Trailer: The Modi Raj

5/29/2024
Narendra Modi is one of the most popular politicians on the planet. India’s prime minister is eyeing a third term atop the world’s biggest democracy. A tea-seller’s son, Mr Modi began life an outsider and the man behind the political phenomenon remains hard to fathom. India has become an economic powerhouse during his ten years in charge. But he’s also the frontman for a chauvinistic Hindu nationalist dogma. Can Mr Modi continue to balance both parts of his agenda and finish the job of turning India into a superpower? The Economist’s Avantika Chilkoti finds out what makes him tick. Launching June 2024. To listen to the full series, subscribe to Economist Podcasts+.

Babbage: Teens and their screens

5/1/2024
Ever since there have been smartphones and social media, there have been concerns about how they might be affecting children. Over the past decade, doctors have seen a decline in mental health in the young in much of the rich world. But whether that rise can be attributed to technology is still a matter of fierce debate. Nevertheless, demands are growing to proactively restrict teenagers’ access to phones and social media, just in case. How concerned should parents and teachers be? Or is this just another moral panic? Host: Alok Jha, The Economist’s science and technology editor. Contributors: Tom Wainwright, The Economist's technology and media editor; Clare Fernyhough, co-founder of Smartphone Free Childhood; Carol Vidal of Johns Hopkins University; Pete Etchells, a psychologist at Bath Spa University and the author of “Unlocked: The Real Science of Screen Time”.

Babbage: The science that built the AI revolution—part one

3/6/2024
What is intelligence? In the middle of the 20th century, the inner workings of the human brain inspired computer scientists to build the first “thinking machines”. But how does human intelligence actually relate to the artificial kind? This is the first episode in a four-part series on the evolution of modern generative AI. What were the scientific and technological developments that took the very first, clunky artificial neurons and ended up with the astonishingly powerful large language models that power apps such as ChatGPT? Host: Alok Jha, The Economist’s science and technology editor. Contributors: Ainslie Johnstone, The Economist’s data journalist and science correspondent; Dawood Dassu and Steve Garratt of UK Biobank; Daniel Glaser, a neuroscientist at London’s Institute of Philosophy; Daniela Rus, director of MIT’s Computer Science and Artificial Intelligence Laboratory; Yoshua Bengio of the University of Montréal, who is known as one of the “godfathers” of modern AI. On Thursday April 4th, we’re hosting a live event where we’ll answer as many of your questions on AI as possible, following this Babbage series.

Babbage: The hunt for dark matter

2/21/2024
Dark matter is thought to make up around a quarter of the universe, but so far it has eluded detection by all scientific instruments. Scientists know it must exist because of the ways galaxies move and it also explains the large-scale structure of the modern universe. But no-one knows what dark matter actually is. Scientists have been hunting for dark matter particles for decades, but have so far had no luck. At the annual meeting of the American Association for the Advancement of Science, held recently in Denver, a new generation of researchers presented their latest tools, techniques and ideas to step up the search for this mysterious substance. Will they finally detect the undetectable? Host: Alok Jha, The Economist’s science and technology editor. Contributors: Don Lincoln, senior scientist at Fermi National Accelerator Laboratory; Christopher Karwin, a fellow at NASA’s Goddard Space Flight Center; Josef Aschbacher, boss of the European Space Agency; Michael Murra of Columbia University; Jodi Cooley, executive director of SNOLAB; Deborah Pinna of University of Wisconsin and CERN.

Babbage: Fei-Fei Li on how to really think about the future of AI

11/22/2023
A year ago, the public launch of ChatGPT took the world by storm and it was followed by many more generative artificial intelligence tools, all with remarkable, human-like abilities. Fears over the existential risks posed by AI have dominated the global conversation around the technology ever since. Fei-Fei Li, a pioneer that helped lay the groundwork that underpins modern generative AI models, takes a more nuanced approach. She’s pushing for a human-centred way of dealing with AI—treating it as a tool to help enhance—and not replace—humanity, while focussing on the pressing challenges of disinformation, bias and job disruption. Fei-Fei Li is the founding co-director of Stanford University’s Institute for Human-Centred Artificial Intelligence. Fei-Fei and her research group created ImageNet, a huge database of images that enabled computers scientists to build algorithms that were able to see and recognise objects in the real world. That endeavour also introduced the world to deep learning, a type of machine learning that is fundamental part of how large-language and image-creation models work.

Babbage: How to avoid a battery shortage

10/25/2023
In the coming decades, electric vehicles will dominate the roads and renewables will provide energy to homes. But for the green transition to be successful, unprecedented amounts of energy storage is needed. Batteries will be used everywhere—from powering electric vehicles, to providing electricity when the sun doesn’t shine or the wind doesn’t blow. The current generation of batteries are lacking in capacity and are too reliant on rare metals, though. Many analysts worry about material shortages. How can technology help?

Babbage: The mystery of chronic pain

10/18/2023
Chronic pain is thought to affect around a third of people. For one in ten of these, the pain is severe enough to be disabling—making it the leading cause of disability worldwide. Some forms of chronic pain are particularly mysterious—with clinicians unable to treat the pain, nor understand its causal mechanisms—presenting a huge challenge for societies. How can this burden be eased, for both healthcare systems and the individuals living with pain? Host: Alok Jha, The Economist’s science and technology editor, with Gilead Amit, our science correspondent. Contributors: Catherine Charlwood, who lives with chronic pain; Francis Keefe, director of the Pain Prevention and Treatment Research Program at Duke University; Matt Evans, a clinical lecturer at Chelsea and Westminster Hospital and Imperial College London; Jan Vollert, a pain researcher at the University of Exeter.

Babbage: How AI promises to revolutionise science

9/20/2023
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.

Babbage: Mustafa Suleyman on how to prepare for the age of AI

9/13/2023
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.

Babbage: Sex differences and sport

9/6/2023
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.

Babbage: The race to the Moon’s South Pole

8/16/2023
In the coming days, both Russia and India hope to land robotic probes near the South Pole of the Moon. Conquering the South Pole remains one of the grandest challenges in lunar science, but it’s a potentially rewarding endeavour. If evidence of water is found it will make human settlements much more likely. But the significance of the missions racing for the Moon, Luna-25 and Chandrayaan-3, go beyond science. Russia’s space agency has become isolated after the country’s invasion of Ukraine, while India’s space agency seeks to raise its profile. In an increasingly polarised world, is there any hope for an international agreement on humanity’s use of the Moon? Sam Dayala, a former director at the Indian Institute of Space Science and Technology and India’s space agency, explains the aims of Chandrayaan-3. Simeon Barber, a planetary scientist at the Open University who works with the European Space Agency, discusses Russia’s Luna missions and why his drilling package has been removed from the Luna-27 probe. Natan Eismont of the Russian Academy of Sciences explains his desire for renewed global collaboration, despite the political backdrop. Plus, Asif Siddiqi of Fordham University and Raji Rajagopalan of the Observer Research Foundation, reflect on the stakes if a consensus on the use of the Moon isn’t agreed internationally.
