  • SoT Special - Friends of Science in Medicine

    In early 2012, the lobby group Friends of Science in Medicine wrote to the vice-chancellors of Australia's universities asking them not to allow the establishment of unscientific alternative medicine courses. Established only five months ago, Friends of Science in Medicine now boasts more than 500 members. They are currently campaigning "to reverse the current trend which sees government-funded tertiary institutions offering courses in the health care sciences that are not underpinned by  sound scientific evidence".

    Shayne and I caught up with Dr. Rob Morrison, a co-founder and Vice President of Friends of Science in Medicine. Rob has won two Eureka Prizes, was Senior Australian of the Year for South Australia in 2008 and is a Professorial Fellow at Flinders University. Also he co-hosted The Curiosity Show for 18 years.

  • SoT Special - ASC2012

    The Australian Science Communicators National Conference was held at the Sydney Masonic Centre from 27 to 29 February. Opened with an address from Australia's Chief Scientist, Professor Ian Chubb, the conference was three days filled with inspiring stories, intriguing ideas and vigorous discussion.

    After the conference I caught up with Kylie Sturgess, Dr. Krystal Evans and Sarah Keenihan to get their thoughts.
