Recent research shows that certain plant extracts and fruit fibers may boost the immune system and even reduce the risk of chronic diseases. Researchers from the University of Munich and the Federal University of Minas Gerais (UFMG) are teaming up to explore the power of medicinal plants in treating urinary tract infections (UTIs). At a lecture during FAPESP Week Germany at the Free University of Berlin, the team shared that they are building infection models to investigate how plant [...]

The findings emerge from a collaboration between researchers from Brazil and Switzerland, who combined species distribution data with climate modeling. Most amphibians will lose their habitats The experts cross-referenced locations of amphibian species with two greenhouse gas emissions scenarios (one optimistic, one pessimistic). The team concluded that more than 80% of amphibian species in the Upper Paraguay River Basin would lose suitable habitats. In the optimistic scenario, 99.87% of [...]

A recent study has discovered a surprising behavior in lemon leafcutter ants (Atta sexdens). These ants not only exhibit social immunity – the ability to detect and remove pathogens to protect their colony – but also appear to remember past infections and respond more aggressively to familiar threats. The research, led by São Paulo State University (UNESP), reveals that leafcutter ants can recognize a pathogenic fungus they have previously encountered, even 30 days after [...]

A new analysis of genetic studies proposes that the cognitive capacity for language was already present at least 135,000 years ago, with language likely becoming a social tool around 100,000 years ago. The study challenges long-standing debates about the timing of language emergence. The research was conducted by a team led by Shigeru Miyagawa, a linguist at the Massachusetts Institute of Technology (MIT), alongside Rob DeSalle and Ian Tattersall from the American Museum of Natural [...]

In the hidden corners of the world, caterpillars and ants have a remarkably specialized relationship. The caterpillars secrete a sweet, nectar-like substance that ants feed on, and the ants often protect the growing caterpillars from predators. This interesting relationship, which exists between ants and the larvae of some species of the Riodinidae family (metalmark butterflies), is so particular that each species of caterpillar interacts with only one species of ant. Scientists have now [...]

Deep in Brazil’s semi-arid Caatinga region, capuchin monkeys are teaching scientists valuable lessons about social learning and group dynamics. Recent research has uncovered that these remarkable primates don’t just learn new skills by watching others – the social bonds and tolerance levels within their groups play a crucial role in knowledge transmission. The remarkable study was led by Camila Galheigo Coelho during her doctoral research at the University of São [...]

Have you ever wondered about the impact of a father’s health on the birth weight of his newborn baby? Well, a recent study from Brazil involving 89 families draws a fascinating connection. When it comes to a dad’s weight, it seems the heavier the father is, the lower the baby’s birth weight. The study was led by Mariana Rinaldi Carvalho, a researcher at the University of São Paulo’s Ribeirão Preto Medical School. She has bravely challenged the [...]

Brazilian scientists have made a fascinating discovery about the history of maize, also known as corn. They’ve found traces of this ancient, partially domesticated plant in Brazil, which is farther from the crop’s historic point of origin in Mexico than any other similar evidence. But the story doesn’t just end here. The maize specimens discovered by the scientists were found hidden away in the Peruaçu Valley of Minas Gerais state, and they offer a fresh [...]

Global plant emissions are estimated at 500 to 600 million tons of isoprene annually, constituting about half of all gaseous organic compounds released by vegetation. The Amazon rainforest was found to be responsible for over a quarter of these emissions. Rainforest emissions beyond the canopy Previously, scientists believed that isoprene in the Amazon basin broke down rapidly and did not reach higher layers of the atmosphere. This breakdown was attributed to hydroxyl radicals – [...]
