Researchers Develop Flow Sensors Based on Blind Fish Hair Structures
(PhysOrg.com) -- A blind fish that has evolved a unique technique for sensing motion may inspire a new generation of sensors that perform better than current active sonar.
Researchers replicate supershear earthquakes in the lab
Whale of a difference: Researchers double depth at which technology can identify whale prey
Shipboard echosounders can help scientists find and identify life in the ocean, from schools of fish to diving seabirds and even flurries of tiny krill.
DEIMOS joins MARS and its satellite of instruments on seafloor
The planet Mars has a moon named Deimos, so it seems only appropriate that the ocean observatory MARS in Monterey Bay have its own DEIMOS. This DEIMOS, however, is an underwater acoustic package designed to ...
Flying Telescope Passes Key Test
Most astronomers wouldn't dream of opening their observatory's doors in 100 mph winds. Yet NASA's new SOFIA telescope recently flew in an airplane at 250 mph with doors wide open.
Acoustic waves warn of tsunami
An early warning system against tsunamis has been developed and tailored for the need of the Mediterranean, but preparedness on the ground is paramount to ensuring peoples' safety.
Decoding the long calls of the orangutan
Research into the long calls of male Orangutans in Borneo has given scientists new insight into how these solitary apes communicate through dense jungle. An acoustic analysis of the calls, published today ...
Sensor predicts glass breakage
(PhysOrg.com) -- Modern glass façades inform the architecture of major cities throughout the world. In recent years, however, there have been cases of broken glass, with collapsing facades endangering passers-by. ...
New system helps explain salmon migration
A new acoustic telemetry system tracks the migration of juvenile salmon using one-tenth as many fish as comparable methods, suggests a paper published in the January edition of the American Fisheries Society ...
When a whistle beats a tweet
Biologists have discovered that a species of Australian pigeon has a secret way of alerting fellow birds to predators -- a "whistle" emitted by flapping wings when the bird takes off in alarm.
'Nano-earthquakes' hold key to smarter electronics
The performance of mobile phone cameras and solar cells could be boosted by "nano-earthquakes", researchers have found.
Researcher construct invisibility cloak for thermal flow
By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation ...
Scientists develop new method of estimating fish movements underwater
How do you track a fish? There's no "Google Maps" for finding fish. The radio signals that are the backbone of traditional GPS cannot pass through seawater. But sound travels remarkably well, so scientists ...
Chickadees Tweet About Themselves
A short tweet from a chickadee can tell other birds their sex, species and geographic location, according to new research.
