Science On Top

00:00:52 Michelle Franklin joins us to discuss invasive species control - from giving herpes to carp, to the moth that nearly wiped out the prickly pear. 00:16:57 Scientists have trained archerfish to recognise - and spit at - specific human faces. 00:22:46 A woman in Pennsylvania recently tested positive to an E. coli "superbug" that's resistant to most antibiotics. That's scary enough, but it also points to a worrisome lack of testing and reporting with urinary tract infections.   Michelle Franklin is a wildlife biologist and a founder of the Darwin Skeptics. Phil Kent is an aquaculture specialist and secretary of the Brisbane Skeptics. Brisbane Skeptics have a Skepticamp coming up. Phil can be found on Facebook, Twitter and at the Brisbane Skeptics' Facebook page.   This episode contains traces of Stephen Colbert talking about a new study of frog sex positions.
