But a study published this week (October 10) in the estimates that DNA from bone has a half-life of 521 years: after that amount of time, half of the nucleotide bonds that hold it together are broken, and after another 521 years, those bonds are cut in half again, and so on.To determine this rate of decline, an international team of paleogenetisicts examined DNA samples from 158 leg bones belonging to three species of Moa, extinct giant birds from New Zealand. The bones ranged from 600 to 8,000 years old, but all had been preserved in almost identical conditions, which meant the researchers could make comparisons between the ages of the specimens and the state of the DNA.Based on their calculations, the team predicted that even under perfect conditions for DNA preservation, it would take a maximum of 6.8 million years for every bond to be destroyed.

And even before that time—after around 1.5 million years—the remaining strands of DNA would be too short to be readable. So a dinosaur bone, which would be at least 65 million years old, could never yield useable genetic information.“This confirms the widely held suspicion that claims of DNA from dinosaurs and ancient insects trapped in amber are incorrect,” Simon Ho, a computational evolutionary biologist at the University of Sydney, Australia, who was not involved in the study, told.

You can’t just refuse to be a person every day of the week, Nel. At some point you’re going to want to be a person and that person is going to need you to have kept up with the responsibilities of your life. That person wants to be a scientist. You need to study. At the very least you need to eat. Get the fuck up and do the things. Half-Life Scientist's View. I taught: There are Half-Lifes in which you are a Scientist in HEV suit (Gordon Freeman), soldier (Adrian Shepherd), security guard and there is only one missing: Half-Life in which you are an ordinary scientist that works in an ordinary Office.
