A new way to chill out is simple: Just unwind. Called twistocaloric cooling, the method involves unwinding tightly twisted strands of various materials. The technique was used to chill water by several degrees Celsius, scientists report in the Oct. 11 Science. Cooling techniques like those used in traditional refrigerators rely on cycles of compressing and […] More
Two sets of cosmic discoveries have garnered the 2019 Nobel Prize in physics. Half of the prize of 9 million Swedish kronor (about $900,000) goes to James Peebles of Princeton University, who discovered new theoretical tools to study the universe. His research includes studies of the cosmic microwave background, or CMB, light emitted early in […] More
The Number of the HeavensTom SiegfriedHarvard Univ., $29.95 There is no bigger question than whether the universe is all there is. Scientists are juggling several ideas for what a multiverse, if one exists, might be like. Our universe could be one bubble in a vast cosmic fizz. Or one of many 3-D domains stacked, like […] More
After nearly four years of painstaking work, in 1902 Marie Curie produced one-tenth of a gram of radium chloride from several tons of uranium ore. It took her another eight years to isolate pure radium. The effort won her a second Nobel Prize and cemented her legacy as one of science’s most tenacious minds. “One […] More
Speaking with Andrea Young feels like watching a racehorse holding itself back at the starting gate. We met on the campus of the University of California, Santa Barbara, where he’s a condensed matter physicist, to chat about his work on 2-D materials. His mind seems to be working faster than the conversation can flow. My […] More
“I like it if I can run uphill and be rewarded with a view of the bay,” says Monika Schleier-Smith. She’s talking about a favorite spot to exercise around Palo Alto, Calif., but the sentiment also applies to her scientific work. A physicist at Stanford, Schleier-Smith, 36, has a reputation for embracing the uphill climb. […] More
Polar caps quickly losing ice. Chalky coral reefs. Stronger storms that devastate islands and cities, claiming lives and destroying homes. Those aren’t speculations about what our world faces in a warmer future. Those are climate change impacts happening now — and set to worsen, according to a new report by the U.N. Intergovernmental Panel on […] More
Something Deeply HiddenSean CarrollDutton, $29 Quantum physics is about multiplicity. Its equations describe multiple possible outcomes for a measurement in the subatomic realm. Physicists have devised a dozen or two different interpretations of what that really means. And in turn, dozens and dozens of books have been written to explain, defend or deny the validity […] More
