Phys.org / Sea creatures reveal the physics behind animal body shape diversity
Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, jellyfish, and sea anemones ...
Phys.org / How clonal raider ants update their friend-or-foe recognition
For ants, the ability to instantly distinguish nestmates from outsiders who might hijack the colony is crucial. Now, a new study shows that the system that ants use to determine who belongs in the colony is far more flexible ...
Phys.org / Low-cost test dissolves threat of fake drugs
Fake news can be tricky to spot, but spotting fake drugs just got a little easier. Researchers have devised a low-cost way to help distinguish legitimate medications from counterfeit ones.
Phys.org / Cells in the mosquito's gut drive its appetite, research shows
Researchers have known for decades that female mosquitoes—the ones responsible for the itchy and irritating bites that can also transmit disease—lose their desire to bite humans for several days after feeding, as they ...
Phys.org / 'Plastic-eating' fusion enzyme improves polyester textile recycling
In a new study, scientists from the universities of Portsmouth and Manchester report that a specially engineered enzyme can significantly speed up the breakdown of PET—the plastic used in water bottles, food packaging and ...
Phys.org / Pompeii's battle scars linked to an ancient 'machine gun'
The ancient city of Pompeii is one of those archaeological sites that keeps on giving with one discovery after another. While much of what we know about the Roman settlement comes from the eruption of Vesuvius in AD 79, another ...
Phys.org / The discovery of a buried delta on Mars could boost the search for life
There's more evidence that water once flowed on Mars with the discovery of an ancient river delta deep below the surface. NASA's Perseverance rover found it more than 35 meters beneath Jezero Crater using ground-penetrating ...
Phys.org / The Yamna reused sacred spaces in the north Pontic Steppe, study suggests
According to an article published in Antiquity by Dr. Svitlana Ivanova and her colleagues, the Yamna culture's repurposing of older ritual spaces reflects a deliberate appropriation and continuation of sacred spaces. A case ...
Phys.org / DESI maps C-19, an extremely metal-poor Milky Way stellar stream
Using the Mayall 4-meter telescope at Kitt Peak National Observatory, an international team of astronomers has observed C-19—an extremely metal-poor stellar stream in the Milky Way's halo. Results of the observational campaign, ...
Phys.org / 'Miracle': Europe reconnects with lost spacecraft
The European Space Agency announced Thursday it has re-established communication with a spacecraft that is part of its Proba-3 mission, after losing contact with the satellite a month ago.
Phys.org / Earthquake scientists reveal how overplowing weakens soil at experimental farm
Plowing, or tilling, is an age-old agricultural practice that readies the soil for planting by turning over the top layer to expose fresh earth. The method—intended to improve water and nutrient circulation—remains popular ...
Phys.org / No exotic physics needed: A new formation mechanism of skyrmions inside magnets
Skyrmions, in which electron spins inside a magnet are arranged like vortices, are a key structure in next-generation spintronics technology. KAIST researchers have shown that skyrmions can form using only the fundamental ...
