Methylation analysis could tell them apart, since DNA from PCR isn't methylated. But most forensic labs wouldn't do this, and I think it would be very possible to frame someone in this way.

It's also a big component of fireworks – and every July 4th levels in lakes and rivers spike. That being said, this paper only presents in vitro data. Perchlorate may be more toxic than assumed, but the evidence isn't strong. htt

I wonder if this will affect the Hertz graduate research fellowships. I'd guess probably not.

The price of aluminum reflects the price of the energy needed to reduce it to the metallic form. Extracting from seawater would still need to pay this price.

The ancient Greek civilization was one of the only ones to have lost writing. Linear A and Linear B were the original forms; the current Greek alphabet was adopted later based on the Phoenician one. See: https://en.wikipedia.org&
