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?

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.

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.

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.

One of the futuristic technologies always touted is Hydrogen fuel cells. So why are they not everywhere? we look at the challenges in production,storage, and use of hydrogen from cars to factories. Plus we examine if our electricity grid will be able to cope with the drastic weather condition changes from climate change in the year 2100.

From the bottom of the ocean, to the earliest days of the earth, life has managed to not just survive but thrive. We look at several cases which change our understanding of the earliest life on earth and just what that might mean for understanding life on this planet and beyond. From moving life fossilised in mud, to using isotopes to study metabolism and discovering whole new methods of getting food, life continues to astound researchers with its inventiveness.

Drones being used for good, and drones being used for evil. We look at ways that drones can help biologists protect, treat, regrow marine damaged ecosystems. Including IVF transplants for the Great Barrier Reef, sea-grass disease hunting drones and even drones to detect camouflaged birds in forests. We also look into the science behind drone defense and how we can protect our critical infrastructure from rogue drones.

Solar Panels keep getting better, but what if we could have solar power even when it's very overcast? Plus is there a way to make concrete greener and less carbon intensive? What if one of those solutions also helped take care of waste product from Coal Power Plants? We look at innovative green technologies this week in Lagrange Point.

Dust storms can be hazardous, especially when they engulf an entire planet like on Mars. They can also carry pollution across national borders and contaminate wide areas. But Dust Storms may also hold the secret for how life can spread across vast deserts. This week we look at dust storms of this world and out of this world.

This week we look into three stories about how oceans tie our planet together. Our ecosystems are often linked in unusual ways that are not immediately obvious. Ocean currents can tie ecosystems across the world together, impacting migratory species, local environments and ecosystems. Sometimes these impacts are short term, other times they play out over years, decades and centuries.

The history of humanity is tied to the history of domestication. But we often overlook the rule of farming and domesticating grains which enabled huge cities to form. We find out about using modern day science to follow the journey of agriculture to today. Plus some of the future innovations we can implement such as Vitamin A rice.
