Episode 406 - Lifting mountains out of the ground…with rain

Lifting mountains out of the ground with...rain? How do mountain ranges form is a surprisingly difficult question to answer. Complex equations with lots of inputs are tricky to model and solve, but can help us understand the way mountains form. Rain, cosmic particles, sand and the Himalayas can help us understand how mountains form. It's hard to picture, but mountains actually float on the molten rock of the mantle. Make them lighter and they'll rise. Do rapid climate swings change mountains, or do mountains change the climate? The answer is tricky.

Episode 400 - Nobel Prizes, Collaboration, and more sustainable trees

The Nobel Prize's legacy on gender and diversity is poor, but are they turning it around? We celebrate the winners of the Nobel Prize, but look critically at the challenges of the system. How do you recognize the collaboration of 100s or 1000s of people with a single award? Is science advanced through singular genius or the collaboration of many? How can CRISPR help us create a more sustainable planet? Growing trees that are easier to process but still able to thrive is possible with CRISPR. How can making trees with less lignin help make a greener planet?

Episode 395 - Learning from unusual plants

Plants are incredibly important for a healthy planet and a well fed population. How can we improve our plants by learning from some unusual ones? You normally picture a plant with lots of leaves, but some only grow one lonely leaf. Deep in limestone caves of South East Asia grows a plant with only ever one giant leaf. How can a plant survive with just one leaf and why does it continue to grow in size? What can we learn by studying the root systems of different plants? Can breeding plants to have more flexible roots lead to more resilient crops?

Episode 373 - Deep sea reefs, ocean vents and tiny life

This week we look at unlikely partnerships that help sea creatures survive and thrive. What plays a crucial role inside a reef's ecosystem that is often overlooked? What's inside fish guts that help keep a reef healthy? Just how do fish 1000s of kms away end up with the same colonies of microbes? Feel like a tasty snack but stuck in the deep ocean vents, why not methane? How do microbes help worms eat methane?

Episode 362 - Life after a disaster from Fukashima to Chernobyl

What happens next after disaster strikes and people flee for safety? How do wildlife move in when people move out of a disaster zone? How do animals moving into an evacuated area change with no humans around? What is the most effective thing to do if you live near a disaster area? How do we assess risk and life expectancy impact of living near a disaster zone? Is it more dangerous to live near a nuclear plant or in the diesel smog of the big city?

Episode 358 - Wildfires, climate change, smog and charcoal

As the climate changes, wildfires become more common and more dangerous. Smoke clouds from wildfires can linger for weeks, but what chemistry changes inside the smog? Aerosols amongst other particles lurk inside wildfire smoke. How do we study the changes in wildfire smoke; by flying planes through the plumes. How do wildfires impact the CO2 emissions of a region?  Can wildfires help store carbon through charcoal? What can charred biomass to do help capture carbon?

Episode 355 - Satellites keeping us safe on the ground

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.

Episode 350 - Developing, tracking, recycling new materials

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?

Episode 347 - Capturing carbon with better farms and forests

Capturing carbon is important for helping offset CO2 emissions and tackling climate changes. Farming has an important role to play in improving CO2 sequestration with the use of cover crops and compost. Forests are important carbon sinks too, but they are at risk releasing a lot of the trapped carbon if care is not taken to stop invasive species. Plus fertilisers have helped feed the planet but can leech out nitrogen into the environment, so how do we better manage and improve the nitrogen cycle.

Episode 340 - Insects revolutionizing agriculture

Insects are often thought of as the enemy of farmers, but they can help improve farming. From helpful worm pheromones, to farming crickets and hungry termites. Worms can help boost the resilience of crops like wheat, corn and maize to common threats. Worm pheromones help plants fight back against bacteria, viral and fungal invaders. If insects are the super food of the future, how do you successfully farm them on a large scale? What nutrient rich feed do insect farms need to give their herds? If you are growing crickets and locusts do they need different food? What food is best for termites and how can they be used to help better manage forest?

Lagrange Point Episode 337 - Stopping deforestation, saving species and conservation

As the climate changes different species are at risk. Some will thrive and others will struggle, so how do we target conservation efforts to better protect at risk species? Deforestation is a big issue in developing countries, but is there a win-win for the population and the planet? When sea levels rise, we think about flooding and erosion, but not what will happen to the forests and birds who live in them. Trees in the city live fast and die young, which means we need a whole new set of forest management techniques.

Episode 335 - Oceans, ocean size algae, deserts and fresh water in strange places

Water, water everywhere but not a drop to drink or nutrient for that matter. The Ocean can sometimes be a inhospitable place with barely any nutrients to survive off. Other times it can be home to large ocean spanning algae blooms. The oceans from the Pacific to the Atlantic can hold lots of secrets (even fresh water) beneath the surface. This week we look at 3 different papers which outline strange parts of the ocean, from large algae blooms to hidden aquifers.

Episode 333 - Saving which bees and where

Saving the bees has gotten widespread understanding, but it is more nuanced than a simple sound bite. Which bees are in danger and where? How many bee species are out there and are under threat? Can domesticated bees spread disease to wild populations? How do wild flowers help feed bees but also spread disease? Can different types of crop cycles help both wild and domesticated bees thrive? We know of colony collapse disorder and pesticides, but what other threats are out there to bee populations? Does the urban sprawl play a role in destabilising the gender balance of the bee populations? Why do bee populations drop off as you approach the city?

Episode 331 - Making modern technology less energy intensive

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?

Episode 327 - Hippos and Algae, Lions and Porcupines, plus Narwhals.

What connects Hippos, Algae and keeping the rivers of Africa healthy? What causes Lions to square-off against Porcupines? What is keeping the Narwhal population healthy despite it's genetic diversity? We look at the strange interconnection between species and how small changes in one ecosystem can destabilise a whole species.

Hippos help keep the rivers and lakes of Africa healthy...through their poo.

Hippos are essential in pumping silicon from the savannah into the rivers and lakes of Africa.

Lions hunt lots of creatures, but what needs to happen for them to try attacking a Porcupine?

Porcupines vs Lion sounds like a March Mammal Madness battle, but what causes a Lion to go after such a tough prey?

The Narwhals population is rebounding but it its still at risk due to it's shallow gene pool.

Can a species survive with a shallow gene pool?

Episode 326 - Capturing, reusing, recycling and cleaning water.

Water is essential for life, but we need to take care of the complete water cycle. Treating waste water can help remove harmful pollutants from cosmetics and medication. Industrial processes and landfill can also make super salty water, that we need to clean before releasing. Without good water management then we can end up without water in times of drought, and in times of flood more water than we can handle. This week we find out about ways to better manage the most precious of resources, water.

Episode 320 - Extinction events and their causes

Life has been around on earth for a long time, but there have been many extinction events that have wiped out large numbers of species. This week we find out how scientists peel back the layers of rock to uncover what caused these extinction events. Plus we find out about current extinction events and what we can learn from the past to protect species today.

Episode 319 - Changing lakes and rivers in the Antarctic and Arctic. Plus carbon capture and storage

Trying to understand how the climate will change is difficult. For every big event like the break up of an ice shelf, there are thousands of little factors that play a role. Sometimes this little things turn into a torrent of a river, or a calm lake which can cause an entire continent to bend and flex. We find out about research into the Arctic Tundra and it's changing lakes which are one of the largest natural emitters of greenhouse gases. Plus ways to capture greenhouse gases and store them safely.
