Brazilian supercentenarians are revealing genetic secrets to extreme longevity, defying expectations of healthy lifestyles. Scientists are studying over 160 centenarians, including 20 supercentenarians, to understand how they reach advanced ages despite limited access to healthcare. Early findings suggest genetic diversity, not diet or exercise, may be key. The DNA Longevo study highlights Brazil's mixed ancestry, offering a unique perspective compared to more homogeneous populations [...]

A new species of sugarcane pest, Mahanarva diakantha, has been identified in Brazil. This discovery may impact pest management strategies and crop losses. Researchers used morphological and genetic analyses to distinguish Mahanarva diakantha from similar species. The pest's distinct male genitalia and wing shape were key identifiers. The identification of this cryptic species necessitates re-evaluation of past studies and opens avenues for targeted research into its distribution and [...]

Intermediate forest degradation in the Amazon increases malaria risk, with 50% deforestation correlating to higher human cases and mosquito infection rates. A study in Acre, Brazil, found that fragmented vegetation and 50% forest loss create optimal conditions for malaria transmission by Anopheles mosquitoes. The findings, published in Acta Tropica, highlight the need for integrated vector control and forest conservation efforts, especially ahead of COP30 discussions on health and environmental [...]

A computational study reveals two South American long-necked dinosaurs could easily stand on their hind legs. This ability, observed in Uberabatitan and Neuquensaurus, likely aided in defense and feeding on high foliage. Researchers used engineering simulations to analyze stress on their leg bones. The findings suggest smaller sauropods had a structural advantage for bipedal stances, useful for various behaviors like mating and predator deterrence.

Ancient stony corals survived extreme environmental changes, suggesting some modern species may also be resilient to climate change impacts. Research published in Nature reconstructed the evolutionary tree of stony corals, dating their common ancestor to 460 million years ago. This study analyzed genomes of 274 species. The findings indicate that non-symbiotic deep-water corals persisted through past anoxic events, offering potential insights for conservation efforts.  

Scientists discovered a bacterium in Antarctica that produces a sugar polymer with potential for food, cosmetics, and medicine. The exopolysaccharide from Bacillus licheniformis strain F2LB offers antioxidant protection, stability, and texture improvement, surpassing commercial polymers. This eco-friendly, biodegradable compound could replace synthetic materials in various industries and aid in environmental cleanup. yahoo.com

Amazon rainforest trees are growing larger due to increased atmospheric carbon dioxide, suggesting greater resilience to climate change. A new international study found that the average trunk size of Amazonian trees has increased in recent decades, indicating CO2 is aiding their growth despite climate change concerns. Researchers emphasize the importance of protecting existing tropical forests, as newly planted trees may not offer the same carbon or biodiversity benefits as mature, [...]

What is News Minimalist? It's the only news aggregator that ranks news by significance. It uses AI (ChatGPT) to read and analyze ~30,000 news articles every day and give them a significance score from 0 to 10. Articles rated 0-3 usually cover sports, entertainment, and small local news. Articles with rating 5+ cover significant world events that shape the world. To give a global perspective, the news is collected in 12 most spoken languages. Why? I wanted to have this for [...]

A study found significantly higher microplastic levels in crabs than in mangrove mud in São Paulo's coast. The research revealed up to 1200% more microplastics in crabs, posing risks to both the animals and human consumers. This bioaccumulation highlights the need for public awareness regarding improper waste disposal and its impact on marine ecosystems. g1.globo.com (Portuguese)
