Okay, so the title is a bit of a lie. Again. But scientists did manage to grow eyes on the side of tadpoles' heads. Which pretty much makes them mutants. Why did they do this to the poor baby frogs? Well, it revealed an entirely new form of control over the formation of organs in the body. By altering voltage gradients, they were able to produce eyes in parts of the body that would never normally have eyes. While this may not have any clinical applications, it is an interesting find in the world of embryology.
Nanorobots were also new to the world in December. These are small (<1mm) machines that can be steered using magnets to the right place in the giant 3D maze of the circulatory system to detect disease and deliver the drugs needed. They have been in the pipeline since 2007, but development started in December last year.
In other science: 2 earth size exoplanets and 1 hospitable exoplanet in the Kepler system (Kepler-20e, 20f, and 22b respectively); engineers at MIT make a camera with 1 trillion frames per second, fast enough to capture light travelling across surfaces, and a potential vaccine for HIV goes into production.
