The BBC got a secret visit to a newly discovered fossil site somewhere in the US which scientists reckon could keep them busy for many years. Jon Amos got to have a tour and even found out a tasty technique to tell a fossil from a rock.

Bioflourescent Aliens

Researchers at Cornell University’s Carla Sagan Institute report their work thinking about detecting alien life on distant planets orbiting other stars. Around 75% of stars are of a type that emits far more dangerous UV than our own sun. What, they argue, would a type of life that could survive that look like to us? Well, just maybe it would act like some of our own terrestrial corals, who can protect their symbiotic algae from UV, and in doing so, emit visible light. Could such an emission be detectable, in sync with dangerous emergent UV flares around distant suns? The next generation of large telescopes maybe could…

Exopants

Jinsoo Kim and David Perry of Harvard University tell reporter Giulia Barbareschi about their new design for a soft exosuit that helps users to walk and, crucially also to run. They suggest the metabolic savings the suit could offer have numerous future applications for work and play.
