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 / 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 ...
Phys.org / New plastics designed to degrade on demand may help address global waste
Yuwei Gu was hiking through Bear Mountain State Park in New York when inspiration struck. Plastic bottles littered the trail and more floated on a nearby lake. The jarring sight in such a pristine environment made the Rutgers ...
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 / Group 13 elements: The lucky number for sustainable redox agents?
Researchers from The University of Osaka created a reagent for important building-block molecules with an abundant main-group element, gallium. These early findings show that an organic gallium compound can display transition-metal-like ...
Phys.org / The largest ice desert has the fewest ice nuclei worldwide
There are fewer ice nuclei in the air above the large ice surfaces of Antarctica than anywhere else in the world. This is the conclusion reached by an international research team led by the Leibniz Institute for Tropospheric ...
Phys.org / Nanoscale 'Bragg gratings' on photonic chips suppress noise in laser light
Researchers at the University of Sydney have cracked a long-standing problem in microchip-scale lasers by carving tiny "speed bumps" into the devices' optical cavity in their quest to produce exceptionally "clean" light. ...
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 / Astronomers unveil 400 sibling star clusters in the Milky Way
Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide insight into how stars form ...
Phys.org / 'Stick and glue' method enables more precise biomolecule tracking in cells
A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent ...
Phys.org / Rare stone tool cache found in Australian outback tells story of trade and ingenuity
About 170 years ago, a large bundle of stone tools was deliberately buried close to a waterhole in the remote Australian outback. Who buried them and for what purpose? Why were they never retrieved?
