A unique 46-million-year-old mosquito fossil with a belly full of dried blood has been found in a Montana riverbed, according to United States researchers. “It is an extremely rare fossil, the only one of its kind in the world,” Dale Greenwalt, lead author of the study in the Proceedings of the National Academy of Sciences (PNAS), said.
Quick! Start up the centrifuge. Somebody fetch a frog.
Cutting-edge instruments detected the unmistakable traces of iron in her engorged abdomen, but just what creature that blood came from is a mystery since DNA cannot be extracted from a fossil that old.
Damn. So close.

Did you know that bananas cannot reproduce? That they are sterile hybrids created by a cheap low tech form of cloning?
Well we didn’t. We thought they were the actual fingers of banana monkeys. Shame on us.
The downside to this is that clones are, shall we say, not terribly genetically diverse. Turns out, a lack of genetic diversity is a great way to make yourself vulnerable to disease. Back in the 1950s, a fungus all but wiped out a variety of banana called the Gros Michael. Up until then, the Gros Michel had been the top-selling banana in the world. It was the banana your grandparents ate. You eat the Cavendish, a different variety that replaced Gros Michael largely on the strength of its resistance to the killer fungus.
The disease banana plantations now fear: Black Sigatoka, a different fungus that can kill trees and reduce yields in the survivors. The solution: Goldfinger, a new banana clone bred to resist Black Sigatoka.
And so farewell Cavendish, hello Goldfinger.
‘They were bigger in my day’, you’ll tell your grandchildren. ‘Sure there’s no aytin’ in these little yokes at all’.

Japanese and Russian scientists claim they’ll be able to clone a mammoth after discovering intact bones in Siberia. It’s not mentioned if the mammoths will be used by Vladimir Putin to hunt or as a replacement for whale meat in Japan.
