These tropical forest CO₂ emissions may warn of similar shifts in other regions, a key topic for COP30 climate talks in Brazil.

Pricey civet coffee gets its cred from its journey through the mammal’s gut, which changes the content of fat, protein, fatty acids — and even caffeine.

The global die-off of coral reefs signals a critical shift in Earth’s climate system with global environmental consequences along with economic ones.

Antarctic krill don’t just sequester carbon in their poop; they also make carbon-rich pellets out of leftovers. But microplastics may throw a wrench in the works.

Seismic and land deformation data show that Santorini and Kolumbo draw from the same magma source, complicating eruption forecasts.

Definitively dating the age of a clutch of fossil dinosaur eggs at a famous site in China may let scientists link eggshell features to environmental shifts at the time.

Warming temperatures can ramp up the activity of methane-producing bacteria in wetland soils, adding to methane emissions.

Rising global temperatures are driving the sharp decline in terrestrial water storage. This trend isn’t likely to change, scientists say.

Researchers are still divided about whether Spinosaurus was a swimmer or a wader. What’s clear is that confirming the first swimming dinosaur would be a game-changer.

New dinosaur fossil tracks on the Isle of Skye reveal that the once-balmy environment was home to both fierce theropods and massive sauropods.
