Apparently no one told a group of whales in Antarctica that they were supposed to be seen and not heard. Instead, what scientists believe is a new whale species is doing the exact opposite.
Clams are threatened by predators who love seeing them served up on a plate drenched in butter and garlic, nestled in folds of fresh pasta–or splattered on a dock, if you happen to be a seagull. But a much more insidious threat to clams has emerged, in the form of cancer cells floating through the ocean.
From Jaws to Finding Nemo, sharks are most often portrayed as ravenous eaters. But even for these fierce marine predators, sometimes the hunters become the hunted. Photos taken during a 2012 tourist trip in South Africa are the only known documentation of a seal going after and consuming mid-sized to large sharks, according to a study published online last week in the African Journal of Marine Sciences. The discovery not only reveals a previously hidden part of one species’ diet, it could also have important implications for our understanding of the food web in the open ocean.
A group of researchers are getting closer to bringing the extinct woolly mammoth back to life. Geneticist George Church’s lab at Harvard University successfully copied genes from frozen woolly mammoths and pasted them into the genome of an Asian elephant.
