On this week’s show: How physicists are using quantum sensors to suss out dark matter, how rabies thwarts canine vaccination campaigns, and a kickoff for our new series with authors of books on food, land management, and nutrition science
Dark matter hunters have turned to quantum sensors to find elusive subatomic particles that may exist outside physicists’ standard model. Adrian Cho, a staff writer for Science, joins host Sarah Crespi to give a tour of the latest dark matter particle candidates—and the traps that physicists are setting for them.
Next, we hear from Katie Hampson, a professor in the Institute of Biodiversity, Animal Health & Comparative Medicine at the University of Glasgow, about her work contact tracing rabies in Tanzania. Her group was able to track rabies in a population of 50,000 dogs over 14 years. The massive study gives new insight into how to stop a virus that circulates at superlow levels but keeps popping up, despite vaccine campaigns.
Finally, we launch our 2022 books series on food and agriculture. In six interviews, which will be released monthly for the rest of the year, host and science journalist Angela Saini will speak to authors of recent books on topics from Indigenous land management to foods that are going extinct. This month, Angela talks with Lenore Newman, director of the Food and Agriculture Institute at the University of the Fraser Valley, who helped select the books for the series.

Andrew Robinson reviews five of the week’s best science picks.
Spark
Timothy J. Jorgensen Princeton Univ. Press (2022)
The use of electricity in medicine has long been controversial, notes health physicist Timothy Jorgensen. Eighteenth-century polymath Benjamin Franklin applied shocks to paralysed muscles with temporary success. In the 1930s, neurologist Ugo Cerletti pioneered painful but effective electroconvulsive therapy for schizophrenia and depression. Yet even today, “no one is sure exactly how ECT works”, says Jorgensen in his brilliant book. Now, business magnate Elon Musk plans to implant computer chips to treat brain disorders.
The New Fire
Ben Buchanan & Andrew Imbrie MIT Press (2022)
Artificial intelligence (AI) is not like electricity, but like fire, say Ben Buchanan and Andrew Imbrie — academic specialists in emerging technology — in their authoritative, coruscating analysis of its current and future significance. Its potential impact ranges from illuminating to catastrophic, according to three rival and sometimes overlapping views from observers whom they label “evangelists, warriors and Cassandras”. “Three sparks ignite the new fire,” say the authors: data, algorithms and computing power.
Tomorrow’s People
Paul Morland Picador (2022)
“To most of us, the influence of demography on our future is far from obvious,” writes demographer Paul Morland. City dwellers tend to have low fertility, thereby creating an older population and eventually population decline, which could prompt migration and ethnic change, as in today’s United Kingdom — or might not, as in Japan. Morland’s careful book discusses ten indicators, one per chapter: infant mortality, population growth, urbanization, fertility, ageing, old age, population decline, ethnic change, education and food.
Restarting the Future
Jonathan Haskel & Stian Westlake Princeton Univ. Press (2022)
In the past few decades, growth has stagnated in advanced economies. This is odd, given low interest rates, high business profits and a wide belief that we live with “dizzying technological progress”, write economists Jonathan Haskel and Stian Westlake. They argue that the old economic model based on material production fails when it comes to intangible assets — such as software, data, design and business processes — that hinge on ideas, knowledge and relationships. Financial and state institutions must update to cope.
Inequality
Carles Lalueza-Fox MIT Press (2022)
Inequality and its origins will always preoccupy humans. In 2014, biologist Carles Lalueza-Fox led the retrieval of a genome from a European forager’s skeleton more than 7,000 years old; his later studies revealed genetic evidence of “inequality and discrimination in different times and periods”, as he describes in this significant book, written during the pandemic. He concludes by observing that COVID‑19 has had an enhanced impact on poor people, which he anticipates will feature in future genetic studies.
From the beginning, female self-portraitists have chosen to show themselves at work, as if to demonstrate that they could handle a brush as well as male artists.
The Mirror and the Palette: Rebellion, Revolution, and Resilience: Five Hundred Years of Women’s Self Portraits
Even before COVID-19 increased the risks of cognitive impairments, it had been estimated that 152.8 million people globally would be living with dementia by 2050. Yet treatment for Alzheimer’s disease has hardly improved since it was discovered in 1901, notes neurologist and dementia specialist Sara Manning Peskin. Now, most clinical trials tackling dementia are “deeply rooted in molecular data”. Peskin’s powerful study — immersed in her patients’ stories — analyses neurology’s attempt to reach oncology’s molecular understanding.
The Insect Crisis
Oliver Milman Atlantic (2022)
Insect decline is obvious — but hard to quantify. Environmental journalist Oliver Milman suggests a drop of more than 90% in some places, in his vivid alarm call. The causes are unclear, but include habitat destruction by intensive farming, pesticide use and climate change. Insects’ “intricate dance” with Earth’s environment makes them crucial to human food supplies. We should learn to eat them, not meat, suggests Milman: that will help to save them by freeing farmland from crops needed to feed livestock.
Insulin — The Crooked Timber
Kersten T. Hall Oxford Univ. Press (2022)
Insulin was first used to treat human diabetes 100 years ago, after it was isolated by two medical scientists in 1921. Historian of science Kersten Hall describes this transformative event, together with insulin’s development as the first drug produced by genetic engineering and its lucrative exploitation — using a blend of profound research, lively writing and personal knowledge of diabetes. He argues that the history is a tale not of geniuses or saints, but rather one of “monstrous egos, toxic insecurities and bitter career rivalry”.
How to Solve a Crime
Angela Gallop Hodder & Stoughton (2022)
More than a century ago, criminologist Edmond Locard established forensic science on the principle that “every contact leaves a trace”. The field’s current sophistication and contribution to justice would be beyond his “wildest imaginings”, writes forensic scientist Angela Gallop. She tells gripping stories from her own and others’ experience, beginning with thirteenth-century Chinese investigator Sung Tz’u. He identified a farmer’s killer by asking fellow villagers to put their sickles on the ground; flies alighted on one blade bearing traces of blood.
The Sloth Lemur’s Song
Alison Richard William Collins (2022)
Anthropologist and conservationist Alison Richard has been absorbed by Madagascar for half a century. She writes that the country’s “animals and plants offer a wonderful array of rabbit holes down which a person fascinated by the natural world could disappear for a lifetime”. Why, for example, does its largest lemur sing spellbindingly across the treetops with its mate for many minutes? And what environmental conditions created the island’s unique — now disastrously threatened —
