Re: [DIYbio] Commercial DNA capsules - any experience? Useful or snake oil?

I remember watching an entertaining yet bothersome TED talk by a guy
who was discussing attempts to extract Dinosaur DNA from bones, and
the "challenges" they faced. Apparently they tried to dissolve the
bones to release the DNA with hot acid, suggesting they never
consulted with a molecular biologist first to learn about acid
hydrolysis. >_<

But yea, the proof is in the archaeology: DNA survives a long time
under pretty harsh conditions, so if you provide something remotely
cushy, you'll have DNA to spare.
