The transmission of malaria by the Anopheles cruzii mosquito in the South and Southeast of Brazil was so alarming in the 1940s—with approximately 4,000 cases per 100,000 people—that the disease became known as bromeliad malaria. This is because the Kerteszia subgenus of the mosquito, which transmits the disease in the Atlantic Forest, develops only in bromeliads, plants that accumulate water and maintain conditions favorable for the development of this and other species. Although [...]

Amid the preparatory discussions for COP30, which also involve health-related topics, a study contributes to our understanding of the relationship between deforestation and the spread of malaria in the Legal Amazon. This region encompasses all nine Brazilian states in which the Amazon biome is found and was established by the federal government for regional development purposes. The study shows that intermediate forest cover with 50% deforestation increases human cases of the disease and [...]

Brazilian researchers developed a new methodology to project how climate change will affect the physiology of livestock between 2050 and 2100. Findings show that small ruminants in the Northern Hemisphere and dairy cattle and poultry in the Southern Hemisphere will be most vulnerable to heat stress. The study discusses the need for adaptive genetics, resilient breeds, and sustainable policies to protect food security as global temperatures rise. DAILY Discussion Brazilian [...]

We live on a planet wrapped in a magnetic shield that waxes and wanes with solar activity. Most days, that quiet background barely draws notice. Some days, it fluctuates more strongly. The study behind this article asked a simple question: when Earth’s magnetic field gets unsettled, as it does during solar storms, is there a direct correlation to the number of heart attacks reported in humans on Earth? Doctors in Brazil analyzed hospital admissions for myocardial infarction (heart [...]

Astronomers have sounded the alarm about a worrisome group of 'invisible' asteroids that could pose a threat to Earth in the far-off future. While these objects have not yet been observed through telescopes, they are believed to have the potential to smash into our planet and devastate large cities within a 'few thousand years'. The peer-reviewed study, spearheaded by Brazil's São Paulo State University, utilized numerical simulations and cutting-edge models to gain a [...]

An international study led by researchers at São Paulo State University (UNESP) in Brazil has identified a little-known but potentially significant threat: Asteroids that share Venus's orbit and may completely escape current observational campaigns because of their position in the sky. These objects have not yet been observed, but they could strike Earth within a few thousand years. Their impacts could devastate large cities. "Our study shows that there's a population of [...]

No bones about it — tiny shreds of plastic can cause big problems for health. Microplastics are particles, smaller than a grain of rice, that are found in everything from the toothpaste we use to the clothes we wear and even the food we eat. These minute shards that slough off larger plastic have been shown to harm reproductive, digestive and respiratory health, potentially leading to colon and lung cancer. A new analysis out of Brazil suggests microplastics can have wide-ranging [...]

Parents can influence the physical activity levels of their childrenKids are more likely to become couch potatoes if Mom or Dad don’t move muchLikewise, children are more likely to be active if their parents exercise WEDNESDAY, Sept. 10, 2025 (HealthDay News) — Kids are more likely to become couch potatoes — or enthusiastically active — based on what they see their parents doing day-to-day, a new study says. The example set by moms and dads appears to contribute to [...]

Deforestation in the Brazilian Amazon is doing far more than clearing trees: it’s directly shrinking the region’s rain supply and nudging temperatures upward during the dry season. A new study led by scientists at the University of São Paulo (USP) is the first to put hard numbers on how much of the recent shift is due to local forest loss versus global climate change. The researchers found that deforestation accounts for roughly 74.5% of the observed decline in [...]
