Statins may help almost everyone with type 2 diabetes live longer

15:18
New research suggests statins may protect adults with type 2 diabetes regardless of how low their predicted heart risk appears. In a large UK study, statin use was linked to fewer deaths and major cardiac events across all risk levels. Even those labeled “low risk” benefited, challenging long-held assumptions about who should receive preventive therapy. Side effects were rare and generally mild.

Electrons stop acting like particles—and physics still works

15:18
Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, researchers at TU Wien have discovered something surprising: a material where this particle picture completely breaks down can still host exotic topological states—features once thought to depend on part…

This after-meal blood sugar spike may raise Alzheimer’s risk

14:08
Spikes in blood sugar after eating may be more dangerous for the brain than previously thought. In a massive genetic study, people with higher post-meal blood sugar had a much greater risk of Alzheimer’s disease. The effect couldn’t be explained by visible brain damage, suggesting hidden biological pathways may be involved. Researchers say managing blood sugar after meals could become a key strat…

Forest loss is driving mosquitoes’ thirst for human blood

14:08
In the rapidly disappearing Atlantic Forest, mosquitoes are adapting to a human-dominated landscape. Scientists found that many species now prefer feeding on people rather than the forest’s diverse wildlife. This behavior dramatically raises the risk of spreading dangerous viruses such as dengue and Zika. The findings reveal how deforestation can quietly reshape disease dynamics.

Scientists question the safety of BPA-free packaging

14:08
“BPA-free” food packaging may be hiding new risks. A McGill University study found that several BPA substitutes used in grocery price labels can seep into food and interfere with vital processes in human ovarian cells. Some triggered unusual fat buildup and disrupted genes linked to cell repair and growth. The results raise concerns that BPA replacements may be just as troubling as the chemical t…

Northwestern Medicine’s new antibody wakes the immune system against pancreatic cancer

14:08
Pancreatic cancer uses a sugar-coated disguise to evade the immune system, helping explain why it’s so hard to treat. Northwestern scientists discovered this hidden mechanism and created an antibody that strips away the tumor’s protective signal. In animal tests, immune cells sprang back into action and tumors grew much more slowly. The team is now refining the therapy for future human trials.

A 3,000-year high: Alaska’s Arctic is entering a dangerous new fire era

7:21
For thousands of years, wildfires on Alaska’s North Slope were rare. That changed sharply in the 20th century, when warming temperatures dried soils and fueled the spread of shrubs, setting the stage for intense fires. Peat cores and satellite data reveal that fire activity since the 1950s has reached record levels. The findings suggest the Arctic is entering a new, more dangerous fire era.

New research challenges the cold dark matter assumption

7:21
Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as scientists long believed. New research shows that dark matter particles could have been moving near the speed of light shortly after the Big Bang, only to cool down later and still help form galaxies. By focusing on a chaotic early era known as post-inflationary reheating, researc…

How everyday foam reveals the secret logic of artificial intelligence

7:21
Foams were once thought to behave like glass, with bubbles frozen in place at the microscopic level. But new simulations reveal that foam bubbles are always shifting, even while the foam keeps its overall shape. Remarkably, this restless motion follows the same math used to train artificial intelligence. The finding hints that learning-like behavior may be a fundamental principle shared by materi…

Scientists uncover a hidden type of diabetes in newborns

15.ledna
Researchers have discovered a rare new type of diabetes that affects babies early in life. The condition is caused by changes in a single gene that prevent insulin-producing cells from working properly. When these cells fail, blood sugar rises and diabetes develops, often alongside neurological problems. The findings help explain a long-standing medical mystery and deepen understanding of diabete…

Scientists finally uncover why statins cause muscle pain

14.ledna
A new discovery may explain why so many people abandon cholesterol-lowering statins because of muscle pain and weakness. Researchers found that certain statins can latch onto a key muscle protein and trigger a tiny but harmful calcium leak inside muscle cells. That leak may weaken muscles directly or activate processes that slowly break them down, offering a long-sought explanation for statin-rel…

This sweet fruit is packed with hidden health compounds

14.ledna
Scientists are taking a closer look at monk fruit and discovering it’s more than just a sugar substitute. New research shows its peel and pulp contain a rich mix of antioxidants and bioactive compounds that may support health. Different varieties offer different chemical profiles, hinting at unique benefits. The work could shape how monk fruit is used in future foods and supplements.

“Marine darkwaves”: Hidden ocean blackouts are putting sealife at risk

14.ledna
Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine darkwaves” dramatically reduce light reaching the seafloor, putting kelp forests, seagrass, and other light-dependent life at risk.

Massive brain study reveals why memory loss can suddenly speed up with age

14.ledna
A massive international brain study has revealed that memory decline with age isn’t driven by a single brain region or gene, but by widespread structural changes across the brain that build up over time. Analyzing thousands of MRI scans and memory tests from healthy adults, researchers found that memory loss accelerates as brain tissue shrinkage increases, especially later in life. While the hipp…

The ocean absorbed a stunning amount of heat in 2025

14.ledna
Earth’s oceans reached their highest heat levels on record in 2025, absorbing vast amounts of excess energy from the atmosphere. This steady buildup has accelerated since the 1990s and is now driving stronger storms, heavier rainfall, and rising sea levels. While surface temperatures fluctuate year to year, the ocean’s long-term warming trend shows no sign of slowing.
