Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, carrying a small but real amount of energy known as vacuum energy, or dark energy. While this energy is overwhelmed by matter in galaxies and clusters, in the deep emptiness of cosmic voids it becomes dominant.

Prediction market Kalshi has taken action against three political candidates, alleging that each was engaged with insider trading of information about their campaigns. The company implemented new rules last month aimed at preventing politicians and athletes from placing bets on events they can control, and it said those guardrails helped to flag this trio of cases. The three candidates are Mark Moran of Virginia, Matt Klein of Minnesota and Ezekiel... Read more ›

A long-running dinosaur mystery may finally be solved: Nanotyrannus, once dismissed as just a teenage T. rex, appears to have been its own distinct species after all. Scientists analyzed a tiny throat bone from the original fossil and discovered growth patterns showing the animal was already mature, not a juvenile giant-in-the-making. This smaller predator—about half the size of a full-grown T. rex—likely roamed alongside its famous cousin, adding a new... Read more ›

A surprising new clinical trial has revealed that metformin—a cheap, century-old drug widely used for type 2 diabetes—may help people with type 1 diabetes in an unexpected way. While researchers initially hoped it would reduce insulin resistance, they instead found it allows patients to use about 12% less insulin while maintaining stable blood sugar levels. Read more ›

New research suggests that aiming for a lower blood pressure target may deliver bigger heart health benefits than previously thought. Using large datasets and simulation models, scientists found that keeping systolic blood pressure below 120 mm Hg could reduce the risk of heart attack, stroke, and heart failure more than higher targets.

Scientists have discovered that methane in the open ocean is produced by microbes under nutrient-poor conditions, solving a long-standing mystery. As warming oceans reduce nutrient mixing, these methane-producing microbes may thrive. This could lead to increased methane emissions from the sea. The result is a potential feedback loop that could intensify climate change. Read more ›

A massive, nearly 20-year study tracking over 650,000 Americans with irritable bowel syndrome is raising new questions about the long-term safety of common treatments. Researchers found that some widely used medications—including antidepressants and certain antidiarrheal drugs—were linked to a small but noticeable increase in the risk of death over time.

The ozone layer has been on track to recover thanks to the Montreal Protocol—but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected. Scientists now estimate this could delay ozone recovery by up to seven years. Closing this gap could speed up healing and reduce harmful UV exposure worldwide. Read more ›

A rogue set of “zombie” immune cells may be driving aging and fatty liver disease by flooding tissues with inflammation. Researchers found these cells accumulate with age and high cholesterol—and can make up most of the liver’s immune cells in older mice. When scientists removed them, liver damage was dramatically reversed, even without diet changes. Read more ›

Scientists have discovered that a protein linked to cell death is secretly driving the aging of blood stem cells in a completely different way. Instead of killing the cells, it damages their mitochondria, sapping their energy and weakening the immune system over time. When this protein was turned off, stem cells remained stronger and more balanced, even under stress. The findings point to a new strategy for slowing aging at... Read more ›

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. Read more ›
