A new bioinspired sponge-like gel shrinks single-handedly, squeezing unspecialized cells inside it and turning them into cells that begin to form teeth. The new material was inspired by the embryo’s power to shape organs, and it could enable engineering of new teeth, bone, or other tissues, scientists report.
The first direct, temporally resolved observations of intermediate steps in water oxidation using cobalt oxide, an Earth-abundant solid catalyst, revealed kinetic bottlenecks whose elimination would help boost the efficiency of artificial photosynthesis systems.
A new chemical synthesis for alpha-arylated Carbonyl derivatives was developed. Members of this class of substances typically possess interesting biological and pharmacological properties and often find applications as medicines. The new technique allows such carbonyl derivatives to be generated easily and in an environmentally friendly manner.
