MIT Researchers Harness Viruses To Split Water 347
ByronScott writes "A team of researchers at MIT has just announced that they have successfully modified a virus to split apart molecules of water, paving the way for an efficient and non-energy-intensive method of producing hydrogen fuel. 'The team, led by Angela Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering, engineered a common, harmless bacterial virus called M13 so that it would attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules. Over time, however, the virus-wires would clump together and lose their effectiveness, so the researchers added an extra step: encapsulating them in a microgel matrix, so they maintained their uniform arrangement and kept their stability and efficiency.'"

kinda like ice-nine, but backwards?
Is this basic, applied or vaporware research? (Score:5, Interesting)

Am I missing something, or wouldn't this be a huge benefit to the existing process of extracting drinkable water from sea water? One of the major problems with the current process is the energy costs. If this is a low energy way to separate the hydrogen and oxygen, it would be easy to filter and much less energy intensive to recombine.

All viruses have either RNA or DNA. If it doesn't have DNA/RNA it's not a virus [wikipedia.org] (2nd para).
Viruses cannot replicate without a host cell. However, it's quite possible to create viruses that are replication defective and cannot replicate even given their natural host. This is not a 'mutation' that can be undone but the removal of the entire sections of the viral genome: the virus remains able to infect (capsid interactions) but cannot complete it's life cycle. Initial replication is done with specifically spliced crossovers in a susceptible host cell.
It's all quite safe, and forms the basis of using viruses for both vaccination and gene therapy.
Now that's over with:
WHAAAAAAAAAAA! PANIC! WE'RE ALL GONNA DIE!!

And how many millions of years did it take to get back to normal? Do you think humans could continue to thrive for just one of those millions?

Homo Sapiens will either evolve into something (or several somethings) else, or die off entirely. Of course, we can argue that we've already managed to fuck up our own evolution pretty good; the number of our members who manage to breed despite incredibly crippling congenital diseases, tendency towards debilitating developmental diseases, or simply managing to survive their own ridiculous stupidity [southparkstudios.com] through advancing medical science, is staggering.
