The modified strain grows protein far more quickly and with much less sugar while producing substantially fewer emissions. It also outperforms chicken farming in land use and water impact.

Scientists confirmed that West Coast transient killer whales actually form two separate groups split between inner and outer coastal habitats. Inner-coast whales hunt smaller prey in shallow, maze-like waterways, while outer-coast orcas pursue large marine mammals in deep offshore canyons. The groups rarely interact, despite sharing a broad range along the Pacific Coast. Their contrasting lifestyles highlight the need for distinct conservation strategies.

New climate modeling shows that heatwaves will keep getting hotter, longer, and more frequent for centuries—even after the world hits net-zero emissions. Delays of just a few years dramatically increase the likelihood of extreme, once-rare heat disasters, especially for countries near the equator. The research reveals that even reaching net zero by mid-century won't reverse the trend, and some regions will continue to see worsening heatwaves for a thousand years.

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers after its primordial magma-ocean era.

Researchers have launched the first coordinated plan to protect microbial biodiversity, calling attention to the “invisible 99% of life” that drives essential Earth systems. The IUCN has formally recognized this effort through the creation of the Microbial Conservation Specialist Group.

In the future, it may support more personalized treatment strategies.

A nationwide analysis has uncovered how sprawling fossil fuel infrastructure sits surprisingly close to millions of American homes. The research shows that 46.6 million people live within about a mile of wells, refineries, pipelines, storage sites, or transport facilities. Many of these locations release pollutants that may affect nearby communities, yet mid-supply-chain sites have rarely been studied. The findings reveal major gaps in understanding how this hidden network affects health.

Experts say the ocean could help absorb carbon dioxide, but today’s technologies are too uncertain to be scaled up safely. New findings released during COP30 highlight the risks of rushing into marine carbon removal without proper monitoring and verification. With the 1.5°C threshold approaching, researchers stress that emissions cuts must remain the top priority. Ocean-based methods may play a role later, but they need careful oversight first.

Chameleons’ extraordinary ability to move their eyes independently stems from a previously overlooked anatomical marvel: long, tightly coiled optic nerves hidden behind their bulging eyes. Modern CT imaging finally revealed this structure, which centuries of dissections and even the scrutiny of figures like Aristotle and Newton failed to capture. The coils give the eyes extra slack, enabling nearly 360-degree scanning without neck mobility.

Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by cyanobacteria living directly on the drifting algae. Coral cores reveal that this nutrient engine has intensified over the past decade, perfectly matching surges in Sargassum growth since 2011. By ruling out older theories involving Saharan dust and river runoff, researchers uncovered a climate-driven process that shapes when and where these colossal seaweed mats form.

Researchers discovered that ancient peat bogs grew rapidly when the Southern Westerly Winds suddenly shifted thousands of years ago. These wind changes affected both peatland carbon storage and how the Southern Ocean absorbed CO₂. Today the winds are shifting southward again, driven by climate change. Scientists warn this could disrupt natural carbon sinks and worsen droughts and wildfires.

Microplastics—tiny particles now found in food, water, air, and even human tissues—may directly accelerate artery-clogging disease, and new research shows the danger may be far greater for males. In mice, environmentally realistic doses of microplastics dramatically worsened plaque buildup, altered key vascular cells, and activated harmful genes linked to inflammation and atherosclerosis, all without changes to weight or cholesterol.

Researchers have discovered chemical traces of life in rocks older than 3.3 billion years, offering a rare look at Earth’s earliest biology.

Across the planet, animals are increasingly suffering from chronic illnesses once seen only in humans. Cats, dogs, cows, and even marine life are facing rising rates of cancer, diabetes, arthritis, and obesity — diseases tied to the same factors affecting people: genetics, pollution, poor nutrition, and stress. A new study led by scientists at the Agricultural University of Athens proposes a unified model linking these conditions across species.

Hawaiian short-finned pilot whales are surprisingly voracious hunters, diving hundreds of meters beneath the Pacific to snatch squid in the dark. By tagging and tracking eight whales, researchers uncovered just how much energy these deep-sea forays require—and how many squid the whales must eat to stay fueled. Their calculations reveal that each whale downs dozens to hundreds of squid per day, adding up to a staggering 88,000 tonnes of squid consumed annually by the whole population.

Penn State scientists identified a striking rise in melanoma across several Pennsylvania counties dominated by cropland and herbicide use. The elevated risk persisted even after factoring in sunlight, suggesting an environmental influence beyond the usual expectations.

The work highlights how fragile the Greenland ice system has become as temperatures rise.

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. Seismic activity confirmed this wasn’t just floating ice but grounded mass contributing to sea level rise. The event raises alarms that other fragile glaciers may be poised for similar, faster-than-expected collapses.

Bumble bees battling invasive Argentine ants may win individual fights but ultimately lose valuable foraging time, putting pressure on colonies already strained by habitat loss, disease, and pesticides. New research shows bees often avoid ant-occupied feeders, and while their size helps them win one-on-one clashes, these encounters trigger prolonged aggression that keeps them from collecting food.

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.
