S2 Ep 30. Smart phones could become even smarter – thanks to ants, beetles, moths and spiders! A multi-animal special episode, marking the season 2 finale.

S2 Ep 29. Not all butterflies are colourful. The transparent wings of the longtail glasswing butterfly may hold the key to more effective eye implants. This could be of huge benefit to people with glaucoma - the second leading cause of blindness in the world.

S2 Ep 28. From goo to super glue! Slug slime may hold the key to mending wounds without stitches or staples. Scientists have developed new adhesives based on the properties of slug slime, that are as sticky as any glue, stretchier than a rubber band and aren’t toxic to humans. This sticky substance could be used to repair a delicate organ like the heart or lung without using methods that could damage the organ.

S2 Ep 27. The amazing agility of a dragonfly leads to the creation of a new spy drone. Their four wings can move independently of each other, enabling them to fly forwards, backwards, sideways, up and down and suddenly stop and hover like a helicopter. This caught the attention of engineers who wanted to develop a small drone that could be used by the military as a spying device. In the future, this sort of technology might send back pictures from areas where it’s too dangerous for humans to go.

S2 Ep 26. A very clever solution to a significant environmental problem based on a kingfisher’s eyelids. When the brightly coloured bird dives for food, its eyes are covered in a way that protects the kingfisher’s eyeballs, rather like swimming goggles protect ours. Architects have copied this design to help prevent soil erosion on the banks of the huge Three Gorges Dam in China.

S2 Ep25. Sweet moves! Honey bees have developed an extraordinary form of communication known as the “waggle dance”, which directs other bees to where the best nectar can be found. As more and more bees explore the area, their directions become more refined. This method of refining information has been copied into an algorithm to help delivery drivers save time and fuel, without the need to plot journeys by hand.

S2 Ep 24. The world’s most efficient swimmer is the moon jellyfish! It’s the inspiration for a soft underwater robot that is safe enough to use in fragile environments like coral reefs and aquatic archaeological sites. By contracting a ring of muscle, the jellyfish can push water out of their bell-shaped bodies, thrusting them forwards without using much energy at all.

S2 Ep 23. The science behind some fascinating fur could help humans keep warm in space. A polar bear’s fur is brilliant at insulating it from freezing arctic temperatures. Each shaft of hair contains multiple chambers which trap heat close to the skin, making it an incredible thermal insulator. Now, scientists have copied its structure to build a light and flexible material which may be useful for the aerospace industry.

S2 Ep 22. From heart stopper to heart saver? The electric eel creates energy within its body to shock its prey. Scientists are copying the electricity-producing cells of the eel to develop a new type of soft, fleshy battery which may be used inside the body to power medical implants.

S2 Ep 21. Take a peek into a camel’s nose! The science inside could help to cool desert homes. A camel re-absorbs the water normally lost in the breathing cycle, keeping its temperature down. An architect has copied this to create a system that could control the temperature of desert dwellings without the need for costly electricity.
