Phys.org / The bizarre sex life of mayflies: Micro-CT scans reveal ins and outs of swarm Kamasutra
A new study on mayflies of the genus Ecdyonurus illustrates just how multifaceted and surprising reproductive behavior in nature can be. Entomologists at the State Museum of Natural History Stuttgart (SMNS), using state-of-the-art ...
Tech Xplore / Can AI read papers like a scientist? A new benchmark shows where LLMs fail
To stay up to date and work forward in their fields, scientists must have at their fingertips and in their minds thousands of published studies. Large language models (LLMs) show promise as a tool for exploring the vast scientific ...
Phys.org / Fortified salad packs a healthy punch to meet a growing vitamin B12 need
A pioneering research-industry partnership has used advances in indoor farming technology to grow pea shoots fortified with vitamin B12, opening an exciting route to market for farmers and addressing a major public health ...
Medical Xpress / Vaping: Emerging harms health systems can't ignore
When e-cigarettes first appeared around 2010, they were hailed as a breakthrough: nicotine delivery without the toxic tar and combustion byproducts of traditional cigarettes. Public health bodies cautiously endorsed them ...
Tech Xplore / Report calls for AI toy safety standards to protect young children
AI-powered toys that "talk" with young children should be more tightly regulated and carry new safety kitemarks, according to a report that warns they are not always developed with children's psychological safety in mind. ...
Phys.org / The 'croak' conundrum: Parasites complicate love signals in frogs
Across the animal kingdom, sound is more than communication—it's a signal of survival and success. From birds and primates to insects, fish, and amphibians, animals broadcast acoustic "advertisements" to defend territory, ...
Medical Xpress / Calcium signaling channels regulate neuroinflammation and motivation, research reveals
Northwestern Medicine scientists have discovered how calcium signaling channels in microglia—the primary immune cells of the brain—regulate neuroinflammation and promote the development of behaviors associated with affective ...
Medical Xpress / Six-week virtual program offers early palliative care roadmap for dementia
For an estimated 11% of Americans over age 65 who have dementia and the over 11 million unpaid caregivers supporting them, there is no instruction manual for navigating life after diagnosis. A team of College of Nursing researchers ...
Phys.org / Strange cosmic burst from colliding galaxies shines light on heavy elements
A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely ...
Phys.org / Researchers use AI to develop RNA-based synthetic NAND switch in living cells
An interdisciplinary research team from two working groups at the Center for Synthetic Biology at TU Darmstadt has developed the first RNA-based genetic switch that precisely replicates the logical behavior of a NAND gate, ...
Phys.org / How much do nontargeted analyses really see? A model maps chemical blind spots
In a study published in Analytical Chemistry, researchers from the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences (HIMS) reveal a sobering reality regarding nontargeted chemical analysis. Although ...
Tech Xplore / The AI that taught itself: How AI can learn what it never knew
For years, the guiding assumption of artificial intelligence has been simple: an AI is only as good as the data it has seen. Feed it more, train it longer, and it performs better. Feed it less, and it stumbles. A new study ...
