Phys.org / Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
Phys.org / Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion
Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace ...
Phys.org / An iconic spear-throwing device likely wasn't used by prehistoric hunters until around 10,000 years ago
Archaeologists have long pictured prehistoric hunters taking down mammoths and other megafauna using the atlatl, a handheld spear-throwing device that uses leverage to achieve greater velocity and force when throwing darts. ...
Phys.org / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / Walkable, greener neighborhoods linked to better physical and mental health across the U.S.
A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents—especially when cities provide walking opportunities, greenery and mixed-use streets with a blend of commercial and residential ...
Tech Xplore / New 4D-printing method creates lighter, faster-spinning wind turbine blades
A new manufacturing technique developed by Concordia researchers could make small wind turbines lighter, less expensive and easier to produce. Using a process known as 4D printing of composites, Ph.D. candidate Emad Fakhimi ...
Phys.org / Fish in a polluted Mexican river may mate with the wrong species, leading to hybrid offspring
The byproducts of modern society appear to be messing with the love life of two tiny fish species that have long coexisted in Mexican rivers.
Tech Xplore / When wind turbines become visible, support for renewable energy can decline
The expansion of renewable energy is a cornerstone of climate policy. While wind energy is widely supported in principle, people living near wind turbines often experience the local consequences of the energy transition directly. ...
Phys.org / Abandoned farmland restored to wildflower meadow without sowing seeds
Abandoned farmland can be transformed into wildflower-rich grassland habitat without the need for expensive and labor-intensive seeding, a new study by UCL researchers finds.
Phys.org / Himalayan pangolin emerges as distinct species, confirmed with DNA from 19th-century specimen
The pangolin is a midsize mammal found only in Africa and Asia. The pangolins' scales make them unique, but these scales have become their undoing. Pangolins are poached for their scales, making them the most highly trafficked ...
Medical Xpress / A blood protein can flag dementia risk decades before symptoms appear
Forgetting the name of a loved one may be one of the first signs people notice of dementia, but it's rarely the first warning sign your brain gives. Changes in the brain that lead to neurodegenerative diseases like Alzheimer's ...
