Scientists discover why mental disorders so often overlap
Publicado em 03 de janeiro de 2026
A large international team of scientists is shedding new light on a long-standing puzzle in mental health: why many people are diagnosed with more than one psychiatric disorder over their lifetime. In research published December 10 in the journal Nature, the group presents the most extensive and detailed investigation so far into the shared genetic foundations of 14 psychiatric conditions.
The work was led by the Psychiatric Genomics Consortium's Cross-Disorder Working Group. The group [...]

A traditional Brazilian plant shows unexpected strength against arthritis
Publicado em 22 dezembro 2025A humble Brazilian coastal plant used in folk medicine is now backed by science as a potential natural fighter against inflammation and arthritis. Date: December 22, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A Brazilian study has confirmed that Joseph’s Coat, a plant used for generations in folk medicine, can significantly reduce inflammation and arthritis symptoms in lab tests. Researchers observed less swelling, healthier joints, and [...]ver notícia -
Harvard gut discovery could change how we treat obesity and diabetes
Publicado em 14 dezembro 2025Gut-microbiome metabolites may hold the key to new treatments for obesity and type 2 diabetes. Date: December 14, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver cells when tested in the lab. The [...]ver notícia -
Natural hormone unlocks a hidden fat burning switch
Publicado em 06 dezembro 2025FGF19 may unlock a powerful new brain-driven mechanism to burn fat and combat obesity. Date: December 6, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: FGF19 triggers the brain to burn more energy and activate fat-burning cells, offering a potential new path for obesity treatments. The hormone enhances thermogenesis and reduces inflammation, but only when the sympathetic nervous system is active. Researchers uncovered how cold exposure increases [...]ver notícia -

Publicado em 28 novembro 2025Summary: A sweeping investigation reveals shockingly high toxic-metal contamination in Brazilian children’s toys, demanding immediate safety action. Date: November 28, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A large-scale Brazilian study found dangerous levels of toxic metals in popular children’s toys, with barium and lead topping the list. Researchers used sophisticated lab methods to identify 21 [...]ver notícia -
Scientists warn half the world's beaches could disappear
Publicado em 27 novembro 2025Rising seas and human pressures are rapidly shrinking the world’s beaches and destabilizing the ecosystems that depend on them. Date: November 27, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Human development and climate-driven sea level rise are accelerating global beach erosion and undermining the natural processes that sustain coastal ecosystems. Studies reveal that urban activity on the sand harms biodiversity in every connected zone, [...]ver notícia -
Simple molecule shows remarkable Alzheimer's reversal in rats
Publicado em 19 novembro 2025A low-cost, copper-targeting molecule from Brazil may offer a powerful new way to combat Alzheimer’s. Date: November 19, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists have developed a new molecule that breaks down beta-amyloid plaques by binding to excess copper in the brain. The treatment restored memory and reduced inflammation in rats, while also proving non-toxic and able to cross the blood–brain [...]ver notícia -
Amazon scorpion venom shows stunning power against breast cancer
Publicado em 18 novembro 2025Date: November 18, 2025 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists are turning venom, radioisotopes, engineered proteins, and AI into powerful new tools against cancer. From Amazonian scorpions yielding molecules that kill breast cancer cells as effectively as chemotherapy, to improved fibrin sealants and custom-grown bioactive factors, researchers are pushing biotechnology into uncharted territory. Parallel teams [...]ver notícia -
2.7-million-year-old tools reveal humanity's first great innovation
Publicado em 04 novembro 2025Ancient hominins in Kenya’s Turkana Basin crafted the same style of stone tools for 300,000 years, weathering fire, drought, and shifting ecosystems. Date: November 4, 2025 Source: George Washington University Summary: Researchers uncovered a 2.75–2.44 million-year-old site in Kenya showing that early humans maintained stone tool traditions for nearly 300,000 years despite extreme climate swings. The tools, remarkably consistent across generations, helped our [...]ver notícia -
Sunflowers may be the future of "vegan meat"
Publicado em 04 novembro 2025Sunflower flour emerges as a sustainable, nutrient-packed, and surprisingly meat-like plant protein innovation. Researchers enriched the product with tomato powder, spices, and a mixture of fat sources made up of sunflower, olive, and linseed oils. Credit: Unicamp Researchers at the Institute of Food Technology (ITAL) and the University of Campinas (UNICAMP) in São Paulo, Brazil, working with colleagues from the Fraunhofer IVV Institute in Germany, have developed a new type of food [...]ver notícia
