3D printing was once only known through science fiction, such as Star Trek, the popular 1960s TV series. But inventors and engineers on Earth began experimenting in real life with 3D printing to find faster ways to develop and build prototypes, using computers, ultraviolet lasers, and printable materials. Now, there are many innovative uses for 3D printing. Yet 3D printing has drawbacks. Chemicals used in 3D printing can be toxic, and legal experts are not sure how to protect 3D printing inventions so that others do not steal ideas. Learn how 3D printing works and how we can keep up with the safety, health, and legal challenges that lie ahead.

Trees are essential. They provide water, shelter, and food for millions of plant and animal species, including humans. They deliver proven health benefits, and they capture and store carbon, which combats climate change. Yet trees are in trouble. Forests are struggling to adapt to climate change, and deforestation is a major threat. Recently, researchers and citizen scientists made the surprising revelation that trees communicate with each other through an underground system of soil fungi and other methods. Complex social networks help trees survive and thrive by transferring resources to each other, sending defense signals, communicating with their kin, and more. Meet the tree scientists and learn more of their fascinating discoveries.
