Cancer drugs usually take a scattergun approach. Chemotherapies inevitably hit healthy bystander cells while blasting tumours, sparking a slew of side effects. It is also a big ask for an anticancer drug to find and destroy an entire tumour — some are difficult to reach, or hard to penetrate once located. A long-dreamed-of alternative is to inject a battalion of tiny robots into a person with cancer. These miniature machines could navigate directly to a tumour and smartly deploy a therapeutic payload right where it is needed. “It is very difficult for drugs to penetrate through biological barriers, such as the blood–brain barrier or mucus of the gut, but a microrobot can do that,” says Wei Gao, a medical engineer at the California Institute of Technology in Pasadena.
Among his inspirations is the 1966 film Fantastic Voyage, in which a miniaturized submarine goes on a mission to remove a blood clot in a scientist’s brain, piloted through the bloodstream by a similarly shrunken crew. Although most of the film remains firmly in the realm of science fiction, progress on miniature medical machines in the past ten years has seen experiments move into animals for the first time.

Over the years, I’ve read quite a few books about the brain, most of them written by academic neuroscientists who view it through the lens of sophisticated lab experiments. Recently, I picked up a brain book that’s much more theoretical. It’s called A Thousand Brains: A New Theory of Intelligence, by a tech entrepreneur named Jeff Hawkins.

In 2017, Karen Kostroff, a renowned oncology surgeon at Northwell Health in the New York Metropolitan area added a new talking point to her standard conversation with breast cancer patients facing tumor removal surgery. These conversations are never easy, because a cancer diagnosis is devastating news. But the new topic seemed to give her patients a sense of purpose, a feeling that their medical misfortune had the potential to do something good for other people.

“Private Notebooks: 1914-1916” is a strange and intriguing record — illuminating when it comes to Wittgenstein’s preoccupations, his sexual anguish, his continuous struggles with his “work” in philosophy, along with his intermittent comments about his “job” in the military. (Like other writings by Wittgenstein that have been published posthumously, “Private Notebooks” is a bilingual edition, with German and English printed on facing pages.) Perloff also points out that unlike so many other war diaries, Wittgenstein’s includes very little about the larger stakes of the war itself. One exception is an entry that reads like a startlingly cheerful declaration that his own side was doomed: “The English — the best race in the world — cannot lose! We, however, can lose & will lose, if not this year, then the next!”
