Re: Re:

It matters in exactly the same way that evolution matters. The denial of free will is at least as irrational as the denial of evolution, both are observable. I still do not understand: how do you observe free will? I don't even know how to study that, because you can never go back and prove that so...

Re: Re:

... A neat move, not to disclose all the information you've got right away in order to obtain unbiased opinions from others. However, as it turns out, it seems you may know more about Bartonella than I do and thus I am not sure if there is much I can add that would be helpful to you. If you still h...

Re: Re:

I read that some cases can be asymptomatic, but perhaps something in between is unlikely? Transient bacteremia is possible in rare cases, such as sometimes with severe tooth infections that 'seep' bacteria into the blood stream. But I guess in these cases their numbers would be so few that they do ...

He thinks these are a micrococci - perhaps Staphylococcus. Actually, Staphylococci are not the same as Micrococci . Some species of Staphylococcus are important human pathogens, whereas Micrococci are opportunistic pathogens at best (or worst?) and normally cause disease only in immunologically com...

Re: Re:

If they were coming out as the blood cells die, could that allow their presence without being bacteremia? I suppose that could allow their presence in the blood film, although technically that is bacteremia then. Nevertheless, those dots in the smear still don't quite seem like bacteria in my opini...

I dare to say those are not bacteria. It is very uncommon to see bacteria in a correctly prepared blood film. If you had such a bacteremia that you can see them in your blood film, you would most likely be in a hospital now. And I assume you are not in a hospital :)

Re:

(usually if they are present, they are attached to other blood cells as 'satellites') This was perhaps an over-generalization; platelets do appear also as non-satellites. However, in my experience platelets often look more 'fuzzy' or blurry, so these still don't quite look like those. Also, they se...

With a quick look I doubt that they are platelets (usually if they are present, they are attached to other blood cells as 'satellites'). Not certain though, some more details about the stain would be nice indeed. Also, do you happen to have any images with white blood cells, this might give us some ...

As far as I know, fires caused by radiators are caused by electric radiators, not water/oil filled ones. Especially the water-filled radiators rarely cause fires, since the water is typically far below 100C and even if it were boiling, the pipes would burst rather than cause fire anyway. Or am I mis...

Neutral mutations, as per their definition, are neutral and have no effect so they are neither favored or penalized by natural selection. Of course it is very difficult to determine what mutations are truly neutral, but I guess the common definition is that we cannot see any effect caused by it (tha...

Re: Why must we avert the genome of Eden?

... I am having a hard time figuring out from where did this omnipotent piece of DNA pop up in the first place. Are you saying that out of nothing emerged the genes for an eye and a lung and an antenna and an anus, just like that? My spider sense is tingling... are you sure this is not just another...

The cells do not use the CO2 itself, it is for other purposes (see above posts). You may have success if you closely monitor the pH of your culture medium and adjust it when required during your culture. Normal cultures typically require maintenance every 2 to 3 days, but without a CO2 atmosphere yo...
