Dialog / A new light-based sensor could help make ultrasensitive disease testing more portable
When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially true for optical biosensing, ...
Phys.org / Saturn-sized exoplanet with Earth-like temperature reveals methane-rich atmosphere
A planet that is about the size of Saturn, but with a temperature more like Earth's, has an atmosphere rich in methane, according to a new study using NASA's James Webb Space Telescope (JWST).
Phys.org / Why promising CO₂-to-fuel catalysts keep falling short of copper
Technology that converts carbon dioxide (CO₂) into fuels and plastic feedstocks using electricity is gaining attention as a core technology in the era of carbon neutrality. In particular, ethylene and ethanol are high-value ...
Medical Xpress / Mental disorders have nearly doubled since 1990, now affecting 1.2 billion people worldwide
Nearly 1.2 billion people worldwide are living with a mental disorder, nearly double the number recorded in 1990. According to a new study, this stark rise has placed mental disorders as the leading cause of disability globally, ...
Phys.org / Evolutionary arms race stretches hawkmoths and flowers to extremes
Long before his days of research, Christian Couch was just a kid marveling at the butterflies in the Florida Museum of Natural History's Butterfly Rainforest. Years later, after enrolling as an undergraduate student at the ...
Phys.org / How does gold keep its glitter? Researchers uncover why it resists tarnish
Gold has been prized for thousands of years for its enduring shine, but Tulane University researchers have discovered that gold's resistance to tarnishing depends on more than its chemistry.
Phys.org / Wildlife is watching us, too—and changing behavior in response
A new large-scale study led by a research team from the Yale Center for Biodiversity and Global Change has found that wildlife responds not only to how humans reshape their habitats, but also to the simple presence of humans—and ...
Tech Xplore / Perovskite/silicon tandem solar cells reach 32.89% certified efficiency with peak-selective passivation strategy
A team of Chinese scientists has developed a new passivation strategy that significantly improves both the efficiency and operational stability of perovskite/silicon tandem solar cells. The study has been published in the ...
Phys.org / Dual-atom fuel cell catalysts break single-peak rule, exposing two optima
Researchers have uncovered a new principle that could accelerate the development of cheaper and more efficient fuel cells by revealing how dual-atom catalysts behave during a key energy conversion reaction. The study, led ...
Phys.org / Bacteria found in artisan cheeses may ease disease
Blessed are the tiny cheesemakers: scientists have mapped out the bacteria responsible for giving three British cheeses their distinct flavor, which may also be beneficial to human health. Scientists in the Food Microbial ...
Tech Xplore / Novel origami pattern turns flat sheets into load-bearing 3D technology
McGill University researchers have discovered a new way to fold flat sheets into smooth, curved shells that can switch from floppy and flexible to stiff and load-bearing on demand. By designing a special origami pattern and ...
Tech Xplore / AI-powered stretchable computing patch can run algorithms directly on the body
A new skin-like computing patch developed at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) can analyze health data using artificial intelligence in an unprecedented way. Unlike today's ...
