A team of marine biologists affiliated with multiple institutions in Italy has found that some marine worms are able to survive in cold polar waters thanks to symbiotic bacteria that produce antifreeze-like proteins.
New research shows human activity is significantly altering the ways in which marine organisms are preserved, with lasting effects that can both improve and impair the fossil record. The findings are published in the journal ...
