Summary The latest in electric cars; cancer test kits saving lives; come on a tour of the alimentary canal!; why can't we walk in a straight line?; and upside down jellyfish.BEYOND PETROLDemand for oil is starting to outstrip supplies and unless alternatives can be found, oil supply could soon fail to meet our needs. One way to offset demand is by switching from our beloved gas guzzling automobiles to electric cars. Governments are encouraging development and car manufacturers are taking different approaches to the challenges of batteries, and how to balance achievable range against available power. Jonica Newby travels to the US motor city, Detroit, and gets behind the wheels of the front running electric cars of today and tomorrow. BOWEL CANCERAround 80 Australians die each week from bowel cancer. Fortunately, it can be treated successfully if detected in its early stages, but currently less than 40 per cent of bowel cancers are detected early. A test kit distributed as part of a national screening program has helped improve early detection rates, but will the program be continued? Dr Maryanne Demasi reports on the present threat to end the program and the call from doctors and the Cancer Council to not only continue the program but to expand it. TOURING DOWN UNDERWelcome aboard this elementary tour of the alimentary canal. As you peer out the windows of our viewing pod, observe the abundant native flora and how the nutrients and water are absorbed through the walls of the small intestine and colon. JELLYFISH VORTEXThe upside down jelly fish Cassiopea, spends most of its time with its 'legs' in the air and the 'top' of its bell resting on the seafloor. Researchers from the University of North Carolina injected dye into the sand below the jellyfish and demonstrated how the bell's pulse creates eddies that bring nutrients to the frilly feeding arms. WALKING STRAIGHTIt's true that people who get lost in the desert without a compass can end up walking around in circles - but why? Graham Phillips and Ruben Meerman get together to demonstrate the phenomenon and try to solve the puzzle
