In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

Just over 125,000 years ago, humanity was going extinct until a dramatic shift occurred—Homo sapiens started tracking the tides in order to eat the nearby oysters. Before long, they’d pulled themselves back from the brink of extinction. What saved us during that period of endangerment? The...

The extraordinary story of how the human brain evolved… and is still evolving. We’ve come a long way. The earliest human had a brain as small as a child’s fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is...

How four tools enabled humanity to control its destiny What enabled us to go from simple stone tools to smartphones? How did bands of hunter-gatherers evolve into multinational empires? Listeners of Sapiens will say a cognitive revolution - a dramatic evolutionary change that altered our brains, turning primitive humans into modern ones - caused a cultural explosion. In Transcendence, Gaia Vince argues instead that modern humans are the product of a nuanced coevolution of our genes, environment, and culture that goes back into deep time.

Many people believe that, at its core, biological sex is a fundamental, diverging force in our development. According to this familiar story, differences between the sexes are shaped by past evolutionary pressures - women are more cautious and parenting-focused, men seek status to attract more mates - re-created in each generation by sex hormones and male and female brains. This, in turn, is the basis of supposedly entrenched inequalities in our modern societies.

We have lost the war on cancer. We spend $150 billion each year treating it, yet - a few innovations notwithstanding - a patient with cancer is as likely to die of it as one was 50 years ago. Most new drugs add mere months to one's life at agonizing physical and financial cost. In The First Cell, Azra Raza offers a searing account of how both medicine and our society (mis)treats cancer, how we can do better, and why we must.
