| Turning physics on its earIt's a pivotal moment. The invention, at its very least, could moderately improve the efficiency of induction motors, used in everything from electric cars to ceiling fans. At best it means a way of tapping the mysterious powers of electromagnetic fields to produce more work out of less effort, seemingly creating electricity from nothing. |
| Artificial letters added to life's alphabetTwo artificial DNA "letters" that are accurately and efficiently replicated by a natural enzyme have been created by US researchers. Adding the two artificial building blocks to the four that naturally comprise DNA could allow wildly different kinds of genetic engineering, they say. |
| Doctors Report Transplant BreakthroughIn what's being called a major advance in organ transplants, doctors say they have developed a technique that could free many patients from having to take anti-rejection drugs for the rest of their lives. |
| The Future of Artificial IntelligenceIn the first of a two-part conversation, host Steve Curwood sits down with famed inventor and futurist Ray Kurzweil to look at some of his inventions and discuss the future of artificial intelligence. Kurzweil says that "the singularity" is near - a time when we will merge with our technologies, and greatly expand our human potential. |
| Local teams construct robots, block by blockSeventy teams of 9- to 14-year-olds from across Iowa, Nebraska and Missouri will use computer programs to control LEGO robots capable of completing energy-related tasks, such as setting up wind turbines and attaching solar panels to roofs. |
