My cat can smell depression. Another family cat could smell my stepfather’s dementia. They both became more affectionate and tactile: the dementia-smelling cat would gently paw my stepfather, when he hadn’t even liked her when he had been well. My cat comes in close when my mood is darker. Perhaps both cats were using other cues, but I’m convinced it was smell. Up until the 18th century, doctors relied for diagnoses on smell as much as anything else For something that Jonas Olofsson calls ‘the easiest and most natural thing in the world’, smell is satisfyingly complicated. When it comes to humans’ ability to smell, as Olofsson persuades us in

Is this what it felt like in the months before August 1914? Or during the years leading up to September 1939? The discussion around artificial intelligence produces a deep foreboding that we are in the grip of forces largely beyond our control. Are we sleepwalking towards disaster? That is the feeling I have after reading Genesis, a collaboration by Eric Schmidt, the former CEO of Google, Craig Mundie, the former chief research and strategy officer at Microsoft, and Henry Kissinger, who died, aged 100, soon after completing this book. They have crafted a holistic analysis of the social, political, psychological and even spiritual impacts that a superior machine intelligence would

Versailles was a palace of science, as Anna Ferrari shows in this stimulating and innovative study, accompanying a dazzling exhibition of the same title at the Science Museum, London (until 21 April). Soldiers were subjected to electricity experiments in the Galerie des Glaces. The king watched the dissection of an elephant or a horse in the Menagerie. The latest globes and clocks, microscopes and barometers, miracles of precision and beauty, were, and in some cases still are, on display in the royal apartments. The gardens were exercises in trigonometry and hydraulics as well as planting. Louis XV had the largest and most varied plant collection in Europe. On 19 September

What do you do when one of your possessions goes missing? Search behind the sofa cushions? Ask other members of the household where they put it? If you lived in Renaissance England, there’s a chance you would have consulted a local magician for advice, especially if the lost item was of value. In the absence of police to investigate theft or insurance to cover a loss, a wizard tracing the item seemed like a fair choice. Nor was it the entirely foolish idea it might seem now. In a time when belief in magic was widely held, making it known that a magician was on the case could prompt a

At the core of Paul Carlucci’s debut novel is a protracted medical experiment conducted by one human on another. Set on the Canadian frontier of the 1830s and inspired by historical record, the book takes the strange case of Dr William Beaumont’s tests on Alexis St Martin’s digestive system and spins a marvellously dark yarn around them, exploring the uses and abuses of an innocent. Alex is the innocent in question – the voyageur of the title. Our journey with him starts in raw boyhood, finding him living at the back of a Quebec harbour storehouse. His mother is dead, his beloved petit frère also. His grief-stricken father has sailed

‘I can’t quite believe I’m here, having a steak dinner with a killer,’ writes Jenny Kleeman, as she sits with a hitman for the big opening to her book about the price we put on life. Someone paid to take lives is about to spill the beans on his dark trade. There should be tension. There should be jeopardy. We should be worried about Kleeman’s safety. So why does it feel a bit flat? It is difficult to find a hired gun, obviously. This one is John Alite, who was ‘a hitman for the Gambino dynasty’. However, he is now ‘a motivational speaker’ and ‘host of several podcasts’, and seems

While I was reading Most Delicious Poison, I visited a herbal garden in Spain which features the plants grown by the Nasrid rulers of Granada hundreds of years ago. They cultivated myrtle for its medicinal uses and jasmine for its fragrance. How did they know of myrtle’s properties? Some ancient ancestor must have figured it out. And that ancestor might be more ancient than we realise. Noah Whiteman explains that DNA from plants found in Neanderthals’ teeth tartar suggests even they were self-medicating with herbs. We have been entangled with the chemicals around us for as long as we have been human. The author of this book, a professor of

Now is a difficult time to empathise with Russians – which is why we need Maxim Osipov. We need him to bring alive to us what it means to live in Putin’s Russia – how the system finds ways to crush all but a very few. Even more, we need him to remind us of the kaleidoscope of qualities that a country like Russia inevitably contains – the humanity and generosity as well as the stupidity and cruelty. An author of great subtlety, Osipov would no doubt wince at such grandiose claims for his writing. Yet when the world is deciding how to deal with the aftermath of Putin’s (eventual,

When Ray Bradbury was asked if his dystopian vision in Fahrenheit 451 would become a reality, he replied: ‘I don’t try to predict the future. All I want to do is prevent it.’ In the hot embers of the Covid-19 pandemic, it may not be enough to foresee infectious disease threats if we lack the ability to forestall them. After all, predictions were made about 2019. In a Ted talk four years earlier, Bill Gates warned about what he later called ‘Disease X’, a respiratory disease that would cause millions of fatalities. Devi Sridhar, a professor of public health at the University of Edinburgh, addressed the Hay Festival in 2018

If you were a teenager before 2005, one reminder of tuberculosis in British life is that small circular scar on your bicep. Maybe you’ve explained to your children why it’s there, if you ever knew. The BCG is no longer a routine vaccination in the UK, a revision which signalled to many that TB was over. What used to be known as consumption became treatable, preventable and ostensibly consigned to medical history as a threat of the past. We tell stories about diseases as if they are constant things. ‘It’s no worse than flu’ has become a familiar phrase; but flu is not all that common, it varies wildly in
