C ryptography is a beautiful branch of mathematics which guarantees the art of secret-keeping. In today’s world of big data, there is a serious conflict between utility and privacy. The prime example of this conflict comes from the field of medicine — the abundance of genetic data today makes it possible to imagine a future where medicines can be personalized, but developing this capability requires running algorithms on large scale genetic data which is highly sensitive, and

Graphene, a ‘wonder material’ derived from graphite, promises new revolutions in the field of electronics, computers, solar panels, optics, bioremediation etc. These new horizons in various fields are, however, halted by the low and costly production of graphene. A team of scientists from IIT-Madras has now developed a low-cost method for production of graphene nanoplatelets clearing a major roadblock in the application of graphene in various industries. Graphene is a single-
