Elected moderator on Unix & Linux. Feel free to @ping me in chat if there's anything I can help you with.

I am a computational biologist with a background in biology, not computers. My PhD work was on gene prediction and comparative genomics but my current research is in systems biology, specifically protein-protein interaction networks.

comment Are there any known mutual symbiotic relationships that has more than two agents?
I'm not entirely sure that this constitutes symbiosis. It's a very valid point and +1 but I wonder if someone working in the field would consider it so.

comment what the best E-value cutoff in the miRNA homology search
10? Really? I haven't worked with miRs but 10 seems extremely high. In fact, working on short nucleotide sequences, I wouldn't recommend using the evalue at all. I'd go for plain %id and % coverage instead.

comment Find protein homologs with BLASTp
What species are you comparing? How distant are they? If close enough, "real" homologs should be able to form a single HSP spanning most of the target sequences.

comment Why don't fish groom each other?
@VatsalManot yes, but I think it's applicable to all. In order to be able to eat parasites, you need to be small enough to get at them. Presumably, if you're the same species, you will be too big. Still, as I said, this is pure speculation.

comment How to evolutionary explain menstrural cycles synchronization?
@Chris that's really interesting, I am aware of much anectodal evidence that suggests this is true. The wikipedia link you gave cites PMID:23480070 but I don't have access to it. Do you? Does it indeed confirm that it is a myth (the abstract suggests so but I don't know for sure)?

comment Local BLAST Copy Number per Hit
That depends on how you define a hit. Are we talking about homologous genes from different species? Multiple, slightly different copies of the same gene in a single genome? Multiple, identical copies of a single gene which is repeated in the database?

comment Why are the genomes of some trees so large?
+1. Another interesting point is that there is some evidence that the retrotranspositions of repetitive sequences such as Alu (which represents 10% of the human genome) are activated under conditions of cellular stress and can help shuffle the genome‌​, providing new variety.

comment Do blind people learn Braille equally fast as the sighted?
I'm not sure this is on topic here. It sounds like it might be a better fit for Cognitive Sciences.

comment What is the difference between embryology and developmental biology?
@tel I know, that was just a tongue-in-cheek comment pointing out why not all of developmental biology can be called embryology.

comment For how long can a raven stay airborne (a week or more)?
Quite apart from using a mythical story to ask a scientific question, I don't see what makes you think that the raven was flying around all that time. For all you know, and as seems more likely, it drowned. Could you edit your question, remove the biblical references and just ask something specific about an animal's behavior?
