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 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 382 - Animals keeping watch on our environment

Animals can help us monitor our environment for pollution. From silicon dog tags to tiger snakes in wetlands, animals can help us monitor pollution. How can silicon dog tags help protect humans from environmental pollutants? Cleaning up an oil spill is tricky, but with the right materials it's easy as wringing a sponge. Water hating but Oil loving magnetic sponges can help clean up after oil spills. How do Tiger snakes help us find the cleanest wetlands? Just how clean are urban wetlands?

Episode 371 - Marine Mammals vs Parasites

Its a battle between Marine Mammals and Parasites. How does an opossum parasite start killing sea otters?  In #2020MMM unexpected combatants can ruin your day, just like how opossum parasites are taking out sea otters. How does a parasite make a long journey from land to end up out at sea? Inside raw fish, parasitic worm populations are booming. This is bad news for marine mammals. Conserving marine mammals can be a delicate balancing act as parasite populations can also start to thrive.

Episode 365 - Wasps, Bees, tasty meals and pesticide.

From wasps to bees how are insects adapting to a changing world. What type of food do bees prefer? Can a bee be a fussy eater? What makes a tasty meal for a Bee and what would they avoid like the plague? What changes can be introduced into the microbiome by pesticides? How can pesticides change the microbiome of wasps and develop into resistance? Can pesticide actually make lives harder for themselves by building tolerance in insects?

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 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 328 - Mathematics and Nature, from Bees to Choruses of Frogs

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?

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 322 - Imaging strange objects in space (and on earth)

Taking images of strange objects in space is incredibly complicated and requires both large telescopes, and even larger teams of scientists to pour over the data. Techniques, codes and algorithms to sift through that data to find the unusual patterns is an incredibly difficult and challenging task. However with it we can capture some incredible things whether it be images of black holes, to asteroids literally spinning themselves apart, or even missing endangered species here on earth.

Episode 313 - Cross continent pop hits from whales and deep divers

The greatest pop hits can cross continents, but what about oceans? We all know whales make songs, but not only are they very complex, they can be covered, repeated and spread like a Number 1 summer hit across oceans to the far flung corners of the globe. Plus reaching the deepest depths of the ocean is tough for humans, but easy for whales. How do they accomplish these great feats? We also touch on the impact of naval sonar on the battle between squids and whales.

Episode 306 - Drones as a force for good and evil

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.
