BOSS quasars track the expanding universe—most precise measurement yet
The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS-III), pioneered the use of quasars to map density variations in intergalactic gas at high ...
Physicists split and collide ultracold atom clouds (w/ Video)
Physicists at New Zealand's University of Otago have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds ...
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 ...
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 ...
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Surfing on acoustic waves (w/ Video)
(Phys.org) —ETH researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control ...
