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 ...

Global study on bird song frequency

An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the ...

Pump down the volume: Study finds noise-cancelling formula

Noisy, open-plan offices full of workers hunched over desks while wearing noise canceling headphones could soon be a thing of the past, thanks to new research from The Australian National University (ANU).

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 ...
