Great short film about how ILM's groundbreaking visual effects came to be used in Jurassic Park.
When Spielberg originally conceived the movie, he was going to use stop-motion dinosaurs. ILM was tasked with providing motion blur to make them look more realistic. But in their spare time, a few engineers made a fully digital T. Rex skeleton and when the producers saw it, they flipped out and scrapped the stop-motion entirely. Fun story.
Hold onto yer butts, you can use the computer interface from Jurassic Park right in your web browser.
It may look a little confusing but just remember: this is a Unix system and you know this.
Researchers in Copenhagan and Perth used DNA found in the leg bones of the extinct moa bird to determine the half-life of DNA: 521 years.
By comparing the specimens' ages and degrees of DNA degradation, the researchers calculated that DNA has a half-life of 521 years. That means that after 521 years, half of the bonds between nucleotides in the backbone of a sample would have broken; after another 521 years half of the remaining bonds would have gone; and so on.
The team predicts that even in a bone at an ideal preservation temperature of -5 ºC, effectively every bond would be destroyed after a maximum of 6.8 million years. The DNA would cease to be readable much earlier -- perhaps after roughly 1.5 million years, when the remaining strands would be too short to give meaningful information.
That means no real-life Jurassic Park, folks.
