Researchers from the Institute of Deep-sea Science and Engineering (IDSSE) of the Chinese Academy of Sciences, in collaboration with the University of Pisa, Italy, and the National Institute of Water and Atmosphere Research, New Zealand, have now documented the world’s deepest and largest known aggregation of whale fossils and active whale-fall ecosystems. This deep-sea site, referred to as a “whale necropolis” due to its vast size, is located in the Diamantina Zone of the southeastern Indian Ocean and contains evidence of cetacean falls for at least 5.3 million years.

Quantum cascade laser (QCL) frequency combs face bandwidth limitations (~100 cm⁻¹) that challenge carrier-envelope offset frequency locking. This work demonstrates ultra-broadband QCLs using a diagonal multi-state-to-continuum active region design, achieving ~600 cm⁻¹ electroluminescence at 298 K. Devices deliver 2.72 W peak power with 1.2 μm lasing bandwidth and 1.93 μm at 80 K, advancing single-stack mid-infrared semiconductor lasers for spectroscopy and communications.
A newly developed laser Speckle-based Curvature Optical Metrology (SCOM) system is enabling high-precision, two-dimensional curvature mapping of strongly curved and freeform X-ray mirrors—expanding the boundaries of optical fabrication and beamline performance.
Scientists in China have proposed a generalized Doppler effect framework by constructing vector-polarized dual-vortex light fields via spin–orbit coupling. A single reflection generates four independent frequency-shift signals, with mixed signals offering an order-of-magnitude improvement in measurement accuracy and unambiguous motion direction discrimination. This technique unifies linear, rotational, and vector Doppler methods for precision velocimetry and medical imaging.
As India grapples with searing heat and an erratic monsoon, a perspective paper reveals the crisis is worse than thought—and offers a surprising ray of hope.
