Most likely, you’re aware of 3D printing, which allows you to design and produce one-of-a-kind pieces for a variety of purposes. But what if you could use that same technology to manufacture biological materials, like new tissue or blood vessels? Welcome to the world of 3D biomanufacturing, a... Read More

Centuries ago, large, wooden ships explored the seven seas. But often a ship that began its voyage with a crew of hundreds could return with tens. The silent killer? Scurvy, a disease that occurs when there’s a lack of Vitamin C in the diet. On the other extreme, explorers of the North and South... Read More

While 3D printers are technology that many people are familiar with, there’s one 250 miles above us on the International Space Station (ISS) that’s unlike anything currently found on Earth. It’s known as the Refabricator, a hybrid 3D printer that can recycle its hard, polymer plastic numerous times... Read More

Did you ever notice how the air can seem cooler when you enter a forest? Humans aren’t the only living things that sweat to cool off. When trees and plants “sweat,” they cool themselves andcan cool the surrounding air.Through a process called transpiration,water and nutrients are taken up by plant... Read More

The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More
