Phys.org / Antibiotics could trigger immune response through gut microbiome metabolites
The microbes inside our bodies not only help break down food but also impact our health. Yet their precise influence is not always understood, especially in the presence of prescription drugs.
Phys.org / Nursery web spider uses legs to 'sniff out' its partners
Male nursery web spiders (Pisaura mirabilis) use the sense of smell in their legs to find mates. Researchers at the University of Greifswald used an electron microscope to discover "olfactory hairs" on the legs of adult males. ...
Phys.org / Chemists synthesize a fungal compound that holds promise for treating brain cancer
For the first time, MIT chemists have synthesized a fungal compound known as verticillin A, which was discovered more than 50 years ago and has shown potential as an anticancer agent.
Phys.org / Water-resistant and recyclable redox-active MOFs enable stable energy storage in acidic solutions
Redox-active metal-organic frameworks (RAMOFs) are highly porous materials made of metals and organic molecules linked together by coordination bonds, and they contain redox-active sites that can store electrons (protons). ...
Phys.org / A new tunable cell-sorting device with potential biomedical applications
Poly(N-isopropylacrylamide) (PNIPAM) hydrogel undergoes significant but precise changes in size between 20°C and 40°C, making it an excellent candidate for use in variable-size deterministic lateral displacement (DLD) array ...
Phys.org / Fish freshness easily monitored with a new sensor
To see if a fish is fresh, people recommend looking at its eyes and gills or giving it a sniff. But a more accurate check for food quality and safety is to look for compounds that form when decomposition starts.
Phys.org / Debris disk gallery shows tell-tale signs of asteroids and comets in distant solar systems
Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.
Phys.org / Epigenetics linked to high-altitude adaptation in Andes
DNA sequencing technology makes it possible to explore the genome to learn how humans adapted to live in a wide range of environments. Research has shown, for instance, that Tibetans living at high altitude in the Himalayas ...
Phys.org / Tailored single atom platforms hold promise for next-generation catalysis
Catalysts play a vital role in modern society, supporting processes from metallurgy to pharmaceutical production. To reduce environmental impact and maximize efficiency, science has pushed the boundaries between homogeneous ...
Phys.org / Terrestrial biodiversity grows with tree cover in agricultural landscapes
Farmers plant or preserve riparian buffers for various reasons, such as improving water quality, controlling erosion, or maintaining hunting habitat. Now, a new study from the University of Illinois Urbana-Champaign underscores ...
Phys.org / Cats adjust their communication strategy by meowing more when greeting men
As many cat owners will testify, their pets are often mysterious creatures, independent, cunning and sometimes aloof. And now it appears that when it comes to communication, they might be playing favorites. A new study published ...
Phys.org / Alaknanda: JWST discovers massive grand-design spiral galaxy from the universe's infancy
A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies could not yet exist. Two astronomers from India have identified a remarkably mature galaxy just ...
