NASA Satellite Reveals Dispersive, Pacific-Wide Tsunami Pattern

NASA’s SWOT satellite captured unprecedented high‑resolution, wide‑swath observations of a Pacific-wide tsunami from the Kuril‑Kamchatka earthquake, showing dispersive wave behavior that challenges the traditional non‑dispersive view; by combining SWOT with DART buoy data and inversion analyses, researchers refined the earthquake rupture to about 400 km and highlighted how integrating multiple data sources could improve future tsunami forecasting and warnings.

Revolutionary Optical Device Enabled by Conjoined 'Racetracks'

Researchers at Caltech and UC Santa Barbara have developed a new microcomb device that overcomes the optical limitations of ultra-low-loss silicon nitride (ULL nitride) by generating pulses in pairs. By creating multiple conjoined racetracks, the paired laser pulses bunch up, counteracting the dispersion and allowing the microcombs to work properly. This breakthrough could lead to the integration of microcombs into handheld devices and the creation of large photonic circuit arrays for soliton pulses. The manufacturing scalability of the complementary metal–oxide–semiconductor (CMOS) process makes it easier and more economical to produce these short-pulse microcombs.

Using Fast Radio Bursts to Detect Gas in the Milky Way.

University of Toronto researcher Amanda Cook has used fast radio bursts (FRBs) to weigh the atmosphere of the Milky Way galaxy. FRBs generate brief flashes of radio waves and are considered one of the biggest mysteries in astronomy. Cook used the dispersion method to measure how much gas is present in the Milky Way's halo and discovered that it contains much less gas than previous models had predicted. FRB signals could be used to study the structure of everything that the FRB signal passes through on its long journey, including the material between galaxies, the halos of other galaxies, and the gas inside of galaxies.
