Phys.org / From hyperbolic in-plane anisotropy to an optical chirality: A new route to nanoscale circular polarizers
In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered nature allows stacking, ...
Medical Xpress / An existing, FDA-approved drug could stem the spread of breast cancer
Cancer spreads (metastasizes) when tumor cells shed from a primary solid tumor (for example, in the breast) and embed in other organs, such as the lung, liver, and brain, and begin to grow. Most approaches to prevent this ...
Phys.org / Physicists discover long-predicted 'clock magnetism' in an atomically thin crystal
Strange things happen to materials when you peel them down, layer by layer, from thick chunks all the way to sheets just an atom thick. Reporting in the journal Nature Materials, a team led by physicists at The University ...
Phys.org / BaSi₂-supported nickel catalyst boosts low-temperature hydrogen production
A new catalyst strategy developed at Institute of Science Tokyo uses BaSi2 as a support for nickel and cobalt to decompose ammonia at lower temperatures. By forming unique ternary transition metal–nitrogen–barium intermediates ...
Phys.org / DNA study uncovers continental origins of Britain's Bronze Age population
When ancient DNA studies began to gain attention, little more than a decade ago, the view took hold among geneticists that everything we thought we knew about the peopling of Europe by modern humans was wrong. The story was ...
Tech Xplore / Simulated cats and elephants with touch-based memory help usher in new age of robotics
A new approach to simulating biologically inspired robotics can cut the design and training of tactile robots from eighteen months to two weeks, new research suggests. Published in Cyborg & Bionic Systems, the study applies ...
Phys.org / Rainfall can shape bird populations as much as temperature, global study reveals
Scientists have long focused on rising temperatures to understand how climate change is reshaping the natural world. But there's a critical blind spot in that picture: rain. A new global study reveals precipitation has been ...
Phys.org / 'Old Mother Goose' challenges a 14-million-year lineage story in New Zealand
The discovery of a rare fossil goose in an ancient Central Otago lake shows the evolutionary history of Aotearoa New Zealand birds is much more dynamic than once thought, a University of Otago–Ōtākou Whakaihu Waka researcher ...
Medical Xpress / Bacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut-specific antibodies can react so differently. It turns out the answer may be in the mouth and gut's bacteria. A new study, led by researchers ...
Phys.org / Large land predators were hunting big plant-eaters more than 280 million years ago, study finds
A study examining fossil evidence shows that large land predators were already hunting big plant-eating animals more than 280 million years ago. University of Toronto Mississauga researchers Jordan M. Young, Tea Maho, and ...
Phys.org / Less traffic, less noise: Green axes cut noise levels in cities
The implementation of green axes and the reduction of motorized traffic in cities is effectively consolidating itself as a strategy to significantly lower environmental noise levels. A study conducted in the city of Barcelona ...
Phys.org / A translation vanished: Why Ljuba Metzl may be missing from theater history
The Neo-Latin theater play "Cenodoxus" (1602) by Jakob Bidermann is now only known to some researchers in Latin and German studies. But from 1930 to 1960, the story about the battle between heavenly and hellish powers for ...
