ant fossil ever discovered. The finding adds to evidence that the first ants evolved on the supercontinent of Gondwana in the southern hemisphere [...]

Motivated by this kind of consideration, researchers at São Paulo State University (UNESP) in Rio Claro, Brazil, used concepts of condensed matter physics to describe protein compartmentalization in cells and proposed a cellular Griffiths-like phase in direct analogy to the canonical magnetic Griffiths phase. The study is published in the journal Heliyon. The last author and PI is Mariano de Souza, a professor at the Institute of Geosciences and Exact Sciences (IGCE-UNESP), and the [...]

Bacteria in the soil enhance the attractiveness of the plant's flowers to pollinators via a type of relationship known as mutualism that is widespread in plants and animals. Microorganisms such as bacteria or fungi contribute to and benefit from mutualistic relationships with plants, whereby both sides obtain more nutrients or reproduce more vigorously, for example. In the case of C. latistipula, a shrub with a native range spanning Bolivia, Brazil and northeast Argentina, the soil it [...]

A flurry of studies has found microplastics in nearly every organ in the human body, from the brain to the testicles. But very few have revealed whether these tiny bits of plastic impact our health. It seems every few months, we discover microplastics in a new part of the body. We have found them in our livers, kidneys, lungs and guts. They have even shown up in human breast milk and blood. Last week, they turned up again in eight people’s olfactory bulbs, a brain structure [...]

"Do a real study, then we can talk about the data." -- Theo Heller, MD, of the National Institute of Diabetes and Digestive and Kidney Diseases in Bethesda, Maryland, on the lack of adequate data to support obeticholic acid (Ocaliva) for primary biliary cholangitis. "In the ocean, they get into the food chain, and they get into us." -- Luís Fernando Amato-Lourenco, PhD, of Freie Universität Berlin, talking about microplastics and a new study that detected them [...]

Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open. Mounting research over the last few years has found microplastics in nearly every organ in the body, as well as in the bloodstream and in plaque that clogs arteries. Whether these ubiquitous pollutants can reach the human brain has been a primary concern for scientists. The latest research looked at a part of the brain called [...]

Research conducted at the Center for Dairy Technology (Tecnolat) in Campinas, São Paulo state, Brazil, has identified lactic acid bacteria (LAB) that have probiotic properties and are beneficial to human health in samples of traditional Brazilian cheeses. Tecnolat is part of the Food Technology Institute (ITAL), an arm of the São Paulo State Department of Agriculture and Supply. The findings are published in the journal Current Microbiology. The researchers analyzed three [...]
