Ancient DNA has so far been recovered from permafrost, as well as from subfossils - bones or body parts that have not yet fossilised. But DNA is vulnerable and breaks down rapidly. Sunlight has negative effects and water can also accelerate deterioration. Modern contamination is also a problem. DNA has to be handled under strictly controlled conditions. Currently the oldest DNA to have been found is around one million years old, although it is possibly younger. DNA 66 times older would have to be found to get to the age of dinosaurs.
A large, flightless bird, similar to an emu and native to both Australia and New Guinea, killed its owner when the man fell down on his property in Florida, authorities said Saturday.
According to The Associated Press, the Alachua County Fire Rescue Department told The Gainesville Sun that a cassowary killed the man Friday on land near Gainesville, likely using its exceedingly long claws. The victim's name was not released, but reports said he was apparently breeding the animals.

Apparently this is one nasty lil feathered critter not to be messed with. Up to four inch claws that will kill in one blow they say. A guy in Fla.was killed by one yesterday.

Somehow the vision of a Rex covered in feathers doesn't seem so frightening , well up to the point your being eaten i guess .

Well, I haven't heard that the Cassowary eats you. It's just a territorial bird. The remains are taken up by goanna, crows, meat ants and the Aussie Blowie maggots.

Melioidosis will,
Isn't that the wet season one , mud and all .
Going to space also appeared to trigger a genetic shift in Mr. Kelly. Thousands of genes that were once quiet increased their activity — genes that remained quiet in Mark Kelly’s body back on Earth. The longer Scott Kelly stayed aloft, the greater the number of genes becoming active.
Some of the awakened genes are known to encode proteins that help fix damaged DNA. That would make sense, given that radiation levels in the International Space Station are higher than on Earth.
Christopher Mason, a geneticist at Weill Cornell Medicine in New York, estimated that Mr. Kelly was exposed to 48 times more radiation than the average exposure on Earth over the course of a year. His cells might have been busy repairing radiation injury.
A number of other activated genes, however, play roles in the immune system. What exactly triggers those changes isn’t clear.
It may be the overall stress of life in the space station provokes an immune response. But recent studies have also shown that latent viruses can awaken in astronauts.
Or maybe it’s that the immune system, which never evolved for survival in space, simply gets confused.
