Our environment cannot bounce back from major petrochemical contamination, on top of the constant flow of waste from agriculture, textile factories and our homes. The cheap and easy approach to dealing with waste has been to simply bury it, which is unsustainable, especially as chemicals inevitably leech out into soils and waters. While thermal desorption removes contaminants, it also kills the soil. The best solution is bioremediation.

With deep expertise in environmental microbiology and biotechnology, Professor Andrew Ball’s research focuses on developing clean, sustainable technologies to remediate environmental contamination, looking for ways of removing contaminants – particularly petroleum hydro-carbons (oil), but also other organic pollutants – from soils, groundwater and water bodies.
Let’s Torque is a Science, Technology, Engineering, Mathematics and Medicine (STEMM) communication skills development initiative that runs a public speaking competition for undergraduate students. In 2017, a group of students in Monash University’s Global Challenges course (BSc Honours) launched a dynamic program that is now run by and for students from all universities across the state. Our thanks to all participants for stepping up for this year’s locked-down competition!
Human activities have released significant quantities of carbon dioxide into the atmosphere. As a greenhouse gas, the more carbon dioxide emitted, the warmer our planet becomes. Partly mitigating these impacts, plants recover 30% of atmospheric carbon via photosynthesis. Using energy from the Sun, they combine carbon dioxide with water to form sugar and oxygen. When the chemical reaction is reversed, carbon returns to the atmosphere – either by cellular respiration in plants and animals, or the burning of coal, wood, or gasoline. Soil scientist Dr Samantha Grover explains that one way of preventing carbon dioxide from returning to the atmosphere is keeping it sequestered in the ground. In fact, there is two-to-three times more carbon in soil than in the atmosphere.
Everyone’s reality is slightly different. We all experience the world around us in different ways. Our world is sensed as numbers and electrical impulses that our brains then turn into something meaningful. At Extrasensory, everyone was challenged to make sense of the world of the senses and find the limits to their own. There were many incredible sights, tastes and sensations to behold while exploring the magnificent spaces of the Parliament of Victoria!
