Jupiter's moons may be way more dynamic than we previously thought. Europa has the most potential to harbor life outside of Earth, but it's ice sheets may be more Earth like than we imagined. Europa's spectacular double ridges are similar to those found in Greenland. The ice sheets on Europa may not be static and still, but churning. Melting and refreezing could drive exchange between the surface of Europa and it's icey depths. How do you form sand dunes without any wind? Is it possible to form a Dune on Io using just volcanic flows and sulfur snows?

Supernova get all the press, but Nova and Micronova are still pretty powerful. White dwarf stars are normally pretty inactive, unless some hydrogen ends up kickstarting them again. Enough helium leeched from a nearby star can ignite the entire surface of a white dwarf. Nova may not destroy the star, but they can create immensely powerful explosions and particles. The right combination of White Dwarf and Red Giant can create powerful particles near the speed of light. Micronova sound small but they are still colossal and brief explosions on white dwarf stars. Not powerful enough to ignite the whole surface of a star, but definitely enough to destroy a planet, micronova are quite deadly.

Using sequencing techniques we can find all kinds of hidden life in our oceans. RNA viruses are ancient, but their old genes can help us spot them in great numbers in our oceans. There are huge amounts of 'life' in our oceans that we don't know about. No matter if you think viruses are 'alive' or not, there are way more than we imagined in our oceans. RNA viruses are easier to spot in our oceans if you look for the right ancient gene. Using gene sequencing we can find fish that are hidden in our reefs. Visually spotting fish is helpful but can overlook sneak fish. Using environemtnal sequencing techniques way more diverse range of fish can be found.

How can bacteria turn methane directly into electricity? Why waste time producing bio gas to burn when bacteria could produce electricity directly. When bacteria take over corn, before they wreck the join they order in delivered food. Bacteria enjoy a huge feast when taking over maize, then they get to work wrecking the joint. Bacteria ends up in spots its not meant to be and redirects food away from plant cells. Redirected takeout food keeps bacteria alive as they settle into their corn host in preparation for taking over. When moving into a new house it helps to get food delivered at first, which is exactly what bacteria does.

Can fish count? What purpose does a stingray have with addition and subtraction? Why are fish and stingrays able to do basic arithmetic without a cerebral cortex? Scientists taught fish to do arithmetic with some help from Bees. What happens with you put a spider web in an anechoic chamber? How do spiders tune their webs to detect sound? Spiders webs act as powerful microphone arrays that are also cable of carrying sound across long distances. Spider webs make powerful microphone arrays that allow spiders to hear great with great fidelity.

Water has some pretty amazing properties. We dive into some of the strange things water does from the molecular level all the way to planet scale water flows. We all know H2O but studying the way water molecules move around each other is very difficult to isolate. H2O molecules had to be taken to 0.4 Kelvin and shot with a powerful laser to shed light on the way they shake. The way H2O interacts between molecules by moving, rotating and shaking can help explain some of the weird properties. H2O has weird properties like being at its highest density at 4 degrees. Turning salt water into fresh water often involves a lot of electricity, but a new method using Ionic salts may get by with barely any heat. How can water make its way down towards the core of the earth? Water masqueraded inside minerals to migrate deep down beneath the surface of the earth.

How can plants defend themselves from attack? Animals scatter when they hear an alarm cry or a predator, but how do plants defend themselves? Plants react to danger around them by detecting chemical signals. Plants emit warning through volatile chemicals and others detect these signals to raise their own defences. How do plants detect light and know where to head without eyes? How do the shape of proteins that bend a plant towards like change when exposed to different light?

Space isn't 'empty' but is often filled with gas and interstellar wind. Gas flows and moves around our universe forming stars, planets and galaxies, but how does it get there? How can you capture the complex motion of interstellar gas? What connects dragonflies with taking pictures of interstellar gas? Strapping a whole bunch of cameras together can help scientists image the faintest of light. Violent eruptions and messy eating by Neutron stars and black holes can help us understand the way interstellar gas moves in space. When a neutron star devours a planet, the remnants and gas flows can tell us a lot about star formation.

Tarantulas are often in horror films, but they too can be subject to a mysterious invasion and slow death by nasty nematodes. "In Hollywood, you haven't really made it until you've been recognized by those in the field of parasitology" says Jeff Daniels. Why did scientists immortalize Jeff Daniels in the name of a deadly nematode. Slowly loosing control of limbs and organs is a nasty way to go out, but its how nematodes can take down a tarantula. Panda's get a lot of help from bacteria to help them survive with their limited diet. Pandas need a lot of help to survive even though they only eat bamboo. Gut bacteria helps pandas turn their bamboo into all the energy they need to build mass and fat.

