A father's diet doesn't just affect his own health. It may shape his child's body composition before the baby is even conceived. New research shows that fathers who eat more ultra-processed foods tend to have heavier babies. Those babies also accumulate more fat around the thighs and lower back. The study was coordinated by Daniela Sartorelli, a professor at the Ribeirão Preto School of Medicine at the University of São Paulo. Researchers followed 43 sets of fathers, [...]

For most of the antibiotic era, the plan for fighting bacteria has been blunt: kill them. Two research teams, one in Germany and one in Brazil, are testing a quieter idea. Their plant-derived compounds do not kill cells. They jam the molecular grip that lets disease take hold. A strategy older than antibiotics People reached for plants and fruits to treat illness long before anyone isolated a drug. Laboratories are now working out why some of those remedies actually helped. The timing [...]

The world's tallest tropical trees lift water to their highest leaves without strain, a new study has found. These giants – the dipterocarps that tower over the rainforests of Southeast Asia – rebuild their inner plumbing as they grow, so height never leaves them short of water. The finding overturns a long-held idea that giant trees struggle to stay hydrated and so die more readily in drought. Because the biggest trees hold much of a forest's carbon, that assumption sits inside [...]

In many fish species, water temperature determines the sex of offspring. As oceans warm, that mechanism has raised a troubling question: could entire fish populations collapse simply by running out of females?  A new ten-year study offers an unexpected and cautiously hopeful answer. In European seabass exposed to elevated temperatures, the initial spike in male births reversed itself by the third generation, with females coming back in greater numbers.  The warming effect, it turns [...]

Soybeans already sit inside a huge part of modern life. They feed chickens, pigs, cattle, and fish. They help make cooking oil, plant-based foods, and many processed products. So when soybeans change, the effects do not stop at the farm gate. A new study suggests that future climate conditions could push soybeans into an odd bargain: more beans, but weaker nutrition. Under the combined pressure of more carbon dioxide, higher heat, and drought , soybean plants may produce 50% more [...]

Deep beneath parts of Brazil's vast Cerrado landscape lies a carbon storehouse that has been quietly building for thousands of years. Scientists are discovering that these little-known wetlands may play a much bigger role in Earth's carbon cycle than previously understood. Ancient carbon hides underground The Cerrado is South America's second-largest biome and the most biodiverse savanna on Earth. Often called Brazil's cradle of waters, it supplies water to major [...]

For more than 200 years, a small brown moth quietly carried the same name. Scientists believed it was a single species, first described in 1818. It looked ordinary enough, measuring less than an inch across from wingtip to wingtip. Yet a closer look revealed a very different story. What seemed like one species was actually several. Hidden behind nearly identical appearances was a collection of distinct moths living in different parts of Brazil. Researchers from the State University of [...]

Sloths move so slowly that watching one in a dense jungle is its own kind of test. They have stayed hard to study for the same reason they are so beloved, hidden high in the trees and barely moving at all. Researchers have found a new place to look for answers. They turned to the sloth's own genome, and what they found there helps explain the slowest metabolism of any mammal . A team led by the Wellcome Sanger Institute, the Leibniz Institute for Zoo and Wildlife Research ( IZW ) in [...]

For decades, the story of how humans first populated South America was told in two chapters: an initial wave of migration around 12,000 years ago, and a second one roughly 9,000 years ago. However, a new study has found a third chapter that nobody had documented before. The research was coordinated by Tábita Hünemeier, a geneticist at the University of São Paulo’s Institute of Biosciences.  The team fully sequenced 128 genomes and compared them with 71 previously published [...]
