Temporary vasectomies could be a "game-changer" for contraception if a world-first trial at a Melbourne hospital is successful.Twenty-five men taking part in the study will have a hydrogel injected into the vas deferens — the tubes that carry sperm — to stop sperm travelling from the testicles.It's believed the effect of the hydrogel would last for about two years and could then be reinjected, offering an alternative to a standard vasectomy, which is intended to be permanent.https://www.sbs.com.au/news/article/in-a-world-first-an-australian-hospital-trials-game-changing-temporary-vasectomies/69zs897b6?
With populations growing and temperatures rising, shifting to a more sustainable future in agriculture is essential.The model potato farm feels a little like Star Trek: an international, multicultural crew armed with laptops, sensors and drones boldly going where no potato farmer has gone before.A team of postgrads from Dalhousie University, for example, is working on a crop-spraying rig that uses artificial intelligence to identify bugs and weeds that can harm the crop. Instead of spraying the whole field, pattern-recognition systems spot unwanted invaders and direct nozzles to target them. It takes just 200 milliseconds to identify a beetle and spray it.https://inkl.com/a/AmywxatAXN
