Atmospheric circulation governs weather and climate, but it also carries angular momentum. When winds shift or mass redistributes, the atmosphere can exchange momentum with the solid Earth, slightly altering the planet's ...

On July 29, 2025, at 23:24 Universal Time, a long stretch of seafloor off Russia's Kamchatka Peninsula was thrust upward. The magnitude 8.8 earthquake was the largest on Earth since the Tohoku earthquake of 2011, according ...

At the southwest tip of Sweden, the Falsterbo Peninsula stretches into the Baltic Sea, creating a natural bottleneck for hundreds of millions of birds traveling south for the winter each year. Falsterbo is particularly known ...

Slaughterhouses are places most people never want to go, and might seem like unlikely places to search for rare or endangered species. In West Africa, however, they are among the last places one can find a critically endangered ...

Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made of. Black holes ring too. When two merge, the newborn black hole shivers and sheds gravitational ...

A drop of coffee on a tabletop often leaves a dark ring behind. This everyday mark is a reminder that a drying droplet is not passive: As water evaporates, it can transport the particles suspended inside it toward the edge. ...

Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot ...

Cancer is most dangerous not when it starts but when it spreads. Metastasis—the process by which cancer cells travel to and colonize distant organs—is responsible for the vast majority of cancer deaths. The problem is that ...

Have you ever wondered what Earth observation satellites see when they look down at the deep ocean or a dense tropical forest during the dead of night? The answer, for the most part, is nothing. Standard optical sensors require ...

How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ultrafast motion of atoms to the slow deformations measured in a laboratory? This is a deceptively difficult ...

For years, I have been interested in disorders in which patients experience very real symptoms even though conventional brain imaging may look normal. Molecular imaging has taught me a simple lesson: what is invisible anatomically ...

We usually think of auroras as beautiful lights in the night sky. I see them as visible traces of a connection between the sun, Earth's magnetic field and the atmosphere. This led me to an origin-of-life question: Could the ...
