remade; new directives followed one after another. Great masses of dry ice that were still not sequestered were being shoved around; then abruptly the shoving would stop, leaving dikes like contour lines on a map, curving all over the dim white landscape. This stuff had to get buried before temperatures rose any higher, or else it would evaporate back into the atmosphere and poison them all. Terraforming, they said, was becoming a murderous business.
All this was news to Kiran, and the next time he saw Lakshmi he told her about his new lodge team, and asked if he could join them the next time they made a trip down to the coast. She shook her head at first, then frowned, then agreed to it.
“Just go down there and see the town, learn the layout. I’ll let you know if I want you to courier anything there.”
So he joined his new team for a rover trip down to Vinmara. On the way down the enormous south slope of Ishtar, they passed another new town that was being built with a harbor on its empty downhill side; then they drove down some giant hairpin turns and descended at least another thousand meters, maybe two, before coming to Vinmara, also being built as a harbor town. This struck Kiran as indicating a pretty serious dispute over the future sea level, but his new team scoffed at the town they had passed as a futile statement, one that would have to install a swimming pool to front its harbor when the time came.
Vinmara itself was being more grown than built, it looked like, as it was made mostly of bioceramics, scalloping in rounded stacks around a waterfront. The seaside promenade or corniche would anchor an urban district, ringing the bay of the ocean that would someday be there. Above and behind the waterfront curve the city rose steeply to a backing ridge, already being covered with seashell shapes mostly white or beige, then trimmed with pastel blue in the Greek style.
“This is Lakshmi’s work, this town?”
Yes, it was a project of her part of the Working Group.
“And someone else is building that harbor town back up the slope?”
Yes, that was Shukra’s people’s town. They were fools and idiots.
“But don’t they know how high the ocean will go?” Kiran asked. “I mean, the water’s already up there in the atmosphere, right?” Gesturing briefly at their eternal blizzard. “Why wouldn’t the models get it right?”
His teammates shrugged. One or two were giving each other looks that indicated to Kiran that this question needed to be added to his Unsolved Mysteries of the Solar System file. It was a big file. One of the mates finally said, “There are choices to be made. Some basins flooded or not flooded.”
They took him to a sidewalk cafe backing the new seawall, overlooking another little marina standing over black rock. Each round table of the cafe had its own umbrella, despite the bigger umbrella of the tent over the whole town. They were almost the only ones there, at first; then others began to trickle in, and a trio of guitarists set up and began to play, after which people started dancing. Party in a dry marina, in a night-dark storm by an empty sea. The heat lamps were on, and if you danced long enough, you could even warm your feet up. Kiran kept dancing with someone from his new unit, a young woman-yes, the old male-female magnetism still the most reliable guide to sex, as far as Kiran was concerned; and he could see variants of that being acted out all over the dance floor. Actually it was often hard to tell who was what, and this gal in fact was half a meter taller than he was, and pretty masculine and assertive at that, and in response Kiran was ready to melt like a girl who wants to get pregnant that very night. Whatever! He liked looking up at her face!
He tried talking. “ Lyanhe? Shengren syingyu? ” Union? Stranger sexual desire?
“ Syin pengyu syingyu,” she said, mocking him.
New friend sexual desire, his spectacles wrote on the world in red. Even better!
“ Tyauwu,” she ordered him. Dance.
Extracts (10)
Take some carbon dioxide, ammonia, formaldehyde, hydrocyanic acid, and salt. Put them in water and heat. Reduce to hot goo at the bottom of the pan; add more salt water. Repeat until you have a thick broth containing amino acids, sugars, and fatty acids. Throw in seasoning to taste. Each reduction and rehydration will thicken the broth further, until it includes many newly created nitroglycopeptides, and they will begin to form the protopolymers you need.
Some of the fatty acids will have hydrophobic tails and will tend therefore to stick together aligned with each other. These masses are your protomembranes, which in the heat of your stove top will wrap into tubes, also spheres with holes in them. Inside these little tart shells, a stuffing of protopolymers will clump together in a variety of macromolecules. These begin the chemical breaking and joining we call catalysis.
Chemical patterns in your new stuffing will yield similar combinations most of the time, and these new combinations will match up chemically in ways that can be read off each other; so information is now burbling around in your stuffing, and into and out of the hole in the cell wall will come useful molecules for more reactions. Linking up with patterned molecules already inside, these characteristic actions are coded by the basic chemistry, so they will keep occurring. What began as small accidental connections will link together in patterned ways, until the same polymers are always replicated, creating information contained in the longest chains to have been cooked up. At that point you have ribonucleic acid, RNA, and you are close to being ready.
The new RNA encodes the making of proteins, which in their three-dimensional sculptural glory are capable of creating a huge variety of tastes and smells. “Division of labor” in the proteins and what they accomplish is one way to describe the proliferation of replicating forms, but also, it’s a richer brew; it tastes better; there are micro- tastes within the taste. Your RNA will turn amino acids into particular flavors. (The technical term among biologists is “translation.”)
Finally some of your RNA will melt together into strands of DNA, a more stable form because of its double helix. Then DNA will take over the role of protein expression, although by way of the creation of messenger RNA. (That would be “transcription.”) Information at that point will move from DNA to RNA to proteins, and the now living cell will reproduce itself, divide up functions in ever-more-versatile larger organisms, and so on.
You have cooked up life from scratch! Eat it with gusto.
