Phys.org / Pill bugs don't just use the minerals they eat—they rebuild them inside their bodies
Placing small stones in a bug cage is beneficial when raising pill bugs, a type of woodlouse. Researchers at the University of Tsukuba have discovered that pill bugs do not directly incorporate ingested calcium carbonate ...
Phys.org / JWST spots methane on a giant exoplanet, but its star may be distorting the signal
Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have observed a giant exoplanet known as HATS-75 b. Results of the new observations, published April 8 on the arXiv ...
Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
Phys.org / Self-propulsion or slow diffusion: How bacteria, cells, and colloids respond to stimuli
What physical processes govern the movement of microscopic structures capable of interacting with their environment? The answer lies in two mechanisms: self-propulsion, to escape unfavorable locations; and slow diffusion, ...
Phys.org / Ancient seabird guano reveals how climate change may shape future populations
By analyzing peat cores, researchers have shown how populations of nesting seabirds have fluctuated on a sub-Antarctic island over 8,000 years. They found that bird numbers rose and fell alongside shifts in climate, offering ...
Phys.org / Any color you like: Scientists create 'any wavelength' lasers in tiny circuits for light
Computer chips that cram billions of electronic devices into a few square inches have powered the digital economy and transformed the world. Scientists may be on the cusp of launching a similar technological revolution—this ...
Phys.org / Can naked mole rats peacefully hand over power?
Naked mole rats keep kingdoms underground. One queen bears all the children, while others maintain complex subterranean tunnels, forage for food, take care of newborns, and perform other necessary upkeep. This society hinges ...
Phys.org / Electrons crack open organic solar cells, exposing their hidden 3D molecular architecture in a single microscope
How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access even with advanced techniques. So far, researchers have relied mainly on X-ray methods to understand ...
Phys.org / Emerging in Alaska, dominant H5N1 strain spread continent-wide through migratory birds
An international group of scientists mapped the spread of the current dominant strain of highly pathogenic avian influenza virus through North American bird populations in 2024. Led by scientists from St. Jude Children's ...
Phys.org / 4,000-year-old clay tablets inscribed with magical spells… and beer tabs
For over 100 years, the National Museum has housed a large collection of inscribed tablets from the earliest civilizations of the Middle East—many over 4,000 years old and written in languages that are now extinct. The tablets ...
Phys.org / How farming changed us: Ancient DNA reveals natural selection sped up in recent human evolution
A massive study of ancient DNA from nearly 16,000 people across more than 10,000 years in West Eurasia reveals that natural selection has shaped modern human genomes far more than previously thought.
Phys.org / Earth's microbes may hide a near-universal plastic-eating arsenal, with 600,000 proteins poised to attack waste
Researchers have identified more than 600,000 microbial proteins capable of breaking down natural and synthetic plastics, revealing a far broader biodegradation potential across microbes than previously known.
