Antimatter is not known for being easy to get ahold of. That’s part of why these particles remain so cryptic. But recently, a team of physicists at Northwestern University managed to trap a single antimatter particle for months. Cooling it to temperatures near absolute zero, they could control its quantum states with great precision without
“There are continuing problems with positive leap seconds even after 50 years, and the concern was that the negative leap second would be much more serious because its effects had never been tested,” Levine says. BIPM time department director Patrizia Tavella confirmed those concerns in an email to WIRED. “The probability of a negative leap
As part of this work, hundreds of seismometers, as well as networks of fiber-optic cables, will be used to record even the tiniest of earthquakes during periods of tranquility and unrest. This monitoring effort will be aided by machine learning programs that will be taught to identify minute shifts in the seismic soundtrack of these
Mathematician and author Steven Strogatz starts to cry when he talks about the artificial-intelligence-driven breakthroughs in his field over the past week. “The science is thrilling,” the Cornell University professor says, “but there’s a lot of human unpleasantness going with it.” On Tuesday, OpenAI said it had used tens of thousands of agents to solve
According to the standard model of cosmology, that expansion rate should be the same no matter how you measure it. But in recent years, scientists have found that the expansion rate of the early universe and that of the more recent universe vary by approximately 9 percent. That discrepancy, or tension, “has provoked heated debates
Electrons travel across the bulb to a collector plate, which creates the output current. Now, it might seem like a silly way to do that. But if we add another wire (a grid) between the filament and the collector, we can control this output current. A negative voltage on the control will push the electrons
