In Situ Science returned to the Django Bar to celebrate National Science Week and the Sydney Science Festival. This year we we’re joined by Cameron Webb (USyd and NSW Health), Katherina Petrou (UTS), Fonti Kar (UNSW) and Samuel Bannister (USyd) who shared stories about everything from studying marine algae in Antarctic sea ice to fishing for komodo dragons with giant genetically engineered mosquitos. https://mcdn.podbean.com/mf/web/r4vy6z/Life_Vs_Science_2019.mp3 We … Continue reading Ep 83. Life Vs Science 2019
A single tweet can make all the difference, or at least it did for Andrew Katsis, who decided to get involved in the #billmeetsciencetwitter trend. Little did he know that his tweet would be seen by American television producers, who decided to fly Andrew over to LA to talk about this research on the Netflix show ‘Bill Nye Saves the World’. Andrew’s research looks at … Continue reading Ep 82. Emu farming, pregnancy tips and Bill Nye the Science Guy with Andrew Katsis
Amy Martin is a researcher at the University of Auckland that studies the incredible private lives of orchids that trick male wasps into mating with them. By depriving these wasp populations of male sperm they can actually have long term effects on the wasp populations. Amy says that this is why deceptive orchids the world over tend to use haplodiploid insects as their pollinators as … Continue reading Ep 80. Deception, maths and parental expectations with Amy Martin
This episode sees our first ever geologist on the podcast. Tim Chapman is a postdoctoral research fellow at the University of New England. He studies the high energy geological reactions, such as the formation of volcanoes and meteorite impacts, and what influence these have had on our landscape. https://mcdn.podbean.com/mf/web/tudehb/TimChapman.mp3 As we discuss the cutting edge of geological science, Tim answers such pressing questions as ‘what … Continue reading Ep 79. Meteorites, volcanoes and Armageddon with Tim Chapman
John Paterson is a professor of paleontology and earth sciences at the University of New England. He studies the evolution of life during the Cambrian explosion. Some of his recent research has shown that during this time some of the largest predators around, Anomalocaris, had wonderfully complex eyes and they were likely to be incredible visual predators of their time. In this interview we also … Continue reading Ep 77. Craft beers, trilobites and Lagerstätten with John Paterson
Wetlands, despite their name, aren’t always wet. But when the rain starts and the rivers flow theses dynamic landscapes can flourish with life. Though the question remains, how much water is enough? Freshwater ecosystems have been significantly altered by water management for human use. In particular, flow regulation has resulted in enormous declines in both the extent and health of wetlands. In 2018 Lindsey Frost … Continue reading How much water does it take to grow a duck?
The global demand for poultry continues to rise but the resources we have to produce them don’t, so how can we continue to farm poultry sustainably, ethically and responsibly? A large proportion (20%) of dietary protein fed to broiler chickens is undigestible. These represent a significant proportion of diet cost and may have negative effects on broiler gastrointestinal health and performance. Moreover, decreasing protein excretion … Continue reading The Science Behind Poultry Farming
