There is a webinar for interested entrants Nov. 16 (Wed) http://www.aldakavlilearningcenter.org/learn/flame-challenge-scientist-information-session
Eligibility:
“The contest is open only to scientists. For this contest, we define a scientist as someone who has, or is in the process of getting, a graduate degree in a science (including health sciences, engineering and mathematics), who is employed doing scientific work or research, or who is retired from doing scientific work.”
Alda has of late been a champion of science communication, and his web site has good resources for improving your outreach: http://www.aldakavlilearningcenter.org/
