At night, as cold settles in, lake ice creaks and groans. It's been excessively cold, and I camped exposed on the snow-swept surface. Other than the lack of vegetation and the sounds at night, you'd never know you were on a lake. It feels like an empty plain. In some places, you see pressure ridges where ice has pushed into itself, sticking up like clear blue stegosaurus plates.—Craig Childs
When an organism is exposed to life-threatening conditions, it sounds the alarm and a cellular emergency program, the heat shock response, is initiated. However, the name "heat shock response" is misleading. In the beginning of the 1960s, this form of stress response was first observed. Scientists exposed fruit flies to high temperatures and discovered a complex emergency program designated to save single cells and thus the organism itself. Today researchers know that this program is also triggered by other dangers such as radiation or toxic substances. The terminology, however, is still in use.
Congressman Dana Rohrabacher (R-CA) questions a panel of space and aerospace professionals about the feasibility of the Mars mission at a hearing on Feb. 27th, 2014. Also, why the mission called 'Inspiration Mars' is now looking for public funding.
Mute the song playing on your smartphone in your pocket by flicking your index finger in the air, or pause your "This American Life" podcast with a small wave of the hand. This kind of gesture control for electronics could soon become an alternative to touchscreens and sensing technologies that consume a lot of power and only work when users can see their smartphones and tablets.
Researcher and musician Charles Limb created an fMRI-safe keyboard to study the effects of jazz on the brain.
A Finnish-Brazilian project is constructing a system that could estimate the dynamics of animal populations by using sound recordings, statistics and scientific computing. The canopy in a Brazilian rainforest is bustling with life, but nothing is visible from the ground level. The digital recorders attached to the trees, however, are picking up the noises of birds.
(Karolinska Institutet) Researchers at Karolinska Institutet in Sweden have identified a biological circadian clock in the hearing organ, the cochlea. This circadian clock controls how well hearing damage may heal and opens up a new way of treating people with hearing disabilities.
Two spotted seals orphaned as pups in the Arctic are now thriving at UC Santa Cruz's Long Marine Laboratory, giving scientists a rare opportunity to learn about how these seals perceive their environment. In a comprehensive study of the hearing abilities of spotted seals, UCSC researchers found that the seals have remarkably sensitive hearing in both air and water.
(AP)—I typically have headphones on when I'm home in New York, whether it's during a jog or a commute. I often crank the volume up, at the risk of hearing loss, so that I could hear my favorite podcasts over loud subways and honking cars.
A new project that will use large music collections – so called Big Data – to support music research has been launched by Queen Mary University of London, City University London, University College London and the British Library.
(University of Iowa) According to a new study from researchers at the University of Iowa, our memory for sounds is significantly worse than our memory for visual or tactile things. Results are published in the open-access journal PLOS ONE.
A new study of territorial songs used by chipping sparrows to defend their turf reveals that males sometimes will form a "dear enemy" alliance with a weaker neighbor to prevent a stronger rival from moving in. For the first time findings demonstrate the birds' use of a stereotyped, specialized signal, in this case chipping sparrow trills, to establish brief periods of cooperation among neighbor birds who are otherwise rivals.
A new study of territorial songs used by chipping sparrows to defend their turf reveals that males sometimes will form a "dear enemy" alliance with a weaker neighbor to prevent a stronger rival from moving in. University of Massachusetts Amherst graduate student Sarah Goodwin and her advisor, behavioral ecologist Professor Jeffrey Podos, report their findings in the current issue of Biology Letters.
HTC announced at Mobile World Congress on Monday its new Power To Give project, which aims to donate processor power to scientific research. Planning on bringing together the power of millions of smartphones, the Android for altruism initiative is in the spirit of volunteer distributed computing, set to harness the collective processing power of Android smartphones. The distributed computing project involves a new Power To Give app, expected to land on Google Play shortly. How will this help? HTC's promotional video, against a background music of gentle piano ripples, notes that research scientists all over the world are searching for answers to some of our biggest questions, such as designing new proteins to treat cancer or breaking down toxic compounds in the environment. With the HTC Power To Give initiative, the video tells viewers "you can help."
(AP)—Sony is borrowing innovations from its audio and camcorder businesses and incorporating its new Xperia Z2 smartphone with noise-cancelling technology and ultra-high-definition video recording.
While investigating why and how music evolved in humans, researchers are finding that some animals can keep a beat.
A hearing aid that wirelessly streams audio from an MP3 player? A pair of Google Glass with visual recognition? A bracelet that lets friends send each other "smiles"? These are just a few of the devices forging the future of wearable tech.
The canine brain reacts to voices in the same way that the human brain does - especially when they hear emotionally charged sounds, a study suggests.
Advances in cheap, tough automated recorders and powerful sound-analysis software are inspiring scientists to launch increasingly ambitious efforts that use sound to document and analyze ecosystems. A growing community of self-described soundscape ecologists are capturing thousands of hours of sound—from birdsong and insect choruses to rushing water, thunderclaps, and even the drone of cars and airplanes. Converting complex soundscapes into relatively simple numerical indices of biodiversity is proving difficult, and researchers are struggling to turn huge collections of digital recordings into something they can use. But if they're successful, they'll have a powerful and noninvasive way to describe ecosystems and measure how they're changing.

Human and dog brains process sounds in similar ways, and this may allow the two species to understand each other's emotions, new research shows.
