Fossils like this are uncommon because of the unusual conditions required for soft tissue preservation.

Wow. Rearranging all that stuff was probably a lot of work Greg. It'll take some getting used to, but I think its an improvement. Thanks!

Meteorite impacts the moon:

I just found a summary article on early domesticated dogs in Europe in Science (the AAAS magazine). The first domesticated dogs (based on their DNA) were identifiable 14,300 and 14,200 years ago. Other possible domesticated dogs, based on fossil morphology, are not so convincing. When the...

Any experiment involving these Asgard guys would take a long time since they divide very slowly. There are probably special culturing techniques only a few labs would be doing regularly. It would be best to go to a lab that is already doing this.

Asgard archaea: have we found our microbial ancestors? The Ascard Archaea are now widely hypothesized to have fused with alphaproteobacteria (that became mitochondria) to form the eukaryotes (cells with nuclei and lots of internal membrane systems that form animals, plants and fungi). This...

No. Not an exception. There are many cases of cultured cancer cells like this. Their drawback is that their genome gets modified and becomes "weird". Yes.

Cancer cells are a convenience for people working with cultured cells (cells grown in labs outside of their normal bodies). They are a lot easier to grow and if kept in culture for a long time, they will be selected to grow better in those conditions. These things make them a good source some...

Its often unsettling when someone's querulous background surfaces.

This sorting of threads among forums in to fun and games did not come off as well done to me. There are some jokey threads left in the General Discussion: Programming Jokes: Lame, Science & Math Jokes! Bad Math Jokes These in General Discussion seem like puzzles (or games) to me: Mathematical...
