| The Science Show | Stanford University scientists sampled nearly 1400 climate change deniers and found a pronounced disparity in expertise between the climate change deniers and the scientists. The Science Show | As carbon dioxide increases in the atmosphere, plants become more efficient at producing their food and chemical requirements and allocate more resources for pest defence. This is good for the plants, but bad for the animals that eat them. The Science Show | Genomic information from about 200 species of plants has allowed the tree of life to be drawn, showing the relationships between all plants. Ockham's Razor | Today's excessive demand for electricity comes from appliances that clutter the average Australian household. Dr Trevor McAllister discusses our dependence on electricity, which began with the incandescent light bulb. The Health Report | Frailty is a huge health problem for older people. What is frailty? Is it inevitable? And can it be reversed? Researchers have investigated the effect of oral vitamin D in older women who have experienced falls or fractures and found that how you take it just might make a difference. RN Breakfast | Scientists in West Africa have potentially uncovered the oldest fossilised multi-celled life on Earth. The fossil remains are thought to be billions of years old. RN Breakfast | A group of Australian researchers is at the forefront of bike design and technology, aiming to make a lighter, stiffer, and ultimately smarter bike. Bush Telegraph | Scientists claim that BT cotton has led to a 90 per cent reduction in pesticide use. The gene produces a pesticide which has been used for 50 years as a spray and can even be used on organic crops.
Catalyst | Is there such a thing as the male pregnancy? Dr Jonica Newby follows three dads-to-be, testing their hormones and their humour as they make the transition to fatherhood.
Innovations | For the first time, six radio telescopes have been linked together to act as one giant telescope. It's a five-and-a-half-thousand kilometre connection extending from Australia's west coast to New Zealand. The link-up demonstrates the possibilities of an Australian-hosted International Square Kilometre Array Telescope, which when built will combine more than 3000 antennae.
