Wormholes are a sci-fi staple, and and it's possible that they exist in the real universe. But how would they work? Physicists have now used a quantum processor to simulate a traversable wormhole, teleporting information between two quantum systems.

If you’ve ever found room for dessert when you thought you were full, your gut bacteria might be to blame. Caltech scientists have shown that mice given antibiotics ate far more sugary snacks, hinting at a bacterial influence on overeating.

Caltech's wildly ambitious space solar project, buoyed by a massive hundred-million-dollar donation, is preparing to launch its first prototypes into orbit. These cutting-edge ultralight structures will collect, convert and wirelessly send energy.

Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful.

Researchers at Caltech are reporting preclinical success with a universal coronavirus vaccine. The vaccine uses mosaic nanoparticle technology to protect not only against SARS-CoV-2 but also the original SARS, and several common cold coronaviruses.

The hunt for planets beyond our solar system has now reached a major milestone. A new batch of 65 exoplanets brings the total number of confirmed planets beyond our solar system to over 5,000 – with potentially hundreds of billions left to find.

SpaceX's aspirations to blanket the Earth in high-speed internet through a constellation of orbiting satellites continues apace, and a new study demonstrates the significant mark they are already making on the world of astronomical imaging.

Is there microbial life floating around in the clouds of Venus? Scientists have long pondered this question and soon we may get some answers, starting with a cloud-skimming mission in 2023 to search for signs of life.

Whether you think it’s cool or unnerving, robots are becoming more agile – and Caltech’s LEONARDO looks like one of the most nimble examples yet. LEO walks on two legs, jumps and flies, can balance on a slackline and even skateboard.

Astronomers have spotted a new type of supernova for the first time. An unlucky star seems to have prematurely exploded after colliding with an extremely dense object, perhaps a black hole or a neutron star, creating a unique signature in the sky.

A new example of a material with shape-shifting capabilities is modeled on ancient chain mail armor, enabling it to swiftly switch from flexible to stiff thanks to carefully arranged interlocking particles.

A new study has highlighted the gut-brain link between social behavior and gut microbes in mice, showing how a lack of certain gut bacteria can increase levels of a hormone that activates a part of the brain that contributes to antisocial activities.
