I don't thinks so. The proof of work needs to be tied to the block. It also needs to be very quick to verify but hard to compute (like getting a hash under a certain value). With scientific problems, you may need to solve a problem, then ever node on the network solves the same problem to verify what you did - which would waste a hell of a lot of resources!

We actually just had a double spend try and happen to us. I cannot show you the links, because the blockchain already ignored them. What happened was: We run a fundraiser for helping in the expansion of foldingcoin http://foldingcoin.net/fundraising/ http://foldingcoin.net/fundraising/ and we use a company called Vennd.io to help in this fundraiser. What happens is someone will send BTC to a certain address, and in return they are given an amount of 1 FLDC per every 0.00001 BTC they donated. Someone recently tried to double spend a BTC transaction to trick Counterparty into giving them double the FLDC in return for their BTC. However since the double BTC was denied, so was the double FLDC. I tweeted about it, but its no longer in the blockchain, here is the tweet https://twitter.com/FoldingCoin/status/558704804449771520 https://twitter.com/FoldingCoin/status/558704804449771520 when it was solved, and here was the first tweet about the actual transaction https://twitter.com/FoldingCoin/status/558073025468567553 https://twitter.com/FoldingCoin/status/558073025468567553
