Yes, but can you hear them scream?

There's a lot of science out there. Like, a real lot of science out there. And it gets published. Such as this paper, sent in by Ford Prefect:

Gorgiladze GI. Regenerative capacity of the planarian Girardia tigrina and the snail Helix lucorum exposed to microgravity during an orbital flight on board the International Space Station. Dokl Biol Sci. 2008 Jul-Aug;421:244-7. No abstract available.

Ford notes that:

It's unfortunate that this paper has no abstract and is published in a russian journal that I don't have access to (and presumably, is written in russian). The people outside the eastern bloc just aren't going to be able to know the answer to this pressing question...yet.
