(PhysOrg.com) -- A study of the Central American red-eyed tree frog has found that the males shake the branches they’re perched on to produce strong vibrations to mark out their territory for mating.
EPFL scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor ...
