Phys.org / Significant grade inflation may be occurring in graduate education, according to decades' worth of data
Analysis of two decades of student data at a large U.S. university suggests that grade inflation exists in graduate education. Researcher Vivien Lee and colleagues at the University of Minnesota, U.S., present these findings ...
Phys.org / Using 'imaginative' AI to survey past and future earthquake damage
Researchers have used artificial intelligence to develop a new tool for assessing earthquake damage, a leap that could ultimately help first responders in making critical rescue decisions, suggests a new study. The team's ...
Phys.org / Cactus catalog could help plant's prickly problem
With almost a third of cacti species threatened with extinction, a new open-access database of cactus ecology and evolution could help scientists and conservationists save species from the brink.
Phys.org / Genomes reveal five E. coli 'armor' types behind most multidrug-resistant bloodstream infections
The first large-scale genetic study of E. coli's protective armor has identified the five capsule types that are responsible for 70% of all multidrug-resistant bloodstream infections in Europe. Researchers, including those ...
Phys.org / Bioelectronic platform enables precise H₂S delivery to cells, turning a toxic gas into a therapeutic tool
A toxic gas known for its "rotten egg smell" has been transformed into a therapeutic tool. A research team at KAIST has developed a technology to precisely control hydrogen sulfide (H2S) using electrical signals, bringing ...
Phys.org / A forest cleanup crew at risk? What hotter Amazon lowlands could mean dung beetles
Dung beetles remove feces from wild animals in forests and thus inhibit the spread of parasites. They work the dung into the soil and thus supply nutrients to plants. They fulfill this task both in European commercial forests ...
Phys.org / Stabilized hybrid photocatalyst boosts artificial photosynthesis efficiency
A hybrid photocatalyst system from Science Tokyo tackles an overlooked flaw in artificial photosynthesis to dramatically improve CO2-to-formate conversion. Unlike conventional designs where light degrades the molecular catalyst, ...
Phys.org / Why some reefs recover faster than others—mathematical model spotlights coral recruitment patterns
Climate-driven disturbances such as marine heat waves are rapidly reducing coral cover and degrading reef ecosystems worldwide. Using a mathematical model, a research team led by Subhendu Chakraborty at the Leibniz Center ...
Phys.org / Turning CO₂ into methanol: Multilayer machine learning speeds up search for better catalysts
Finding high-performing catalysts, which are used to accelerate processes from chemical manufacturing to energy production, can be a slow, expensive process, often relying on years of trial-and-error or massive computational ...
Phys.org / Scalable flow chemistry speeds deuteration of fatty acids with tunable isotope selectivity
The National Deuteration Facility has developed a capability to use a flow chemistry process to increase efficiency, increase production capacity and reduce decomposition in the synthesis of deuterated molecules.
Phys.org / Polymer uses movable molecular rings to overcome durability–degradability trade-off
Modern polymer materials face a fundamental challenge: they must remain strong and durable during use, yet ideally degrade when they are no longer needed. Designing materials that satisfy both requirements has long been a ...
Phys.org / Continued monitoring of sunken Soviet submarine shows ongoing radioactive leakage, but little impact
In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy ...
