In the first episode of SciTech in a Flash, we dive into the world of creepy, crawly, cockroaches. The pesky cockroaches we sometimes find in kitchens, sewers and basements make up less than one percent of all cockroach species. Researchers estimate there are as many as 20,000 roach species on the planet and less than 5,000 have been catalogued. Our partners at Science Friday bring us inside a cockroach research lab, working to identify different species, at Rutgers University in New Jersey.SciTech Now airs weekly on public television stations nationwide (check local listings).For more for more stories like this visit scitechnow.orgLike us on Facebook: facebook.com/scitechnowFollow us on Twitter: @SciTechNowJoin the conversation with #SciTechNow
