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.

Tree trunks in the Amazon are getting 3.3% thicker every decade as the plants absorb extra carbon dioxide, suggesting they are more resilient to global warming than previously thought.

Researchers have described a whole new family of extinct crocodyliforms based on the fossilized remains of a single teenage croc named Elton discovered in the Blackleaf Formation.

Data from ESA's Cryosat-2 satellite has revealed 85 never-before-seen, active subglacial lakes buried beneath Antarctica's ice — 58% more than were previously known.

Less than 400 angle-stemmed myrtle specimens remain in the wild in Australia. Scientists are working on ways to preserve the species so that we can bring it back at any point if it dies out.

Archaeologists in Jerusalem have discovered a 2,270-year-old gold coin with Queen Berenice II of Egypt and the inscription "of the Queen," suggesting she was a powerful and influential monarch.

Weather predictions show that Hurricane Kiko could hit Hawaii next week, but forecasters say the Category 4 storm will weaken to a tropical storm or low-category hurricane this weekend.

The Atlantic Meridional Overturning Circulation brings heat to the Northern Hemisphere and regulates the climate globally, but research suggests it could weaken significantly in the coming decades.

A giant iceberg called A23a that broke off Antarctica in 1986 is now disintegrating near South Georgia Island in the South Atlantic Ocean, scientists say.

Japanese government officials have released an AI video to show just how devastating an eruption at Mount Fuji could be. But don't worry, the dormant volcano is currently not at risk of blowing.

A 100-year-old theory explaining how Asia can carry the huge weight of the Himalayas and Tibetan Plateau needs to be rewritten, a new study suggests.
