Phys.org / What it would have been like to experience the dinosaur‑killing asteroid armageddon: A blow‑by‑blow account
A great Tyrannosaurus rex strides through the conifer trees of her territory, sniffing the air. She picks up the scent from the carcass of a dead horned dinosaur, Triceratops, that she was feeding on yesterday. She walks ...
Medical Xpress / The robotic penguin that makes endoscopy optional
Researchers at the TechMed Center of the University of Twente have built a swallowable soft robot that samples stomach fluid and measures acidity in real time. The robot has no battery, chip, nor any other electronics. Health ...
Phys.org / Old plant populations offer new clues to climate resilience
When scientists think about how plants will respond to climate change, they often look north. As temperatures rise, many species are expected to shift their ranges toward cooler regions with a loss of populations in warmer ...
Tech Xplore / Copper's biggest rival yet? New carbon nanotube fibers could reshape wiring for EVs, drones and aircraft
Spanish researchers have demonstrated a scalable manufacturing process for carbon nanotube (CNT) fibers with electrical conductivity comparable to that of copper and aluminum. The result, published in Science, is a breakthrough ...
Phys.org / Ganymede's unique magnetic field may be powered by ongoing core formation—not a cooling core
Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon's uniqueness is the fact that among the hundreds of ...
Phys.org / Climate scientist finds large errors in a global climate pollution database
New research from Northern Arizona University found that a global greenhouse gas emissions database produced by the Climate TRACE consortium, co-founded by former Vice President Al Gore, is underestimating vehicle carbon ...
Phys.org / Northern Sri Lanka's oldest confirmed settlement reshapes what archaeologists thought about early island life
A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation ...
Phys.org / Alaska's near‑record landslide tsunami sent a wave 1,580 feet up the fjord walls
On the evening of Aug. 9, 2025, passengers on the Hanse Explorer finished taking selfies and videos of the South Sawyer Glacier, and the ship headed back down the fjord. Twelve hours later, a landslide from the adjacent mountain ...
Phys.org / Generative AI may significantly reduce the number of animal experiments
In early phases of drug development, new active substances are tested in animals—alongside numerous other experimental methods. Researchers face a dilemma: on the one hand, for ethical reasons, they aim to keep the number ...
Phys.org / Chip-scale photonic approach achieves ultralow-noise microwave and millimeter-wave signal generation
Researchers led by Dr. Changmin Ahn and Prof. Jungwon Kim at KAIST, in collaboration with Prof. Hansuek Lee, have demonstrated a chip-scale photonic approach for generating ultralow-noise and highly stable microwave and millimeter-wave ...
Medical Xpress / Engaging with the arts linked to slower aging at the biological level
Regularly taking part in arts activities such as reading, listening to music or visiting a gallery or museum may slow the pace of biological aging, suggests a new study by University College London (UCL) researchers.
Tech Xplore / Contact between 2D and 3D perovskites reshapes crystal order, lifting efficiency to 26.25%
Perovskites, a class of material with a characteristic crystal structure that can convert light into electricity, have proved to be promising for the development of more affordable, flexible, and efficient solar cells than ...
