Episode 372 - Flexible and wearable electronics

How can we make flexible electronics for our clothing? What does it take to make a screen that's flexible without relying on plastics? What aquatic by product can help make biodegradable, flexible electronics? Why do your towels go hard when you dry them in the sun? What happens on cotton fibres to make them stiffen up in the sun? How does fabric softener work - we're really not sure.

Episode 371 - Marine Mammals vs Parasites

Its a battle between Marine Mammals and Parasites. How does an opossum parasite start killing sea otters?  In #2020MMM unexpected combatants can ruin your day, just like how opossum parasites are taking out sea otters. How does a parasite make a long journey from land to end up out at sea? Inside raw fish, parasitic worm populations are booming. This is bad news for marine mammals. Conserving marine mammals can be a delicate balancing act as parasite populations can also start to thrive.

Episode 370 - Explosions in space and citizen science

From galactic explosions, and waiting for supernova space is full of mysteries. What happens when a super massive black hole in a massive galaxy cluster...erupts? A massive explosion shred a hole 15 times larger than the Milky Way. What is happening with Betelgeuse? Could Betelgeuse just have shed it's coat? Is Betelgeuse about to go 'nova or is something else happening?   We find out about galactic research you can do from your couch. Tracing out a spiral is easy for humans to do, so why not help trace out a galaxy? Looking for something to do at home, why not citizen science helping trace galaxies?

Episode 369 - 2020MMM, Endangered species and City Foxes

Conservation, Adaptation and March mammal madness, an animal special. What is the difference between an urban and a country fox? Why is an city fox bolder than a country fox? How many eels can you fit in a kilogram bucket? How do critically endangered eels end up on the supermarket shelves? How do you smuggle vast quantities of eel across borders?

Episode 368 - Brain injuries, epilepsy and treatment options

How can we give better quality of life for those suffering from neurological conditions? Getting a concussion is bad enough, but why do people often develop epilepsy afterwards? What is the link between concussions and epilepsy? How can we effectively reduce the risk of epilepsy after a concussion? For certain epilepsy conditions in children, CBD can help reduce seizure risk, but what type is best? Is pharmaceutical or artisan CBD for children with epilepsy?
