This week, researchers reported on a juvenile great white shark caught by fishermen in Spanish Mediterranean waters. China's clean air initiatives have resulted in major public health gains, but may have one unintended consequence. ...
Phys.org / What we can learn from lovebirds, the rare birds that mate for life
Minutes after getting to a park in the middle of Phoenix, you can see flashes of green in the sky and hear chatter because love is in the air—or at least, the lovebirds are.
Phys.org / Time crystals could become accurate and efficient timekeepers
Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by Ludmila Viotti at the Abdus ...
Phys.org / Arctic peatlands are expanding as temperatures continue to rise, new research confirms
The Arctic is warming faster than the rest of the planet, with average temperatures increasing by about 4°C in the last four decades. A new study, led by the University of Exeter, shows peatlands have expanded since 1950, ...

An international team of astronomers has conducted photometric and spectroscopic observations of a recently discovered supernova designated SN 2024abfl. Results of the observational campaign, presented February 4 on the preprint ...
Phys.org / Most precise map yet of agricultural emissions charts a path to reduce hotspots
To lower agricultural emissions, policymakers and communities first need to pinpoint the sources—not just by country but crop by crop, field by field. In a study published in Nature Climate Change, researchers have synthesized ...
Phys.org / How did humans develop sharp vision? Lab-grown retinas show likely answer
Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found. The findings could upend ...
Phys.org / Syntax discovered in the warbling duets of wild parrots
With a few minutes of searching, anyone can find videos online of chatty birds: macaws talk to their keepers, cockatoos sing to the camera, corvids mimic the jarring sounds of construction sites. Research has shown that some ...
Phys.org / The IceCube experiment is ready to uncover more secrets of the universe
The name "IceCube" not only serves as the title of the experiment, but also describes its appearance. Embedded in the transparent ice of the South Pole, a three-dimensional grid of more than 5,000 extremely sensitive light ...
