Novel hydrogels can safely remove graffiti from vandalized street art (5 minute read)

A team of Italian scientists has created a hydrogel that can remove paints from other paints of similar chemical composition. It can be used to repair street art that has been vandalized. The hydrogel is in the form of a thin foil sheet that can be cut into whatever shape is required. It adheres easily to vertical surfaces and will make over-paint soften enough to wipe off after just a few minutes. The gel can be tuned to work on a variety of surfaces.

Need a New Tooth? Drug Discovered to Regenerate Lost Teeth (4 minute read)

Japanese scientists have discovered a monoclonal antibody that can stimulate tooth growth in mice suffering from a congenital condition called tooth agenesis. The fundamental molecules for tooth growth also modulate the growth of multiple organs and tissues very early in development. Suppressing the Uterine Sensitization Associated Gene-1 (USAG-1) benefits tooth growth. The scientists discovered a monoclonal antibody that disrupts the interaction of USAG-1 and another molecule involved in tooth growth. A single administration of the antibody was enough to generate a whole tooth.
