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.

Quantum mechanical principle of strong coupling leads to better optical sensors
A team of researchers from the University of Cologne, Hasselt University (Belgium) and the University of St Andrews (Scotland) has succeeded in using the quantum mechanical principle of strong light-matter coupling for an optical technology that overcomes the long-standing problem of angular dependence in optical systems.
The study, “Breaking the angular dispersion limit in thin film optics by ultra-strong light-matter coupling,” published in Nature Communications presents ultra-stable thin-film polariton filters that open new avenues in photonics, sensor technology, optical imaging and display technology.
The study at the University of Cologne was led by Professor Dr. Malte Gather, director of the Humboldt Center for Nano-and Biophotonics at the Department of Chemistry and Biochemistry of the Faculty of Mathematics and Natural Sciences.
How Intense Starbursts Forged the Universe’s Massive Galactic Giants
Researchers have discovered that old elliptical galaxies can form from intense star formation in early galaxy cores.
This finding, derived from data analyzed by the Atacama Large Millimeter/submillimeter Array, shows that these spheroidal galaxies, often considered static and inert, were once dynamic regions of intense star formation during the cosmic noon. This transformative view on galaxy evolution helps clarify the processes behind the formation of the universe’s most massive galaxies.

NASA’s Artificial Star To Unlock Secrets of Exoplanets, Dark Energy, and Supernovae
NASAs new Landolt mission, launching in 2029, will orbit an artificial star around Earth to enhance stellar and planetary measurements.
This will improve the accuracy of stellar brightness calculations by over ten times, aiding in our understanding of planets orbiting these stars and providing insights into dark energy.

China’s Knockoff of US Military Tech: A Spherical Robot That’s a Joke, Revealing Serious Weaknesses
Imagine this: a round, plump robot, like a giant bowling ball, that can roll on land, swim in water, and perform all sorts of high-tech operations. On October 9th, a team of scientists from Zhejiang University unveiled something called the RT-G spherical robot, claiming it’s a \.

Volcanic Eruption in the Philippines Forces Mass Evacuation
The Philippine authorities ordered nearly 90,000 people to evacuate after a volcano on the central island of Negros erupted, spewing a two-mile-high plume of deadly ash, lava and large rocks.
The volcano, Mount Kanlaon, erupted on Monday afternoon, and the authorities warned that it could happen again in the coming days.
“This is very destructive and it can burn everything in its path, including vegetation, buildings and humans,” said Teresito Bacolcol, the head of seismology at the Philippine Institute of Volcanology and Seismology. “This can kill.”
