The study found that increasing the consumption of methionine restored reproductive function.

BBC News - Scientists hail robotic hand 'breakthrough'
For one month, Italian scientists demonstrated that a person could control a robotic hand using only neural signals from the nerves in his arm, and was able to perform complex tasks. He was also able to detect sensations in his hand because the link was designed to be two-way. Visit the link to see a video of him controlling the hand.

Paper screens could provide depth to computer display - tech - 03 December 2009 - New Scientist
The paper has targets that are reflective in the infrared, allowing the position and orientation of the paper to be tracked to within 1 cm. The positional data of the paper is then used to change the image being projected onto the paper, giving it the illusion of allowing you to see slices of a 3D space.
