In Pursuit of Better Baby Formula

Replicating human milk is no easy feat—nor is separating the science from the hype

Unlike classic CRISPR-based editing, which fully cleaves DNA in two, prime editing starts with a cut to only one strand of the double helix.

A New Gene Editing Tool Could Make CRISPR More Precise

Prime editing offers a new way to make changes to DNA while avoiding some of the drawbacks and clunkiness of traditional CRISPR

Soldiers take a psychological test (the exact type of examination is unclear) in Camp Lee in Virginia in November 1917, the year the United States entered World War I and Woodworth first developed his test.

The Future of Mental Health

The First Personality Test Was Developed During World War I

Long before online quizzes and Myers-Briggs, Robert Woodworth’s “Psychoneurotic Inventory” tried to assess recruits' susceptibility to shell shock
