Phys.org / Milky Way-like simulation reveals how central galactic structures grow together
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 ...
Phys.org / Researchers demonstrate first fully solution-processed solid-state polariton laser
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 ...
Phys.org / Charting the galaxy: Milky Way Mapper survey releases latest all-sky spectra
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 ...
Phys.org / Observing key material properties atom by atom for the first time
Many material properties depend on how electrons are arranged inside a material. Their distribution determines, for example, whether a material conducts electricity or displays magnetic behavior. Understanding how electrons ...
Phys.org / Mitochondria act as sensors for essential iron molecule, study reveals
Heme, a bioactive form of iron, has numerous essential functions in the cell. As a key component of hemoglobin, it enables oxygen transport in the blood. In addition, it performs important functions in other proteins in processes ...
Phys.org / Powerhouses for fake meat: Muscle protein can now be grown in chloroplasts of lettuce and tobacco plants
Livestock farming requires valuable land to grow fodder, uses vast amounts of freshwater and contributes to global warming through methane and nitrous oxide emissions. And, for many consumers it is important to prevent animal ...
Phys.org / Decoding the North American bison's genome to better inform conservation efforts
A new study by ancient DNA researchers at the University of California, Santa Cruz, used paleogenomics to create a genetic roadmap to help guide the restoration of another iconic species once on the brink of extinction: the ...
Phys.org / AI for homework—parents more willing to pay subscriptions for their children as peer pressure rises
Many parents have mixed feelings about the unrestricted use of artificial intelligence (AI) for schoolwork. They are concerned about the potential impact on their child's ability to learn but also don't want them to be left ...
Phys.org / First complete songbird genome exposes missing genes and chromosome architecture
The zebra finch is one of the best-studied songbirds and a model for understanding the biology and neuroscience of vocal learning. Now, researchers have produced the first complete genome assembly of the species, revealing ...
Phys.org / Never-before-seen woven structure that forms naturally inside a crystal discovered
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.
Phys.org / An elegant modification doubles the range of low-noise 'white lasers' in a single fiber
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 ...
Phys.org / Trillion-mile gas streamer may explain tilt of triple-star system's outer planet-forming ring
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 ...
