Phys.org / What's that swirly pattern? It's a moiré, and it has potential power
Just as wave-like patterns can appear on a computer screen when pixels do not align, new research led by Flinders University is investigating atomic-scale "moiré patterns" in the promising field of ferroelectricity. The new ...
Phys.org / Archaeological digs in Amazon provide clues about Indigenous inhabitants before colonization
Paving roads in the Amazon rainforest has long brought deforestation that threatens the people who live there. The same roadwork, however, has also allowed archaeologists to get glimpses of the region's past long before Europeans ...
Phys.org / Molecular chains unlock atomically precise nanoribbons for next-generation electronics
Scientists have developed a unique way to build electronic components so small they are made from chains of individual molecules—creating a toolbox to help build materials that could power the next generation of technology.
Phys.org / Nuclear war at Ukraine-Russia border could trigger years of global climate disruption and radioactive fallout
Geopolitical tensions in Eastern Europe underscore the urgency of addressing the climate and radiological consequences of a regional nuclear conflict. Even a small-scale nuclear conflict at the Ukraine–Russia border could ...
Phys.org / Amazon River plume: Where microalgae go carnivorous to win
In the vast plume of the Amazon River, microscopic algae adopt a surprisingly flexible survival strategy: They combine photosynthesis with the uptake of organic matter. An international research team led by the Leibniz Institute ...
Phys.org / Scientists discover how the Twelve Apostles were formed—and their real age
Scientists at the University of Melbourne have uncovered for the first time how Australia's iconic Twelve Apostles were formed, finding tectonic plate movements over millions of years lifted and tilted the giant structures ...
Phys.org / This flower's toxic traits hold clues for safer drugs
The molecules of a highly toxic plant, known for its bell-shaped purple and pink flowers and found in some home gardens, have long been used to regulate human heart muscles.
Phys.org / Black grouse eye test reveals best flags to protect birds from fatal cables
There is a silent killer lurking in the French Alps: ski lift cables. Over the last 60 years, the wires have accounted for almost 600 recorded landfowl deaths in the region. Black grouse (Lyrurus tetrix) account for ~70% ...
Phys.org / Gene-sharing view challenged as bacteria shown to police DNA exchange
A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view ...
Phys.org / From air to tea: New sensor reveals invisible pollution in minutes
Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.
Phys.org / Honeybees pass their math test, upending an animal intelligence debate
We've run the numbers and the verdict is in: Honeybees do have the ability to process numerical information. New research led by Monash University has now addressed recent international debate over whether bees are truly ...
Phys.org / How an Atlantic island narrowly escaped 'stealthy' eruption
Thousands of earthquakes affecting Portugal's São Jorge Island in the Azores in March 2022 were triggered by a vast sheet of magma (molten rock) rising from more than 20km below Earth's surface and stalling just 1.6km beneath ...
