comment What is the number of cells in a line of a fingerprint?
@math4tots I agree that the needle isn't a great size reference because the size of the tip isn't an "everyday life" kind of thing. However, I don't see why something has to be made up of cells to act as a reference for judging the size of cells. scaleofuniverse.com might be interesting to you for relating magnitudes of scale. Make sure to catch the human blood cells (~10 micrometers) between the micrometer and millimeter markers.

comment What is causing my problem with very low yields when isolating a 42kb yeast plasmid?
I took 1.5mL of a "dense overnight culture" for this protocol. I don't remember being particularly careful about the OD for this (and the OD is relatively strain-dependent anyway). For us, "overnight" meant the culture was in a healthy stationary phase and that was easily gauged by eye. If you need to get a feel for the growth properties of your strain, start a culture in the morning and take periodic OD600 readings throughout the day. That should give you a clear picture of when you'll have the maximum number of healthy cells.

comment How to typeset gene regulatory networks
+1 for Cytoscape. I found it useful for looking at gene interaction networks pulled down from the yeast genome database.

comment Is there a term for tool use in animals?
Yeah, I've never seen anything more formal than just plain "tool use". For instance, see the article "The Ecological Significance of Tool Use in New Caledonian Crows"

comment What are the constraints when growing an artificial brain?
A term from counting bacterial colonies comes to mind as an answer to this question: TNTC (too numerous to count).

comment Is it correct that the body only responds to the most painful stimulus?
I mostly interested if the postulate has ever been shown to be true in any case. Of course, I would also be interested if it happens to be applicable to the case of pain perception.

Is there any evidence that Ukhtomsky's postulate actually occurs?

comment Are there neurons that can sense light shining in your ears?
The study I think you are referring to appeared to find that shining light on the back of the knee could entrain a human's circadian clock (Campbell and Murphy, 1998). That study has been refuted by a later study (Wright and Czeisler, 2002, see comment by Baringa, 2002). Wright and Czeisler show no response to light behind the knees. Current consensus is that mammalian photosensitivity resides only in the eyes.

comment How do dopamine agonists like amphetamine/methylphenidate affect acetylcholine signalling?
In its current form, this question can be answered in one sentence by a simple Google search. Can you be more specific and expand your question?

comment Are there neurons that can sense light shining in your ears?
Can you provide a reference for a case in which a TRP channel, commonly thought of as a temperature detector, is plausibly used as a light sensor?
