The sound of an atom has been captured
Researchers at Chalmers University of Technology are first to show the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on ...
Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
What does a supernova sounds like?
We've all been ruined by science fiction, with their sound effects in space. But if you could watch a supernova detonate from a safe distance away, what would you hear?
Ultracold Big Bang experiment successfully simulates evolution of early universe
(Phys.org) —Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the ...
Engineers build first nonreciprocal acoustic circulator: A one-way sound device
A team of researchers at The University of Texas at Austin's Cockrell School of Engineering has built the first-ever circulator for sound. The team's experiments successfully prove that the fundamental symmetry ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
World's first 3-D acoustic cloaking device hides objects from sound
(Phys.org) —Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic cloak. The ...
Acoustic lens generates tunable 'sound bullets' for ultrasound applications
How the kettle got its whistle
(Phys.org) —Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.
Frogs without ears hear with their mouth
Gardiner's frogs from the Seychelles islands, one of the smallest frogs in the world, do not possess a middle ear with an eardrum yet can croak themselves, and hear other frogs. An international team of scientists ...
Researchers reveal how hearing evolved
Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. These early terrestrial vertebrates were probably also able to hear 300 million years ago, as shown in a new study ...
