Here's what you'll learn when you read this story:

• While the modern world is build with cement, its creation is one of the biggest emitters of greenhouse gasses. As a result, finding ways improve its durability and safety is paramount.

• In a new study from Princeton University, scientists turned toward the humble oyster and its iridescent composite material nacre for design inspiration.

• Matching the characteristics of nacre at the microscopic level, the researchers were able to increase the toughness of cement some 17 times, as compared to a cement block on its own.

Scientists are always looking for ways to make inherently brittle materials, such as concrete or ceramic, tougher, safer, and more durable. This time, they found inspiration from one of the most unlikely of places—the extra-durable shells of oysters.

Once again, mother nature provides.
