Enzyme Computer Could Live Inside You
dylanduck writes "New Scientist reports the creation of an enzyme-based computer that performs AND and XOR calculations, and combinations of the two, based on the presence or absence of specific chemicals. If they can be engineered inside living cells, they could measure a patient's metabolism and deliver just the right amount of drug at just the right spot, the researchers reckon. I'm worried about the viruses." Ba-dump *chink*.
If the "computer" can do more than simple combinatorial logic, what controls the flow of execution?
Random chance encounters with the right substances??
Thanks - I'll wait until version 2.

Oh wait...
will it run Linux?
Funny sigs make your Karma go down.
My guess is that they instinctively think "Ooh, it's made of enzymes, instead of all that nasty enzymes and electricity, so it must be better to put in people." But then we've been putting pacemakers etc. in people for years without any problems. And if they're suggesting that these wouldn't be self-enclosed units and would actually interact with actual human enzymes that may come and go as they please... then they've got a lot of contingency planning and 'wiring' work to do...
I don't see this having any real impact for a long while yet.
My, that was a yummy potato!

I think it is called the brain. Although it might work a little bit differently that what they are doing.
Are these researchers ranchers by any chance? When I hear the word reckon, I imagine some cowboy talking about herding cattle, not scientists creating wonder drugs and biological computers.

I had a brain storm about an idea for a sci-fi short story in which a team of college grads figure out a way to turn their dna into computers. This would enable them to form huds in their mind and use their brains for neural computers instead of say... Cybernetic implants...
Then one student learns how to break the code and then start to modify all his DNA and becomes a superbeast consuming all life and then the good guy nerd transforms into some physic dragon ball-esque character (who can also modify his dna to turn into a female supermodel) and fights it out in an anti-clamtic battle and then my story goes down hill from there... So I sort of never bothered to even to try to start writing down the story.

Isn't it supposed to be the sound of a drum cymbal zonk? Like during standup comedy there is a guy from the band that just played, or is waiting to play, or is providing musical accompanyment that goes "badump *pisssh*" (kick, cymbal or something a drummer will inform us of, but that *pisssh* sound)
Seriously zonk, I don't want to make you feel bad, but there are like a zillion people more qualified than you that would happily do what you are doing for free. I don't know how you got there, but I suppose that's a special skill in itself that you must have (or someone you know or sucked up to).
Slashdot has gone downhill, I mean it's obvious why zonk was appointed, cause the other editors (as they have openly stated) don't give a damn about spelling, proof reading, checking links or anything. If they appointed someone with half a clue it would have made them look bad. Oh well.
I will await people pointing out my spelling mistakes and using the "don't come here if you don't like it" argument. Thank you for your time.

Hey, it's Friday. Gotta have some fun.
The Overrated mod is for reversing inappropriate, positive mods, not for voicing disagreement with a post.
Therefore, an enzyme-based computer will not "live" inside you.
It will only "function" inside you.
Yes I know it is just a detail, but since we are all-grokking geeks we should hold ourselves to a higher standard.

Raymond Wurzveil has been writing for years now on the coming merger of man and machine (as in his highly recommended book The Age of Spiritual Machines ). The general idea is that eventually our minds will be transferrable to silicon and external means of storage, but this idea of humans being augmented with biological computing is an interesting short-term solution. I wonder if he'll make some comment about it.

I'd say Willner's thinking small (if you don't know who Willner is, then RTFA). Why make cures for sick people, when there are rich people out there who want to get fixed, too? I mean, if you can make a computer that would make you thin, or muscular, or change your hair colour permanently, or stop hair production in your legs... then go for it and make a ton of money. Heck I'd pay for something so that I didn't have to wax my back...
Worrisome, though, is the computer that you accidentally ingest that has a real bug, like, say, a Y2K bug (if that had actually been a big deal).
Maybe you use crappy hardware .. I havent had a reboot worthy crash in XP in years. Actually I cant even remember ever having one. Apps may crash on occasion but never the whole OS. Maybe you are using old or non standard hardware with driver issues? My boxes have over 512 MB RAM etc. Plus an HD with gigs of free space for swap etc.

Slashdot editors should think before using words in the article.

They are assaying some enzymes in vitro and are speaking of a "biological computer"? This is not really fascinating for a biology undergraduate like me.
"Protein engineering" is much more interesting! Customly made proteins which perform specific operations in the body of an organism.

