Phys.org / Caribbean rainfall driven by shifting long-term patterns in the Atlantic high-pressure system, study finds
A new study published in Science Advances overturns a long-standing paradigm in climate science that stronger Northern Hemisphere summer insolation produces stronger tropical rainfall. Instead, a precisely dated 129,000-year ...
Phys.org / Tiny lead fragments in hunted meat exceed safe levels, study reveals
This fall, when Adam Leontowich headed to southeast Saskatchewan to hunt whitetailed deer and ruffed grouse, he once again opted for lead-free ammunition—cartridges with copper bullets for his .308 rifle and shells with ...
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 / Can quantum computers help researchers learn about the inside of a neutron star?
A new paper published in Nature Communications could put scientists on the path to understanding one of the wildest, hottest, and most densely packed places in the universe: a neutron star.
Phys.org / Electric control of ions and water enables switchable molecular stickiness on surfaces
What if a surface could instantly switch from sticky to slippery at the push of a button? By using electricity to control how ions and water structure at the solid liquid interface of self-assembled monolayers of aromatic ...
Phys.org / Stars defy black hole by showing stable orbits around Sagittarius A*
An international research team led by PD Dr. Florian Peissker at the University of Cologne has used the new observation instrument ERIS (Enhanced Resolution Imager and Spectrograph) at the Very Large Telescope (VLT) facility ...
Phys.org / Long-term field data reveal warming cuts temperate forest NO and N₂O emissions by altering soil moisture
Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences and the University of California, Riverside, have investigated how the loss of forest soil gaseous nitrogen (NO, N2O, and N2) is affected ...
Phys.org / Physicists generate hybrid spin-sound waves, expanding options for 6G implementation
Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists at RPTU have now shown ...
Phys.org / Quasi-periodic oscillations detected in unusual multi-trigger gamma-ray burst
A new study led by the Yunnan Observatories of the Chinese Academy of Sciences has detected quasi-periodic oscillation (QPO) signals in an unusual gamma-ray burst (GRB) event. The findings are published in The Astrophysical ...
Phys.org / Advanced tracking uncovers flapper skate hotspots on Scotland's deep seabed
Flapper skate (Dipturus intermedius), the world's largest skate species measuring over two meters in length, live hidden on the rugged seabed around Scotland. Their life in the darkness, deep underwater, makes it extremely ...
Phys.org / Curiosity and focus found to set 'genius' dogs apart in object learning
Curiosity might have killed the cat, but it could prove to be one of the keys to dogs' cognitive abilities, according to a study by the University of Portsmouth's Dog Cognition Center in England and the Friedrich Schiller ...
Phys.org / Male skulls at Shimao gate rewrite story of Neolithic human sacrifice
A new study published in Nature on November 26 has shed light on the origins, population structures, and kinship systems of the people of Shimao—one of China's most significant late Neolithic settlements. Analyses of ancient ...
