Earth is bathed in droves of neutrinos spewed by the Milky Way’s stars
The Milky Way could be called “the Neutrino Way.” Its stars produce vast numbers of the subatomic particles. Now, scientists have calculated how many of them should be…
Physicists discovered neutrinos 70 years ago. The ghostly particles still have secrets to tell
Neutrinos have been with us since the beginning. They existed alongside prehistoric humans, dinosaurs and the first scattered crumbs of life on Earth. The birth of the solar…
The only U.S. particle collider shuts down – so a new one may rise
I peeked in on the house-sized particle detector known as STAR just after it took its last-ever snapshot of one of the most extreme types of fireball ever…
Antimatter traveled by truck for the first time
Special delivery: antimatter. Scientists have completed the first-ever transport of antimatter by truck. On March 24, researchers carried antiprotons, the negatively charged counterparts of protons, inside a magnetic…
World’s first superconducting quantum heat engine could help unlock massive quantum computers

Tiny graphene wrinkles create surprisingly powerful electrical effects
Rice University researchers have shown that tiny wrinkles in graphene can change the material’s electrical properties. Credit: Ajayan lab/Rice University Researchers at Rice University have found that extremely…
Caltech breakthrough brings fiber-optic performance to silicon chips
Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the…
