A new Caltech device can redirect a beam of light in just 74 femtoseconds using another beam and a nanoscale silicon metasurface. The breakthrough could pave the way for dramatically faster photonic ...

Scientists have found a new way to create a controlled beam of muonium, an exotic atom containing a heavier cousin of the electron. The advance could allow researchers to test for the first time ...

Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant ...

A natural compound produced by gut bacteria after digesting foods such as pomegranates, walnuts, and berries may help repair ...

A pocket-sized, roughly $100 detector can reveal the invisible stream of cosmic particles constantly passing through Earth ...

NASA’s Roman Space Telescope may now have enough fuel for at least 22 years of science, more than double its original 10 year design life. An extremely precise course correction, extra fuel at launch, ...

Astronomers have confirmed a Jupiter-size planet less than a million years old, making Elias 2-24 b the youngest known planet and giving scientists a rare look at a world still being born. Its ...

A kimchi-derived bacterium can bind to nanoplastics under gut-like conditions and may help carry them out of the body. In mice, the probiotic more than doubled the amount of nanoplastics detected in ...

Scientists discovered a new frog species in the flooded forests of the western Amazon, distinguishing it from nearly identical relatives through DNA and its unique call. Adenomera varcena highlights ...

Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring ...

Anak Krakatau erupted for more than 24 hours in early September, sending volcanic ash up to 50,000 feet into the atmosphere. The ash cloud shut down eight airports, disrupted nearly 3,000 flights, and ...

Arctic sea ice may move in unexpected ways because individual ice floes are constantly colliding and transferring energy. Researchers found that this simple process can explain several long-standing ...
