Phys.org / Cutting a photon in two creates an infinite swarm of particles
By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway ...
Phys.org / Rare meteorite provides evidence of giant early planet
Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal ...
Phys.org / Plate tectonics shaped the Cradle of Civilization by merging two ancient rivers, study suggests
The Euphrates River is the longest river in Western Asia and runs through the eastern side of the Fertile Crescent. Flowing over 1,700 miles from Turkey through Syria and Iraq, the river played a crucial role in sustaining ...
Phys.org / Single cell transforms into cannibalistic 'supergiant,' swallowing its clones whole
Researchers at Rensselaer Polytechnic Institute (RPI) have discovered a microscopic organism that can transform into a cannibalistic "supergiant" that drastically changes size, shape, and behavior, and abandons filter-feeding ...
Phys.org / Terahertz imaging maps spatial chirality in materials with 100-micrometer resolution
In nature, there exist structures that are mirror images of each other but cannot be perfectly superimposed. These are known as chiral objects, derived from the Greek word for "hand," since left and right hands share the ...
Phys.org / Ötzi the Iceman and his microbiome—a 5,300-year-old relationship
Researchers at Eurac Research have obtained a detailed picture of the microbial community associated with Ötzi, Europe's oldest known natural human mummy. The study provides insights into a complex microbiome, ranging from ...
Phys.org / Kamo'oalewa asteroid's lunar origin challenged ahead of Tianwen-2 arrival
China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had ...
Phys.org / Leafy camouflage reshapes katydid love songs, making males more attractive to females
New research from the University of St Andrews has discovered that insects who conceal themselves as leaves also use their leafy camouflage to amplify mating calls, making themselves more attractive to the opposite sex. The ...
Phys.org / Atomic reshuffle leads to record-breaking catalysts for hydrogen production
Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created ...
Phys.org / City birds dazzle females with 'borrowed' human items
Bowerbirds in an Australian city use a range of human items—from glass and plastic to banknotes and even a pair of handcuffs—to impress females, shows new research in Royal Society Open Science. Male bowerbirds create an ...
Phys.org / How a Richard Feynman formula could explain your dining habits in a new city
One of the dilemmas facing anyone in a new and unfamiliar city is where to dine out. You might consult guides, speak to locals, check reviews, and ultimately, try your luck. But if you're there for a while, at some point ...
Phys.org / Climate-based tool predicts coral bleaching months in advance, offering critical lead time for reef protection
Researchers at the Woods Hole Oceanographic Institution (WHOI) have developed a new method to predict coral bleaching five to six months before it occurs, giving reef managers valuable time to protect vulnerable ecosystems. ...
