Researchers kept vegetables fresh without refrigeration by injecting them with melatonin using biodegradable microneedles. “This is the first time that we’ve been able to apply these microneedles to extend the shelf life of a fresh-cut crop,” Benedetto Marelli says. https://news.mit.edu/2025/new-technology-extends-produce-shelf-life-0521 (fb)

MIT is taking cues from worms, turtles, and even jellyfish to build the next generation of machines. These bio-inspired bots are smaller, softer, and smarter, designed to navigate tight spaces and adapt like nature’s own engineers. From disaster zones to deep-sea exploration, the future of robotics is looking wildly organic. (fb)
