Stricter regulation at the state and federal level can reduce the number of illicit vapes available and the associated toxic chemicals inhaled by users. But e-cigarettes still pose a health risk, as nicotine is inherently addictive and increases the risk of serious health conditions. Some single disposable e-cigarettes for sale in Australia contain as much nicotine as 20 packets of cigarettes.
No new antibiotic classes have been invented for decades – the high cost and high risk of failure in blue sky research means new products are variants of existing compounds discovered prior to 1984. So students were invited by Whittlesea Tech School to develop new anti-microbial products to kill harmful bacteria while keeping the good ones safe.
Dr Ross Wissing’s decade working in WaterWatch showed him how to help local communities work with natural resource managers to learn about, understand, and improve the health of their local waterways. Ross fears declining investment means many of the mistakes of the past, and lessons learned, have been forgotten – and are now being repeated.
When Billie Giles-Corti first came to Melbourne, she was challenged by her colleague Dr Ian Butterworth to provide evidence that good urban planning is connected to health in a way that could influence policy. They looked into the social determinants of health: the economic, social and political systems that shape conditions of daily life. They believed that health is linked to access to reliable public transport, health food, local parks, places of leisure, and friends and family.
We spent long periods shrouded in smoke due to the 2019-2020 bushfires that burned upwards of 12 million hectares. In addition to the tragic loss of life and devastation to ecosystems and infrastructure, there were significant levels of smoke exposure across Australia. The lives lost as a direct result are likely to number in the hundreds. Approximately 10 million people experienced elevated concentrations of fine particles on account of the recent fires, exposed to an air quality equivalent to smoking between 20 to 40 cigarettes. These ultrafine particles, less than 2.5 micrometres in diameter (a ninth of a grain of sand), are referred to as PM2.5 particles. Following the 2009 Black Saturday bushfires, the Victorian Bushfires Royal Commission recommended that 5% of public land should be burned annually to reduce the risk of catastrophic bushfires. While protective against large, uncontrollable bushfires, these prescribed burns produce smoke that can have a significant impact on health.