Now, with that out of the way: i'm wondering whether this can be turned to practical application in the near future with cancer treatments. How far away is this?
And what happens if the markers used go awry? How easy would it be to end up with the wrong dose in the wrong place? I know if this were being used on me, i'd only agree to be an 'early adopter' in one of two circumstances- illness with a high risk of fatality, in which case the risks of treatment would outweigh the risk of dying without it, and very minor complaints with very safe remedies, because that way the risks even in the even of misfire are still low.
That leaves a lot of room for serious illnesses to go untreated in the middle, so i'm going to be very curious to watch this technology and see what happens with it.

Take it from a musician: bass drums (or toms) don't go "dump", and cymbals certainly don't go "chink".
I was looking into doing research into these and DNA computer systems when I first started looking into going to grad school a few years back. Essentially, things are still (after 5 years) only at the very basic levels. Work in vitro (outside the body, in a tube) isn't at the 'fully functional' level yet and until you can make a progammable style 'computer' that works in a tube...it's simply not ready to be put into a person where one error in genetic code could result in life threatening consequences.
And, once there...removal may be fairly difficult if something does go wrong. All in all...decades and decades away.

Many forms of virus do in fact reproduce themselves by hijacking enzymatic processes in living cells. The idea of a virus subverting one of these computing systems would be a very real concern. The terminology appears to have come full circle.
This is great especially if it could potentially lead to letting people live normal lives such as SLE/Lupus victims. It could actually stop people's immune system from going haywire and tell the virus tagging proteins to stop targeting healthy tissues for white blood cells to destroy. My knowledge of lupus is limited to peer reviewed published research and 2 female friends. It's odd to know at least of 2 sufferers, because they so rarely acknowledge it to *anyone* especially at work or with relatives.
The complexity of biochemical pathways has to do with differential concentrations of substrates and products. These enzyme logic systems sound like they have the potential to "light up" cascades of cellular "output". Very cool tools, from a research perspective.
Perhaps this technology could be used to examine some of these pathways in more detail: Cellular metabolism - gluconeogenesis, citric acid cycle, stuff going on in mitochondria and chloroplasts, diabetes, etc.
Cancer - Pathways of loss/gain of function mutations which result in tumor formation
Make no mistake - systems like these have the potential to "hack the cell" in a much more standardized fashion.
where'll they put the fan? Wait, I don't want to know.
The team built their computer using two enzymes - glucose dehydrogenase (GDH) and horseradish peroxidase (HRP) They built it using horseradish? O_o

Much like gates in computers, enzymes can have certain thresholds where they activate. However, unlike computers, enzymes can be made to react sooner under different conditions, e.g. heat, cofactors, coenzymes.
Suppose a drug is implemented and given an enzymatic computer to trigger when it should be released. How do we know this will work across all of human physiology given the aforementioned factors that can alter the threshold of execution?
I'm skeptical that about this idea, but curious about how it could be implemented. I don't foresee it used in the near future.

I mean, who would go for chemicals when you have a *processor* putting those nuts to work? I don't know much about this issue, but I would imagine any tinkering in this particular area will lead to catastrophe. Just think:

Cell B: All processing threads halted, stand-by for eject.

Yes, it could. But it won't.
Diabetes checks would be radically simplified, imagine an age without blood sugar sticks. For sexually transmitted diseases, perhaps a computer could be created to tell you if you had one of the (n) most common ones the morning after. Patients with hypertension would always have blood pressure monitors, and those with heart disease would know what theier status was at the check of a computer.
If it's not used for tracking or behavior-monitoring purposes, I say it could be a very handy tool for patient and doc alike.

Enzyme based computing has existed for millions of years. *yawn*
For many additional details and references about these chemical computers, read this overview on ZDNet.
Drumrooooooooolllll.... cracker!
Apologies, pished, but after someone spotted that there was more RNA interacting in the body than DNA it was messenger for; why aren't people noting that we already run bio-computation devices.
Forget the why, we're already lousy at that bit. Why not? If there's a gain for little loss, nature tends to grasp and experiment along those courses. An RNA computer that computes and records in next-gen DNA is an ultimatley sensible thing for Nature to do. Not that hard either.
Never mind the gigantic neural hash lookup algorithm that we call intuition...
Humans annoy me. They won't accept there's a question *until* they have an answer.

I think most people criticizing this article are completely missing the point. The computer based on enzymes is not being built to compete with your desktop. It doesn't matter if its basis is unstable and slow. Bsw149 attempted to make this point but was mostly ignored.
-Imagine your cells in a certain organ system alerting you that the concentration of a needed medicine has fallen too low.
-Someone with Diabetes could get a read out of sugar concentrations without taking a blood sample.
From the article it definitely seems anything useful is a long way off... But I'm guessing the people involved aren't looking for a way to get more fps out of quake.
