Acoustic tweezers capture tiny creatures with ultrasound (w/ Video)
A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms, using sound waves, according to a team of bioengineers and biochemists from Penn State.
Researchers create the most detailed map ever of an underwater lava flow
(Phys.org) -- Axial seamount, 480 kilometers (300 miles) off the coast of northern Oregon, is one of the best-studied underwater volcanoes in the world. For 30 years, researchers have explored this volcano ...
Manipulating tiny animals with sound waves: Researchers develop a new kind of 'tweezers'
By using sound waves to push and pull matter like science fiction tractor beams, scientists have developed "acoustic tweezers" that can manipulate blood cells and microscopic worms on a platform the size of ...
The use of acoustic inversion to estimate the bubble size distribution in pipelines
New research from the University of Southampton has devised a new method to more accurately measure gas bubbles in pipelines.
Spain the dunces in international science test
Spaniards came bottom of the class in an 11-nation science test and nearly half of them could not name a single important scientist in history, a survey showed Tuesday.
Official: Dolphin deaths in Peru still a mystery
(AP) -- Peruvian authorities are still trying to unravel the mystery of why hundreds of dolphins ended up dead on beaches in the country over the past 2 1/2 months.
Can sound science guide dispersant use during subsea oil spills?
Two years ago this week, oil began streaming from the seafloor into the Gulf of Mexico following the explosion of the Deepwater Horizon platform. All told, the disaster cost 11 lives, released 4.9 million ...
Study amplifies understanding of hearing in baleen whales
For decades, scientists have known that dolphins and other toothed whales have specialized fats associated with their jaws, which efficiently convey sound waves from the ocean to their ears. But until now, the hearing systems ...
When dark energy turned on (Update)
(PhysOrg.com) -- Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction ...
Sound effects inspired Stonehenge: US scientist
Ancient legends of thunder gods can be explained today with the modern science of sound waves, said a US scientist on Thursday who believes an auditory illusion inspired the creation of Stonehenge.
Quantum microphone captures extremely weak sound
(PhysOrg.com) -- Scientists from Chalmers have demonstrated a new kind of detector for sound at the level of quietness of quantum mechanics. The result offers prospects of a new class of quantum hybrid circuits ...
Researchers transfer the concept of an optical invisibility cloak to sound waves
Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object ...
Seeing sound: Team develops noninvasive method to visualise sound propagation
High-performance loudspeaker manufacturers have been able to improve sound quality dramatically over the years, but still face the issue of dead spots.
Physicists localize 3-D matter waves for first time (w/ video)
University of Illinois physicists have experimentally demonstrated for the first time how three-dimensional conduction is affected by the defects that plague materials. Understanding these effects is important ...
