SpaceX Crew-11 splashed down safely in the Pacific after more than five months in orbit aboard the International Space Station. The four astronauts completed over 140 experiments and traveled nearly 71 million miles around Earth. NASA brought the crew home earlier than planned due to a medical concern, with officials confirming the affected crew member is stable. The mission underscores how quickly today’s space programs can adapt while keeping astronauts safe.

New research shows tropical forests can recover twice as fast after deforestation when their soils contain enough nitrogen. Scientists followed forest regrowth across Central America for decades and found that nitrogen plays a decisive role in how quickly trees return. Faster regrowth also means more carbon captured from the atmosphere. The study points to smarter reforestation strategies that work with nature rather than relying on fertilizers.

A new OLED design can stretch dramatically while staying bright, solving a problem that has long limited flexible displays. The breakthrough comes from pairing a highly efficient light-emitting material with tough, transparent MXene-based electrodes. Tests showed the display kept most of its brightness even after repeated stretching. The technology could power future wearable screens and on-skin health sensors.

A large international study reveals that mammals tend to live longer when reproduction is suppressed. On average, lifespan increases by about 10 percent, though the reasons differ for males and females. Castrated males avoid the harmful effects of testosterone, while females gain longevity by sidestepping the intense physical demands of pregnancy and nursing. The results underscore a powerful biological trade-off between making offspring and staying alive longer.

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.

Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate system goes awry, pushing tryptophan toward harmful byproducts linked to memory loss, mood changes, and sleep problems.

Scientists have uncovered how cannabis evolved the ability to make its most famous compounds—THC, CBD, and CBC—by recreating ancient enzymes that existed millions of years ago. These early enzymes were multitaskers, capable of producing several cannabinoids at once, before evolution fine-tuned them into today’s highly specialized forms. By “resurrecting” these long-lost enzymes in the lab, researchers showed how cannabis chemistry became more precise over time—and discovered something unexpected: the ancient versions are often more robust and easier to work with.

Hydrogen cyanide, a toxic chemical, may have helped spark the chemistry that led to life. When frozen, it forms crystals with highly reactive surfaces that can drive unusual chemical reactions, even in extreme cold. These reactions could produce more reactive molecules that pave the way for life’s basic ingredients. The findings suggest frozen worlds may be more chemically active than once thought.

For years, strange red dots in James Webb images left scientists puzzled. New research shows they are young black holes hidden inside dense clouds of gas, glowing as they devour their surroundings. These black holes are smaller than expected but grow rapidly, shedding light on how supermassive black holes appeared so early in cosmic history. The finding reveals a violent and messy phase of the universe’s youth.

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 particle-like behavior.

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 strategy for reducing dementia risk.

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.

“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 they replaced.

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.

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 diabetes overall.

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.

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, researchers reveal that “red-hot” dark matter could survive long enough to become the calm, structure-building force we see today.

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 materials, machines, and living cells.

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-related aches.

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.
