For those who consider (biological) viruses as a life, I am proud to announce (for those who didn't know yet), that humans have successfully artifically assembled "live" biological virus.

Yep, and it is only a small step from that to assembling a single cell organism, then a multi-cell thing, then a superior-to-humans being (in every way thinkable). So very soon we will no longer be the lord of the planet. I just hope that the new super-uber-trans-human-being-things will take better care of the planet then we currently are.

We would hardly "assemble" anything superior than us soon, other way than modifying ourselves. So, if such thing happens, it would be making ourselves better.

maybe will they need the knowledge of assembly programers.

Object Oriented Genetics?

I like the way Craig Venter talks about this topic, and believe it's some of the most important work being done in science today. I'm amazed that they are moving beyond just replace parts of a cell.

my cad system is geared towards the developement of artificial life
3d computers, analog electronics and mechanical parts u will all be able
to define and manufacture them

Wonderful link bitRAKE, it's great to see advance from few Kb in document from 2003 that i quoted, to over 500Kb today.

OMG - Object Manufactured Genes Smile
What is 500KB? The video? Is there another PDF? ^o)

EDIT: Nice video btw Smile

500K base pairs.

I'm under the impression they have software which constructs base pair sequences through orchestration of cellular metabolism. Talk about a HLL compiler! Very Happy

(The caveat is that they don't always create programs that work - so, they create millions of them with slight variations. Literally, genetic algorithms.)

Can I draw some parallels here: 5.4kb, 1kb & 0.5kb mentioned in the pdf-document [vid ref#1] are measures of Kilo Base Pairs, not KiloBits (where A,T,C & G are mapped to 2-bit nubmers) which would mean (kilo=1000) exactly 5400 base pairs NOT 2700 as you would get packing in binary.

Am I on the right track here?

What are the letters he keeps talking about in the video [bitRAKE ref#1]? Are the letters bits, base-pair symbols or actual letters?

Madis: Right. One letter encodes one base pair. In practice, each pair consists of two letters, but for every letter, it's pair letter is fixed (A-T, C-G), so it's enough to save one letter, and you know the other.

if these proteins are paired, it's because hte dna duplicator cut it in two

and then, it will complete the half protein chain by complement all single proteins.

A T C G
T A G C

after, these proteins can be combined in basic shemes,:

val, glu, gle, lys, etc etc...

and then, ....

Yep, three base pairs encode one amino acid. In theory there is 4^3 encodeable acids, but in practice there is about 20 of them used. So chain of base pair triplets is translated into chain of amino acids, called "protein" - building block of organisms.

Hehee, I didn't mean to sound *that* stupid. I know my biology, and what A, T, C, G are and do. The kb wasn't a very often-used acronym in school, when we learned this stuff. Just the kb confused a regular kilobit user here.
That http://en.wikipedia.org/wiki/Base_pair helped - thanks Wink

Hmm, well I just hope that the knowledge of how to code DNA doesn't develop any more, if it falls into the wrong hands we could end up with 'The Andromeda Strain' Razz

And if it ends up in the right hands we could cure cancer.

Every technology has both good and bad uses. The problem is how much one may outweigh the other.

I believe in the basic concept of life, to continue to evolve and understand until we meet our creator.

Of course there's an equilibrium to technology, but I guess I'm stuck between the catastrophic evils that may(will) happen because of this or the possible creation of a superior being than our own.

Personally, I would love the latter. I believe also that humans were meant as cattle, slightly more intelligent, but not enough to keep living. We were meant for one purpose, to create a being superior than us, that would succeed us.

AlexP: What exactly has your creator done? Only big bang & physical laws, or also abiogenesis (formation of "life" from non-living material) on Earth?

Does your philosophy then embrace the notion that cattle also meet their creator? What about Pigs, Alex? Why were they placed here on earth, by your same creator? Hmm.
Why would an omnipotent force expect mere humans, (themselves little more than fodder intended for consumption,) to create some kind of new being of any kind--even a virus? Since this so called Creator of yours is omnipotent, why wouldn't HE simply wave his magic wand, or think important thoughts, and magically produce this "superior" being, instantaneously, as HE supposedly created us? Or maybe he already has, and these "superior" beings are already living among us? Maybe they are God's "chosen" people?
I normally prefer vegetables and pasta, but today, as a sign of my profound respect for your creator's "chosen" people, I will instead consume pork liver.
