The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled of stars in and around our home galaxy. Go to Source Supercontinuum light sources—often called “white lasers” because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers have historically faced a frustrating trade-off: A broad spectrum comes at the expense of high fluctuations, which has effectively limited their use. Go to Source […] Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons. This makes the platform not only a new type of solution-processed laser but also a powerful way to study nonlinear polariton interactions. The paper […] For the first time, scientists have observed a three-dimensional woven structure forming naturally inside a crystal, revealing a previously unknown way in which matter can organize itself. Go to Source A KAIST research team led by professor Mooseok Jang from the Department of Bio and Brain Engineering has developed a single-shot phase imaging technique that reconstructs a phase object—a transparent object such as glass, plastic film or a living cell, which produces almost no visible contrast under an ordinary camera but induces a subtle shift […] Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now achieved a fourfold resolution boost compared to a classical microscope, using a new optical design that […] FBI officials stated the agency is using UAS countermeasures to bring drones down after firefighting aircrafts were grounded Go to Source A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 light-years, long—feeding the young triple-star system GW Orionis. These new observations provide the clearest evidence yet for how such “streamers” can tilt and twist the disks where planets are born. The findings are […] Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes that led to the formation of two striking features surrounding the black holes at the centers of most galaxies: nuclear star clusters and nuclear stellar disks. Only […] Narrow jets of luminous matter may be emitted toward Earth from the nuclei of active galaxies billions of light-years away. The galaxy then appears as a point source and is called a blazar. A Polish-German team of scientists has, for the first time, analyzed the activity of one such blazar over an extended period and, […] Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions in which these phases are reached could help researchers learn more about how planets evolve. Go to Source […] A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of “leaky” galaxies was responsible for cosmic reionization. The paper outlining this work was posted to the arXiv preprint server on July 24. Go to Source The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth. Go to Source At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball with spin-parity quantum numbers of 0⁻⁺.
