Inspiration can come at any time. One evening, Jessica Jackley went to hear Mohammed Yunus, founder of the Grameen Bank and modern microfinance, who was giving a talk at her business school. He spoke about the power of microcredit to change lives and help people with little money but big hopes become entrepreneurs. Excited by… Continue reading How to Test Drive Your Social Impact Idea

From Frost-Forming Bacteria to Off-Grid Refrigeration:
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:
Antifreeze Proteins:
Antarctic Fish Surviving Sub-Zero Waters We started this series by exploring Isabel Pulido’s NanoFreeze technology. Her breakthrough made refrigeration possible in areas without reliable electricity. This change enabled communities to preserve food for days, saving time, money, and work. NanoFreeze also helped reduce pollution and made it easier to ship goods like food and medicine… Continue reading Antifreeze Proteins:
Uncommon Ice
Different Types of Ice Learning about Isabel Pulido’s NanoFreeze technology, which is helping preserve food in rural Colombia, led me to take a closer look at the science of freezing. At first, it seemed simple—ice is just frozen water. But I soon found out that water can actually freeze into nearly 20 different solid forms,… Continue reading Uncommon Ice
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!
Henrietta Swan Leavitt:
The Woman Who Helped Us Measure the Universe In the early 1900s, measuring distances in space was one of astronomy’s greatest challenges. We knew there were other galaxies out there, but we had no reliable way to determine how far away they were. Enter Henrietta Swan Leavitt, an American astronomer whose brilliant discovery would forever… Continue reading Henrietta Swan Leavitt:
Supertasters:
How an Explosion Revealed a Taste Talent “It’s just a matter of taste,” you might say to a friend when debating your favorite foods. But what if it’s more than personal preference? Science reveals that some people experience tastes more intensely than others. People with a heightened ability to taste are called supertasters. These individuals… Continue reading Supertasters:
AI Analysis Finds Elephants May Voice Names
Have you ever wondered if animals are capable of more complex communication than we typically give them credit for? While we often think of calls and cries as simple utterances, emerging research suggests some species may employ vocal systems similar to human language and naming conventions. One of the most fascinating examples comes from a… Continue reading AI Analysis Finds Elephants May Voice Names
Heman Bekele and his Skin Cancer Fighting Soap
“The average price of skin cancer treatment in the U.S. is almost $40,000, but my bar of soap only costs $8.50 to create, and it can replicate the same effects as something that people pay thousands and thousands of dollars for.” Heman Bekele, a 14-year-old ninth grader from W.T. Woodson High School in Annandale, Virginia,… Continue reading Heman Bekele and his Skin Cancer Fighting Soap
A Trigonometry Proof of the Pythagorean Theorem?
Impossible? Not for Them! Calcea Johnson and Ne’Kiya Jackson, two high school students from New Orleans, astonished mathematicians by proving the Pythagorean theorem using trigonometry. Many mathematicians thought a trigonometric proof of this foundational theorem of geometry was not possible without using circular reasoning. Jackson and Johnson, however, created one. The Pythagorean theorem, a cornerstone… Continue reading A Trigonometry Proof of the Pythagorean Theorem?
