So, today’s Aussie fact. I decided to look up medical inventions from Australia. So, I thought, I know that there’s a few medical inventions that were created in Australia. So, I thought I would do a search, I’d list them, I’d mention them, and I would discuss each of them for you, guys. So, I’ve got six here. Okay.
And if you want to read a more in-depth article about these inventions and a couple of other ones that were also listed go to ScienceAlert.com. Okay. It’ll be in the transcript if you want the link to read this article. Okay. Let’s go.
So, number one: Medical application of penicillin. So, the Australian researcher Howard Florey worked with a team in the UK to purify penicillin from a special strain of mould. This is how it was originally done. And he later showed it could fight bacterial infection in humans. The antibiotic changed modern medicine forever, although obviously, we’re going to probably have problems in the near future because antibiotics are less and less effective these days.
Number Two: disease-diagnosing nano-patches. Disease-diagnosing nano-patches. This is still a relatively new invention, but these nano-patches have the potential to change the way we diagnose disease in the future. They were developed by researchers at the University of Queensland, and the patches are covered in tiny microscopic needles that can quickly and painlessly detect disease carrying proteins in the blood. How crazy’s that? And it means that you don’t need a blood test. So, because these patches have access to the human bloodstream, obviously, with those little needles, you don’t have to get blood tests. So, as someone who really hates blood tests, I‘m looking forward to these becoming more predominantly used.
Number three: the bionic ear. I know! I didn’t realise this until I read this too. The bionic ear. One of our best-known exports is the cochlear implant. Both my grandparents have one of these. And the cochlear implant was created by Graeme Clark a researcher at the University of Melbourne. The device has helped more than 250,000 people with profound hearing loss to hear again. So, how crazy is that? The cochlear implant.
Number four: spray-on-skin. Now, I remember this one being in the news. Spray-on-skin has saved the lives of tens of thousands of burn victims around the world and was invented by a woman named Fiona Wood from the University of Western Australia. The invention works by taking a small patch of a patient‘s skin, then growing it in the lab so that it can be sprayed back on to the person’s skin, where they’ve been burnt, over their wounds and create a protective barrier. Really cool!
So, number five: the ultrasound scanner. I didn’t realise this one was ours too. Every expectant mum around the world when they go to the hospital would be more than familiar with the ultrasound scanner, but what people might not know is that the initial discovery that ultrasounds could bounce off soft tissue was made by the CSIRO, and in 1976 it was commercialised by an Australian company called Ausonics.
Number six, the very last one, guys: electronic pacemakers. Another one that blew my mind. The first pacemaker was made impulsively back in 1926, at Sydney’s Crown Street Women’s Hospital to help save a newborn patient suffering from heart problems. The device was used to stimulate the baby’s heartbeat with electric pulses and was created by medical doctor Mark Lidwill, but he was so concerned about the ethical implications of his invention that he refused recognition and patents despite his inventions saving hundreds of thousands of lives around the world.
