There was considerable interest in nanotechnology in the 1990s without any groundbreaking outcome. More recently interest has increased with the application of nanotechnology to biology. An example is the recent possible breakthrough by Australian researchers in producing a method of using nanotechnology to attack microplastics in the ocean. The large plastic waste mass in the oceans is said to be comprised of up to 94% microplastics. There is considerable concern about this getting into the food chain via seafood etc. We viewed a summary of the paper with subsequent discussion: www.pbs.org/newshour/science/this-new-nanotech-could-help-clean-up-earths-microplastics
Finally we viewed a 25 minute video from Skynews, basically a presentation by Telstra on what’s happening with 5g. Telstra’s website now shows maps of where 5g is being rolled out in the various regions at the present time. Here's the link: www.skynews.com.au/details/_6084409398001
