Artificial Bases Added to DNA
holy_calamity writes "Researchers have successfully added two 'unnatural' DNA letters to the code of life. They created two artificial base pairs that are treated as normal by an enzyme that replicates and fixes DNA inside cells. This raises the prospect of engineering life forms with genetic code not possible within nature, allowing new kinds of genetic engineering."
We know what happens with the 'natural' bases--they indicate which amino acids are selected to produce which proteins.
I'm curious as to whether this will result in new kinds of proteins, or whether new amino acids will be required to be built, or what other effects might crop up.
It's interesting, don't get me wrong--but how -practical- is it?

This could be really useful in the long-term: if we could substitute replacement codons that work with most of our existing DNA, it's one step to building really tough DNA. Right now, there are a lot of damage mechanisms like adjacent thymines linking resulting from exposure to chemicals or shortwave radiation, and replacement codons engineered to not be suseptible to these could make, say, protracted exposure to radiation outside the Earth's protective atmosphere more viable. Of course, then we'd have to engineer a whole set of enzymes to synthesize those new codons, which is an extremely hard project, but finding things that work as replacement base pairs, now, gives us time to study how they might fail and figure out what the best candidates are.
Nostalgia's not what it used to be.
Even if its banned in the US, *other* countries will eventually start experimenting and create a super-race that works 80-hour-weeks without fatigue. Then other countries are going to have to follow to compete, or be left in the dust.

Plus, let's face it -- there are articles where the tag is wonderfully appropriate as ironic snark, but this one isn't it. I mean, it's great for articles like this one about mass production of micro fission reactors or this one about the proposed future of military robots. Sometimes, it's funny when the very proposition of something going wrong is itself funny like with an article on a robot controlled by a monkey's brain.
However, dangers and recklessness involved in this project are next to nil. There's no irony and clever cynicism here. There's just the mindless misapplication of an overdone meme in a manner that makes Slashdot look like a bunch of technology fearing idiots. So yeah. While I don't think it's worth getting so worked up about, it is a stupidly applied tag and a failed attempt at humor.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
I've been a frequent Slashdot contributer for 10 years and for some fucking reason not only can I not moderate, I cannot add tags.
I'm not sure what you're talking about. I didn't look through them all to see if any are more recent, but you tagged something as recently as Monday. Glancing through your tags, I have actually seen some of your tags up there; so it doesn't seem to be a matter of the tags not showing up. Is it that it just doesn't work sometimes? I've had that happen.
Right or wrong, with tags like "who cares", "thievingcunts", and "slownewsdaymeansdumbasfuck", it wouldn't surprise me if your 'tag karma' (or an arbitrary decision on the part of an editor) prevented you from tagging articles or from those tags showing up.
As for moderating, I'm with you. Excellent karma, frequent meta-moderation, and regular posting (in the past anyway) seemed to be a fast track to never having moderator points again for me.
