Cambridge, Massachusetts - Ever heard of the planet Vulcan? In the late 1800s, many scientists thought it was real: a hot planet near Mercury (thus named for the god of the forge), whose gravitational pull supposedly caused a wobble in Mercury’s orbit. But in 1915, Albert Einstein killed off this notion, as MIT’s Thomas Levenson recounts in his new book, “The Hunt for Vulcan,” published today by Random House. As Einstein’s calculations showed, Mercury’s orbit fit perfectly with his theory of general relativity, in which gravity merely follows the shape of spacetime — ending any apparent need to believe in Vulcan.

Austin, Texas - Researchers at The University of Texas at Austin have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.
