Alexander von Humboldt has been referred to as ‘the forgotten father of environmentalism.’ As early as 1844, he wrote that humans change the climate ‘by cutting down forests, by changing the distribution of water bodies, and through the production of large vapour and gas masses at the centres of industry.’ Humboldt also described the greenhouse effect in his opus magnum, ‘Kosmos’.
From tiny bacteria to giant blue whales, the chemical reactions going on inside all living things – including us – that keep them alive cannot happen without water. By taking NASA’s lead and following the water, scientists can pinpoint the most compelling locations where life – either past or present – might possibly exist in the vast expanse of the solar system beyond our home planet.
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.
One of the issues with current bionic vision devices is off-target stimulation. The electrical stimulation used to activate cells in the retina tends to spread, leading to inadvertent broad activation and poor visual acuity. As such, developing alternative stimulation methods to deliver greater spatial precision – like optogenetics – are considered invaluable for vision restoration.
Cancer cells have ways to avoid destruction by displaying proteins on their surface that turn off the body’s immune cells, or adopting genetic changes to make them less visible to the immune system, or interfering with how the immune system responds to cancer cells in other ways. Immunotherapy helps the immune system overcome these hurdles to better fight cancer.
