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 / 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, ...
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 ...
Dialog / Patients are more than participants: What meaningful engagement really looks like—and why it improves health research
When we talk about "patient engagement" in research, it can sound like a slogan on a grant application rather than something that changes people's lives.
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 / 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 / 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 / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
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 / 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 / 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 ...
