Phys.org / Molecular 'reshuffle' cracks an 80-year-old conundrum in controlling chirality
Researchers at the University of St Andrews have uncovered a long‑elusive molecular "reshuffle," a breakthrough that tackles one of chemistry's most persistent challenges and could transform the way medicines are manufactured.
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 / 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 / Twitter data reveals partisan divide in understanding why pollen season's getting worse
Two things are clear from a University of Michigan analysis of nearly 200,000 Twitter posts between 2012 and 2022. One, people are really good at identifying peak pollen season: The largest volume of tweets about pollen often ...
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 / Cracking sleep's evolutionary code: Neuron protection traced back to jellyfish and sea anemones
A new study from Bar-Ilan University shows that one of sleep's core functions originated hundreds of millions of years ago in jellyfish and sea anemones, among the earliest creatures with nervous systems. By tracing this ...
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 / 'Platypus' objects in the early universe look like stars but behave like galaxies
Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA's James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou's College of Arts and Science ...
Phys.org / Mass spec innovation uses 'bin' sorting to detect overlooked molecules
Weight says a lot. In the kitchen, it could mean cooking with too little or too much of an ingredient. For scientists, a molecule's weight can help determine its makeup. This, in turn, can shed light on whether a potential ...
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 / Shelled amoeba crawls like an octopus, shifting tactics on the go
An international team of researchers led by Hokkaido University has characterized the unique mechanics that enable Arcella, a shelled, single-celled amoeba, to move skillfully across different surfaces.
Phys.org / Marine regression emerges as key driver of Late Paleozoic Ice Age in high-resolution model
Earth system box models are essential tools for reconstructing long-term climatic and environmental evolution and uncovering Earth system mechanisms. To overcome the spatiotemporal resolution limitations of current deep-time ...
