New theory defines faster MRI
Better equations could improve MRI quality, or even bring quantum computing closer.

Standard model gets right answer for proton, neutron masses
Correct calculation strengthens theory of quark-gluon interactions in nuclear particles.

Superconductivity does the twist
Electron fluctuations could explain why exotic material conducts without resistance.
- Space
Misplaced muons either mundane or monumental
During an experiment in Fermilab's Tevatron particle accelerator, a group of elementary particles called muons showed up in a strange place. Physicists are considering the likely implications.

Take the time to break quantum encryption
A time-travel scenario permitted by Einstein’s general theory of relativity offers a bit of possibility for breaking quantum encryption.

Blueprint to repel oil and water
The texture of surfaces could be designed so that both water and oil can bead up and thus flow off.
- Space
Half-life (more or less)
Physicists are stirred by claims that the sun may change what’s unchangeable—the rate of radioactive decay.
