The honor goes to a minuscule worm-like creature that lived on the seafloor 555 million years ago. Researchers led by geologists at the University of California (UC) Riverside have identified it as the first known bilaterian, an organism with a...
The ozone layer above Antarctica has recovered so much, it's actually stopped many worrying changes in the Southern Hemisphere's atmosphere. If you're looking for someone to thank, try the world at large.
The Japan Aerospace Exploration Agency's Hayabusa2 spacecraft fired a copper cannonball a little bigger than a tennis ball into a near-Earth asteroid named Ryugu to learn about its composition.
Photons captured by the immense gravity around the black hole form an intricate structure of light rings between the accretion disk and the event horizon boundary.
Nearly 60 years ago, Nobel Prize-winning physicist Nicolaas Bloembergen predicted an exciting new phenomenon called nuclear electric resonance. But no one has been able to demonstrate it in action – until now.
In pioneering research that can help explain infertility cases of unknown cause, researchers at the University of California-San Diego’s School of Medicine have discovered that an enzyme called ‘SPRK1’ leads the first step in untangling a sperm’s...
Astronomers have discovered the existence of a supermassive black hole that looks to be the oldest and most distant of its kind we've ever encountered – and it just happens to be aiming its bright particle beam directly at Earth.
What if the Earth, the galaxy, and all the galaxies near us were enclosed in a weirdly empty bubble? This scenario could resolve some longstanding questions about the nature of the universe.
The researchers weren’t looking for the new particle, though. Instead, it popped up as an anomaly in their detector back in 2015 while they were searching for signs of dark matter. The oddity didn’t draw much attention at first. But eventually, a...
Scientists have discovered an animal that does not need oxygen to produce energy needed for its survival, a finding that changes one of science's assumptions about the animal world.
