comment Difference between mice and rats
To compute exactly which genes are new in one of the species vs. their ancestor, you could use orthology data from omabrowser.org

comment Difference between mice and rats
Different species by definition have different body chemistry, else they could mate. However, identity on the gene level is probably similar to the man/ape difference of 98 per cent, so MOST body chemistry is identical.

No, it's explained by Family, a very complex stuff :)

comment Does sour food cause sweating?
Note that usual vinegar may trigger a grape intolerance/allergy and even seemingly "chemical" acetic essence may be in part extracted.

comment HDL- and LDL-cholesterol
Just to add that associations of high cholesterol with CVD are still not clearly established and probably never will be, as there is also good evidence against. This doesn't diminish that high fat diets (= probably more calories than you need) will lead to overweight with all associated risks.

comment Are the inverse problems of Systems Biology impossible to solve?
The problem is that you need good data to do good sysbio, and you need lab work to produce good data. You can't simply rely on electronic annotation of genes and even manual curation introduces too many errors. Then where do you get your enzymatic constants from. It's all garbage in, garbage out.

Another Brenner quote: "Systems biology is low input, high throughput, no output science" and I fully agree.

comment Does artificial heat (shower/tea) affect diurnal rhythms in humans?
Well if temperature follows optical input, then it's not the other way round, is it? With warming up your body, you may get all sorts of psychological effects that obscure the rhythm but you can't simply exchange cause and effect of the diurnal cycle.
