Jurassic Park: Don't Hold Your Breath

Scientists recently found the intact blood of an extinct 20-million-year-old spider captured in amber. Unfortunately, they're saying they can't recover any DNA from the sample, which means they can't clone the disappeared bug. So the prospect of re-creating dinosaurs from similar blood samples seems to be "virtually nonexistent," according to the scientists.

I continue to hold out hope that genetic-recovery methods will improve in the next few years and allow us to bring back from the dead all manner of ancient fauna. Basically what I'm saying is that I hope to one day look outside my window and see some velociraptors traipsing down the street, even if it meant there was some chance that I'd encounter one in my own traipsing.

There are some other interesting angles of the research, by the way, despite the heartbreaking DNA news.
