Tech Xplore / Danish chemist's invention could make counterfeiting a thing of the past
Every year, companies lose revenue when goods are copied or illegally resold. Now, a new digital and legally binding fingerprint developed at the University of Copenhagen makes products impossible to counterfeit. Royal Copenhagen ...
Phys.org / System can diagnose infections in 20 minutes, aiding fight against drug resistance
A new technique which slashes the time taken to diagnose microbial infections from days to minutes could help save lives and open up a new front in the battle against antibiotic resistance, researchers say.
Phys.org / Commercially viable biomanufacturing: Designer yeast turns sugar into lucrative chemical 3-HP
Using a tiny, acid-tolerant yeast, scientists have demonstrated a cost-effective way to make disposable diapers, microplastics, and acrylic paint more sustainable through biomanufacturing.
Phys.org / X-ray spectra provide sharpest image to date of a rapidly spinning black hole
The X-Ray Imaging and Spectroscopy Mission (XRISM), a joint mission between the Japanese Aerospace Exploration Agency (JAXA) and NASA, launched on Sept. 7th, 2023. Its advanced imaging filters and spectrometers were designed ...
Phys.org / Engines of light: New study suggests we could increase useful energy obtained from sunlight
Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one of science's oldest challenges—how to turn heat into useful energy.
Phys.org / A case of mistaken identity: Mammoth fossils from Alaska turn out to belong to two ancient whales
For more than 70 years, what were thought to be mammoth fossils were tucked away in the archives of the University of Alaska Museum of the North. During the museum's Adopt-a-Mammoth program, which allows the public to sponsor ...
Phys.org / Laser pulse 'sculpting' unlocks new control over particle acceleration
In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work with the highest possible focused laser peak power, which is the ratio of energy per unit area ...
Tech Xplore / Perovskite solar cells maintain 95% of power conversion efficiency after 1,100 hours at 85°C with new molecular coating
Scientists have found a way to make perovskite solar cells not only highly efficient but also remarkably stable, addressing one of the main challenges holding the technology back from widespread use.
Phys.org / Scientists map development of pancreas transport channels that deliver digestive enzymes
Organs often have fluid-filled spaces called lumens, which are crucial for organ function and serve as transport and delivery networks. Lumens in the pancreas form a complex ductal system, and its channels transport digestive ...
Phys.org / Important new source of oxidation in the atmosphere found
Hydroperoxides are strong oxidants that have a significant influence on chemical processes in the atmosphere. Now, an international research team involving the Leibniz Institute for Tropospheric Research (TROPOS) has shown ...
Medical Xpress / How your brain keeps time: Consistent probability calculations help you react rapidly
Humans respond to environments that change at many different speeds. A video game player, for example, reacts to on-screen events unfolding within hundreds of milliseconds or over several seconds. A boxer anticipates an opponent's ...
Medical Xpress / Popular omega-3 supplements fail to improve depressive symptoms in young people
Fish oil pills rich in omega-3 fatty acids gained attention as a possible add-on treatment for depression, as a few studies on adults found noticeable improvements in symptoms when combined with antidepressants.
