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 . ...

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 ...

Some black holes roaming the Universe today may actually be older than the Big Bang. A new cosmic "bounce" model suggests the Universe expanded from an earlier contracting phase, allowing ancient black holes to survive the transition as cosmic ...

NASA is assembling the foundations of a future Moon Base through a wave of robotic missions and powerful new commercial landers. More than 20 landings are planned through 2029, testing everything from precision landings and lunar communications to .. ...

Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable smarter catalyst designs that boost clean power ...

A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views. ESA will livestream the spectacle from the Javalambre Observatory, combining telescope feeds, drone footage, and expert .. ...

NASA engineers have found a clever way to squeeze more life out of Voyager 2, nearly half a century after it left Earth. In an operation nicknamed the "Big Bang," the team simultaneously shut down certain power-hungry hardware and switched to lower . ...

Cassini data has revealed a surprising twist in Saturn's magnetic shield: the planet's rapid rotation appears to drag a key opening in its magnetosphere far toward the afternoon side instead of keeping it near noon, as happens on Earth. The finding . ...

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 ...

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 ...
