Researchers at the University of Vermont have discovered two new proteins on red blood cells that confirm the testable existence of two new blood types. It's an important discovery, one that'll greatly reduce the risk of incompatible blood transfusions among tens of thousands of people. But what we were more struck by in this press release was the fact that these two new blood types--named Junior and Langereis--bring the total number of recognized blood types up to 32. 32!
Automakers are already mass producing cars that will parallel park themselves, but the rudimentary sensor-based systems on the latest Lexus or Buick have nothing on Junior. The Stanford Racing Team's autonomous car can throw itself into reverse, jam the accelerator to the floor, and slam on the brakes at 25 miles per hour, sliding sideways into a parking space in a display that would make the Duke boys proud.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
