Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle’s glow signals each step in its changing ...

Here’s what you’ll learn when you read this story: It used to be thought that bizarre interactions between subatomic particles known as neutrinos could be explained by another type of neutrino. The ...

They used a nanoscale particle made of glass levitated in a vacuum and cooled it to the lowest possible energy level to reduce its uncertainty. After making sure its trapping potential was optimally ...
