For over a decade, confusion over the size of the proton has held scientists back. Disagreeing measurements of the subatomic particle’s radius meant that scientists couldn’t test one of their key ...

The Sun unleashes a torrent of charged particles. Some of them slam into the Earth’s atmosphere, triggering breathtaking auroras in the night sky. But for equipment that’s orbiting our planet in outer ...

Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of chemical reactions to producing highly reliable weather forecasts. For now, ...

Scientists announced on Wednesday that they have found no evidence for the hypothetical “sterile neutrino,” an extra version of the ghostly neutrino particles that are ubiquitous in the universe. The ...

Here’s what you’ll learn when you read this story: Scientists at MIT discovered a method to create a kind of particle accelerator using a molecule of radium monofluoride. Once excited by lasers in a ...

Required minimum distributions (RMDs) on tax-deferred retirement accounts begin at age 73 for individuals born between 1951 and 1959. RMDs must be completed by Dec. 31; the only exception is the first ...

What Happens During a DLS Measurement? In a DLS measurement, particles diffusing by Brownian motion scatter incident light back to a detector, where interference of the light scattered by every ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...

U.S. airlines have varying rules and guidelines related to plus-size passengers. Below, Newsweek has compared the policies of several major airlines so passengers inhabiting larger bodies can know ...
