Phys.org / 3D-printed rattlesnake reveals how the rattle is a warning signal
A team of researchers from The University of Texas at El Paso has uncovered new evidence explaining why the rattlesnake's rattle—one of nature's most iconic warning signals—has persisted and proven so effective across ...
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 ...
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 / AI search robot uses 3D maps and internet knowledge to find lost items
A robot that can locate lost items on command, the latest development at the Technical University of Munich (TUM), combines knowledge from the internet with a spatial map of its surroundings to efficiently find the objects ...
Medical Xpress / Mobile clinics offer a practical way to improve health care access in maternity care deserts
Only three of the 14 counties in north-central Florida provide full access to obstetric care. Six have low access to care—meaning there are fewer than two hospitals offering obstetric care or birth centers per 10,000 births ...
Phys.org / A new model defines an upper limit to planetary radiation belt intensity
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby ...
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 ...
Medical Xpress / Antibiotics can affect the gut microbiome for several years, study shows
Antibiotic treatments can affect the composition of the community of bacteria living in the gut, known as the gut microbiome, for a long time. A new study shows that certain types of antibiotics can be linked to changes in ...
Phys.org / Simple 'cocktail' of amino acids dramatically boosts power of mRNA therapies and CRISPR gene editing
Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution. Researchers are racing to use them ...
Phys.org / Strontium optical clock accurate to within 1 second over 30 billion years
Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and uncertainty both surpassing ...
