Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...

The holy grail of every particle physics experiment is the discovery of a new particle. Finding a new constituent of matter may earn you eternal glory within the history of physics. Unfortunately, ...

Physicists have announced the observation of a new particle, the Omega-sub-b (Ω b). The particle contains three quarks -- two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the ...

In the course of exploring the properties of a strange subatomic particle, physicists may have stumbled upon something even stranger: a mysterious and exotic new form of matter. The intriguing ...

A single subatomic particle detected at the South Pole last September is helping to solve a major cosmic mystery: what creates electrically charged cosmic rays, the most energetic particles in nature.

Two teams of physicists have stumbled across a weird new subatomic particle that’s unlike anything else we’ve ever seen—and it could rewrite the rules of matter as we know them. Researchers from both ...

If you were able to shrink yourself to the size of a subatomic particle, the world would look very different. You’d find yourself floating in what appeared to be outer space, and objects which are ...

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 ...

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 ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...
