How Burning Plants Signal Future Generations to Grow

Previous studies have reported that chemicals known as karrikins are created as trees and shrubs burn during a forest fire and remain in the soil after the fire, ensuring the forest will regenerate. In the April 23 early online edition of the Proceedings of the National Academy of Sciences (PNAS), scientists at the Salk Institute and the University of California, San Diego, sought to uncover exactly how karrikins stimulate new plant growth.

The researchers found that a plant protein know as KAI2 binds to karrikin in dormant seeds, changing its shape. This karrikin-induced shape change may send a new signal to other proteins in the seeds causing seed germination when the time is right, after a forest fire.

Meet Jeff Wright, a gifted balloon artist and (clearly) a huge fan of the Toy Story series. Jeff created this awesome Buzz Lightyear costume using nothing but an untold number of carefully interwoven balloons.

Click here to watch a brief video of Jeff modeling his suit while impersonating Buzz Lightyear. 

Jeff and his wife Rachel are moving to Bolivia to serve as volunteers at the Life Center Orphanage in the city of Cochabamba, where they’ll no doubt be entertain the children with awesome balloon creations like this. Visit their website to learn more about their charitable efforts.
