Giant X-ray ‘chimneys’ are exhaust vents for vast energies produced at Milky Way’s center
The center of our galaxy is a frenzy of activity. A behemoth black hole—4 million times as massive as the sun—blasts out energy as...
ATLAS experiment observes light scattering off light
Light-by-light scattering is a very rare phenomenon in which two photons interact, producing another pair of photons. This process was among the earliest predictions...
The best topological conductor yet: Spiraling crystal is the key to exotic discovery
The realization of so-called topological materials—which exhibit exotic, defect-resistant properties and are expected to have applications in electronics, optics, quantum computing, and other fields—has...
Local extinction of Southern California mountain lions possible within 50 years
Two isolated mountain lion populations in southern California's Santa Ana and Santa Monica Mountains are at risk of local extinction, perhaps as soon as...
‘Terminator’-like liquid metal moves and stretches in 3-D space
In the blockbuster Terminator movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its "liquid-metal" composition....
Changes in ocean ‘conveyor belt’ foretold abrupt climate changes by four centuries
