Microalgae have been gaining attention as a sustainable, less energy-intensive method for wastewater treatment. This involves growing them in the effluent, where they consume compounds containing nitrogen and phosphorus, as well as heavy metals, pesticides, and particular toxins. Microalgae view these as valuable nutrients, effectively removing pollutants from the water.
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.
Every year, final year PhD candidates present their doctoral studies to the Royal Society of Victoria, competing for four Prizes that recognise excellence in Victoria’s young scientists. Eight finalists present under the four categories: Biological Sciences, Biomedical & Health Sciences, Earth Sciences, and Physical Sciences. While the format of delivery was different this year, participants rose to the challenge to deliver engaging and informative videos for National Science Week. From chicken sexing to neutron stars, all finalists’ presentations are summarised here, with links to their video presentations and the full proceedings as broadcast on the night via Facebook Live.
Our climate is already changing. Under the Paris Agreement, Australia and the world’s great nations have committed to reducing global temperatures to a 1.5-2°C rise over pre-industrial levels. Should this exercise prove successful, a 2°C rise will still have far-reaching climate effects, with major implications for the State of Victoria. This panel of senior scientists were gathered together by the Governor of Victoria to showcase some of the work in climate adaptation produced in our state and, most importantly, share actions we could all take in our personal and professional lives to adapt to the “new normal.”
