Supersonic skydiver reached 844 mph in record jump (Update)
Supersonic Austrian skydiver Felix Baumgartner was faster than he or anyone else thought during his record-setting jump last October from 24 miles (38 kilometers) up.
Listening to cells: Scientists probe human cells with high-frequency sound
Sound waves are widely used in medical imaging, such as when doctors take an ultrasound of a developing fetus. Now scientists have developed a way to use sound to probe tissue on a much tinier scale. Researchers from the ...
Scientists use Amazon Cloud to view molecular machinery in remarkable detail
In this week's Nature Methods, Salk researchers share a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images.
VISIONS: Seeing the aurora in a new light
On a cold February night in Poker Flat, Alaska, a team of scientists will wait patiently for the exotic red and green glow of an aurora to illuminate the sky. Instead of simply admiring the view, this group ...
Construction begins on Canada's largest radio telescope
Construction is now under way in Penticton, B.C. on Canada's largest radio telescope – and the first research telescope to be built in the country in more than 30 years.
World's largest natural sound archive now online
(Phys.org)—After 12 years of work, Cornell's Macaulay Library archive, the largest collection of wildlife sounds in the world, is now digitized and fully available online.
Tropical cyclone waves detected with infrasound sensor array
The strong winds of a tropical cyclone whip up the sea surface, driving ocean waves a dozen meters (about 40 feet) high. When one such ocean wave runs into another wave that has an equal period but is traveling in the opposite ...
New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.
Banded mongooses structure monosyllabic sounds in a similar way to humans
Animals are more eloquent than previously assumed. Even the monosyllabic call of the banded mongoose is structured and thus comparable with the vowel and consonant system of human speech. Behavioral biologists ...
Songbird sings in 3D
The question 'How do songbirds sing?' is addressed in a study published in BioMed Central's open access journal BMC Biology. High-field magnetic resonance imaging and micro-computed tomography have been u ...
Noise protection: Multifunctional and aesthetical
Noise abatement is growing in importance, thus, the demand for better acoustic building components raises. Scientists are developing new solutions: aesthetically good looking and flexibly applicable microperforated ...
Super-fine sound beam could one day be an invisible scalpel
A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound ...
Perfecting sound quality in-ear
An audio pioneer who has worked with the likes of Stevie Wonder, Bon Jovi and Pink Floyd, Stephen Ambrose is on a quest to perfect sound quality. His most recent innovation is a modification for ear buds, ...
Recreate the concert in the living room
Hear music of concert hall quality at any place in the room from a stereo recording. The device created by EPFL spin-off Illusonic creates an "acoustic space."
