Researchers used artificial intelligence to analyze more than 3,000 recordings of African lions and found that the animals have an "intermediate" roar as well as a "full-throated" roar.

Researchers thought that Axial Seamount might erupt in 2025, but recent data suggest the underwater volcano could take a bit longer to blow its top.

Researchers have documented the strange antics of two tropical spider species that build giant, arachnid-shaped decoys out of silk, plant matter and prey remains in their webs.

Ancient supercontinent Nuna's breakup around 1.5 billion years ago set off a chain of events that made Earth more habitable, new research suggests.

Scientists with the Norwegian Orca Survey and Orca Channel have documented, for the first time and in astounding detail, the birth of an orca and the newborn's first hour.

The UNEP's 2025 Emissions Gap report has found that global average temperatures will exceed 1.5 C (2.7 F) before 2035 — and this just days before the COP30 climate summit kicks off in Brazil.

A giant colonial spiderweb in a sulfuric cave on the border between Greece and Albania may be the largest ever found — and it was built by spiders we didn't know liked the company of others.

An orca pod that made headlines last year for gutting a whale shark has struck again, this time perfecting a technique that involves paralyzing young great white sharks to eat their livers.

Researchers have gained new insights into rhinoceros evolution and the longevity of the North Atlantic Land Bridge from analyzing the perfectly preserved fossils of a "frosty" Arctic rhino.

Earth's mantle is so gooey, it takes eons for material that has been displaced by the weight of ice sheets to flow back. And Greenland is very much still processing its glacial past, a new study shows.

Earth's systems are nearing tipping points that could plunge the planet into a "hothouse" regime — but there's still time to prevent that from happening, scientists say.

Tropical Storm Melissa is moving at a snail's pace but will intensify rapidly over the weekend as it feeds off near-record-warm water temperatures in the Caribbean Sea, forecasters say.

Experts at a laboratory in Botswana managed by the Gemological Institute of America recently examined an extraordinary natural diamond with two distinct color zones.

In a first, researchers have discovered fragments of Earth's precursor that contain distinctive chemical fingerprints in ancient rocks from Greenland, Canada and Hawaii.

Researchers analyzed changes over time in the ratio of small earthquakes to bigger ones beneath Mount Etna and found a strong correlation with the volcano's activity over the past 20 years.

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in the direction of Africa over the past decade.

A new AI tool reveals that Campi Flegrei experienced more than 54,000 earthquakes between 2022 and 2025. By mapping these events, researchers discovered a huge, crisp, ring-shaped fault.

Researchers incubated permafrost samples from Alaska at different temperatures and found that microbes from the last ice age can reactivate and resume breaking down carbon.

Rising levels of CO2 in the atmosphere may trigger a series of geological and biological processes that could ensure the next ice age arrives on time instead of being delayed, researchers say.

An analysis of clam shells suggests the North Atlantic subpolar gyre has had two periods of destabilization over the past 150 years: one around 1920 and the other from 1950 through present.

The number of deaths from exposure to wildfire smoke in the U.S. could rise by more than 70% in the next 25 years. The human and economic costs involved would be astronomical, researchers say.
