Inherent chiral Smith–Purcell effect observed through symmetry breaking

A team has experimentally observed the inherent chiral Smith–Purcell effect, a version of Smith–Purcell radiation in which the emission depends on the chirality of the electron beam and of the structure it passes. The effect arises naturally when the symmetry of the system is broken, without the need for external chiral materials or added magnetic fields.

35 years of satellite altimetry compare this Niño with the strongest on record

A 35-year record of satellite altimetry allows scientists to place this year's El Niño alongside its strongest predecessors. The comparison rests on continuous measurement of sea surface height, a direct indicator of heat accumulation in the equatorial Pacific that characterizes the phenomenon.

Satellite altimetry measures sea level to centimetre precision from orbit, recording the thermal anomalies that show up as bulges in the tropical Pacific Ocean. That continuous record, begun more than three decades ago, is now the benchmark for assessing the magnitude of each El Niño episode against the major historical events.

“A 35-year record of satellite altimetry allows scientists to place this year's El Niño alongside its strongest predecessors.”
