How ageing happens and whether it can be slowed has recently become the subject of intense research and investment. Scientists are exploring differing approaches to reducing age-related deterioration, tech billionaires are experimenting with as-yet-unproven interventions. It is entirely possible that by 2100, people will typically live to be 100, thanks to a better understanding of the process of ageing. But is there a limit to how far human lives can be extended?

Discussions about artificial intelligence tend to focus on its risks, but there is also excitement on the horizon. AI tools, like the models beneath ChatGPT, are being increasingly used by scientists for everything from finding new drugs and materials to predicting the shapes of proteins. Self-driving lab robots could take things even further towards making new discoveries. As it gets ever more useful, could AI change the scientific process altogether?
Jane Dyson, structural biologist at the Scripps Research Institute in La Jolla, California, explains why Google DeepMind’s AlphaFold tool is useful, but scientists should be aware of its limitations. This week, Google DeepMind released a new tool to unpick the link between genes and disease, as Pushmeet Kohli, head of the company’s “AI for Science” team, explains. Also, Kunal Patel, one of our producers, meets Erik Bjurström, a researcher at Chalmers University of Technology and Ross King, a professor of Machine Intelligence at Chalmers University of Technology and at the University of Cambridge. They explain why self-driving lab robots could make research more efficient. Alok Jha, The Economist’s science and technology editor hosts, with Abby Bertics, our science correspondent and Tom Standage, deputy editor.

Artificial intelligence and biotechnology are at the vanguard of a new era of humanity, according to Mustafa Suleyman. The entrepreneur has been at the forefront of AI development for over a decade and predicts that in the near future, everyone will have their own personal AI assistants that will plan and arrange tasks on their behalf. He also sees an acceleration in the pace of scientific discovery, with AI helping researchers tackle some of the world's grandest challenges—from climate change to famine. But these technologies also come with grave risks. In the hands of bad actors, disinformation could influence elections, or synthetic substances could be weaponised. This week, we explore how to develop the coming technologies responsibly, the hurdles that need to be overcome and how society should prepare for this new age of AI. Alok Jha, The Economist’s science and technology editor, hosts.
Mustafa Suleyman is the founder of Inflection AI. He was also the co-founder of Google DeepMind. His latest book, “The Coming Wave”, explores how to navigate the opportunities and risks of fast-proliferating new technologies

Some sports use different rules and equipment in the women’s game; some do not. We consider the distinction through the lenses of professional football and rugby. Scientific questions of relative performance lead to those of player safety, and ultimately to philosophy: what do varying opinions about changing women’s game reveal about the purpose of sport in society?
Arve Vorland Pedersen, a sports scientist at the Norwegian University of Science and Technology, calculates how football’s pitches and equipment might scale to account for physiological differences. Ross Tucker, a consultant for World Rugby, describes how a trial of a smaller ball might change the game’s mechanics. Lauren Heria, a professional footballer, explains why such meddling is seen as disrespectful by many players. And Emelia Funnell, a researcher at Ida Sports, reveals why ignorance about ACL injuries among women traces back to male cadavers. Host Alok Jha, The Economist’s science and technology editor, is joined by Abby Bertics, our science correspondent (and a former professional volleyball player).

Extreme weather is constantly in the news, but a new factor is just getting warmed up: El Niño. This Pacific Ocean phenomenon can have devastating effects in some parts of the world while benefiting others; it is linked to droughts as well as floods; and this year’s looks like it may be severe.
Maarten van Aalst, a professor of climate and disaster resilience at the University of Twente, explains how the current El Niño will affect the climate in unpredictable ways. Chris Funk, the director of the Climate Hazards Center at the University of California Santa Barbara, looks at global effects that are already under way. Plus, the harrowing tale of Jack Egan, who lost his home to bushfires in Australia during the last El Niño event. Catherine Brahic, The Economist’s environment editor, and our correspondent Rachel Dobbs consider how prepared countries are for this event. Alok Jha, The Economist’s science and technology editor, hosts.

While some people enjoy learning maths, the subject haunts many children throughout school and beyond. But it doesn’t have to be that way. Eugenia Cheng, a mathematician and author of “Is Maths Real?”, explains why, to her, maths is a joyful enterprise. In this interview with Alok Jha, The Economist’s science and technology editor, Eugenia explores how asking seemingly simple questions can uncover deep mysteries beneath the sums. She also argues that education systems should rethink the way that the subject is taught, to encourage curiosity and creativity.
