Celestial eruptions known as giant magnetar flares have been seen in our cosmic backyard, but were so bright they blinded observational instruments. The discovery of a more distant flare finally reveals details of these emissions.

A link has been found between repetitive stretches of DNA called tandem repeats and autism spectrum disorder. The discovery might inform approaches to studying tandem repeats in a wide range of other human disorders.

In some materials, the absorption of a single photon can trigger a chain reaction that produces a large burst of light. The discovery of these photon avalanches in nanostructures opens the way to imaging and sensing applications.

Observations of a giant flare associated with the starburst galaxy NGC 253 suggest that the flare is probably associated with relativistic plasma in the magnetic field of a magnetar.

The γ-ray burst GRB 200415A is probably a giant flare emitted from a magnetar in the nearby starburst galaxy NGC 253.
