The Washington Post just reported on a new study by Tyrone Hayes, star of THE FROG SCIENTIST. Tyrone exposed some African clawed frogs to atrazine in his lab and produced frogs that are genetically male but lay viable eggs. The transsexual frogs were produced at atrazine levels that are allowed in tap water.

The New York Times reports that the EPA plans to take another look at the health risks of atrazine. Atrazine is the chemical Dr. Tyrone Hayes (subject of my children's book, THE FROG SCIENTIST) has been warning people about for almost a decade, based on his amphibian research. Stay tuned...

Atrazine in the News (Unfortunately)

Tags: atrazine, pesticides, frogs, Tyrone Hayes

A flurry of articles have appeared since the New York Times ran a story entitled "Debating How Much Weed Killer Is Safe in Your Water Glass." A few highlights: the Huffington Post Investigative Fund ran a story, including a video report that includes an interview with Tyrone Hayes. The Center for Biological Diversity then put out a press release with the cheery title "New Research: Herbicide Atrazine Linked to Cancer, Birth Defects, Endocrine Disruption and Endangered Species Impacts." My thanks to Tyrone for these links.

The New York Times just ran a story entitled "Debating How Much Weed Killer Is Safe in Your Water Glass." How glad am I that I filtered my tea water this morning!

Two Stars for THE FROG SCIENTIST

I just found out that THE FROG SCIENTIST received starred reviews from two major review journals (BOOKLIST and THE HORN BOOK). Stars are hard to come by, and in my rather dismal post-Genki mood, these were a wonderful boost.

The Frog Scientist Raps!

Tags: The Frog Scientist, frogs, Tyrone Hayes

Tyrone Hayes, the scientist I profiled in The Frog Scientist, has an Atrazine Rap on YouTube. When was the last time you heard a scientist rap about his research? YouTube also has a video of a more detailed talk by Tyrone: From Silent Spring to Silent Night. Guaranteed, you'll want to buy a Brita water filter after you watch this.
