Debate grows over whether X-rays are a sign of dark matter
The dwarf galaxy Draco, which is chock-full of dark matter, doesn’t emit a band of X-rays that researchers hoped were produced by the mysterious invisible stuff.

Bright minds, antineutrinos and more reader feedback
In the November 28, 2015, issue of Science News, readers discussed humanizing science, frog mating calls, antineurtrinos and Martian dust storms.

Antiprotons match protons in response to strong nuclear force
The first study of how antiprotons interact with each other reveals yet again that particles of antimatter behave just like their ordinary matter counterparts.

Neutrinos’ identity shift snares physics Nobel
Arthur McDonald and Takaaki Kajita shared the 2015 Nobel Prize in physics for the discovery that neutrinos oscillate between different types, which demonstrates that the particles have mass.

Map captures Earth’s antineutrino glow
Tiny subatomic particles called antineutrinos stream away from Earth at different concentrations across the globe, a new map illustrates.

Antimatter doesn’t differ from charge-mass expectations
An experiment with unprecedented precision finds that protons and antiprotons have the same ratio of charge to mass, which is consistent with theories but disappoints many physicists.

Elusive particle shows up in ‘semimetal’
Weyl fermions, which resemble massless electrons, have been spotted inside tantalum arsenide. Their discovery comes 86 years after they were proposed.
