Episode 391 - Mysteries of the sun, stellar weather and magnetic fields

The sun contains many mysteries, which are hard to unravel without special space probes. Why is the sun's corona so much hotter than the sun's surface? What helps form the biggest solar flares? When two arches of the sun's magnetic fields meet it can create some dangerous flares. Solar storms and solar flares can destroy satellites, power grids and spaceships. How can we better predict stellar weather and avoid disaster? Mapping out the Suns magnetic field can help us better predict stellar weather.

Episode 390 - Cool fabrics, melting ice and recycling e-waste

From cool fabrics, to melting ice and recycling e-waste. How can a fabric let air through, but keep water out? Clothing that is breathable, water resistant and thermally efficient hits the sweet spot of a super fabric. Making clothes more efficient at cooling but also self cleaning can reduce our reliance on air conditioning. Using electricity and some polymers we can spin up some new cool clothing fabrics. Melting ice in your frozen over freezer can be made easier with biphillic materials. Materials that both hate and love water at the same time, can help melt ice and make heater exchangers more efficient. Recycling e-waste can be tricky, but what if we could use the by-products to  make new, stronger coatings for steel? Turning e-waste into a steel boosting coating.

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.

Episode 385 - Understanding what makes water stick together

What seems simple but it's deceptively complex. What makes water molecules stick together, or ice to float on top? Water has many mysteries, like ice floating on liquid. The key lies in the energy distribution. Shooting super high frequency lasers at water can help figure out what makes ice float or water stick together. Cheap and efficient ways to clean water is essential for saving lives across the globe. How can cyrstaline sponges help soak up bad chemicals like hexavalent chromium.

Episode 384 - Plants regenerating and fighting off invaders

How do plants manage to recover from damage or fungal attacks? What happens when you shoot a laser at some cress? Studying the way plants respond to damage helps us understand their regeneration methods. Plant cells can regenerate to recover from damage, but what controls this process? Fighting off a fungal invasion means an arms race between plants and fungus. Plants like cabbage use a special mustard oil bomb to fight back against fungal invaders. Fungal invaders like white mold can render even the most sophisticate plant defences useless.

Episode 377 - Hubble turns 30 and still takes amazing images

We celebrate the life and achievements of Hubble Space telescope and all that have worked on it over it's 30 years in space (and many more before that). We look at the challenges faced by Hubble early on, and the amazing science it is helping contribute to today. From stars being born, to comets tearing themselves apart Hubble sheds light on amazing science. The images Hubble takes are iconic and often look like science fiction. Hubble manages to celebrate it's birthday by capturing images of a comet tearing itself apart.
