Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Space scientists seeking to understand the enigmatic origins of powerful cosmic rays have detected an extremely rare, ultra-high-energy particle that they believe traveled to Earth from beyond the ...

A deep-sea neutrino telescope has detected the most energetic neutrino ever recorded. The particle, known as a "ghost particle," was about 30 times more active than the previous record-holder.

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally ...

Illustration of an array of ground-based detectors to characterize a cosmic ray shower. When high-energy cosmic particles strike the atmosphere, they produce a cascade of particles. By building a ...

Nuclear and particle physics, almost synonymous with high-energy physics, is an important subfield of experimental physics. A wide range of studies in this domain are classified as scattering ...

The ancient Greeks conceived of five building blocks of matter – from bottom to top: earth, water, air, fire and aether. Aether was the matter that filled the heavens and explained the rotation of the ...

Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them. In the 1930s, the French physicist Pierre ...
