Phys.org / Atomic arrays enable negative refraction, bypassing metamaterial limitations
For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the need for artificially manufactured metamaterials.
Phys.org / Bacterial cellulose promotes plant tissue regeneration, study shows
A study has elucidated the mechanism by which bacterial cellulose mediates plant tissue regeneration. The work has been published today in the journal Science Advances and includes collaborations with researchers of the Institute ...
Phys.org / Masquerading moth deploys specialized nanostructures to evade predators
Researchers from Murdoch University and The University of Western Australia found the forewings of the fruit-sucking moth (Eudocima aurantia) have the appearance of a crumpled leaf—but are in fact flat.
Phys.org / Astrophysicists suggest shaded outer disk regions formed Jupiter's largest moons
A pair of astrophysicists with Aix- Marseille Université, CNRS, and Institut Universitaire de France have developed a new theory about the formation of Jupiter's largest moons. In their paper published in The Planetary Science ...
Phys.org / Certain packaging materials can show 70% lower emissions than alternatives
A comprehensive assessment by researchers, including Rafael Auras from Michigan State University, sought to evaluate the potential environmental impacts of replacing polyethylene, or PE, packaging like bags, films and containers ...
Phys.org / Arctic cyclones could be missing link in sea ice depletion models
A new study published in Communications Earth & Environment gives possible insight into the underprediction of sea ice depletion and the formation of Arctic cyclones. Led by Steven Cavallo, a professor in the School of Meteorology ...
Phys.org / Antarctic midge survives extreme cold with unique dormancy strategies
Picture an Antarctic animal and most people think of penguins, but there is a flightless midge, the only known insect native to Antarctica, that somehow survives the extreme climate. How the Antarctic midge (Belgica antarctica) ...
Phys.org / The first experimental observation of an exotic phase of water: Plastic ice VII
In everyday life, we typically encounter water in one of three familiar states—solid, liquid or gas. But there are in fact many more phases, some of which—predicted to exist at high temperature and pressure—are so strange ...
Phys.org / How Earth's early cycles shaped the chemistry of life
A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life. By exposing organic molecules to repeated wet-dry cycles, ...
Phys.org / Hate speech on X rose by 50% after Musk's acquisition, analysis suggests
A new analysis suggests that the rate of hate speech on X was about 50% higher for several months after Elon Musk purchased the social media platform than in prior months, and the amount of bot and bot-like accounts did not ...
Phys.org / Tidal energy measurements help scientists understand Titan's composition and orbital history
Southwest Research Institute (SwRI) scientists are studying Saturn's moon Titan to assess its tidal dissipation rate, the energy lost as it orbits the ringed planet with its massive gravitational force. Understanding tidal ...
Phys.org / Tree rings and fire scars show fewer forest fires burn in North America today than in the past
Fewer wildfires burn in North American forests today than in previous centuries, increasing the risk of more severe wildfires, according to research published in Nature Communications. The findings may seem counterintuitive, ...
