Notch signalling is best known for its role in lateral inhibition, where it acts to prevent differentiation of cells neighbouring one that has 'won out' in a competition to differentiate. Recent results suggest that Notch signalling can work in the opposite way, and promote differentiation of the receiving cells.

The haptic hand is a greatly simplified robotic hand that is designed to mirror the human hand and provide haptic force feedback for applications in music. The “fingers” of the haptic hand device are laid out to align with four of the fingers of the human hand. A key is placed on each of the “fingers” so that a human hand can perform music by interacting with the keys. The haptic hand is distin...
