Watch Now: Einstein's Scientific Revolution and the Limits of Quantum Theory
Cosmologist Lee Smolin says that at certain key points, the scientific worldview is based on fallacious reasoning
How Long Do Neutrons Live? Physicists Close In on Decades-Old Puzzle
Researchers are narrowing down their measurements of how long the subatomic particle survives on its own
Squeezed Potassium Atoms Straddle Liquid and Solid
At extreme pressures, potassium atoms can be both liquid and solid at the same time, a phase of matter known as "chain melt." Christopher Intagliata reports.
Infrared Light Offers a Cooler Way to Defrost
Light tuned to a specific frequency warms ice more than water—which could come in handy for defrosting delicate biological samples. Adam Levy reports.
All Mixed Up? Discover the Brazil Nut Effect

Watch Now: Gravitational Waves as New Windows on the Universe
Astrophysicist Chad Hanna discusses how ripples in spacetime are revolutionizing our understanding of the cosmos
Gravitational-Wave Hunt Restarts--with a Quantum Boost
Detailed data on space-time ripples are set to pour in from LIGO and Virgo’s upgraded detectors
Quantum Gravity in the Lab
Physicists attempting to unify the theories of gravity and quantum mechanics have long thought practical experiments were out of reach, but new proposals offer a chance to test the quantum nature of gravity on a tabletop...
Found: A Quadrillion Ways for String Theory to Make Our Universe
Stemming from the “F-theory” branch of string theory, each solution replicates key features of the standard model of particle physics
Russia's New Nuclear Missiles Squeeze Response Time
As treaties end, Russia focuses on hypersonic weapons that could “tighten the noose” on current U.S. defenses
An Impossible Scenario: Scientists Watch as Heat Moves at the Speed of Sound
A rare phenomenon seen in just a handful of materials at forbidding temperatures has been detected within “warm” graphite—a finding that could aid future microelectronics...

Atheism Is Inconsistent with the Scientific Method, Prizewinning Physicist Says
In conversation, the 2019 Templeton Prize winner does not pull punches on the limits of science, the value of humility and the irrationality of nonbelief
Soap-Bubble Pioneer Is First Woman to Win Prestigious Math Prize
Abel-prize winner Karen Keskulla Uhlenbeck built bridges between analysis, geometry and physics
Solar Jets Cause Standing Waves in Earth's Magnetic Field
When jets of charged particles from the sun hit our magnetosphere, some of the ensuing ripples travel toward the northern and southern poles and get reflected back. The resulting interference allows standing waves to form, like on a drumhead...

Would New Physics Colliders Make Big Discoveries or Wander a Particle Desert?
Around the globe, imminent decisions on proposed next-generation experiments are set to shape particle physics for decades to come
Busting Earth-Bound Asteroids a Bigger Job Than We Thought
A new model suggests smashing killer space rocks with insufficient force could let gravity pull the pieces back together. Christopher Intagliata reports.
