From pulsars to fast radio bursts, we look at interstellar mysteries. Just how do Pulsars work? How long does it take for a Pulsar to be fed by surrounding matter? All that accretion disk matter spillaring around a Pulsar takes a long time to get there. What are Fast Radio Bursts? mysterious signals from deep space, or wobbly highly magnetised neutron stars? Magnetars, fast radio bursts and flares. What causes a fast radio burst in space to repeat?

New comets, touching down on an asteroid and fake diamonds on the moon. Small objects in our solar system can teach us about the early days of Earth. What happened on the moon 4.5 billion years ago to form cubic zirconia on the surface? What can we learn about the moon 4. billion years ago in dust brought back by Apollo 17? A new comet is appears for the end of May which you can see near sunrise. Another comet discovered by Michael Mattiazzo can be see near sunrise at the end of May. Touching down on an asteroid is an incredible feat, and the preliminary data from Hyabusa2 and Ryugu are fascinating.

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.

Taking the fight to bacteria with lasers, metal and insect wings. How can lasers help make a material into a bacteria destroyer? Metal in fantasy has demon slaying properties, but how can it help fight bacteria? What can we learn from insect wings to help make safer implants? What is it about silver that makes it good for killing bacteria (and werewolves). Why are metals so dangerous for bacteria? How can we treat and use metal to make medical devices safer from bacteria?

Satellites can help save lives down on earth, by helping us better respond in disasters. When a flood, tsunami or other disaster strikes, satellites can help emergency responders get where they need to be as fast as possible. Satellites can track floods in near real time and help shave minutes of disaster response times. Finding your way in a flood or fire can be tricky, but satellites can help direct emergency responders. Satellites can help track critical infrastructure like bridges or roads as they age. When a bridge fails it can be a tragedy, but satellites can help give an early warning. When we dig big tunnels we can disturb structures and buildings, so how can we use satellites to avoid a disaster.

Smart phones, computers, televisions and even children's toys are part of what makes our modern world so exciting. But these often rely on plastics and rare earth metals which are hard to recycle. Are there efficient ways to capture all those rare earth metals? How are rare earth metals in old phones recycled today, and can we make it better? Knowing which bin to put plastic in is difficult, so what if there was a more universal way to recycle plastics? How does turning plastic into a gas with the help of steam help create a circular plastic economy? How can some steam power help crack plastics back into their most basic forms? Is it possible to recycle plastics without to build whole new plastic refineries? Regulation is often playing catch up to making materials safe. Are the latest generation of 'safe' fire retardants any safer than those that came before?

Boiling planets being stretched and squished. Tiny white dwarf stars going supernova. Goldilocks planets potentially with liquid water. Exoplanet hunting is now a lot easier with missions like TESS and veterans like Hubble. We look at some special cases, and how searching for 1 planet can uncover loads more. Sometimes planets are lurking in old observatory data, we just need to know where to look. Too hot, too cold, GJ357 potentially has a planet that's just right with liquid water. What causes a White Dwarf to go supernova? It needs more than itself to kickstart it into a Type 1a nova...so where does the extra boost come from? Devouring another planet? Or another star?

Getting a prosthetic limb to feel natural and comfortable without spending a fortune is incredibly difficult. Plus the human body (and prosthetics) change over time. So how can you make a prosthetic better match it's user? We look at three stories of adaptive prosthetics and finding ways to make use of new technology to help improve lives. From building an elaborate treadmill contraption to hearing through your fingers.
When you stumble your brain goes into overdrive to keep you standing, but what exactly does it do?
Affordable and comfortably fitting prosthetic limbs are especially important for children who grow out of them quickly. How can we make them more responsive?
Hearing words clearly in a noisy environment is especially hard on those with hearing aids. But can your fingers help out?
Vanderbilt University researchers built an elaborate treadmill to trip people, with the goal of helping advance prosthetic research.
Using 3D scanning, printing and embedded sensors, researchers are making prosthetic better matched to their users.
People often say look with your eyes not your fingers, but can you use your fingers to hear as well?
Embedding sensors into 3D printed prosthetics can help adapt the design to better suit the actual wear and tear from the body.
Using an elaborate tripping contraption on a treadmill, Vanderbilt university researchers hope to stop prosthetic leg users falling over.

Our modern world relies on energy, and some of it produce a lot of carbon dioxide. How can we make everything from air travel to wearable tech be less carbon intensive? Is there a way to make jet fuel or power ships that is carbon neutral? Just how much energy do crypto currency burn up? What is the impact of all this Bitcoin speculation on the health of the planet? From Fitbits to smart watches and Pokemon Go, wearable tech is a big trend, but how can we make these devices power themselves. There is a lot of excess energy when we walk and move, so can we use this to power our technology?

Mathematics is not just something humans can perform. It's present across the universe and especially in nature. So can animals understand abstract mathematical concepts? Can we learn from the different complicated algorithms and mathematical models used by animals to improve the internet of things? What can social media help tell us about both human and animal tourists to nature reserves?
