The frigid conditions on the surface of Saturn’s largest moon, Titan, allow simple molecules in its atmosphere to break one of the most fundamental rules in chemistry, a new study shows. According to this principle, known as “like dissolves like,” mixtures containing both polar and nonpolar components, such as oil and water, usually don’t mix and instead form separate layers. …

A groundbreaking study of nearly 800 pet dogs has uncovered a group of molecules that could redefine how we understand aging. These elusive compounds, found in canine blood, are offering scientists a glimpse into the molecular mechanics of longevity. The findings open a new frontier linking the health of dogs and humans in the shared pursuit of a longer, better …

Space keeps a record of chemistry that started long before Earth formed. Carbon bonds with hydrogen, oxygen, nitrogen, and sulfur to build “organic molecules,” and those compounds show up all over the place. Telescopes and spacecraft find them in comet gases, in interstellar dust, and in primitive rocks. This matters because planets can inherit those ingredients instead of making everything …

This article was originally published at Eos. The publication contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. New laboratory research suggests that some organic molecules previously detected in plumes erupting from Saturn’s moon Enceladus may be products of natural radiation, rather than originating from the moon’s subsurface ocean. This discovery complicates the assessment of the astrobiological relevance of …

Scientists Discover Food Molecules That Trick Cells Into Staying Young  SciTechDaily Longevity research: Dietary stress supports healthy aging  Medical Xpress Bacterial RNA promotes proteostasis through inter-tissue communication in C. elegans  Nature Source link

Summary: Living longer doesn’t always mean living healthier, and researchers are exploring how diet can extend healthspan. A study in worms shows that specific dietary RNA molecules protect cells from harmful protein build-up, a major driver of aging and age-related disease. These RNAs activate stress responses and autophagy, enhancing resilience and slowing cellular aging across the body. While still early-stage …

Complex organic molecules that form part of the chain of chemical reactions that can result in life’s building blocks have been found in the watery geysers of Enceladus, almost twenty years after the plumes were first sampled by NASA’s Cassini spacecraft. Cassini‘s mission to the ringed planet Saturn ended in 2017, but scientists are still making findings buried deep in …
