In a study published Sunday, Nov. 5, in Nature Chemical Biology online, researchers examined symbiotic bacteria that live only in sea squirts and other marine life. These bacteria are responsible for making a wealth...

...portant fish species and harbor several species of sponges that produce chemicals with anti-cancer and other medicinal uses. Unfortunately, says Guinotte, just as scientists are finding out how diverse and important cold-water corals are, they are being threatened by a one-two punch. "First, bottom trawle...

More animals join the learning circle

... They apparently learn from group-mates how to use sponges to protect their snouts while scavenging (New Scientist, 11 June, p 12). But the evidence from killer whales is much more conclusive because the process was observed from start to finish. Some researchers have suggested that many purported examples ...
