The California Condor has been brought back from the brink of extinction by dedicated conservation efforts over the past 30 years. Now, this critically endangered species is the latest victim of the H5N1 bird flu which is racing round the world. California Condor co-ordinator Ashleigh Blackford and wildlife veterinarian Dr Samantha Gibbs from the US Fish and Wildlife Service discuss their last-ditch efforts to vaccinate the birds against H5N1.

Huge 40,000 km plumes of water ice have been imaged erupting from Saturn’s moon Enceladus. Dr Sara Faggi, a postdoctoral Researcher in the Solar System Division at Nasa Goddard Space Flight Center, dives into this incredible new observation from the James Webb Space Telescope.

Dr Pierre Galand from France’s Observatoire Océanologique de Banyuls has been part of a two-and-a-half-year expedition to sample the microorganisms in coral reefs across the world. His new research shows that this tiny life is much more diverse than previously understood and may be essential to life of the coral reefs. And, much deeper in the Ocean, researchers estimate that there are over 5000 unnamed species in the world’s largest mineral exploration region, the Clarion-Clipperton Zone. Muriel Rabone, data and sample co-ordinator, and Dr Adrian Glover, merit researcher, both from the Natural History Museum in London, talk to Roland about this region of stunning biodiversity and the hope to protect it.
