In 2012, a group of researchers at Tsinghua University in China created a metallic film from a mix of elements — bismuth, antimony and tellurium, with a dash of chromium to provide an effective internal magnetic field. When the Tsinghua group ran a current through the film, without any external magnetic field, the characteristic integer… Continue reading Physicists Puzzle Over Emergence of Strange Electron Aggregates

People Hate Daylight Saving. Science Tells Us Why.
In the summer of 2017, when communication professor Jeffery Gentry moved from Oklahoma to accept a position at Eastern New Mexico University, he was pleasantly surprised to find it easier to get up in the morning. The difference, he realized, was early morning light. On September mornings in Portales, New Mexico, Gentry rose with the… Continue reading People Hate Daylight Saving. Science Tells Us Why.
Hunger in Gaza Could Affect Survivors’ Health for Decades
Tanya Lewis: The situation in Gaza right now is desperate. A large percentage of the population is experiencing hunger or even dying of starvation. [Kamala Harris news clip] Tulika Bose: Videos show people using bird seed to bake “bread” or giving newborn babies dates to suck on because their mothers can’t provide enough milk. On… Continue reading Hunger in Gaza Could Affect Survivors’ Health for Decades

Medicaid Expansion Alone Won’t Stop the Opioid Overdose Crisis
Medicaid Expansion Alone Isn’t Enough to Stop the Opioid Overdose Crisis Expanding the state and federal insurance program helps prevent overdoses. But that only happens with enough treatment, and legal reform, to make it work By Hannah L. F. Cooper, Courtney R. Yarbrough, Umedjon Ibragimov, Janet Cummings & Danielle Haley People are seen outside a… Continue reading Medicaid Expansion Alone Won’t Stop the Opioid Overdose Crisis
Mathematicians Attempt to Glimpse Past the Big Bang
About 13.8 billion years ago, the entire cosmos consisted of a tiny, hot, dense ball of energy that suddenly exploded. That’s how everything began, according to the standard scientific story of the Big Bang, a theory that first took shape in the 1920s. The story has been refined over the decades, most notably in the… Continue reading Mathematicians Attempt to Glimpse Past the Big Bang
Cryptographers Discover a New Foundation for Quantum Secrecy
Ma began brainstorming how best to approach that question, together with Alex Lombardi, a cryptographer at Princeton University, and John Wright, a quantum computing researcher at the University of California, Berkeley. “It was just so fascinating and so mind-bending that I was immediately hooked,” Wright said. After thinking about the question for a while and… Continue reading Cryptographers Discover a New Foundation for Quantum Secrecy
The Simplest Math Problem Could Be Unsolvable
At first glance, the problem seems ridiculously simple. And yet experts have been searching for a solution in vain for decades. According to mathematician Jeffrey Lagarias, number theorist Shizuo Kakutani told him that during the cold war, “for about a month everybody at Yale [University] worked on it, with no result. A similar phenomenon happened… Continue reading The Simplest Math Problem Could Be Unsolvable
How to Make Hybrid Work a Success, according to Science
Certain aspects of scientific life do not lend themselves to working from home. Archaeologist Adrià Breu, who studies neolithic pottery at the Autonomous University of Barcelona, Spain, can’t dig for artefacts in his kitchen, and Claudia Sala’s experiments in molecular microbiology at the Toscana Life Sciences Foundation in Siena, Italy, oblige her to commute to… Continue reading How to Make Hybrid Work a Success, according to Science
How Japan’s ‘Moon Sniper’ Mission Hit Its Mark
When Japan’s solar-powered SLIM spacecraft made a lopsided-but-successful touchdown on the moon in mid-January, most news coverage focused on the feat as a historic first for the nation—only the fifth after the U.S., the former Soviet Union, China and India to ever achieve a soft lunar landing. But the most historic aspect of SLIM—which stands… Continue reading How Japan’s ‘Moon Sniper’ Mission Hit Its Mark
