Experiments by Soviet and American scientists last year determined that some forms of tiny invisible particles called neutrinos do have some slight mass.

The medium carrying the specific communication is a stream of particles called neutrinos that have zero rest mass and a magnetic moment 1600 times less than the magnetic moment of an electron.

Two research teams have found new evidence of transformations in elusive elementary particles called neutrinos.

Subatomic particles called neutrinos had apparently whisked underground from CERN to the Gran Sasso laboratory in Italy, 454 miles (730km) away, faster than the speed of light.

That has led to speculations of a new class of particles called sterile neutrinos.

ONE of the most important questions in physics and cosmology is whether the elusive particles called neutrinos have any mass.

One consists of "strange" and "charmed" quarks, along with particles called muons and muon neutrinos.

As the core's density increases, it becomes energetically favorable for electrons and protons to merge via inverse beta decay, producing neutrons and elementary particles called neutrinos.

Well, these little nothings called neutrinos have a lot to say, if only we could find a press willing to pass on the message.

For their research on invisible particles called neutrinos, which some scientists theorize are part of the so-called dark matter in the universe, they needed a pressurized "clean room."
