Physicists use mechanical micro-drum used as quantum memory
JILA researchers demonstrated thatinformation encoded as a specific point in atraveling microwave signal—the vertical and horizontal positions of a wave pattern at a certain ime—can be transferred to ...
Using sound waves for bomb detection
(Phys.org) —A remote acoustic detection system designed to identify homemade bombs can determine the difference between those that contain low-yield and high-yield explosives.
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.
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.
Researchers replicate supershear earthquakes in the lab
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.
Why does Venus' atmosphere rotate sixty times faster than its surface?
Venus is a slowly rotating planet since it takes about two hundred and forty three terrestrial days to complete a round about itself. Its atmosphere is expected to rotate with the same rhythm as well, but ...
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.
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 ...
