Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features that point to the birth of an ultra-dense, rapidly spinning magnetar. The paper outlining this finding was published in The Astrophysical Journal Letters on July 22.
The strongest glasses have an Achilles' heel that causes them to fail catastrophically when pushed past their limit. They do not bend or stretch, as all damage concentrates into a single plane and the material fails in an instant. This brittleness has long capped the usefulness of high-stability amorphous solids, from bulk metallic glasses to engineered metamaterials.
Employers are increasingly investing in training to prepare their employees for artificial intelligence (AI). Training budgets are growing, and "upskilling" has become a common response to rapid technological change.
Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary matter and electromagnetic fields; hence, they would be difficult to detect in conventional particle physics experiments.
Astronomers at MIT and elsewhere have spotted an extremely bright red spot in the early universe. The object resembles an enormous star, roughly the size of our solar system. But it also is putting out 100 billion times more energy than any known star can physically produce. In fact, such energies are closer to what a black hole might generate.
