Suspended animation - the stuff of science-fiction, or a real-world solution to surviving long voyages into deep space?

The team explores what this could mean for future medical treatments.

Sand martins – known as bank swallows in North America - have returned to their breeding grounds. Ornithologist Bill Haines takes Rowan under his wing at the London Wetland Centre and introduces him to these remarkable tunnel-digging birds…

Wharton earth…? New research shows that Wharton Jelly, the stem-cell-rich goo found in umbilical cords can have important therapeutic benefits for those suffering from certain autoimmune diseases. The team discusses its recent success in treating Type 1 Diabetes. 

The Clarion-Clipperton Zone, deep in the Pacific Ocean, is of great interest to biologists and industrialists alike, as it is home to thousands of previously-unknown marine species… and replete with the likes of nickel, cobalt, copper, titanium and rare earth elements. As Matt explains, many of these species could be lost to deep-sea mining before we have a chance to discover them all.
