Merriam-Webster?
What's wrong with online dictionaries? You can try Merriam-Webster, for example.


"Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science." - Charles Darwin.

Did you know that most of the time your computer is doing nothing? What if you could make it do something really useful? Like helping scientists understand diseases? Your computer could even be instrumental in finding a cure for HIV/AIDS. Wouldn't that be something? If you agree, then join World Community Grid now and download a simple, free tool that lets you and your computer do your share in helping humanity. After all, you are part of it, so why not take part in it?

Re: book about vampire in space
Is this the book you're looking for?

Hint: Google is your friend.

Re: Bacteria Evolving Loss Of Function --- Example Please?
Look here

uanews writes:

A more recently discovered and less well-known aspect of genome evolution in bacteria is gene loss, in which entire chunks of the genome are deleted. "A region of a hundred genes or ten genes may have been lost [at a time]... these big deletions occur all the time," Ochman states.

Whereas gene acquisition can be beneficial, gene loss is usually catastrophic. However, in host-inhabiting bacteria, the protection of the host environment may allow the bacteria to survive such a loss.

"If you're a free-living organism, you lose a certain gene, if it's essential, you're dead. But if it's something that's not essential," for example a gene for the production of a nutrient you can get from your host, bacteria can keep living and reproducing after the loss, but they can never perform that function again. Further, because they are imprisoned within the host, they may have little opportunity to gain the genes back from other bacteria by swapping genes.

Again: Google is your friend.
