Science X / Across Bronze Age Sweden, carved footprints point to a ritual for turning social ties into stone
Etched into the ancient rocky outcrops of southern Scandinavia and large boulders left behind by retreating glaciers are footprints, also called podomorphic petroglyphs. Some are barefoot with every toe visible, while others ...
Phys.org / Integrated solar reactor paves way to make 'clean' chemicals, plastics and food using solar energy
A new study led by Dr. Lin Su of Queen Mary University of London, published today in the Journal of the American Chemical Society, describes a new integrated solar reactor in which engineered Escherichia coli (E. coli) are ...
Phys.org / Intrepid tails—fluke photos confirm humpback whales mount 14,000 km open ocean crossing to breeding grounds
An international team of scientists have documented, for the first time, humpback whales traveling between breeding grounds in eastern Australia and Brazil, crossing more than 14,000 kilometers of open ocean. The findings ...
Phys.org / Twisted WSe₂ reveals elusive charge-neutral quantum modes
Quantum materials, materials with properties that are influenced by the laws of quantum mechanics, have attracted considerable attention over the past few decades. Their unique properties make these materials advantageous ...
Phys.org / Beyond 0 and 1: Ferrotoroidic material can store four magnetic states
Today's computers store information using only two values: 0 and 1. But as electronic devices become smaller and reach their limits, scientists are searching for new ways to pack more information into the same space. One ...
Phys.org / New RNA tool maps structure and motifs across organisms and viruses
Researchers at the University of Würzburg have unveiled a new tool for analyzing RNA molecules. It visualizes their structures as interactive maps and could help to improve our understanding of diseases.
Phys.org / Intensifying droughts may be pushing tropical forests toward a dangerous threshold
Tropical forests, often described as the lungs of the planet, may be edging closer to a dangerous threshold as droughts become more frequent and widespread across the world's humid tropics. New research suggests these ecosystems ...
Phys.org / Young Fraser River Chinook salmon swimming in 'chemical soup,' study finds
Juvenile Chinook salmon in the Lower Fraser River estuary are feeding and growing in a slurry of contaminants from pharmaceuticals, personal care products to industrial chemicals, according to a new Simon Fraser University ...
Medical Xpress / Rollback of PFAS drinking water standards raises safety fears
The U.S. Environmental Protection Agency (EPA) said Monday it wants to roll back some regulations on "forever chemicals" in drinking water put into place in 2024.
Phys.org / Visualizing sound: Scientists reveal hidden behaviors of sound waves
An international team of scientists has developed a new analysis of how sound waves behave, revealing surprising effects that have largely been overlooked for decades. In the new paper in Scientific Reports, which was led ...
Phys.org / Extreme weather events may leave rivers unable to rebound
Severe droughts, intense floods, and heat waves are pushing river ecosystems beyond their natural limits of resilience. A review of data on river systems across several continents published in the journal Nature Reviews Biodiversity ...
Phys.org / Optoelectronic synapse shows exceptional photoresponse for neuromorphic vision
Like so much else in nature, the human visual system has both a complex structure and functional efficiency that is difficult for scientists to replicate. The system is both a sensor and a processor, with the eyes and the ...
