Cooled to the Quantum Realm

Levitation of objects sounds like magic, but it is precisely what Arthur Ashkin's optical tweezer won the Nobel Prize for in 2018. An optical tweezer amounts to an intense laser that focuses down to a very small point. Optical tweezers trap an object put at... click to read more

A match made in heaven: Stacking two solar cells boosts their efficiency

The development and realization of clean, renewable energy is one of the significant problems of our time. Over 850 million people do not have access to electricity. We must find a way to deliver it while maintaining a sustainable climate and air pollution standards. Solar... click to read more

How lab-grown blood vessels can help us understand malaria

Blood circulates a hundred thousand times in our body each day to provide nutrients and support to tissues. This circulation is carried out by blood vessels in a highly organized and efficient transport system. Large vessels are somewhat like highways, carrying large volumes of blood... click to read more

Making non-magnetic photons feel a taste for magnetism

Light consists of chargeless particles called photons. While electrons, being charged, get deflected into curved paths when placed in a magnetic field, the chargeless photons do not feel a real magnetic field the same way. Devising an “artificial” or “fictitious” magnetic field for photons would... click to read more

The solid which conducts heat best

Controlling the flow of heat has been one of the earliest technological tasks conceived by humans. Think of putting on clothes and building houses, which emerged well before written communication. However, it was only in the late nineteenth century that the nature of heat was... click to read more
