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!

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:
The Last Clear-Cutting:
How Bottom Trawling is Destroying Earth’s Final Frontier What if bulldozers were clearing ancient forests the size of San Francisco (47 square miles) every day—leveling everything from the historic buildings of Chinatown to the vibrant streets of the Mission District, from the towering redwoods of the Presidio to the protected wildlife areas of the Bay?… Continue reading The Last Clear-Cutting:
The Warming Oceans:
A Global Crisis Heats Up Our planet’s oceans are a testament to nature’s grandeur. They cover over 70% of Earth’s surface, leading us to perceive them as limitless and resilient. However, the BBC reports recent findings reveal a more alarming truth: the world’s oceans are warming at an unprecedented rate, reaching the highest global average… Continue reading The Warming Oceans:

Time to Curb Climate Change Summer has long been a season for fun and relaxation, but the summer of 2023 is proving to be less about picnics and more about sweltering temperatures. According to the National Oceanic and Atmospheric Administration (NOAA), most of the United States is currently swaddled in an embrace of above-average temperatures… Continue reading The Heat is On
