Phys.org / Webb telescope sheds light on ancient 'monster stars' that may reveal the birth of black holes
Using data from NASA's James Webb Space Telescope, astronomers from the Center for Astrophysics | Harvard & Smithsonian (CfA) have revealed the universe's most mysterious distant objects, known as little red dots, may actually ...
Phys.org / Researchers build plasma accelerator that boosts electron energy and brightness at the same time
Researchers from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles (UCLA), have designed innovative technology that can generate both high-energy and high-brightness ...
Phys.org / New census of sun's neighbors reveals best potential real estate for life
A new study led by a Georgia State University astronomy graduate student is a major step forward in the search for stars that could host Earth-like planets that may prove to be good havens for life to develop. Sebastián ...
Phys.org / Dentin inside wolffish teeth is a rare material: When compressed along its length—it also shrinks in width
The Atlantic wolffish is known for its powerful bite, capable of crushing hard-shelled prey with ease. Now, researchers have discovered that the fish's teeth don't just withstand these extreme forces, they respond in a way ...
Phys.org / The (metabolic) 'cost of life': New method quantifies hidden energy costs of maintaining metabolic pathways
There are "costs of life" that mechanical physics cannot calculate. A clear example is the energy required to keep specific biochemical processes active—such as those that make up photosynthesis, although the examples are ...
Phys.org / Electrons that lag behind nuclei in 2D materials could pave way for novel electronics
One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists to understand for the first time how and why certain materials conduct electric current and how ...
Phys.org / Catalyst behavior that could cut emissions and stabilize supply of everyday materials revealed
A Rice University-led team has unveiled how tiny molecular structures on industrial catalysts behave during the manufacture of vinyl acetate monomer (VAM), a core ingredient in adhesives, paints, coatings, packaging, textiles ...
Phys.org / Webb reveals a sample of galaxies with unusual features, nicknamed 'Platypus'
After combing through NASA's James Webb Space Telescope's archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have ...
Phys.org / Direct 3D printing of nanolasers can boost optical computing and quantum security
In future high-tech industries, such as high-speed optical computing for massive AI, quantum cryptographic communication, and ultra-high-resolution augmented reality (AR) displays, nanolasers—which process information using ...
Phys.org / Webb finds early-universe analog's unexpected talent for making dust
Using NASA's James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one of the most chemically primitive galaxies near the Milky Way.
Phys.org / Programmable microparticles morph and self-propel under electrical fields
Researchers at CU Boulder have created tiny, microorganism-inspired particles that can change their shape and self-propel, much like living things, in response to electrical fields.
Phys.org / Nanoparticles with AI-crafted sensors open paths to at-home cancer screening
Detecting cancer in the earliest stages could dramatically reduce cancer deaths because cancers are usually easier to treat when caught early. To help achieve that goal, MIT and Microsoft researchers are using artificial ...
