Scientists Grow Body Parts in the Lab
Watching human organs take shape in a lab dish is no longer the realm of science fiction: as scientists get better at applying engineering techniques to living cells and tissues, lab-grown organs are increasingly becoming a reality. And this week, researchers at Wake Forest University report that they have for the first time successfully created a urethra that worked in human patients.

Molecular Robot Programmed to Follow Instructions
Scientists have developed a programmable "molecular robot" - a sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions programmed into a set of fuel molecules determining its destination, for example, to turn left or right at a junction in the track. The report, which represents a step toward futuristic nanomachines and nanofactories, appears in ACS's Nano Letters.

World's First Feasible 'Artificial Leaf'
A practical artificial leaf that can turn sunlight and water into energy as efficiently as the real thing has long been a Holy Grail of chemistry, and researchers at MIT may have finally done it. Today at the National Meeting of the American Chemical Society researchers from MIT's Nocera Lab, led by Dr. Daniel Nocera, claimed that they've created an artificial leaf made from stable and - more importantly - inexpensive materials.

3-D Printing Method Advances Antenna Design
While most electronic components benefit from decreased size, antennas suffer limitations in gain, efficiency, system range, and bandwidth when their size is reduced below a quarter-wavelength.
