Gluons are the quantum ‘Gorilla Glue’ involved in binding quarks together, ScienceAlert reminds us. But for nearly 50 years, physicists have hunted for “glueballs”, exotic particles predicted by this theory of the strong interaction — the only type of particle in nature composed entirely of force mediators: Now, a collaboration Read more…
A Pew Research senior data scientist analyzed 500,000 English-language webpages from the past five years with an AI detection tool to estimate how many were likely written or edited by AI: Of all the pages in this sample, 10% show significant signs of AI authorship… If we filter old webpages Read more…
It’s radically different from other quantum computers. The Helios system uses trapped ions — charged atoms suspended in free space using electromagnetic fields. But it operates with 98 qubits — making it the largest trapped-ion quantum computer built so far. Quantinuum, the company behind the device, is based in Cambridge, Read more…
“There is still no sign of economy-wide job destruction,” says economist Erik Brynjolfsson. Working with researchers at the Stanford Digital Economy Lab, Brynjolfsson has determined an AI “job apocalypse” is unlikely even though it will likely impact entry-level jobs. And Brynjolfsson “predicts that demand for experienced workers such as senior Read more…
AI went from being very terrible to seemingly genuinely quite good at a professional level in a very short space of time… But AI systems are still truly, truly terrible at some areas of math… even the days of the week. If you look at academic math papers, a lot Read more…
