As oceans warm, marine cold spells are disappearing

Marine cold spells are cold versions of heat waves: periods of exceptionally cold water, able to hurt or help the ecosystems they hit. As the atmosphere and oceans warm, marine cold spells are becoming less intense and less ...

Photon pairs are more sensitive to rotations than single photons

Quantum states of light have enabled novel optical sensing schemes, e.g., for measuring distance or position, with precisions impossible to achieve with classical light sources such as lasers. The field of quantum metrology ...

Image: Hubble sees cosmic clues in a galactic duo

This spectacular image from the NASA/ESA Hubble Space Telescope captures the spiral galaxy NGC 105, which lies roughly 215 million light-years away in the constellation Pisces. While it looks like NGC 105 is plunging edge-on ...

How to test the limits of quantum mechanics

Researchers from Imperial College London and Lancaster University have suggested a new approach to test the limits of applicability of quantum mechanics.

Social science for algorithmic societies

Machine learning algorithms pervade modern life. They shape decisions about who gets a mortgage, who gets a job, and who gets bail, and have become so enmeshed in our political and economic processes that some scientists ...
