Fireworks in a flask

Peering down the neck of a round-bottom flask reveals crystals that look like the finale of a firework show spreading across a night sky. Nikhil Gaikwad, a research scholar at the National Institute of Pharmaceutical Education & Research, Hyderabad, came across these crystals of a chlorinated pyrrolopyrimidine while synthesizing potential anticancer agents. He generally uses dichloromethane to crystallize and purify his compounds after a chlorination reaction, but this time, Gaikwad decided to use chloroform. Instead of getting the usual needle-shape crystals, he was surprised to find these branching starbursts.—Manny Morone

It may be hard for an egg to turn into bird: it would be a jolly sight harder for it to learn to fly while remaining an egg. We are like eggs at present. And you cannot go on indefinitely being just an ordinary, decent egg. We must be hatched or go bad. -C. S.
