According to a new experiment at a daycare in Finland, proximity and exposure to nature for just one month may be enough to change a child's immune system. Anthony and Jeff discuss whether it is important to enjoy the green during a global health crisis. The, researchers have 3D printed the smallest boat in the world: a 30-micrometer copy of Benchy the tug boat, a well-known 3D printer test object. This boat is so small, it could float down the interior of a human hair. Jeff and Anthony imagine a world where designer vehicles are injected into our bloodstream to deliver medicine.
