Nearly everyone has had to sit a standardised test at some point in their lives and felt the grip it might hold over their future—and not always in a good way. André Rupp, research director at ETS, the nonprofit company that runs some of the most well-known tests, talks us through what's going on at the forefront of research and the new kinds of tests that are being developed.

Contemporary physics is so complex that no single physicist can be said to have a decent grasp of the full picture. This makes communicating physics a formidable challenge.  Acclaimed popular science writer, Jim Baggott, talks us through this challenge by discussing his favourite physics books.

The ‘subterranaut’ describes how the discovery of ancient bacteria miles beneath the Earth’s surface opens the possibility of finding life on Mars. He picks five books that show how our knowledge of life deep in this planet could lead us to discover it elsewhere.

When dealing with epidemics, science does not have all the answers and relying on a new miracle drug is not always the solution. We must also learn the lessons of history, argues the veteran doctor of the HIV/Aids epidemic, Arthur Ammann. He picks the best books on ‘plagues.’

The term 'eugenics' elicits queasiness amongst those who associate it with the Nazis. But Winston Churchill, George Bernard Shaw and Margaret Sanger were among its many proponents in the interwar period. Why? Philippa Levine, professor of history at the University of Texas, explains.

What role did culture play in human evolution? Why did human brains get so big so quickly? When and why did inequality first emerge in human society? Harvard professor and author Joe Henrich picks some of the best books for understanding 'cultural evolution.'

When addressing the really fundamental questions in science, researchers must assume that there is an objective reality to describe. But the nature of that reality may be more subtle, allowing space for the existence of God, says Andrew Briggs, professor of nanomaterials at Oxford University.

Public understanding of radiation needs to improve if people are to properly assess its benefits and risks argues author and academic, Timothy Jorgensen. From the discovery of radio to a cancer cluster in New Jersey, he chooses highly readable books illuminating different aspects of radiation.

Children learn in many different ways and the best science books for young people reflect that, says science writer Alice Bell. She recommends some of her favourite science books for kids.

The professor of quantum information theory at Oxford tells us about books that successfully popularise quantum physics and the science of complex systems. Look, no equations!
