BSc in Biomedical Science, currently studying towards a PhD in Molecular Systems Biology.

I have several years worth of experience in web development and programming as well as basics of graphic design.

I'm a language nerd and a citizen science geek. I love techy stuff and wish I had the time to fiddle with electronics myself, but to that regard even building my own PC will have to wait for a while now.

comment What is this bizarre in-growth in this red bell pepper?
Hi there and welcome! The link you provided is very useful, but please expand your contribution into a proper answer to the question, otherwise I would recommend posting this as a comment only :)

comment Are neural connections one-way?
Dendrites don't transduce action potentials. They convert various inputs into membrane potential changes which propagate along them by diffusion towards the cell body. All incoming signals ultimately influence the potential gradient across the membrane of the axon hillock, where an action potential will begin if the depolarisation is large enough. en.wikipedia.org/wiki/Neuron#Anatomy_and_histology

comment What limits our healing speed?
The limiting problem is the formation of new tissue. New cells could indeed be produced faster, but forming tissue requires much more than just cells. It requires extracellular matrix to provide attachment for new cells, collagen and various other intercellular fluid components (which are secreted by fibroblasts), migration of cells. And bear in mind all of this isn't done on an open end, it needs to be done without actually at any point breaking the blood circulation system or other boundaries between tissue compartments.

comment How did people who were living far from the sea obtain iodine during the Middle Ages?
@ddiez I think iodine is a bit too specific to warrant a tag and thyroid hormones as a tag only indirectly describes this question; I think it's prefectly appropriately tagged

comment Machine learning for light microscopy — problems to solve?
Unfortunately exactly that :/ This question fits several of the "what not to ask" examples in the FAQ. (biology.stackexchange.com/help/dont-ask) You can of course bring these sort of things to chat! (link at the bottom of the page)

comment Why aren't introns found on the ends of pre-RNA?
Neither pre-mRNA or mature mRNA begin with exons, they begin with the 5'UTR. Are you asking why the sequence after the 5'UTR is always an exon? Or are you asking why there can't be introns before the 5'UTR?

comment Manufacturing of Bio Molecules
This is more about chemistry than biology (synthetic chemistry to be exact) and should be moved to Chem.SE in my opinion.

comment Why do I breathe out of BOTH nostrils?
If you're concerned, talk to a doctor - we can't give you medical advice here. Speaking biologically though, as you can read on the page you linked, we don't really know whether the nasal cycle serves any purpose. The only explanation I've heard is to reduce desensitisation of the olfactory sensors from overstimulation (basically giving each side of the nose alternating breaks). Assuming that, the only effect of a genetic variant that doesn't have a nasal cycle would be a weaker sense of smell.

comment Why sleep? No, actually, why wake?
Hi and welcome to the Biology part of SE! I think you're tying in a few different concepts here, and they're really more philosophical than biological. I don't think it makes for a good SE question, but feel free to join me in Chat and I can talk you through some of the basics that I'm aware of.

comment Chromatids in metaphase?
I would have guessed it's metaphase of Meiosis II but there should be only 23 chromosomes in that case.

comment Pharmacokinetics: why do certain drugs follow zero-order kinetics?
Hi and welcome to Biology.SE! We encourage making a decent attempt to answer questions before we make new posts - could you let us know some of your thinking that led to this question, and what part of it you couldn't find easily by searching the web?

comment Is it possible to convert nerve signals or electrical activity into a readable format?
You would probably benefit from reading up about how visual information is actually processed, you should then be able to formulate a more exact question. Keyword "visual pathway".

comment Can genes change as we age?
The contradiction is gone now - it was exactly the part after "I've never heard of any case" that caused that (because you then went on to explain a case that you heard of) :)

comment How much does a typical biologist know about signal processing, machine learning, and (theoretical) computer science?
I think this question could improve if you added the reason why you're asking this (depending on which it may or may not have an actual answer). As it is, you're just requesting comments and the StackExchange Q&A format isn't really useful for that. Feel free to take this to chat of course: chat.stackexchange.com

comment Can genes change as we age?
Where do you get that info about parental transmission of epigenetics in order to speed up /slow down the baby's development? You're contradicting yourself here by saying there's nothing, and then saying what there is. Aside from that, telomerase is active in germ cells and thus the transmitted telomere length will not be affected by parents' age (jcs.biologists.org/content/115/8/1643.full.pdf - it would be a bit weird if it was any other way)

comment Can humans survive without consuming life?
As long as the necessary nutrients are consumed orally and go through digestion, your gut flora and your own health should be fine. You could synthesise and consume indigestible carbohydrates (i.e. fibre) to support that additionally. His answer is an interesting thought though and does answer the question "Can humans survive without consuming life?" in a different angle.

comment Does a woman's G-spot actually exist?
The links you provide contain all the material you could likely get in an answer here. There's hence not really any use in asking here as you could just as well read the Wikipedia article and its linked resources.

comment Can humans survive without consuming life?
All organic components can be found in air and it is certainly possible to make them useful (plants do it too). Inorganic nutrients would need to be drawn from the ground but no live organism would need to be used or killed for that.

comment Can humans survive without consuming life?
I don't think we ever disagreed XD I felt like number 1) in my answer was what the question asked and so that would be the correct answer - but it's true that the question is sort of ambiguous and hence I decided to post this general answer.