How can fossils change the planet and the planet change fossils? Forming fossils require specific set of circumstances. How can geological changes make the right conditions for fossils to be preserved? What happened 183 million years ago that made it possible to preserve even soft and delicate fossils? Preserving bones is comparatively easy compared to soft tissue and creatures like squid. So what has to happen to preserve these as fossils? How did fossils change the composition of rocks deep in the mantle? When life first emerged on our planet what change did it cause in the type of rocks found deep beneath the surface? life on the surface has changed the rocks we have deep in the earth.

Ways to protect our cities as climate changes causes more extreme weather. How can we better prepare our infrastructure for damage from extreme storms. Extreme events like storm Eunice can wreck havoc on electricity networks. How can we better prepare our cities? Climate changes makes extreme weather more common so what can be done to predict the risk to key infrastructure? Urban areas can swelter in heat waves, but can urban greening help limit the impact? What benefits does urban greening provide to limit flooding and overheating in extreme weather? When an atmospheric river meets a mountain range it can create a deluge.

Radio telescopes cover large areas and can find strange objects lurking in space. From slowly pulsing magnetars to cosmic ray filaments. Surrounding the black hole at the center of the Milky way are strange but regular filament like structures. Cosmic rays electroncs moving near the speed of light are creating regular 'gash' like filaments around the center of the Milky Way. There is a supermassive blackhole at the center of the Milky Way, but it's surrounded by even weirder things. Astronomers deal with 'transients' from slow ones like supernova to fast pulses like Pulsars...but there might be something in between. A new type of stellar object is pulsing three times an hour dumping out huge amounts of radio waves all relatively close to home.

Giant mouths and giant eyes may look cute, but they give some serious advantages when eating. How do whales manage to gulp so much water to feed without drowning? Lunge feeding where whales swallow huge volumes of water is a fast way to eat but how do whales avoid drowning? Whales and humans share some special developments to stop food (or water) going down the wrong way. Would it be possible for humans to eat underwater like a whale? How do large eyes help a creature? A creature that invests in overly large eyes must have some advantage from them. A cartoony crab with huge eyes was actually a pretty fast predator.

How can we protect skin from frostbite before it happens? Scientists freeze cells in the lab all the time, so how can that be used to help prevent frostbite? When treating frostbite minutes can make a huge difference. How can we improve prevention of the worst injuries from frostbite? You've heard of sunscreen but what about frostbite cream. Antiobiotic resistance is a serious issue, but what plasma could be a secret weapon. Using plasma we can engineer antimicrobial surfaces. Plasma sintered surfaces can wipe out bacteria.

How can we make stronger implants that don't get rejected by the body? Bioactive materials can help make implants feel more at home. Replacing a knee or a hip requires not just strength but also compatibility. A new coating method makes it easier for implants to fit in. An implant has to be strong yet flexible, friendly to cells but not bacteria - it's challenging. Your vocal chords are subject to extreme forces, so how can we design an implant to repair them? Hydro-gels can help repair damaged organs and tissue even in extreme environments like your vocal chods.

When Tsunami's strike, every extra minute of notice can help save lives. How can scientists better predict the height and journey of a tsunami? We look at the ways scientists can use tectonic plates or magnetic fields to improve tsunami predictions. Where an earthquake occurs can make a big difference to the size of a tsunami. The shallower an earthquake in a thinner sub-ducting plate can lead to higher tsunamis. When you move a large amount of sea-water the earths magnetic field changes, just enough to detect. Like reading the vibrations in seismic waves, earth's magnetic field changes enough for you to identify a tsunami. Using magnetic fields you can measure and asses the height of a tsunami much faster.

From Hedgehogs to mouthwash, we check in on the arms race against bacteria. MRSA super-bugs are a super problem for humans, but some pre-date the modern era. MRSA super-bugs have been around since the Industrial revolution, at least on hedgehogs. The skin of hedgehogs is a battlefield between Fungus and Bacteria, and whoever wins, we loose. We often focus on Humans vs Bacteria, but it's actually a triple threat with Fungus. The fight Fungus vs Bacteria can lead to the development of antibiotic resistance. The mouth is the gate in the castle like defenses of the human immune system, so what defends it from bacteria attackers?

Rogue planets hurtling across space without a place to call home. How do we detect intergalactic nomads like Rogue planets? Just how many rogue planets are out there? Are there rogue planets lurking in our own solar system? Glass inside meteorites can help us understand early earth. How does meteorite rock differ from rock here on earth? What can we piece together about the cataclysmic events that formed glass inside meteorites? Rapidly heating then even more rapidly cooling coalesced glass inside meteorites.
