Ultra-endurance athletes can push their bodies to extraordinary extremes, but even they run into a hard biological wall. Researchers tracked ultra-runners, cyclists, and triathletes over weeks and months, discovering that no matter how intense the effort, the human body maxes out at about 2.5 times its basal metabolic rate when measured long-term. Short bursts of six or seven times BMR are possible, but the body quickly pulls energy away from other functions to compensate, nudging athletes back toward the ceiling.

Scientists studying aging found that sensory inputs like touch and smell can cancel out the lifespan-boosting effects of dietary restriction by suppressing the key longevity gene fmo-2. When overactivated, the gene makes worms oddly indifferent to danger and food, suggesting trade-offs between lifespan and behavior. The work highlights how deeply intertwined the brain, metabolism, and environment are. These pathways may eventually be targeted to extend life without extreme dieting.

Hektoria Glacier’s sudden eight-kilometer collapse stunned scientists, marking the fastest modern ice retreat ever recorded in Antarctica. Its flat, below-sea-level ice plain allowed huge slabs of ice to detach rapidly once retreat began.

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth. The findings also help explain why Earth and the other rocky planets remained near 1 AU rather than plunging inward.

Researchers have designed a smart drug that hunts down and breaks a little-known RNA that cancer cells depend on. The drug recognizes a unique fold in the RNA and triggers the cell to destroy it. Tests showed that removing this RNA slows cancer growth. The approach could lead to new treatments that attack cancer at its most fundamental level.

Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth—sometimes resembling meteorite water.

After decades of confusion, scientists have linked it to the cnidarian family. The find deepens our understanding of how animals first learned to build their own skeletons.

Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function — including inflammation, loss of protective species, and overactive metabolic pathways — may drive disease progression. Intriguingly, even “good” bacteria like Faecalibacterium prausnitzii and Akkermansia muciniphila can become harmful under certain conditions.

New research from the Technical University of Munich and Harvard Medical School reveals that popular GLP-1-based drugs, semaglutide (Ozempic) and tirzepatide (Mounjaro), not only promote weight loss but also significantly reduce the risk of heart attacks and strokes in patients with type 2 diabetes. Using real-world insurance data, the study found up to an 18% reduction in major cardiovascular events, confirming powerful heart-protective effects that appear to extend beyond weight control.

GLP-1 drugs such as Ozempic and Wegovy may extend the lives of colon cancer patients, according to a major UC San Diego study. Patients on the medications had less than half the mortality rate of non-users. Researchers suspect the drugs’ anti-inflammatory and metabolic effects contribute to improved outcomes. They’re now calling for clinical trials to test whether these findings reflect a true anti-cancer mechanism.

Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental roots and push them deep into the oceanic mantle. Data from the Indian Ocean confirms this hidden recycling process, which can last tens of millions of years.

In a first-of-its-kind study, scientists found that bumblebees can tell the difference between short and long light flashes, much like recognizing Morse code. The insects learned which signal led to a sweet reward, demonstrating an unexpected sense of timing. This ability may stem from a fundamental neural process, suggesting that even tiny brains have complex time-tracking mechanisms relevant to evolution and AI.

Researchers scanning soccer fans’ brains found that wins trigger bursts of reward activity while losses dampen control signals. The results show how loyalty and rivalry can override logic, turning competition into an emotional storm. The same brain circuits that fuel sports passion may also underlie political or social fanaticism. Early experiences, the study suggests, shape whether these circuits lead to healthy excitement or explosive reactions.
