“That was quick,” Bill said, walking into the lab.
Miriam had the space spider laid out on a dissection table and was peering at a screen filled with chemical and biological notations.
“I thought you’d like to know what we were dealing with as soon as possible,” Miriam said. “But you might have to figure it out.”
“Why?”
“Because I don’t know if I’m figuring any of this out right,” Miriam admitted. “Some of it’s certain. This is a Class Four biology.”
“That’s Dreen,” Bill said, blanching.
“I said it was Class Four,” Miriam replied. “I didn’t say Dreen. It’s not Dreen. I don’t know where it’s from. It’s more like Nitch. The only thing that I can find that’s close to the design is Nitch but they’re Class Three. Alien unknown organism.”
“Great, we’re in quarantine for sure,” Bill said, sighing.
“Maybe, maybe not,” Miriam said, pointing to one of the biological readings. “There are no, and I repeat no, microorganisms in this thing that have any important effect on Class One biologies. So there’s no chance of us catching an alien space plague from it. The real biologists on Earth will have to double-check me on that, but this thing is the cleanest organism I’ve ever seen.”
“Not following,” Bill admitted.
“Okay,” Miriam said, sighing. “You have any clue how many viruses you’re carrying around right now?”
“None as far as I know,” Bill said. “I’m not sick.”
“Thousands,” Miriam replied. “And I’m not talking about individual bodies. I’m talking about species of viruses. Most of them have, apparently, no effect. Some of them might even be doing good things; scientists still aren’t sure about a lot of them. Then there’s your gut, which is packed with E. coli. Most… poop is actually E. coli bodies. Human beings are so chock full of little germs and bacteria and viruses and stuff that it’s surprising we have room for the muscle and stuff.”
“Didn’t know that,” Bill admitted. “But this thing?”
“It has four viroids,” Miriam said. “Best I can do on naming them. They’re not anything like our viruses. Class Four doesn’t even use DNA for one thing; it uses third juncture structures, closer to proteins, for genetic replication. The best description is that these are little packets that reproduce, but they can only reproduce on Class Four biologies and if I’m reading this right they’re some sort of enzyme producer that only attacks certain chemical structures. I don’t know what the chemical structures are, but they’re not human or other terrestrial proteins.”
“It was eating my cereal,” Bill said.
“Getting to that,” Miriam replied. “It has some more stuff in its gut. Not just its equivalent of E. coli but some bacterialike organisms. Closer in organization to Archaea but, again, using Class Four structures. Six of them. One of them can break down terrestrial sugars. You know how you can eat Adar food and not get fat?”
“Been on the Adar diet for a long time,” Bill said.
“Well, these can break down our sugars and convert them into its version of ATP,” Miriam said. “Badly. They can barely sustain themselves and it seems to release secondary materials that appear toxic.”
“So if they eat too much they die?” Bill asked.
“I’m not sure they die,” Miriam said. “I think they just don’t enjoy the experience much. I tested the toxins on some of the neurons that were still functional. The response, if I’m reading this right, looked like a pain response.”
“That’s…”
“Weird, I know,” Miriam said. “But it looks as if this thing would have little or no interest in, for example, entering terrestrial biologies and ripping them apart. If I’m reading all this right, it would find it actively unpleasant to try.”
“That’s good to hear,” Bill said.
“Yup,” Miriam said. “I even tried it on Adar food and got the same responses. I don’t have any Class Four biological material to test it on, so I don’t know what it would do to a Class Four biology. But all the biologies that we’re… friendly with don’t seem at risk.”
“All good news,” Bill said, letting out a sigh. “I was really sweating quarantine.”
“And you might, still,” Miriam said, looking at the enigma on the dissection table.
“But you said…”
“I haven’t gotten to the really good part,” Miriam said, waving the XO over to the table. She picked up a probe and spread the carapace, using the probe to point to a bit of purple stuff.
“What am I looking at?” Bill asked.
“Reproductive organs,” Miriam replied. “Here, here, here, here, here…”
“Uhmmm…”
“No,” Miriam said. “That’s not normal either. And all of them had some formed embryos in them. I’m not sure if they were dead or just… hibernating. Some of them seemed to be active for a short time. But this thing looks as if it’s supposed to breed faster than… Well, a hamster would go ‘Whoa!’ And they’re parthenogenic. Which means…”
“They don’t need other spiders to breed,” Bill said, breathing deep. “One of these things could…”
“Wipe out a world,” Miriam finished.
“I need a bottomline here, people,” Prael said, trying not to look at the linguist. He recognized, now, that he needed her. It didn’t mean he had to like it.
“I don’t think we can give one, sir,” Bill replied. “Miss Moon is not a biologist.”
“I’ve discussed the findings with Dr. Chet,” Miriam said. “He’s confirmed everything I found and does not consider them a threat. But it will be up to the science team on Earth to concur.”
“We’ve caught four more,” Bill said. “Miriam.”
“They’ve been given various Earth and Adar foods,” Miriam said. “Some of those are compatible with the Hexosehr. The only thing they’ll eat of Earth foods is cereal. They avoid the sugary ones, going for the blandest stuff we stock. And even then they don’t like it.”
“Put a big pile in the cage and they’ll go over from time to time, nibble on it, then lie down,” Bill said.
“And I was able to confirm that it’s painful for them to eat,” Miriam said. “They only do it to survive, poor things. I wish I had some Class Four biologicals to feed them.”
“I’d prefer that we keep their numbers down, Miss Moon,” the CO said. “They are still a huge potential biological hazard. Anything else?”
“They hibernate in vacuum,” Miriam said. “When exposed all their external openings close tight and they curl up. Their carapace is remarkably resistant to exfiltration. I don’t know how long they can maintain it, but I’ve put them in hard vacuum for fifteen hours and revived them. At this point, it’s how I’m storing them.”
“So we can’t even kill them by evacuating the ship,” the CO said, grumpily. “Where did they come from? Cheerick?”
“No, sir,” Bill said. “No way they came from Cheerick.”
“I think it was my fault,” Miriam admitted.
“How?” the CO asked.
“The asteroid mining,” Miriam said. “I think these things can last a long time in vacuum. Maybe for years or even centuries. There was probably one sitting on the asteroid. Who would have noticed?”
“Uh,” Bill said, shaking his head. “I think there’s a more probable explanation, if that’s the case.”
“Go,” the CO said.
“Last mission we got some material from a comet. We really didn’t use any quarantine procedures since what could you get from a comet?”
“Oh, yeah,” Miriam said happily. “I wouldn’t be surprised if they could get some nutrition even from comet ice. There’s a hint of complex organics in it! Wow! Glad it’s not my fault.”
