Frequency-scanning systems with narrow instantaneous linewidth hold promise for various fields. Here, the authors report the use of time-variant parity-time symmetry to dynamically narrow the instantaneous linewidth of frequency-scanning systems.

Current optical skyrmion generators involve complex bulky systems, hindering further practical applications. We propose an integrated metafiber for high-quality photonic skyrmions, with subwavelength polarization features and topology tunability.

Honda claims its future EVs will even go as far as 776 miles on a full charge after 2040. There is one big issue, though.
Researchers at the University of Cambridge are close to recreating the movements of the world’s first land animals.
ANCHORAGE, Alaska (AP) — An increase in the number of earthquakes under a volcano near Alaska’s largest city this year has geologists paying attention.
Mount Spurr, about 80 miles (129 kilometers) northwest of Anchorage, last erupted in 1992, spewing an ash cloud nearly 12 miles (19 kilometers) into the air, prompting flights to be canceled and people to don masks. Another eruption at the 11,100-foot (3,383-meter) stratovolcano could be severely disruptive to the city, according to the Alaska Volcano Observatory.
The observatory raised its alert status for Mount Spurr in October — from green to yellow — when the increase in seismic activity became pronounced and a ground deformation was spotted in satellite data. Observatory scientist David Fee said Friday there have been about 1,500 small earthquake below the volcano this year, compared to about 100 in a normal year.
Light Field Lab has launched its SolidLight Holographic and Volumetric display technologies that will power some amazing imagery of the future.
These next-generation display technologies will be used by major companies to build a wide variety of holographic images and animations. Connecting a bunch of panels together, the system can modulate 10 billion pixels per square meter.
Last year, Light Field Lab raised $50 million, adding to its war chest of $85 million raised since its inception. And now I can see where that money is going. The San Jose, California-based company gave me a theatrical tour of an animated demo of an alien that it builds in collaboration with the SETI Institute, the organization searching for extraterrestrial intelligence in our galaxy.
