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. Deeply hidden…
In the world of modern optics, frequency combs are invaluable tools. These devices act as rulers for measuring light, enabling breakthroughs in telecommunications, environmental monitoring, and even astrophysics. But building compact and efficient frequency combs has been a challenge—until now. In the world of modern optics, frequency combs are invaluable tools. These devices act as rulers…
A double layer of tungsten diselenide behaves as a superconductor at very low temperatures, which could suggest a new route to developing materials that do so at room temperature A double layer of tungsten diselenide behaves as a superconductor at very low temperatures, which could suggest a new route to developing materials that do so at…
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. In nature,…
Scientists have detected cosmic waves that sound like chirping birds in an unexpected place. These bursts of plasma, called chorus waves, ripple at the same frequency as human hearing. When converted to audio signals, their sharp notes mimic bird calls. Now researchers have sensed the chirping waves farther away: over 62,000 miles from Earth. The…

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. Economic concerns…
Companies in the United States are turning to voluntary earnings guidance to prevent confusion resulting from environmental, social and governance (ESG) disclosures, according to a new study from researchers at Florida Atlantic University and the University of Vassa in Finland.

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. Astronauts are scheduled to venture outside…
