Adam Rutherford Weidenfeld & Nicolson (2022)

When Charles Darwin’s cousin, Francis Galton, coined the word eugenics in 1883, he called it the study of the conditions under which “men of a high type are produced”. This gross idea led to the gates of Auschwitz, reminds broadcaster Adam Rutherford (an alumnus of the Galton Laboratory, former name of University College London’s human‑genetics centre). It hasn’t gone away, he explains in his timely salvo on the politics and history of notions that dog genetics, events up to and after the ‘CRISPR twins’ and the resurgence of white supremacy.

Dark and Magical Places

Christopher Kemp Profile/Wellcome Collection (2022)

“I have no sense of direction,” confesses molecular biologist Christopher Kemp — unlike his wife, “an effortless and intuitive navigator”. Once, in a mirror maze, he was transfixed with alarm, and had to be pulled out by his seven-year-old son. Many others experience similar disorientation, sometimes with disastrous results, as when hikers get lost. Their stories vitalize this compelling study of the brain, memory and navigation, in which one psychologist compares our understanding of parts of the brain with knowledge of black holes.

When the World Runs Dry

Nancy F. Castaldo Algonquin (2022)

Globally, millions of people must walk up to 6 kilometres daily to get clean water, says environmental writer Nancy Castaldo. Moreover, each year, more children die as a result of water contamination than from violence, including war, said the United Nations in 2019. Castaldo’s alarming book discusses many examples of shortages and tainting, ranging from drought in Cape Town, South Africa, to lead pollution in Flint, Michigan. She concludes with realistic steps to reduce domestic consumption and contamination.

Making Numbers Count

Chip Heath and Karla Starr Avid Reader (2022)

Business scholar Chip Heath and science journalist Karla Starr are familiar with the need to “translate numbers into instinctive human experience”, informatively and memorably. Unable to find a book on the subject, they decided to write their own. Their diverse guide bubbles with translated statistics. For example, there are about 400 million civilian-owned firearms in the United States — that translates into one for every adult and child, with around 70 million left over.

Genetically Modified Democracy

Aniket Aga Yale Univ. Press (2021)

India’s 1960s Green Revolution began without much deliberation. The government promoted high-yielding varieties of wheat and rice, and guaranteed purchase prices. This helped “already well-off, landed farmers”, notes environmentalist Aniket Aga, but led to huge debts for the struggling majority. When genetically modified crops reached India in 2002, they cultivated much more scrutiny, involving scientists, seed companies, farmers, consumers and the state. Aga describes the debate, without claiming to provide an answer.
