Episode 325 - Racing against time, from Box Jellyfish to Alzheimers

Medicine is often a race against time, to diagnose, to develop and to treat. This week we're looking at new research which speeds up the detection of Alzheimers in patients and provides a chance to test out potential treatments. We also find out how University of Sydney researchers may help deliver a quick antivenom to those stung by the deadly box jellyfish. Plus ways to turn leftover bits of junk in blood plasma, into useful diagnosis tools that may help save time and lives in treatment without wasting more time on tests.

This week it's stories of scientists and doctors racing against the clock.

There are whole bundles of random RNA fragments in blood plasma, but these can be used to help diagnose specific issues. The box jellyfish is just one of the many things in Australia that is trying to kill you, but now it's slightly less deadly thanks to University of Sydney researchers.
