UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In one, a hidden “mirror” universe with its own particles and forces could have created dense black hole–like objects in the early cosmos, making […]

Scientists have designed swarms of microscopic robots that communicate and coordinate using sound waves, much like bees or birds. These self-organizing micromachines can adapt to their surroundings, reform if damaged, and potentially undertake complex tasks such as cleaning polluted areas, delivering targeted medical treatments, or exploring hazardous environments.

AI is now a routine part of workplace communication, with most professionals using tools like ChatGPT and Gemini. A study of over 1,000 professionals shows that while AI makes managers’ messages more polished, heavy reliance can damage trust. Employees tend to accept low-level AI help, such as grammar fixes, but become skeptical when supervisors use

Hubble’s latest portrait of the Tarantula Nebula reveals a turbulent star-making region far beyond the Milky Way. Located 160,000 light-years away in the Large Magellanic Cloud, this cosmic expanse is home to some of the most massive stars ever discovered—up to 200 times the Sun’s mass. The image captures intricate dust clouds, intense stellar winds

NASA’s Lunar Trailblazer, a mission designed to create high-resolution maps of water on the Moon, ended after losing contact with the spacecraft just one day after its February 26 launch. Despite extensive global efforts to reestablish communication, the small satellite’s misaligned solar arrays prevented its batteries from charging, leaving it powerless and drifting in a

Scientists at SLAC unexpectedly created gold hydride, a compound of gold and hydrogen, while studying diamond formation under extreme pressure and heat. This discovery challenges gold’s reputation as a chemically unreactive metal and opens doors to studying dense hydrogen, which could help us understand planetary interiors and fusion processes. The results also suggest that extreme

At the Large Hadron Collider, scientists from the University of Kansas achieved a fleeting form of modern-day alchemy — turning lead into gold for just a fraction of a second. Using ultra-peripheral collisions, where ions nearly miss but interact through powerful photon exchanges, they managed to knock protons out of nuclei, creating new, short-lived elements.

Physicists have heated gold to over 19,000 Kelvin, more than 14 times its melting point, without melting it, smashing the long-standing “entropy catastrophe” limit. Using an ultra-fast laser pulse at SLAC’s Linac Coherent Light Source, they kept the gold crystalline at extreme heat, opening new frontiers in high-energy-density physics, fusion research, and planetary science.

Scientists have found that microscopic gold clusters can act like the world’s most accurate quantum systems, while being far easier to scale up. With tunable spin properties and mass production potential, they could transform quantum computing and sensing.

Using the world’s most powerful X-ray laser, researchers have captured the hidden, never-ending vibrations of atoms inside molecules. This first-ever direct view of zero-point motion reveals that atoms move in precise, synchronized patterns, even in their lowest energy state.
