In a study published recently in Nature Methods, scientists at The Ohio State University report on a new approach to immobilize extracellular vesicles in a way that mimics their interactions with tissues, a tricky environment compared to bodily fluids because these particles have a specific characteristic: They’re sticking to a surface. The new technique enables label-free immobilization of extracellular vesicles and particles without damaging them, allowing researchers to study them individually or in clumps and observe how they interact with cells.
Drone footage revealed constant violations of Mexico’s whale shark tourism rules, even when far fewer boats were on the water than regulations allow. The findings raise broader questions about whether popular wildlife encounters — from manta rays and sea turtles to whales and even elephants — are truly “ecotourism” and highlight the need for stronger monitoring and community-led stewardship.
Metabolic dysfunction-associated steatotic liver disease (MASLD), a spectrum of liver conditions ranging from simple steatosis to steatohepatitis (MASH), fibrosis, and cirrhosis, represents a global health epidemic with no approved pharmacotherapies.
