Back in 2001, immunologist Pere Santamaria was exploring a new way to study diabetes. Working in mice, he and his collaborators developed a method that uses iron oxide nanoparticles to track the key immune cells involved in the disorder.
But then Santamaria, who is at the University of Calgary in Canada, came up with a bold idea. Maybe he could use these particles as a therapy to target and quiet, or even kill, the cells responsible for driving the disease — those that destroy insulin-producing islet cells in the pancreas. It seemed like a far-fetched idea, but he decided to try it. “I kept doing experiment after experiment,” he says. Now, more than two decades later, Santamaria’s therapy is on the cusp of being tested in people. It’s not alone. Researchers have been trying for more than 50 years to tame the cells that are responsible for autoimmune disorders such as type 1 diabetes, lupus and multiple sclerosis. Most of the approved therapies for these conditions work by suppressing the entire immune response. This often alleviates symptoms but leaves people at elevated risk of infections and cancers.

Switching between languages, we may feel as if we are stepping from one world into another. Each language seemingly compels us to talk in a certain way and to see things from a particular perspective. But is this just an illusion? Does each language really embody a different worldview, or even dictate specific patterns of thought to its speakers?

Scientists and philosophers sometimes advocate pretty outrageous-sounding ideas about the fundamental nature of reality. (Arguably I have been guilty of this.) It shouldn’t be surprising that reality, in regimes far away from our everyday experience, fails to conform to common sense. But it’s also okay to maintain a bit of skepticism in the face of bizarre claims. Philosopher Eric Schwitzgebel wants us to face up to the weirdness of the world. He claims that there are no non-weird ways to explain some of the most important features of reality, from quantum mechanics to consciousness.
Normally at Five Books we ask experts to recommend the best books in their field and talk to us about them in an interview, either in person, by phone or via Zoom. In January 2023, we asked the AI bot, ChatGPT, to recommend books to us on the topic of AI. Being an AI doesn’t necessarily make the chatbot an expert on AI books, but we thought it might have some ideas. This week we caught up with ChatGPT to find out if there were any new AI books it wanted to recommend in the year since we spoke.
A somewhat obscure text, about 2,000 years old, has been my unlikely teacher and guide for the past many years, and my north star these last several months, as so many of us have felt as if we’ve been drowning in an ocean of sorrow and helplessness. Buried deep within the Mishnah, a Jewish legal compendium from around the third century, is an ancient practice reflecting a deep understanding of the human psyche and spirit: When your heart is broken, when the specter of death visits your family, when you feel lost and alone and inclined to retreat, you show up. You entrust your pain to the community. The text,

I had two memorable experiences with the moon this year. The first was seeing the
