Learn how one company took inspiration from nature to reinvent the robotic arm in this video excerpted from NOVA: “Making Stuff Wilder.” Host and technology columnist David Pogue meets with engineer Heinrich Frontzek to find out about the Bionic Handling Assistant—a machine modeled after an elephant's trunk. A traditional robotic arm is rigid and unable to work closely with humans, but this new design is more flexible and less dangerous. The company has also developed a new kind of adaptive gripper, inspired by fish fins, that is flexible and able to securely grasp even fragile objects, like eggs. This video is available in both English and Spanish audio, along with corresponding closed captions.

This narrated animation from Interactive NOVA: "The Secret of Life" shows the double helix structure of DNA and how the molecule replicates. The segment illustrates how DNA "unzips" to form templates for the new strands and how complementary nucleotides bind together like the rungs of a ladder. This
