Medical Xpress / Why it's so easy to choke on fish bones—and the other dangers they pose
Strictly Come Dancing judge Shirley Ballas recently revealed that she'd "thought that was it" after a fish bone became lodged in her throat. Ballas's terrifying ordeal lasted for 20 minutes, with the judge struggling to breathe ...
Phys.org / First 'Bible map' published 500 years ago still influences how we think about borders, study suggests
The first Bible to feature a map of the Holy Land was published 500 years ago in 1525. The map was initially printed the wrong way round—showing the Mediterranean to the East—but its inclusion set a precedent which continues ...
Tech Xplore / The world's most efficient solar cell: Chinese researchers explain how they designed and built it
Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was verified by Germany's ...
Phys.org / Astronomers investigate nearby pulsar with radio telescopes
Using the Large Phased Array (LPA) and the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from Russia and China have observed a nearby pulsar designated PSR J1951+2837. The new observations, presented ...
Phys.org / Shop-bought cable helps power two quantum networks
For decades, physicists have dreamed of a quantum internet: a planetary web of ultrasecure communications and super-powered computation built not from electrical signals, but from the ghostly connections between particles ...
Phys.org / Dark matter-dark energy interaction shapes cosmic halo spin and alignment, simulations show
A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction between dark matter and dark ...
Phys.org / How phototherapy could reverse antibiotic resistance
Lars Stevens-Cullinane works in a dark room. But he's not processing negatives and printing photographs on light-sensitive paper; he's testing whether brief flashes of light can make drug-resistant bacteria sensitive to antibiotics.
Phys.org / Flightless ancestor shows brain evolution in pterosaurs and birds took different paths
Flight is a rare skill in the animal world. Among vertebrates, it evolved only three times: in bats, birds, and the long-extinct pterosaurs. Pterosaurs were the pioneers, taking to the skies more than 220 million years ago, ...
Tech Xplore / Electric vehicle prowess helps China's flying car sector take off
A worker in white gloves inspects the propellers of a boxy two-seater aircraft fresh off the assembly line at a Chinese factory trialing the mass production of flying cars.
Phys.org / Studies show how the giant statues on Rapa Nui were made and moved—and what caused the island's deforestation
Rapa Nui, also known as Easter Island, is often portrayed in popular culture as an enigma. The rationale is clear: The tiny, remote island in the Pacific features nearly 1,000 enormous statues—the moai. The magnitude and ...
Phys.org / Finding information in the randomness of living matter
When describing collective properties of macroscopic physical systems, microscopic fluctuations are typically averaged out, leaving a description of the typical behavior of the systems. While this simplification has its advantages, ...
