Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn't expanding wildly fast. The study suggests that the very shape of space-time may protect the ...

Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe's biggest galaxies seem to have far fewer stars than expected. Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found ...

The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power. Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth. Yet space ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this cosmic memory could help solve some of the biggest puzzles in physics, from black holes to dark matter and the universe's ultimate ...

A clever nanoscale redesign may have solved one of superconductivity's biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at . ...

A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials. Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much ...

Physicists have solved a long-standing problem involving systems that appear to violate Newton's third law, such as bird flocks and bacterial swarms. By adding carefully designed "imaginary partners" to their models, they can now simulate these ...

Researchers discovered that hydrogen radicals generated by intense UV light can break down stubborn PFAS "forever chemicals" without added chemicals. The breakthrough reveals a key mechanism that could lead to greener and more effective technologies ...

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio ...

Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world. Researchers say the answer isn't to stop following current events--it's to build healthier habits .. ...
