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 the mechanical beat ...

Network turns soldiers' helmets into sniper location system

(PhysOrg.com) -- Imagine a platoon of soldiers fighting in a hazardous urban environment who carry personal digital assistants that can display the location of enemy shooters in three dimensions and accurately identify the ...

Numerical model pinpoints source of precursor to seismic signals

Numerical simulations have pinpointed the source of acoustic signals emitted by stressed faults in laboratory earthquake machines. The work further unpacks the physics driving geologic faults, knowledge that could one day ...

Acoustic emissions from organic martensite analogues

Some organic crystals jump around when heated up. This happens because of an extremely fast change in their crystal structure. In the journal Angewandte Chemie, scientists have now demonstrated that the crystals send out ...

Ant antennae provide vital ID information, study finds

University of Melbourne scientists have shone a new light into the complexities of ant communication, with the discovery that ants not only pick up information through their antennae, but also use them to convey social signals.

Fruit flies adjust their courtship song based on distance

Outside of humans, the ability to adjust the intensity of acoustic signals with distance has only been identified in songbirds. Research published Feb. 3, 2016 in Neuron now demonstrates that the male fruit fly also displays ...

Making frequency-hopping radios practical

The way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. In some regions, for instance, the frequencies used by cellphones can be desperately congested, while ...
