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. Science Friday recently spoke with Poinar, 79, now a courtesy professor in the Department of Integrative Biology at Oregon State University, about what led him to investigate specimens trapped in amber, his thoughts on de-extinction, and his inspirations.

George Poinar, Jr., emeritus professor of entomology at Oregon State University and the man who first suggested amber could trap ancient DNA ( Jurassic Park style) says that he and his team found an unusual wingless female insect trapped in an amber chunk. This fossilized tree resin was collected from mines in the Hukawng Valley of Myanmar. They described their findings in the journal Cretaceous Research.

We sectioned the cells using a focused ion beam, which is like a really high-powered, ultra-small knife and we stained the nuclei to see if there was any DNA - but we didn't find anything. Michael Crichton, author of the book that inspired the movie, got the idea from the work of paleobiologist George Poinar, Jr. In 1982, when he was a professor of invertebrate pathology (within the Department of Entomology) at UC Berkeley, Poinar and his electron-microscopist wife published a study describing their discovery that amber could preserve intracellular structures, such as nuclei and mitochondria, in an organism trapped inside (in this case, a type of fly). I was naturally attracted to nature. It started with birds first. When I eventually went to Cornell, I decided I was going to major in ornithology. I started out with Dr. [Charles] Sibley there, and after working with him for a while, we decided that I should take a minor. I moved over and I worked with Dr. [Loren] Petri in botany for a while. And then I had an opportunity to do some summer work with an entomologist. That’s when I first became interested in insects.The functional form of the AMBER force field is [2] V ( r N ) = ∑ i ∈ bonds k b i ( l i − l i 0 ) 2 + ∑ i ∈ angles k a i ( θ i − θ i 0 ) 2 {\displaystyle V(r The idea that we may one day find a mosquito or biting fly from the Mesozoic with some parts of the blood still preserved is not outrageous,' says Susie. Blood in dinosaur fossils When under specific circumstances blood does preserve, it doesn't mean that scientists will find DNA in it. So even if a dinosaur's blood was found inside an ancient insect, an opportunity to recreate the reptile from it isn't guaranteed. This means that even if we miraculously had some DNA of the ancient creature, there are currently a ton of technical problems that prevent the cloning similar to that in Jurassic Park from becoming a reality. Assembling a full genome from DNA fragments requires us to have an understanding of what the whole genome looks like (which we don’t have in this case), and turning that into a living, breathing animal would necessitate putting that DNA into an ovum of a living species very closely related to the mystery creature that we don’t know in the first place. So looking for these various pathogens—it’s been kind of a goal of mine, because I feel that they can show how these organisms evolved over a long period of time, even long before humans entered the scene.

In the 20 years since the movie Jurassic Park fantasized about how dinosaurs could be cloned from blood found in ancient amber-trapped mosquitoes, fossil collectors have been on the hunt for a similar specimen. Over the years, a few different groups of scientists have claimed to find a fossilized mosquito with ancient blood trapped in its abdomen, but each of these teams’ discoveries, in turn, turned out to be the result of error or contamination. For many, the Natural History Museum is a place that inspires learning, gives purpose and provides hope. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists. To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery. Understanding and protecting life on our planet is the greatest scientific challenge of our age. And you can help.
