Tech Xplore / Optical device uses humidity to unlock hidden information and offers new option for data storage
Engineers at the University of California San Diego have developed an optical device that reveals hidden images and changes colors in response to different levels of humidity. The technology, published in Light: Science & ...
Phys.org / Ancient dust points to retreat of West Antarctic Ice Sheet during last warm period
Antarctica's Ross Ice Shelf and the West Antarctic Ice Sheet may have been far smaller during one of Earth's most recent warm periods, according to a new study that traced the origin of ancient dust preserved in Antarctic ...
Medical Xpress / Social media bans for teenagers lack evidence and pose risks, scientists say
Bans on teenagers' social media use are gathering pace worldwide. Their proponents claim that social media bans will improve young people's mental health, but what evidence supports these claims? In their new Frontiers in ...
Phys.org / Supercharging solar cells: Quantum dot-molecule hybrid states enable near-maximum efficiency
Solar panels have become more efficient over the years, but even the best designs still lose a large fraction of the energy they absorb. Scientists around the world have been searching for ways to capture more energy from ...
Medical Xpress / Celiac disease may raise risk of heart attack, stroke and early death
People with celiac disease and dermatitis herpetiformis have a slightly increased risk of cardiovascular disease, certain types of blood cancer, and premature death. This is shown by a large U.S. registry study led by researchers ...
Phys.org / Fire salamanders reveal hidden turquoise glow when exposed to UV radiation
An international research team has discovered that the fire salamander (Salamandra salamandra) is biofluorescent. A study published in the journal Royal Society Open Science shows that the salamander reflects turquoise light ...
Phys.org / Discovery of furtivovirus advances understanding of giant virus evolution
In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. This model suggests that every living organism can be traced back to a distant common ancestor. However, ...
Phys.org / Tiny on-chip circuit could power next-generation quantum and AI technologies
Researchers from Monash University have developed a breakthrough nanoscale circuit that can generate, direct, and read light-based information, all on a single chip.
Tech Xplore / Physics-aware AI generates more realistic sounds by estimating mass and velocity from video
When people watch a scene in the film "Jurassic Park" where a giant dinosaur walks toward them, they naturally imagine a heavy, rumbling sound, as if the ground were shaking. This is because humans predict sound by considering ...
Phys.org / An AI solution to an 80‑year‑old problem has shocked mathematicians
Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul ...
Medical Xpress / Stress before conception may reprogram sperm and boost male offspring growth
Research from the University of Colorado Anschutz suggests that stress experienced by a father before conception may influence an offspring's growth by altering small molecular signals in sperm. The study, published in iScience, ...
Medical Xpress / RNA therapy for genetic heart failure moves closer to patients after lab gains
Using patient-derived cardiac tissue and stem cell-based models, the team of translational researchers demonstrated that targeting the genetic cause of disease improved cellular abnormalities and identified the biological ...
