In this week's segment we will learn about experiments that are being performed by a robot scientist. We will also find out about new and improved artificial muscles.
The Very Small and the Very Old
The small world of nanotechnology is making a big splash this summer with water repellent swimsuits. Also, our human ancestor Peking Man finds out he is much older than we thought.
Technology Old and New: Silk Production and Paper Diagnostics
Hear how China may not have held the ancient patent on silk production technology. Also, discover future ways that paper technology can help diagnose patients, even outside of medical facilities.
Helpful Bee Stings | Prehistoric Primates
Although bee stings can be painful and possibly harmful, discover how the toxin may also be able to help kill cancer cells. Then, find out if ancient primates Ida and Afradapis are our cousins or our ancestors.
The Secret Life of Robotic Bees
Spying, exploring, pollinating. These are just some of the many uses for robotic bees. Hear how a wide range of scientists and engineers at Harvard University are designing a mechanical form of this social insect.
Bomb Detecting Nanosensors | Listeria Outbreak
Dr. Daniel Heller from MIT describes how he uses nanosensors and bee venom to detect explosives. PhD candidate Kyle Perry from Harvard gives the facts about the recent Listeria outbreak connected to cantaloupes.
