NYBG Scientists Help Discover a Promising Anticancer Agent to Fight a Childhood Scourge

Posted in Interesting Plant Stories on March 30, 2016 by Daniel Atha

Daniel Atha is the Conservation Program Manager at The New York Botanical Garden.


A chemical agent found in a member of the snapdragon family (Scrophulariaceae) has shown early promise as a potential treatment for a cancer whose victims are overwhelmingly infants and children.

I recently co-authored a paper describing the potency of a chemical extracted from Armenian figwort (Scrophularia orientalis) in killing malignant cells found in neuroblastoma, a cancer of the nervous system. Neuroblastoma is the most common non-brain solid tumor in children and the most common cancer in infancy (NIH NCI, 2016). Almost half of its victims are children under two years of age.

Edison and Rubber: A Scientific Quest, a new permanent exhibit at the Edison and Ford Winter Estates in Fort Myers, Florida, is a multi-faceted exploration of inventor Thomas Edison’s major final research project on domestic rubber. Both the exhibit and the 20-plus-acre site present a fascinating blend of history, science, botany, and innovation. The New York Botanical Garden, which is historically connected to the Estates through Edison’s rubber research, has gladly joined this interactive exhibit with a display of recently discovered herbarium materials.

Living Fossils: A Scientist’s Fascination with Cycads

Posted in Interesting Plant Stories on March 9, 2016 by Stevenson Swanson

Stevenson Swanson is the Science Media Manager at The New York Botanical Garden.


Palms of the World Gallery cycadCycads, an ancient group of cone-producing tropical plants, are sometimes called “living fossils” because they have existed for more than 200 million years–since before the time of the dinosaurs. Yet despite surviving mass extinctions, continental drift, ice ages, and other challenges, cycads are in trouble today.

Some cycads such as the sago palm are popular commerical plants, but in the wild, habitat destruction and poaching are now pushing many species in this group to the brink. The International Union for the Conservation of Nature has said that 53 percent of the approximately 300 species of cycads are imperiled.

One of the world’s leading experts on this intriguing group of plants is Dennis Wm. Stevenson, Ph.D., Vice President for Botanical Research and Cullman Curator at The New York Botanical Garden. Dr. Stevenson’s cycad research has taken him to every continent, including Antarctica, and he has discovered and described many new species.

Recently, Matt Candeias of the blog and podcast “In Defense of Plants” talked to Dr. Stevenson about his decades-long fascination with cycads, which began during his years as a graduate student at the University of California-Davis. You can hear their conversation here.
