A few years ago, molecular biologists Jennifer Doudna and Emmanuelle Charpentier, along with a team of researchers at the University of California, Berkeley, were the first to file a patent for CRISPR-Cas9. It’s a DNA-editing technology adapted from the prokaryote immune system. Cas9 is a protein that can seek out and “cut” targeted gene strands […]

In 1868, on a hot, midsummer day, 28-year-old Mary Lynch was admitted to the Philadelphia Almshouse and Hospital, the city hospital for the poor, better known as “Old Blockley.” Lynch had tuberculosis, which was soon to be compounded by the parasitic infection trichinosis.

On a cold, sunny day this February, artist Brigitte Barthelemy, her husband, and their schnauzer, Elton, went for a walk on a beach in […]

With extravagant swiftness it moves through a cloud, from one cloud to another, or between a cloud and the ground, millions of times every day. The role of lightning in the world’s affairs is much more substantial than its ephemerality might […]

Suicide-bombing ants. Bone-breaking frogs. Spit-flinging arachnids. Back-birthing toads. And bone-dissolving worms. What do all of the above have in common? Specialized adaptations. They’ve become so accustomed to their distinct habitats that they’d be more likely to perish, compared to their more generalist relatives, if moved to a slightly different locale. Each of them, as a […]

To humans, aging can seem to be inextricably linked with physical decline. In 1975, “on a whim,” the photographer Nicholas Nixon decided to illustrate this process. That year he took a picture of his wife and her three sisters standing together, shoulder-to-shoulder; and every year after, for four decades, they stood for a picture in […]
