Pattern in whale songs predicts migration

Through the use of two advanced audio recording technologies, a collaboration of Monterey Bay researchers has found that blue whales switch from nighttime to daytime singing when they are starting to migrate.

Record-breaking, floating laser resonator

Physical Review X recently reported on a new optical resonator from the Technion—Israel Institute of Technology that is unprecedented in resonance enhancement. Developed by graduate student Jacob Kher-Alden under the supervision ...

Carbon-carbon covalent bonds far more flexible than presumed

A Hokkaido University research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...

Detection of gravitational wave 'lensing' could be some way off

Gravitational wave scientists looking for evidence of "lensing," in which the faintest gravitational wave signals become amplified, are unlikely to make these detections in the near future according to new analysis by scientists ...
