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 / Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way
Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...
Phys.org / NASA delays the first Artemis moonshot with astronauts because of extreme cold at the launch site
NASA has delayed astronauts' upcoming trip to the moon because of near-freezing temperatures expected at the launch site.
Phys.org / Sprint or marathon? Aging muscle stem cells shift from rapid repair to long-term survival
Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein ...
Phys.org / AI systems could identify math anxiety from student inputs and change feedback
Math anxiety is a significant challenge for students worldwide. While personalized support is widely recognized as the most effective way to address it, many teachers struggle to deliver this level of support at scale within ...
Phys.org / Cosmic radiation brought to light: Researchers measure ionization in dark cloud for the first time
Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation shows how charged high-energy ...
Phys.org / Innate biases of newborn animals inspire adaptive decision-making model
Precocial animals, the ones that move autonomously within hours after hatching or birth, have many biases they are born with that help them survive, finds a new paper led by Queen Mary University of London, published in Proceedings ...
Medical Xpress / Dementia research must include voices of those with lived experience
A new Canadian study has found that people living with dementia (PLWD) are often excluded from research due to assumptions of incapacity and variations in institutional processes. The authors argue that with rights-based, ...
Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena
The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...
Phys.org / Removing livestock from grasslands could compromise long-term soil carbon storage
Removing sheep and other livestock entirely from upland grasslands—a strategy often promoted as a way to boost carbon storage and tackle climate change—may actually reduce the most stable forms of soil carbon, according ...
Tech Xplore / Your future home might be framed with printed plastic
The plastic bottle you just tossed in the recycling bin could provide structural support for your future house. MIT engineers are using recycled plastic to 3D print construction-grade beams, trusses, and other structural ...
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 ...
