"Live a good life. If there are gods and they are just, they will not care how devout you have been, but will welcome you based on the values you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memory of your loved ones. I am not afraid."

comment Why Muscle Popups?
Hi Malic. At the moment your question is a bit unclear and relates to personal advice, which is off-topic on this Q&A (see biology.stackexchange.com/help/on-topic). If you edit your question and make it non-personal, and better describe what you mean by "muscle popups" then hopefully someone can help you. Otherwise this is likely to be closed as "off-topic"

Interesting point. No idea why cancers of the heart are so rare!

comment The damage of cancer cells
As you can see from the graph, it is not exact, but just a correlation between cell divisions and cancer - many other environmental factors affect cancer risk too, and some tissues may be more exposed than others? What makes you say muscle specifically?

No problem @MalicOfSdom. If I have answered your question please accept it. If you would rather wait to see whether others answer as well feel free, but vote up/down as appropriate, and accept an answer to help future users of this Q&A !

comment What occurs with mutations?
So is your question "Does increased replication rate lead to a higher likelihood of mutation?"

comment Parallels between pixelized image and the human retina
Interesting answer. In the field of view do the photoreceptors each connect to a single nerve? Roughly speaking how many photoreceptors may channel into a single nerve fiber, on average (unless there are actual values for different areas of the eye!)? This would ultimately be the smallest "resolution" or "pixel size" then, rather than the size of the photoreceptor itself. Thanks again

comment Circulating factors affecting human health/longevity
Thanks - did not know about oxytocin! There are other things associated with health (like IL6) but I am not sure this falls into the same category really.

comment Why are 3 nucleotides used as codons for amino-acid mapping in DNA?
This is very interesting information (sorry for delay in commenting). Could you provide any references/additional reading?

comment Statistical method for characterizing the relationship between body mass and metabolic rate
This is more a statistics than biology question, but before choosing a statistical test it is essential to visually inspect your raw data. Is your data skewed at all? BMI in the normal population already has a Gaussian distribution, and I expect metabolic rate also would - so unless you have a reason to log-transform I would not do this. For me there is nothing wrong with performing a linear regression to test the linear association between these traits, and then also test for any non-linear effects (perhaps by including an interaction term between them).

comment Can brain cells move?
Great answer. Glial cells (resident, supporting cells) also include resident immune cells, such as microglia, which are related to the monocyte lineage

comment Do larger multicellular organisms have an increased risk of mutation and thus cancer?
@Mew interesting question. Had a quick search and could not find a systematic study. The closest I could find is a report suggesting that BMI is positively associated with some adult cancers in humans (PMID: 18280327), however this could be confounded by a number of issues (>BMI could indicate unhealthy lifestyle? inactivity, smoking, drinking... only suggestions, but you can see what I mean). I can see that the logic of "large people have more cells" would imply higher cancer rates, but I don't see any evidence for this.

@Hurda I'm afraid not - I've not used them myself, just found them by searching on the internet. Find one with some good reviews!

comment Negative value on linear gene expression in microarrays
Anything below the background threshold is by definition an unreliable signal (i.e. detection P-value > 0.05). The 2 options for dealing with this is either to set values below the background threshold to "missing", or to leave them in but be aware that below the background threshold the values are no longer meaningful (you might do this if, for instance, 60% of your sample were below background for this probe, but the rest were above - this is still meaningful because it means that 60% of your sample express less than the 40%, so you do not want to set them as missing, as this may be relevant

comment Negative value on linear gene expression in microarrays
This is pretty spot on. The "intensity" values you end up getting are relative values to the background levels. These tend to be normalized to an arbitrary value - "100" could be the arbitrary threshold for background, above which you see a reliable signal. A probe with very low intensity could therefore be below 0.

The answer to (this question) may be relevant to you. I didn't see your question until now, and it is very similar to a recent question I answered!

comment What are the effects of muscle and fat mass on survivability?
Is this question specifically about resilience to falls/impacts? Or does this question also include disease risk? A major factor would be the age of the people in question... for instance, a high BMI is predictive of increased cardiovascular risk when younger, but in aged individuals (>65) a high BMI is actually protective, which may be due to an inverse correlation with frailty, or other complicating factor. Also, if you down-vote, provide a constructive comment for the poster.
