Tech Xplore / Three holographic layers steer red, green and blue light for brighter AR displays
Researchers have developed a full-color near-eye display that uses three stacked holographic gratings, each engineered to direct red, green or blue light. The new design could help advance compact, energy-efficient augmented ...
Phys.org / Genomics used to find endangered fish populations most vulnerable to climate change
Scientists have shown that genomics can help identify which wild populations are most vulnerable to climate change—offering practical guidance for conserving threatened species before declines become irreversible.
Medical Xpress / Testing finds 85% of everyday personal care products contain unlabeled chemicals with suspected health hazards
A new study of sunscreens, baby lotions, shampoos, soaps and other everyday products found that nearly all contained chemicals not disclosed on their labels. Most contained at least one unlabeled chemical with known or suspected ...
Phys.org / Beauty by contrast: How hair color and background color influence skin appearance
Skin appearance plays an important role in the perception of age, health and attractiveness. Of course, skin appearance is affected by actual skin condition, but previous research has also found that it is affected by adjacent ...
Phys.org / Webb reveals oxygen-rich dust and water surviving near Milky Way's central black hole
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers has discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the center of the Milky ...
Phys.org / Early farmers' larger grains may reflect rainfall, not genetic selection
A new archaeobotanical study by researchers from the University of Oxford and Kiel University (CAU) has revealed that increases in cereal grain size at the dawn of agriculture, more than 11,000 years ago, were initially driven ...
Medical Xpress / Mapping how mental health risks emerge in AI chatbot conversations
Scientists at UCL have developed a framework for stress-testing how AI chatbots respond to vulnerable users, helping researchers identify weaknesses and test ways to make mental health interactions safer.
Phys.org / Want a happier marriage? Study suggests one simple habit
Research has long shown that exercise benefits both physical and mental health. Now, a new study from researchers at BYU suggests that it may also strengthen marriages, especially when couples exercise together.
Phys.org / Genetic neighborhoods distinguish harmful poultry bacteria from harmless strains
When it comes to identifying harmful bacteria, it helps to look at the company their genes keep. Researchers with the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas Division of Agriculture, ...
Medical Xpress / Computational framework identifies novel pathway for asthma inflammation
Researchers at Columbia University Mailman School of Public Health, in collaboration with investigators at the University of Chicago, have developed a new computational framework that helps scientists identify genes that ...
Phys.org / Real-time X-ray data analysis with DONUT accelerates materials science
What if scientists could get a taste of discovery as soon as their experiment finishes? Thanks to a new machine learning tool called DONUT, researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory ...
Tech Xplore / Today's downloads predict tomorrow's scientific impact—up to five years out
The trail of likes, shares and downloads we leave across the internet could help predict successful innovations years in advance, Cornell researchers showed by curating two datasets that allowed them to compare early engagement ...
