Saddle sores and lil gold crystals

After a self-imposed hiatus of a quatter year or so, I'm back in the saddle, writing stories for Cosmos again. One of the secondary reasons for the break was to do some of my own writing, and I'm pleased to say that my production (if not quality) both here and at Hammertime's Brog has increased. The challenge will be to keep (get) it up.

So in the latest piece of dazzling research, scientists over United States of America way have bung together DNA and gold to form lovely, orderly lattices. Of course we're talking nanotechnology, a field that was massively buzzy a while ago but has kind of faded away in publicity compared to, say, biotechnology. Out of the public eye does not mean out of action though, and there is a mass of activity in the field at the moment. Expect to see the results permeate society in the coming decades.

For now, Nature still deemed the two articles which I wrote about worthy of front cover status, which is revealing in itself. Basically, the two teams stuck DNA (either single stranded or double stranded with an overhang) onto 15 nanometer gold particles. Take a bunch of these and mix them together, and the available base pairs of DNA will seek out their complementary base pairs and bind them nice and tightly. The result is nice and orderly little gold&DNA crystals, with different physico-chemico-electrico-whateverico properties.

Overall it seems scientists seem to be saying - screw nature, we're gonna build a superior product ourselves. This is a significant step on the way to doing so. Of course, there'll be a few unexpected twists and turns down the road, but that's half the fun, right? Who knows what disasters and scandals lurk out there in el futuro?

One thing I didn't get was whether they were planning on leaving the DNA in there, or getting it out somehow. And if they take it out, will the gold stay stuck together? I'm sure the scientists are on top of these questions. Overall very basic research, in the sense that applications will come a fair way down the track (I think). This heartens me, as a while ago I was convinced that governments were giving the finger to basic research in favour of applied research. Now I'm not so sure.
