Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced ...

A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star. It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded. The results suggest ...

A person's sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected "brain age" was tied to a ...

Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus. The breakthrough could improve models of how stars, supernovae, and neutron star mergers create heavy elements.

Engineers have transformed a notoriously brittle cobalt-aluminum compound into a material that is both extremely strong and capable of bending without breaking. Their nanoscale design produced a yield strength about six to 10 times greater than high ...

Physicists have uncovered a surprising limit to electrical resistance caused by particles colliding. Using ultracold potassium atoms trapped in a grid of light, researchers created a highly controlled stand-in for electrons moving through a solid. As ...

Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ALMA telescope in Chile, researchers conducted .. ...

Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second. Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry.

Rice University chemists have found a new way to make neodymium, a rare-earth metal, interact with oxygen. Using a specially designed molecular structure described as a "basket," the team positioned the atoms so they could form a bond once thought .. ...

Europa's hidden ocean has made the icy moon one of the solar system's most promising places to search for habitable conditions. Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future .. ...
