Nature’s Cool Solution In our last post, we examined how Antarctic fish survive freezing waters using antifreeze proteins, which prevent ice formation in their bodies. But what about the opposite case? What if we could make water freeze more easily at slightly warmer temperatures, using less energy? Isabel Pulido solved that puzzle after experiencing firsthand… Continue reading From Frost-Forming Bacteria to Off-Grid Refrigeration:

Ice is Cool!
How Water Freezes (and Why It Matters) Ice—Simple Yet Strange Ever wondered why ice cubes float or why sidewalks become slippery when they’re covered in frost? Ice might seem ordinary, but it’s packed with fascinating mysteries. In our recent post, we introduced Isabel Pulido’s groundbreaking invention, NanoFreeze, which uses special proteins to freeze water at… Continue reading Ice is Cool!
Colder Ice:
Isabel Pulido’s Cool Innovation One afternoon in rural Colombia, Isabel Pulido watched a mother throw away half-eaten beans and rice. The family had no refrigerator—not because they couldn’t afford one, but because they had no reliable electricity. “I realized then that the biggest problem wasn’t just access to power,” Pulido recalls. “It was about food… Continue reading Colder Ice:
