Thawing permafrost helped trigger ancient Icelandic landslides, new research shows
When glaciers and ice sheets melt, they can destabilize slopes and reactivate faults, which in turn can trigger landslides and reshape the surface of Earth over long periods of time. Researchers can monitor some locations in real time to determine which combinations of factors lead to landslides, but understanding what triggered landslides thousands of years ago is more difficult.

Swarm detects ocean tides' magnetic signatures
A study using data from ESA's Swarm mission suggests that faint magnetic signatures created by Earth's tides can help us determine magma distribution under the seabed and could even give us insights into long-term trends in global ocean temperatures and salinity.

Simulations clarify the mechanism of coupled plasma fluctuations
In nature, phenomena in which multiple fluctuations occur in a coupled manner are frequently observed. For example, in large earthquakes, cases of them occurring consecutively in adjacent regions have been reported. When multiple fluctuations occur in this coupled way, compared to a single fluctuation, the coupled ones release more energy, leading to larger-scale phenomena.

Seismic study reveals ancient 'islands' deep within Earth's mantle
Deeply hidden in Earth's mantle there are two huge "islands" the size of a continent. New research from Utrecht University shows that these regions are not only hotter than the surrounding graveyard of cold sunken tectonic plates, but also that they must be ancient: at least half a billion years old, perhaps even older.

The economy was the big issue for youth in 2024—especially for those who didn't vote
Economic concerns motivated many voters to go to the polls in 2024, but they were even bigger priorities for young Americans who did not vote, according to a new poll conducted by the Center for Information & Research on Civic Learning and Engagement (CIRCLE) at Tufts University's Jonathan M. Tisch College of Civic Life.

Astronauts set to swab the exterior of station for microbial life
Astronauts are scheduled to venture outside the International Space Station to collect microbiological samples during crew spacewalks for the ISS External Microorganisms experiment. This investigation focuses on sampling at sites near life support system vents to examine whether the spacecraft releases microorganisms, how many, and how far they may travel.
