Omega-3 fish oil shows promise against type 2 diabetes
Publicado em 31 de maio de 2026
Fish oil may help switch off inflammation-driven insulin resistance—even in type 2 diabetes patients who aren't overweight.
Summary:
A new study suggests fish oil may help reduce insulin resistance even in people who aren't obese. In diabetic rats, omega-3 supplementation improved blood sugar levels, cholesterol, and inflammation by shifting immune cells into a more anti-inflammatory mode.
Fish oil rich in omega-3s helped reverse insulin resistance and improve blood sugar [...]

Scientists discover a mysterious silicone pollutant that may be everywhere
Publicado em 13 maio 2026Scientists have discovered a surprisingly abundant airborne silicone pollutant that may pose hidden risks to both human health and the climate. Date: May 13, 2026 Source: Utrecht University, Faculty of Science Summary: Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, likely linked to [...]ver notícia -
Stunning fossil discovery challenges the origins of animal life
Publicado em 12 maio 2026A stunning fossil reanalysis suggests some of Earth’s “earliest animals” were actually ancient bacteria and algae hiding in plain sight. Date: May 12, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life. What were once thought to be trails left behind by tiny worm-like creatures are now believed to be fossilized [...]ver notícia -
Scientists find natural compounds that hit COVID-19 from every angle
Publicado em 08 maio 2026A Brazilian tree’s natural compounds may fight COVID-19 on multiple fronts—making them a promising new antiviral lead. Date: May 7, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering [...]ver notícia -
Vitamin D boosts breast cancer treatment success by 79%
Publicado em 28 abril 2026A common vitamin could double chemotherapy success rates. Date: April 28, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: A daily vitamin D supplement may quietly supercharge chemotherapy. In a small study, women who took low doses alongside treatment were far more likely to see their cancer vanish than those who didn’t. Since vitamin D also supports immune function—and many patients are deficient—it could be playing a bigger role than [...]ver notícia -
This common plant could clean microplastics from your drinking water
Publicado em 20 abril 2026A humble plant could help clean microplastics from water—no harsh chemicals needed. Date: April 20, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists have discovered that moringa seeds can help pull microplastics out of water, rivaling standard chemical treatments. The plant-based extract causes plastic particles to clump together, making them easier to filter away. In some conditions, it even outperformed conventional chemicals. This [...]ver notícia -
Scientists supercharge immune cells to destroy cancer more effectively
Publicado em 17 abril 2026Date: April 16, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Researchers have found a way to make cancer-killing immune cells more powerful and precise. By adding specific signaling components, they boosted the cells’ readiness to attack tumors. Surprisingly, briefly suppressing the cells with a drug before use made them even more effective later. The approach could help create safer, stronger next-gen cancer treatments. Researchers in [...]ver notícia -
Artificial saliva made from sugarcane protein protects teeth from acid and decay
Publicado em 05 abril 2026A breakthrough sugarcane protein may soon protect teeth like natural saliva—even when the body can’t. Date: April 5, 2026 Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even better when paired with fluoride [...]ver notícia -
Some dinosaurs could rise up like giants — until they grew too big
Publicado em 30 março 2026Some dinosaurs could stand tall like giants—but only when they were young enough to pull it off. Summary: Certain smaller sauropods could stand on their hind legs with surprising ease, giving them access to higher food and a defensive edge. Computer simulations show their bones handled stress better than those of their larger relatives. However, as they grew, the sheer weight made this posture much harder to sustain. What started as a useful trick in youth became a more limited, [...]ver notícia -
This dangerous combo in your body could raise death risk by 83%
Publicado em 27 março 2026Summary: Having both excess belly fat and low muscle mass isn't just unhealthy—it's potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and inflammation. Researchers found it can be identified using simple measurements, not costly medical tests. That means earlier detection—and a real chance to intervene before serious decline sets in. Researchers from the Federal [...]ver notícia
