About Lydia

I am a science journalist who investigates everything from Alzheimer’s to zebrafish. How do we think, learn, and connect? How do we stay healthy—mentally and physically? What’s really going on in the brains of toddlers and teenagers? And what can we learn about ourselves from the behavior of other animals?  I explore the cutting-edge science behind these kinds of questions in my books and articles. I am a contributing editor for Scientific American where I write the Science of Health column, and have contributed to many other publications. My work is supported by the Alfred P. Sloan Foundation.

Praise for Lydia's Books

Toxic Truth . . . make[s] the process of scientific research riveting . . . The problem [of lead] has not been totally solved, but it has been shrunken and contained, and Denworth’s fascinating historical, biographical, scientific and political saga shows how we got even this far.”

—Sharon Begley, Newsweek

I Can Hear You Whisper is a triptych of reportage, popular science, and memoir. As reportage . . . it’s both timely and rigorous . . . As popular science, it’s enthralling . . . As a memoir it is tender and involving.”

The New York Review of Books

“The power of friendship—in many ways the most essential of our relationships—has long been underestimated. It's an absolute pleasure to see Lydia Denworth do it justice in this lovely, insightful, and important book.”

—Deborah Blum, Pulitzer-prize winning author of The Poison Squad (on Friendship)
