It's not every day that someone comes across a new state of matter in quantum physics, the scientific field devoted to describing the behaviour of atomic and subatomic particles in order to elucidate their properties.
Yet this is exactly what has been done by an international team of researchers that includes Andrea Bianchi, University of Montreal physics professor and researcher at the Regroupement québécois sur les matériaux de pointe, and his students Avner Fitterman and...
There has been a sustained cyber-conflict over Ukraine that could still escalate, a senior U.S. intelligence official has told the BBC.
Despite warnings, major cyber-attacks on the West have so far not materialized.
But Russia should not be underestimated, said Rob Joyce, director of cyber-security at the National Security Agency.
Meanwhile, independent hackers targeting Russia in support of Ukraine could also spark escalation, he warned.
"I'm still very worried about the threats emanating from around the Russia-Ukraine situation,"...

Overall evidence to date on whether eating dairy products affects the risk of cancer has been inconsistent. Studies on western populations indicate that dairy products may be associated with a lower risk of colorectal cancer and a higher risk of prostate cancer, but have found no clear link for breast or other types of cancer. These results, however, may not be the same for non-western populations, where amounts and types of dairy consumption and...
Whether you need a new villain or an old Spider-Man, your sci-fi movie will sound more scientifically respectable if you use the word "multiverse." The Marvel multiverse puts different versions of our universe "out there," somewhere. In these films, with the right blend of technology, magic, and imagination, travel between these universes is possible, writes Luke Barnes in The Conversation.
For example (spoilers!), in "Spider-Man: No Way Home," we discover there are other universes and...
The U.S. provided intelligence that helped Ukraine sink the Moskva, Russia's flagship Black Sea missile cruiser, several media outlets report.

Argentine paleontologists have announced the discovery of an apex-predator dinosaur that measured three storeys from nose to tail and eviscerated its prey with sharp, curved claws, Phys.org reports.
The six-ton giant, the largest megaraptor unearthed to date, fed on smaller dinosaurs that it ripped to shreds with its talons before digging into their intestines, paleontologist Mauro Aranciaga told AFP.
It would have been the "apex predator" of its time, said Aranciaga – well deserving of its...
A Texas law forbidding social media giants from regulating certain forms of online speech has been blocked by the U.S. Supreme Court.
The legislation would have prevented larger tech companies from banning or censoring Texas users for their views.
Republicans in the state said it was necessary to combat what they claimed was social media's liberal bias.
But tech groups argued that the law was a violation of the private companies' freedom of speech rights.
In a rare...
