Phys.org / Tiny reconfigurable robots can help manage carbon dioxide levels in confined spaces
Vehicles and buildings designed to enable survival in extreme environments, such as spacecraft, submarines and sealed shelters, heavily rely on systems for the management of carbon dioxide (CO2). These are technologies that ...
Phys.org / Radio wave bursts linked to onset of intense auroral storms
A University of Southampton study has revealed an intriguing new clue in the mystery of what triggers periods of very intense, brightly colored activity during displays of both the southern and northern lights.
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 / 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 / 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 ...
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 / Nanostructured coatings physically puncture bacteria to prevent biofilm formation
Bacteria that multiply on surfaces are a major headache in health care when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon ...
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 / 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 / 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 ...
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 ...
