A new study reveals that chemicals used to replace ozone-damaging CFCs are now driving a surge in a persistent “forever chemical” worldwide. The pollutant, called trifluoroacetic acid, is falling out of the atmosphere into water, land, and ice, ...
Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice ...
Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far ...
As demand for critical metals grows, scientists have taken a rare, close look at life on the deep Pacific seabed where mining may soon begin. Over five years and 160 days at sea, researchers documented nearly 800 species, many previously unknown. ...
SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA ...
Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying ...
Small mammals are early warning systems for environmental damage, but many species look almost identical, making them hard to track. Scientists have developed a new footprint-based method that can tell apart nearly indistinguishable species with ...
Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into ...
After analyzing 40 years of tree records across the Andes and Amazon, researchers found that climate change is reshaping tropical forests in uneven ways. Some regions are steadily losing tree species, especially where conditions are hotter and ...
Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth’s most powerful climate defenses. New research suggests microplastics are disrupting marine life that helps oceans absorb carbon dioxide, while also releasing ...
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 ...
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 ...

The search for life on Earth is speeding up, not slowing down. Scientists are now identifying more than 16,000 new species each year, revealing far more biodiversity than expected across animals, ...

The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds ...

Scientists have discovered a clever way to turn carrot processing leftovers into a nutritious and surprisingly appealing protein. By growing edible fungi on carrot side streams, researchers produced ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers discovered that bridgmanite deep in the mantle can store far more water at high ...

Microplastics in rivers, lakes, and oceans aren’t just drifting debris—they’re constantly leaking invisible clouds of chemicals into the water. New research shows that sunlight drives this ...

Scientists have built the most detailed 3D models yet of temperatures deep beneath Greenland. The results reveal uneven heat hidden below the ice, shaped by Greenland’s ancient path over a volcanic ...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features ...

Scientists have uncovered an extensive underwater vent system near Milos, Greece, hidden along active fault lines beneath the seafloor. These geological fractures act as pathways for hot, gas-rich ...

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long assumed. While ammonia-oxidizing archaea were thought to dominate carbon ...

Researchers recreated conditions from billions of years ago and found that Earth’s young atmosphere could make key molecules linked to life. These sulfur-rich compounds, including certain amino ...

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea ...

Researchers studying Yellowstone’s depths discovered that small earthquakes can recharge underground microbial life. The quakes exposed new rock and fluids, creating bursts of chemical energy that ...

Researchers found that eroded lava rubble beneath the South Atlantic can trap enormous amounts of CO2 for tens of millions of years. These porous breccia deposits store far more carbon than ...

Rerouted shipping during Red Sea conflicts accidentally created a massive real-world experiment, letting scientists study how new low-sulfur marine fuels affect cloud formation. The sudden surge of ...

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...

A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing ...

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 ...

Scientists used CRISPR to boost the efficiency and digestibility of a fungus already known for its meatlike qualities. The modified strain grows protein far more quickly and with much less sugar ...

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 ...

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 ...
