A chemical secreted by an animal, especially an insect, that influences the behavior or development of others of the same species, often functioning as an attractant of the opposite sex.
Given that pheromones are the primary opposite-sex-attractant, what proof is there that the insects will even have the CHANCE to mate. They most likely won't mate because the sterile insects probably won't produce as many pheromones to attract the opposite sex; and, thus not fill the void that is the container for the sperm in the femail insect. (Sorry, don't know the organs name.)
"We're talking about an impact on Europa, not on Earth. Europa doesn't have an atmosphere (at least, not one that is even comparable to Earth's.)"
The discussion is about impacting Galileo on Jupiter.
I used Earth as a model - a small model compared to Jupiter! If Earth's atmosphere can handle the breaking up of the craft to undetectable levels of radiation, I think the reaction of the craft compacting (and impacting (into, what? Gas for it's first 300 miles or so...)) into Jupiter would have an even less noticable effect. P-238 is not weapons grade plutonium. It's half-life is 87.8 years.
"Plutonium-238 is a non-fissile, alpha-emitting isotope with a half-life of 87.8 years. Given Pu-238 characteristics, it makes it the most capable heat-generating isotope. While selecting the radioisotope fuel, it was important to note certain characteristics: If the radioisotope has too short a half-life, it won't be useful for missions like Cassini, which is scheduled to last 11 years. On the other hand if the half-life is to long, the heat generated from a given amount of radioisotope will be too low, making the RTG heavier and larger. In order to protect people and electronic components within the spacecraft, it's important to avoid radioisotopes that emit gamma rays. It was found that Pu-238 met these requirements.">>
Halflife of P-238
Did you ever stop to think about how much radiation actually reaches Jupiter from other sources?
If Galileo were to explode over earth, it's RTG (Radioisotope Thermoelectric Generators) would have a negligible effect.
Worse case scenario on Earth:
Galileo explodes in Earths atmosphere. The RTGs break up into particulate form (the RTGs are designed using ceramics fused with the nuclear P-238). Everyone's nuclear exposure is raised by something like.001. You get more radiation exposure EVERY DAY from RADON than that of any fallen radiation from an exploded spacecraft like Galileo.

What is an RTG?
I can't wait to get them.
off topic a little,
I've got an old comic book with record of ST. It's called 'ST: A Passage to Mauve' or something similar to that. The comic is in pretty good shape but I can't seem to find any information about it.
Anyone know where I might find out about how much it's worth? It was printed circa 1972. I even tried contacting Paramount -- nothing.
I'd take it for the CB Radio alone!
When I was kid (about 16, I'm 33 now) I wanted to build a SUV and take it to South America to study fish in the Amazon basin. This thing is a dream come true!! I wanted computers, scientific equipment, all of it, installed inside with a chair running down the middle on lockable guides using a Chevy Suburban as the body. (Hey, there weren't many choices on the size of vehicle in 1985!)
Comms was never really an issue with me, though -- except to transfer my data back to HQ (Wherever THAT was! LOL )
At first I thought you might have been a little twisted in your thoughts and views, then I read the remainder of your argument. You know what? You'll get no argument from me!
Especially when it pertains to the music industry. The music industry, as a whole or individually, makes M$ look innocent. Never was there a robbing of peoples own works, right out from under them.
Maybe the musicians that startup will have enough computer savvy to invest in a CD-RW Stack (Expensive, true.) but then they'd be able to sell their own CD's. (Unless, that is, the record industry has managed to get the politicians against individuals selling their own music, and thus, the police out policing these hard core criminals.)

Dictionary.com define Pheromones as:

we type. Google takes notes.
Things that make you go, Hmmm!
infotech links works. anandtech.com links do not.
sorry for the confusion.
Don't waste your cycles on the above link by Mr. Darkness Productions, anandtech.com removed the article.
No Kidding! :-)
I linked to the page a few minutes ago and it takes ages to connect. I'd hate to have a 56K connection while trying to see this site!

I was thinking of the bay in which the good guys were building their vehicles in Jurassic Park II. I like it!
