According to this paper m there are approx. 3.72x10^13 human cells in our body. Thats around 100000-times more cells than you estimated Accordingto this source (m) there are approx. 200 different types of cells, each containing 20 different types of structures or organelles. Interestingly, we carry ...

To me this thread reads pretty much like a psycho-social self-help group. Guys (and girls), step down a little bit! I think everyone of us, at a point, was pondering over similar existential questions (and if not, you should probably start now). But whatever the problems and questions are, the outco...

Hi, There are some papers reporting on bacteria that lyse sludge and/or other bacteria: m And to my knowledge, certain Bacillus species can also very effieciently lyse E. coli. These findings are certainly interesting, but keep in mind that the API test is somewhat limited- it is kind of a "qui...

Re: Evolution

For whatever "important" means in this context, but diversity is certainly vital for life in general to persist on this planet. There are numerous habitats and plenty of nutrient sources on Earth. In the course of evolution, life has found many different strategies to occupy almost all pos...

Re: most complex abiotic (nonliving) molecules

Lignin comes into my mind. Lignins are formed via radical-induced coupling of phenolic compounds and support the strength of plant cell walls. However, they are part of plant tissues (in trees), and they might not exactly meet your definition (?). But the lignin in a single tree is believed to be on...

Actually, yes. There are numerous examples in nature. In the course of evolution, protein sequences change more rapidly than protein structures. Many enzymes therefore strikingly similar structures, but are very different in their primary sequences. An example i just dug out from an old lecture, are...

Re: Science vs. Science Fiction, non-scientist needs help

Sounds like a re-make of "The Swarm" (http://en.wikipedia.org/wiki/The_Swarm_%28novel%29) which is a great novel, by the way... If you don`t know it yet, you should probably read it...

Re: Bacterial Calculation

Hallo, You don`t need a serial dilution calculator ... seriously. If you get 55 colonies at a 10^4 dilution, then you have 5.5*10^5 cfu/mL (in case you used an aliquot of 1 mL). If you count 85 colonies at a 10^5 dilution then it`s 8.5*10^6 cfu/mL, which is already close to the concentration you nee...
