At almost every frontier in theoretical physics, scientists are struggling to explain what we observe. We don’t know what composes dark matter; we don’t know what’s responsible for dark energy; we don’t know how matter won out over antimatter in the early stages of the Universe. But the strong CP problem is different: it’s a puzzle not because of something we observe, but because of the observed absence of something that’s so thoroughly expected.

Why, in the strong interactions, do particles that decay match exactly the decays of antiparticles in a mirror-image configuration? Why does the neutron not have an electric dipole moment? Many alternative solutions to a new symmetry, such as one of the quarks being massless, are now ruled out. Does nature just exist this way, in defiance of our expectations?

Through the right developments in theoretical and experimental physics, and with a little help from nature, we just might find out.

Lawyers and doctors are typically paid more than manual laborers because of the relative shorter supply of lawyers and doctors, which is in part due to the number of years of training required to enter those professions and the corresponding value society attributes to those skills. But what will happen to their wages once the market is faced with an abundance of skilled labor? If anyone is able to upload legal or medical know-how to their brain and know just as much as the professionals in those fields, why pay a professional a higher wage?

Of course, certain skills, such as strategic judgment and contextual understanding, may be difficult, if not impossible, to digitize. But even the games of chess and Go, both complex games that require strategic decision-making and foresight, have now been conquered by AIs that taught themselves how to play—and beat—some of the best human players.

The technology’s potential for emancipation and human advancement is immense. But we—entrepreneurs, researchers, professionals, policymakers, and industry—must not lose sight of the social risks.

Regrowing bones is no easy task, but the world’s lightest solid might make it easier to achieve. Researchers have figured out a way to use hybrid aerogels, strong but ultralight materials, to prompt new bone tissue to grow and replace lost or damaged tissue.

Although bone cancer is a relatively rare disease (it accounts for less than 1% of all cancers), people who suffer from it often end up losing a lot of bone tissue and, in extreme cases, undergo amputation. The cancerous tissue has to be cut out, taking with it a large chunk of nearby healthy tissue to make sure that the cancer does not spread. This effectively removes the cancer, but also leaves the patient with a lot less bone than they started out with.

William Li presents a new way to think about treating cancer and other diseases: anti-angiogenesis, preventing the growth of blood vessels that feed a tumor. The crucial first (and best) step: Eating cancer-fighting foods that cut off the supply lines and beat cancer at its own game.
