Secret messages hidden in light-sensitive polymers

Scientists from the CNRS and Aix-Marseille Université have recently shown how valuable light-sensitive macromolecules are: when exposed to the right wavelength of light, they can be transformed so as to change, erase or decode the molecular message that they contain.

What forces enable trees to stand upright?

To develop straight, plants require a motor system that controls their stance by creating powers to counterbalance gravity. Researchers have long imagined that this...

Polymers that mimic chameleon skin

Natural tissues have complex mechanical properties – delicate yet-solid, extreme yet-adaptable – that are hard to recreate utilizing engineered materials. A universal group has...
