They've lived on earth for 280 million years at least, but starfish – or sea stars – remain a huge mystery in biology. Now, long-held beliefs regarding their unique design have been upended, as genetics reveal they're not all arms but nearly all head.

It's been called plain and boring, but this Thescelosaurus species has now had its sad reputation upended, thanks to fascinating sensory discoveries that suggest it lived a unique, successful life underground, beneath the feet of its fearsome predators.

Despite studies showing pigeons are smart, they are perhaps more widely perceived as unintelligent 'rats with wings.' But now, scientists have demonstrated how these efficient learners solve problems just like artificial intelligence does.

More than 17 million US households now have chickens. The world's first smart Coop, which is an ideal gateway to help novices raise chooks, has now rolled out Cluck Talk, which can tell you just what your chatty birds are saying to each other and to you.

Play is a vital part of animal behavior, helping to form social structures and bonds, develop cognitive function and enhance physical abilities. Now, it's believed whale play with seaweed to scrub off dead skin cells and parasites as they migrate.

Scientists have successfully extracted RNA from an extinct species for the first time. This was achieved in the thylacine, a species of carnivorous marsupial that roamed Australia until a century ago – and may again one day, if current plans bear fruit.
