Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD), in collaboration with international partners, have developed momentum-resolved Floquet optical selection rules. They show how these symmetry-based rules determine the spectral weight distributions of photon-dressed sidebands in time- and angle-resolved photoemission spectroscopy (TrARPES) experiments across different pump-probe configurations. This fundamental work has now been published in Science Advances.

Last year, spectators along China’s Qiantang River witnessed an unusual sight: waves arranging themselves into a grid-like formation.

This striking pattern, named the “matrix tide,” arose from the river’s famous tidal bores that rush upstream against the flow. In this case, two undular bores — shockwave-like surges that spread outward like ripples on water — traveled in different directions and collided, creating the effect.

Commvault patched four flaws before 11.36.60, including CVE-2025–57790 (8.7 CVSS), preventing remote code execution.

Researchers are taking the laser out of LASIK by remodeling the cornea, rather than cutting it, in initial animal tissue tests.

The attempt was only possible thanks to some pre-gaming with pure oxygen, but still eye-popping.
