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

The CMS and ATLAS experiments at the Large Hadron Collider joined forces to make the most precise measurement of the mass of the Higgs boson yet. On the dawn of the Large Hadron Collider restart, the ...

An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino. The neutrino could be the weirdest ...

NEWPORT NEWS, VA – Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy’s Thomas ...

Negative mass is a hypothetical concept that says matter can exist with a mass opposite to normal matter. Instead of having a positive weight—1kg, for example—negative mass would weigh minus 1kg. This ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly ...

Researchers have found that bone and muscle mass are regulated by the altered gravity. The experiments were done in space using Kibo, an ISS module developed by JAXA, and on the ground. An ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...
