Episode 389 - Chronic Pain, Ears, Long lasting Electrodes

Treating chronic pain through tiny electrodes in your ear. Can 3 phase like stimulating of nerves in your eye help treat chronic pain? Mapping out the inside of the ear in incredibly fine detail can help treat chronic pain. Fine tuning tiny electrodes inside the ear can help relieve chronic pain. Using a printer, tattoo paper and polymers to make long lasting electrodes. Flexible, thin and long lasting electrodes can make it easier to study the brain and the heart. Studying the brain over the long term just got easier with tattoo paper based electrodes.

Episode 388 - Cleaning, drinking and shaping water

Making water safe to drink, from evaporation to treatment. How do you simply evaporate water to make it safe? A piece of aluminium and a laser can hold the key to providing cheap and safe drinking water to the world. Pharmaceutical waste can build up in waster water, so how can it be treated? How can two little electrodes deal with the problem of pharmaceutical waste in water? Changing the course of a river can have huge consequences. What can we learn by studying the changes caused by the Panama Canal?

Episode 387 - Black holes dancing, colliding and third wheeling

Scientists have discovered the closet black hole to Earth, but relax it's 1000 Light years away. Ever felt like a third wheel, just be thankful it's not a black hole. A binary star system that can be seen with the naked eye with a lurking black hole. Super massive  black holes are hard to get your head around but can unleash tremendous energy. When two super massive black holes dance around each other, the fireworks are spectacular. Predicting when two black holes will graze past each other helps us refine our understanding of the universe.

Episode 386 - T-rex, Raptors and Giant Squid go a hunting

How fast did T-Rex really go? Was it a sprinter or an endurance runner? Being chased by a T-Rex is scary, but you have to be ready for a marathon not a sprint. T-Rex's long legs helped it be efficient rather than speedy. Did raptors hunt in packs or just near each other? What links Komodo dragons and hunting raptors? Can we figure out if raptors hunted in packs by studying their teeth? Can Komodo dragons help bust Jurrassic Park myths? We also find out about an epic battle between Giant squid and a fish trapped for eternity as fossils.
