Dune leapfrogging is deciphered
Some wind-propelled sand dunes can pass right through each other if their relative sizes are right, new computer simulations indicate—although the sand grains of one dune don't actually penetrate through the other dune.

Hints emerge of a four-quark particle
Previously observed only in twos, threes, and perhaps in fives, quarks and antiquarks in a newfound particle may have glommed together to form a never-before-seen foursome.

Doppler Toppler: Experiment upends normal frequency shift
The expected drop in frequency of a signal from a receding source—the Doppler effect—becomes a frequency increase when a high-current electric pulse creates extraordinary electromagnetic conditions in a web of electrical components.
