You know about fossils, but what other secrets are lurking in the ground beneath our feet?

I don't understand why videos such as this get 'dislikes'. Disliking factual information is ridiculous and illogical. Something to ponder: If one does not like truth, does that mean one likes being lied to?

Growing DNA found in antarctic ice... What could possibly go wrong? I for one welcome our new Cthulu overlord.

Sometimes I feel like this channels too good to be real.

If Sherlock Holmes could have analyzed this DNA he'd have said, "Sedimentary, my dear Watson and Crick."

Hi there, SciShow! I would love for people to learn about the terrifying and sudden nature of cerebral aneurysms! I had one rupture at 19 and I think it would make for an interesting video topic!

Soooooo how long until we are making Jurassic park?

Besides using sedimentary DNA, scientists are also trying the last few years to find DNA in aquatic environments. Unfortunatly, the longest DNA stay in water is about a month. So it will only be usefull for monitoring the presense of species.

Is there DNA in a DNA?

You forgot to mention in the PCR bit that forward and reverse primers are needed to synthesize the new DNA. You can't just plop in any DNA sample; you need specific primers to choose a sequence for replication and start the PCR at all.

Did you just assume my DNA sequencing pattern!?

Thank you for scienceing the shit out of my day. I like having something new to contemplate when I'm bored at work. Also, gotta say, I'm super excited about SciShow Psych.

my wife works for the company that makes the best kits for extracting, isolating and sequencing dna and rna taken from just such difficult to test sources. Their company was recently acquired primarily for that tech. It's very cool stuff and extremely interesting science.

I put my DNA in Plant's so I can grow my own child w/o the worry of child support.

This is so cool! I'm a soil ninja and I even haven't heard about this. I wonder how they target areas that would have more DNA and what horizons have the most.
