A subatomic particle called the W boson may be heavier than expected, a surprising finding that might lead to a shake-up of physics' grand model of how the world works on the microscale. When you ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Here’s what you’ll learn when you read this story: Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

When it comes to talent, versatility and the power to change the world, which atomic particle is the champ? Read what our four contenders have to say—then you decide. Physics fans, are you ready to ...

Modern scientists face several pressing mysteries in their quest to understand the laws of the universe. A recent discovery could represent a very substantial step forward in solving a couple of them.

A pair of physicists announced the discovery of a subatomic event so powerful that the researchers wondered if it was too dangerous to make public. The explosive event? The duo showed that two tiny ...

The Chinese city of Xi’an has a deep, rich history. Remains from Lantian Man, belonging to the species Homo erectus, were discovered in the 20th century and dates to about 710,000 years ago, which is ...

New research suggests reported decays of a Kaon by the Koto experiment may actually be new particles. Florida State University physicists believe they have an answer to unusual incidents of rare decay ...
