    Designing babies: is there any future for gene-edited embryos?

    The world was shocked in 2018 when He Jiankui, a Chinese biophysicist, announced that he had helped to produce two girls whose genetic code he had edited when they had been embryos. His aim had been to tweak a gene that sometimes confers protection against HIV infections. No one had ever used the CRISPR gene-editing tool in reproduction before and it was completely untested in embryos. Scientists around the world condemned the work as wildly premature and possibly dangerous—the Chinese authorities agreed and Dr He was imprisoned for three years. Now, more than six years later, Dr He is back. And he still wants to prevent medical conditions by editing human embryos. But will the world ever be ready for this use of gene editing? Or will newer methods of editing human genes prove more promising? Host: Alok Jha, The Economist’s science and technology editor. Contributors: Emilie Steinmark, science correspondent at The Economist; Chinese researcher He Jiankui; Henry (Hank) Greely of the Stanford Centre for Biomedical Ethics; Panicos Shangaris of King's College Hospital.

    Yann LeCun: the godfather of machine learning is building “a new revolution in AI”

    The launch of R1, an AI model by the Chinese startup DeepSeek, recently sent shockwaves through the technology world. R1 is a “reasoning” model—the most cutting-edge type of large language model (LLM)—and it performs about as well as the best-in-class Western models but for a fraction of the training cost. Like other LLMs, though, it still lacks many of the skills and types of intelligence that human brains achieve. For one, “reasoning” models still have a very limited understanding of the physical world in which they exist. Our guest today wants to get beyond these hurdles. Yann LeCun, chief AI scientist at Meta and a professor at New York University, thinks LLMs are not the answer if we want truly useful personal assistants, humanoid robots and driverless cars in the future. For machine intelligence to get more interactive with the real world, he is fundamentally rethinking how AI models are built and trained. This week, along with six other pioneers of machine learning, Professor LeCun was awarded the Queen Elizabeth Prize for Engineering. He joins Alok Jha, The Economist’s science and technology editor.

    Chromosome 21: the surprising link between Down’s syndrome and Alzheimer’s

    Since the 1980s, the average life expectancy of a person with Down’s syndrome has more than doubled, from less than 30 to well into their 60s. Living longer, though, has revealed a tragic twist—the vast majority of people with Down’s will go on to develop Alzheimer’s disease by the age of 65. That’s because people with Down's syndrome, who have an extra copy of chromosome 21, produce increased amounts of beta-amyloid, a protein that is implicated as a possible cause of Alzheimer’s. To make things worse, people with Down’s syndrome often cannot access the dementia drugs that might help them—doctors are reluctant to prescribe them because people with Down’s haven't been allowed to take part in the clinical trials for Alzheimer’s drugs. People with Down’s think that should change. In doing so, could scientists unlock the mystery of Alzheimer’s itself? Alok Jha, The Economist’s science and technology editor and Emilie Steinmark, our science correspondent, follow the story of Kate Olmstead, who has Down’s syndrome, and her mother, Amy. Emilie also interviews John Hardy, a neuroscientist at University College London who proposed the amyloid hypothesis for Alzheimer’s in the 1990s. Thanks also to Frank Stephens of the Global Down Syndrome Foundation. Transcripts of our podcasts are available via economist.com/podcasts.
