Phys.org / From single queens to mega-colonies: How ant societies are shaped by the environment
A single queen in the tropics; large colonies in deserts; workers with uniform morphology in temperate regions; ant social structures vary according to environmental conditions. This is shown, for the first time at a global ...
Phys.org / 2024 total eclipse subtly shifted animal calling across three Ohio prairies, study finds
No natural phenomenon provides a rarer chance to study the secrets of the animal world than a total solar eclipse. This was recently demonstrated by researchers investigating how a total solar eclipse might affect the soundscape ...
Medical Xpress / Spray away infections: New device delivers antibiotics via mist, alleviating risks of side effects
A University of Missouri researcher has unveiled a safer, smarter way to fight drug-resistant infections. Dr. Hongmin Sun, an associate professor in the School of Medicine, has demonstrated that a spray-mist device can deliver ...
Phys.org / Bubble bots: Simple biocompatible microrobots autonomously target tumors
The potential of microrobots is enormous. These miniature objects can be designed to carry out actions within the body, such as sensing biomarkers, manipulating objects like blood clots, or delivering drug therapies to tumor ...
Tech Xplore / Unhackable metasurface holograms: Security technology can lock information with light color and distance
A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure hologram platform that operates solely based on the wavelength of light and the spacing between metasurface ...
Phys.org / Platinum nanostructure sensor can differentiate mirror-image volatile scent compounds
Terpenes are volatile organic compounds that are responsible for, among other things, the typical scents of plants, resins or citrus fruits. These compounds occur naturally in the environment and influence chemical processes ...
Phys.org / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Phys.org / Challenging California's water 'scarcity' narrative
California doesn't have a water scarcity problem. It has a distribution problem, according to Nícola Ulibarrí, whose new research is reshaping how policymakers think about one of the state's most pressing challenges.
Phys.org / How lipid nanoparticles carrying vaccines release their cargo
A study from FAU has shown that lipid nanoparticles restructure their membrane significantly after being absorbed into a cell and ending up in an acidic environment. Vaccines and other medicines are often packed in little ...
Phys.org / Could ionospheric disturbances influence earthquakes?
Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert electrostatic forces within Earth's crust and potentially contribute to the initiation of large ...
Phys.org / From sea to space: Turning the tide on microplastic pollution with satellite technology
What do microplastics, water color, and satellites have in common? Dr. Karl Kaiser, professor of marine and coastal environmental science in the College of Marine Sciences and Maritime Studies at Texas A&M University at Galveston ...
Phys.org / New mineral sunscreen reduces white cast by using tetrapod-shaped zinc oxide
UCLA researchers have developed a mineral sunscreen formulation that significantly reduces the white, chalky cast that keeps many people from wearing sun protection daily. For decades, dermatologists have urged people to ...
