Invasion

"I'm glad you all are finally here," Eugene said. His blue chambray shirt was open at the neck and his knitted tie was loosened. His dark eyes darted from person to person. He was wired: a far cry from his bored condescension the evening before.

Sitting around the coffee table were Jesse, Nancy, and Sheila. On the table was the Tupperware container with the two black discs along with an assortment of potato chips from Jonathan's shopping foray. Jonathan was at the window intermittently peeking out. Pitt and Cassy took chairs.

"You know there's a shitload of people wandering around outside," Jonathan said.

"Jonathan, watch your language," Nancy scolded.

"We saw them," Sheila said. "They ignored us."

"Can I have everyone's attention," Eugene said. "I've had an interesting day to say the least. Carl and I threw everything we had at this black disc. It is incredibly hard."

"Who's Carl?" Sheila asked.

"My Ph.D. assistant," Eugene said.

"I thought we agreed to keep all this among ourselves," Sheila said. "At least until we know what we're dealing with."

"Carl's fine," Eugene said. "But you're right. Maybe I should have been working by myself. I have to admit I was skeptical about all this, but I'm not now."

"What did you find?" Sheila asked.

"The disc is not made of any natural material," Eugene said. "It's a polymer of sorts. Actually more like a ceramic, but not a true ceramic because there's a metallic component."

"It's even got diamond in it," Jesse said.

Eugene nodded. "Diamond, silicon, and a type of metal that we have yet to identify."

"What are you saying?" Cassy asked.

"We're saying that it's made of a substance that our current capabilities could not possibly duplicate." I "So say it in English," Jonathan voiced. "It's extraterrestrial, that's what it is." The reality of the

confirmation stunned everyone, even though everyone except Eugene had expected as much.

"Well, we've made some progress today as well," Sheila said. She looked at Nancy.

"We've tentatively located a virus," Nancy said.

"An alien virus?" Eugene asked, turning pale.

"Yes and no," Sheila said.

"Come on!" Eugene complained. "Stop teasing us. What are you suggesting?"

"From my initial investigations," Nancy said, "and I have to emphasize initial, there is a virus involved, but it hasn't come in these black discs. At least not now. The virus has been here a long time: a long, long time, because it's in every organism I tested today. My guess is that it is in every earthly organism with a genome large enough to house it."

"So it didn't come in these little spaceships?" Jonathan asked. He sounded disappointed.

"If it's not a virus, what's in the infectious fluid?" Eugene asked.

"It's a protein," Nancy said. "Something like a prion. You know, like what causes Mad Cow disease. But not exactly the same because this protein reacts with the viral DNA. In fact that's how I found the virus so easily. I used the protein as a probe."

"What we think is the protein unmasks the virus," Sheila said.

"So the flulike syndrome is the body reacting with this protein," Eugene said.

"That's my guess," Nancy said. "The protein is anti-genie and causes a kind of overcharged immunological insult. That's why the lymphokines are produced in such abundance, and it's the lymphokines that are actually responsible for the symptoms."

"Once unmasked what is this virus doing?" Eugene asked.

"That's a question that's going to take some work," Nancy admitted. "But our impression is that unlike a normal virus which only takes over a single cell, this virus is capable of taking over an entire organism, particularly the brain. So just calling it a virus is misleading. Pitt had a good suggestion. He called it a mega-virus."

Pitt blushed. "It just came to me," he explained.

"This mega-virus has apparently been around way before humans evolved," Sheila said. "Nancy found it in a highly conserved segment of DNA."

"A segment that researchers have ignored," Nancy said. "It's one of those noncoding segments, or so people thought. And it's big. It's hundreds of thousands of base pairs long."

"So this mega-virus has been just waiting," Cassy said.

"That's our thought," Nancy said. "Perhaps some alien viral race or maybe an alien race capable of packaging itself in a viral form for space travel visited the Earth eons ago when life was just evolving. They planted themselves in the DNA like sentinels that waited to see what kind of life might develop. I suppose they could be intermittently awakened with these little spaceships. All they need is the enabling protein."

"And now we've finally evolved into something that they want to inhabit," Eugene said. "Maybe that's what that blast of radio waves was the other night. Maybe these discs can communicate back to wherever they come from."

"Wait a sec," Jonathan said. "You mean that this alien virus is already inside me, like in hibernation?"
