TURKU, Finland — Beam me up, Scotty! In a study that seems straight out of a “Star Trek” episode, an international team of researchers has achieved a remarkable feat in the realm of quantum teleportation. They have successfully conducted near-perfect quantum teleportation despite the presence of noise that typically...

This spring, billions of cicadas will emerge after more than a decade underground, ready to climb into the trees and make a ruckus as they sing to attract mates. But some of these insects won’t succeed in their goal of procreating — instead, they’ll be controlled like zombies into spreading a strange fungus that hijacks...

Climate change could unleash gigantic tsunamis in the Southern Ocean by triggering underwater landslides in Antarctica, a new study warns. By drilling into sediment cores hundreds of feet beneath the seafloor in Antarctica, scientists discovered that during previous periods of global warming — 3 million and 15 million years...
A UFO whistleblower has made the extraordinary claim that an alien once flagged down a military convoy to ask for a spare part. The latest in a line of UFO whistleblowers, he alleges that the US government has had dealings with extraterrestrial beings....

Is Earth Safe from a Nearby Supernova?...
Astronomers have proposed a new theory to explain the origin of phosphorus, one of the elements important for life on Earth. The theory suggests a type of stellar explosion known as “ONe novae” as a major source of phosphorus....
The search for life beyond Earth has driven seekers to scout all sorts of potential habitats — not just on the growing list of known Earth-like exoplanets, but in other places within our own solar system....
It’s 11am in Dublin and about 30 people on North Earl Street are vigorously waving at a man on an escooter in New York, who stares back at them with a look on his face that suggests he’s not entirely sure what’s going on....
Does life exist beyond Earth? One of the most compelling places to consider this possibility is Enceladus, a moon of Saturn with a liquid water ocean encased in a frozen shell. There, plumes of water spray from ice fractures into space, and spacecraft observations of these geysers suggest that Enceladus has all the chemical...
