Sending a sound upwind, against the flow of air, makes the sound louder due to an acoustical effect called convective amplification. Sound sent downwind is quieter.
A classic quantum experiment done near a black hole would create a paradox, physicists report. But not if the black hole collapses quantum states.
Tangled masses of California blackworms form over minutes but untangle in tens of milliseconds. Now scientists know how.
The atoms in a piece of sapphire oscillate in two directions at once, a mimic of the hypothetically dead-and-alive feline.
Researchers developed a leather alternative made from dormant fungus that can be reanimated and then regrow when damaged.
A proof-of-concept electronic heart tattoo relies on graphene to act as an ultrathin, flexible pacemaker. In rats, it treated an irregular heartbeat.
Real-time electron microscopy shows gold nanoparticles tumbling and sliding in a fluid before snapping together in crystalline structures.
A new and improved look at the mass of the W boson is in close alignment with theory, but it doesn’t negate an earlier, controversial measurement.
