Australian sea floor expands Australia is 2.5 million square-kilometres larger following the United Nations recognising Australia´s claim to more of the sea floor around the continent. Australia doesn´t own the fish in the water, but it is responsible for the sea floor. Some trenches go to a depth of 10 kilometres below the surface. Tim O´Hara describes some of the animals which live at these depths. The Loh down on science - Scent of a stripper Sandra Tsing Loh discusses pheromones, how they change during the menstrual cycle, and how they are effected by the pill. QED - a play about Richard Feynman Henri Szeps plays Richard Feynman in Peter Parnell´s play about physicist Richard Feynman. Henri Szeps discusses his character and we hear some archival material of Feynman. Flacco - Dark matter Unicellular organisms in Antarctica - response to extended darkness and temperature change Andrew McMinn describes the challenges of 24 hours of darkness, and 24 hours of daylight, and the amazing transmission that takes place over about 6 weeks. The Lewin physics lectures Walter Lewin has been teaching physics at MIT since 1972. He employs large doses of fun with large-scale demonstrations in his classes. These include charging himself using a Vandergraph generator, and swinging from the end of a giant pendulum. He also employs practical jokes and puzzles. As well as mention in The New York Times 100 of Walter Lewin´s lectures can be found online. Mentoring for science students Mentoring was mentioned in the recent National 2020 Summit as a new idea. But the idea is in operation already, with much success in Israel, and for the last 15 years at Perth´s Murdoch University. Russell Elsegood argues the idea should be adopted nationally.
