Phys.org / Children and monkeys share common understanding of geometry
With their ability to use tools, remember faces and even learn how to communicate with humans through sign language, nonhuman primates are considered to be among the smartest creatures on Earth. However, some concepts—geometry, ...
Phys.org / What explains gender pay gaps in academia?
Gender pay gaps in academia are well documented. The harder question is why they persist. A new study published in the Proceedings of the National Academy of Sciences tested several leading answers to that question.
Tech Xplore / Mechanical engineers develop buttons that rise with light
No wires. No actuators. Shine light on the metal surface, and it rises like a button. KAIST researchers have developed a metal structure that changes shape using light, without any light-absorbing coating. This technology ...
Phys.org / Arctic winter sea ice returns to significant decline, ending the temporary slowdown
New analysis shows that a "pause" in Arctic winter sea ice decline seen in the early 2020s has ended following record lows in 2025 and early 2026. The study, led by the University of Southampton in collaboration with the ...
Phys.org / Japan's first mosasaur premaxilla fossil hints at a new species
A research team from Okayama University of Science, Tokyo City University, the Natural History Museum, Kishiwada City (Osaka Prefecture), and other institutions has identified four previously unrecognized fossil bones from ...
Tech Xplore / Programmable metasurface turns keyboard commands into dynamic holograms in milliseconds
Metasurfaces are ultrathin optical components engineered with arrays of nanoscale structures that can control light in ways that are difficult for conventional optics. Unlike traditional optical components, which typically ...
Tech Xplore / Hybrid-electric aircraft clears 30,000 feet for first time in test flights
An aircraft powered by a megawatt-class hybrid-electric engine developed in collaboration with NASA and built by GE Aerospace, demonstrated flight of an innovation that can inform new generations of fuel-saving aircraft power ...
Phys.org / Heat shock reveals rapid protein-control system cells may use to survive
The planet is getting hotter, and life will need to adapt to rising temperatures to survive. One way cells adapt to changing conditions is by synthesizing new proteins. That works well when the environment changes slowly, ...
Phys.org / AI may not make us stupid, but relying on it could weaken the skills built through practice
The worry of becoming stupid isn't new; it dates back to the time of the Greek philosopher Socrates, who insisted that writing would destroy memory and weaken the mind. Then came calculators, GPS and computers, all of which ...
Medical Xpress / A new plan for healthy aging starts before we're born
Most of us would like to hang around on the planet for as long as possible, and thankfully, lifespans in many countries are increasing. Scientists are also developing a new field known as longevity medicine, which aims to ...
Medical Xpress / Severe flooding linked to increased deaths from opioid use in rural Appalachia
Severe flooding may contribute to higher mortality rates from opioid use in rural Appalachia, according to a study by researchers at Penn State. The findings—published in the Proceedings of the National Academy of Sciences—are ...
Medical Xpress / Flexible clocks can sync up or drift apart across brain regions in mice
A study in mice suggests the brain does not rely on a single internal clock but can flexibly switch between shared and independent timing across regions, as reported by researchers from Science Tokyo. By recording thousands ...
