McMurdo Station is the American staging area for Antarctic research. At the edge of Ross Island, off the coast of the continent, a small town of workers feed, house, prepare, supply, fuel, transport, and protect those who conduct field research throughout Antarctica and the surrounding waters. The community numbers 1,000 in the summer and 200 in the winter.
And the community has a garden. In these conditions Watch as Exploratorium staff and local teachers compete for the title of Iron Sscience Teacher. Each contestant has ten minutes to make a science lesson out of a secret ingredient. Today's ingredient is related to our Women's Health Exhibition-feminine hygiene products! What does it mean to find the Higgs Boson at CERN? Hear how this elusive particle could change our understanding of physics. The Exploratorium's Senior Scientist Tom Humphrey takes you around the Antiproton Decelerator, from beam pipes to antihydrogen traps. Follow CERN's Mission Impossible team as they race against the clock to collect all they need to bring antihydrogen back to CERN's webcast headquarters. Scientists at CERN in Switzerland explain to the Exploratorium's San Francisco audience why preparing for antimatter experiments is like arranging a marriage. Making antihydrogen is no easy matter. Researchers at CERN show the Exploratorium's Melissa Alexander and Tom Humphrey where positrons live and how they keep them as cold as deep space.
