The area known as the Santana Group in the Araripe Basin in northeastern Brazil has long been an important fossil site, contributing significantly to knowledge of the Cretaceous period. In particular, it has yielded many specimens of pterosaurs. And now, a study, published in Scientific Reports, adds yet another valuable piece to the paleontological puzzle with the discovery of a new filter-feeding species of pterosaur. A unique specimen Perhaps the most interesting part of the discovery [...]

Researchers from the University of São Paulo (USP), in collaboration with the Federal University of Alfenas (UNIFAL), have identified high levels of toxic substances in plastic toys sold in Brazil. The study analyzed 70 domestically manufactured and imported products, making it the most comprehensive study ever conducted in Brazil on chemical contamination in children's products. The results were published in the journal Exposure and Health. Widespread violations of [...]

Insects that feed on starch can find veritable feasts in corn, pea, and bean crops or warehouses. It is no coincidence that the ancestors of these commercial plants developed α-amylase inhibitor proteins, which make the starch in their seeds indigestible to pests, keeping them from becoming serious threats. However, the domestication of wild plants by humans to increase productivity and digestibility may have reduced the presence of these inhibitors. Gene editing offers new pest [...]

A study conducted by the general and teaching hospital ("Hospital das Clínicas") of the Ribeirão Preto Medical School of the University of São Paulo (HCFMRP-USP) in Brazil followed 99 patients who underwent hip and knee replacement surgery in 2020. The study revealed that 32.3% of the patients experienced complications within 30 days of discharge, with 12.1% experiencing local infections. A similar concern arises in dentistry. In 2022, a study by the Federal [...]

Titan, Saturn's largest natural satellite, captivates scientists with its Earth-like processes, dense nitrogen atmosphere, and surface lakes of liquid hydrocarbons. However, its nonuniform gravity field, thick haze, and low solar energy pose major obstacles for orbital missions. Traditional single-satellite systems struggle to balance coverage, stability, and data transmission under such conditions. Moreover, the gravitational pull from Saturn and nearby moons further complicates orbital [...]

Paleontologists have identified a new species of flying reptile, named Bakiribu waridza. The most compelling detail of the discovery is the origin of the fossil: it was found in a regurgitalite, or fossilized puke, left by an unknown predator. Surprisingly, the trace fossil preserved the remains of an entirely new pterosaur species that was consumed and then regurgitated indigestibly. It is described as the first filter-feeding pterosaur from the tropics, found in the Araripe Basin of [...]

A computational study published in the Journal of Molecular Liquids makes important contributions to the development of new, safe, high-performance batteries by investigating compounds that can be used as electrolytes in sodium-ion batteries. The work involved the efforts of a team of researchers linked to the Center for Innovation on New Energies (CINE). Created in 2018, the CINE is based at the State University of Campinas (UNICAMP), the University of São Paulo (USP), and the [...]

A new site in one of the most important basins for humanity’s evolution has provided evidence of occupation over an unprecedented period. Across 300,000 years, the toolmakers maintained a similar style in the face of a harsh and changing climate, in contrast to places occupied much more briefly. Millions of years ago, the Turkana Basin in northern Kenya was a center of innovation for our ancestors, or possibly one of the related species known to have lived alongside them. A new [...]

Planting trees is not enough. Although forest restoration efforts in the Atlantic Forest are advancing on a large scale, they are still unable to fully integrate replanted areas into the mosaic of native fragments. This is the conclusion of a study conducted in Brazil and published in the Journal of Applied Ecology. The first authors of the article were Débora Cristina Rother, a professor at the Federal University of São Carlos (UFSCar) in the state of São [...]
