By carefully arranging molecules, scientists can control how a material responds to light, heat and physical force
University of Missouri researchers have created a single solid material that responds differently depending on what it's exposed to. Shine light on it, and it changes from yellow to white, an indication of a chemical reaction. Heat it, and it undergoes a different chemical reaction. Scratch the surface, and it flashes blue.
We haven't written up this one. Phys.org has the full story — the link below goes straight to it.
