James Webb has captured a striking new infrared view of NGC 2392, the Lion Nebula, revealing the dramatic aftermath of a dying Sun-like star. At its center, a scorching white dwarf is blasting

Scientists have created an unusually corrosion-resistant stainless steel that could replace costly titanium components used to produce green hydrogen. The breakthrough could reduce structural material costs by roughly 40 times and make seawater-based

Ordinary WiFi networks could quietly become powerful surveillance tools, allowing people to be identified without cameras, special sensors, or even carrying a connected device. Researchers showed that unencrypted signals routinely exchanged between WiFi

Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that

Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide. These previously invisible vortices may twist magnetic fields and help build up the energy released in

A rare meteorite that crashed through a New Jersey roof contains evidence of ancient salty fluids, organic compounds, and amino acids from a primitive asteroid. Its pristine chemistry could offer new clues about

A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more practical way to power
