Molecular machines are nano-scale assemblers that construct themselves and their surroundings into ever more complex structures. They're widely misunderstood, so let's separate the science fact from science fiction.
Stanford scientists have created designer electrons that behave as if they were exposed to a magnetic field of 60 Tesla—a force 30 percent stronger than anything ever sustained on Earth. The work could lead to a revolution in the materials that make everything from video displays to airplanes to mobile phones.
The Blue Morpho butterfly shines such a brilliant blue it almost seems electric. Its secret? Microscopic holes that play with light in an incredible way. And by using nanotechnology, we can replicate those same effects on printed objects, like money. Bling!
