It’s clear a child’s early experiences can leave a lasting imprint on how their brain forms and functions.

But for all the technology’s potential for automating tasks, a growing body of evidence also shows that AI can be prone to bias that disadvantages already vulnerable patients.

Some 30,000 years ago over the volcanic plains just southeast of what is today Rome, the soaring flight of a griffon vulture (Gyps fulvus) ended in scorching catastrophe as a wave of volcanic ash and debris immolated and buried the bird. In 1889, a landowner found the creature’s fossilized remains. Soft tissues—especially feathers—usually decay quickly and rarely leave behind impressions in rocks. And only fossil feathers trapped in amber have been shown to maintain their 3D structure.
