Loss of natural areas and introduction of exotic species reduce fishing yields in the Paraná River in Brazil
Publicado em 24 de julho de 2025
Fishing yields in the Upper Paraná River, on the border between the Brazilian states of São Paulo, Paraná, and Mato Grosso do Sul, have fallen by around 50% in two decades.
According to a study published in the journal Nature Ecology & Evolution, the decline is an effect of the invasion of exotic species and human occupation in the region.
The authors analyzed data collected from 2002 to 2022 by the Long-Term Ecological Program for the Upper [...]

Scientists discover surprising ingredient that could hold key to meat-free burgers: 'A more meat-like appearance and texture'
Publicado em 21 julho 2025These patties also provide essential amino acids your body needs for tissue repair. Sunflowers aren't just bright yellow blooms swaying in summer fields. Now, they might hold the key to your next meat-free burger. Phys.org reported that Brazilian and German scientists found a new way to turn sunflower flour into burger patties that could replace meat on your plate. Maria Teresa Bertoldo Pacheco of Brazil's Institute of Food Technology said, "It should also be noted that, [...]ver notícia -
Historical and current population DNA reveals at least 12 species of rocket frogs, three of which already extinct
Publicado em 17 julho 2025A group led by University of São Paulo (USP) researchers in Brazil has described a new genus of frogs, Dryadobates, also known as rocket frogs, which was previously considered a single species. The study was published in the Bulletin of the American Museum of Natural History. The researchers used techniques that allow the analysis of degraded DNA obtained from specimens preserved in alcohol or formalin and deposited in natural history collections. Adapted from [...]ver notícia -
Electrochemical route allows for synthesis of giant fullerenes at lower cost, less environmental impact
Publicado em 17 julho 2025A study conducted by researchers at the University of São Paulo (USP) in Brazil and the Università degli Studi di Roma "La Sapienza" in Italy has synthesized fullerenes and hollow spherical graphene particles using only natural graphite, ethanol, water, and sodium hydroxide under ambient conditions. Published in the journal Diamond and Related Materials , the research showed the feasibility of producing structures that previously required extremely high temperatures [...]ver notícia -
Sensory-motor activity protocol increases reading speed of children with dyslexia
Publicado em 02 julho 2025After following a protocol of sensory-motor activities with cognitive engagement for two months, eleven children aged 10 to 12 who were diagnosed with dyslexia showed improvement in reading speed. This initiative combined recreational activities that incorporated motor and social skills, demonstrating promise in improving children's reading performance. The results of the study were published in the journal Applied Neuropsychology: Child "Although this is a study involving a [...]ver notícia -
Women with low muscle mass may have a worse prognosis in breast cancer treatment
Publicado em 01 julho 2025Maintaining muscle mass has proven to be crucial for patients undergoing cancer treatment. Studies have shown that individuals with more muscle tend to respond better to therapies such as chemotherapy and radiotherapy. They also have a lower risk of complications and experience more effective recovery. This is because muscle plays an essential role in metabolism, helping to regulate the inflammatory response and drug absorption. Conversely, cancer patients with low muscle mass have a higher [...]ver notícia -
Rethinking our relationship with CO₂—greenhouse gas could lead to development of sustainable fuels
Publicado em 01 julho 2025The goal of carbon dioxide (CO2) hydrogenation is to turn pollution into fuel. This process transforms CO2, one of the main greenhouse gases, into chemical products and renewable fuels. One important product is methanol, a versatile compound used in everything from plastics to fuels. Other compounds can also be produced, such as methane, which can be injected directly into natural gas pipelines. Hydrocarbons with longer chains can be produced as well and can be used as gasoline or aviation [...]ver notícia -
The protein agrin is essential for balancing bone tissue, research finds
Publicado em 01 julho 2025A recent discovery could transform our understanding of bone health maintenance and pave the way for potential treatments for bone diseases, including osteoporosis. Researchers at the University of São Paulo's Ribeirão Preto School of Dentistry (FORP-USP) in Brazil have identified a protein called agrin that plays an essential role in preserving bone mass and quality. The research ispublishedin theInternational Journal of Biological Macromolecules. Osteocytes originate [...]ver notícia -
Seeing men as the 'default' may be tied to attitudes towards politicians and Black people
Publicado em 25 junho 2025In an international study, participants' attitudes toward 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. Prior research has shown how people often discuss [...]ver notícia -
A hidden asteroid family may share Venus' orbit: 'It's like discovering a continent you didn't know existed'
Publicado em 24 junho 2025Astronomers 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 [...]ver notícia
