comment Nature vs Nurture in Rooster mating dance: Are roosters lame dancers because they never learned any better?
I totally agree with you that the appreciation of beauty is shared, my idea is only that the perception of beauty might be completely different. Think of some animals that are attracted to smells or sights which for humans are disgusting.

comment Twin pregnancy, one natural, one surrogate, is it possible?
I am by far not an expert, but I heard in a clinical genetics lecture once, that invasive tests for genetic disorders have a risk of miscarriage, especially early in pregnancy. Therefor I would strongly guess that implanting another fertilised egg (which is invasive) is a medically unnecessary risk to the already growing embryo a doctor would not take.

comment Why would a venus fly traps mouth that's still “chewing” die?
A friend once figured that if his trap caught big ants, the traps often would blacken and die off. We guessed this could be related to the ants acid. My own trap that I had long ago used to "choke" on too big food and also have traps die off if they caught comparatively big insects. But all of this is just based on personal experience.

comment Nature vs Nurture in Rooster mating dance: Are roosters lame dancers because they never learned any better?
Maybe the hens think differently and do not see their roosters behaviour as lame? I mean, how is a human supposed to judge? Also, the hens have nothing better to compare to. So why the effort to improve?

comment Current understanding of abiogenesis
@ShanZhengYang The question you pose in your comment is answerable in a way where one can cite the most important (published in high impact factor journals and/or highly accessed/cited) publications. Then maybe you sort them in a timeline and there you have a development. It might not picture everybody's opinion on it, but it will picture how this scientifically developed and the answer can have a objective approach.

comment Current understanding of abiogenesis
While your question might be specific, based on the fact that academics are humans its answer will be primarily opinion-based and thus out of scope for this site anyway. Person X might think, they are on the top of the field and their area of expertise is one of the major research topics, but their favourite academic competitor Y might disagree and instead bring herself and her topic in the discussion. And now it is a discussion. Unless there is a publication (from a field like sociology?) which studied the "academics of abiogenesis" there is no scientific answer to your question.

comment What is this flower?
For the violet/purple I would guess it is some variety of petunia. (Sorry, I wanted to edit my comment but that guess came 1 minute too late to do so.)

Are you asking about the violet flower or the white/pink one?

comment Secretion in Gram negative bacteria
All we know, I would say. But that was not what I meant to point out. The mere existence of a secretion system does not mean there is something harmful to be secreted, or that it can be secreted into a human cell. Even if the "generalised system" is said to be able to secrete into a human cell, there might be mutations in some bacteria which change it into being less or more effective. Even if the secretion system is not mutated, the bacteria might need additional systems to adhere to a cell or adhere more strongly.

comment Why do humans find baby animals cute?
@GoodGravy Of course evolution is random, but a winning scheme means that it increases fitness, otherwise it would not be winning. Therefor selection is driving to preserve the winning schemes and they are conserved during speciation events. For a publication I don't have time today, but a fast search will provide you this: ncbi.nlm.nih.gov/pubmed/19175530 I remember there was another for dog/human and something explaining cats nursing ducklings.

comment What concentration of table salt is needed to kill bacteria in sweaty gym clothes?
I just wanted to throw in, that if you are using fancy gym cloths (made out of those nice fabrics which are supposed to help air circulation and such, I am not an expert on what they actually can do), soaking them in salt water might actually destroy your expensive gym clothes in the long run.

comment What is it that creates that wonderful smell after a fresh rain?
The fancy word for it seems to be petrichor. It has a nice wikipedia article which might lead you to some of the relevant publications. en.wikipedia.org/wiki/Petrichor

comment Is this species a variant of a red flour beetle?
Then it is from my understanding perfectly normal environment for a Melolontha melolontha.

comment Is hunger pushing cognitive ability in humans?
@rumtscho I was kind of looking for that biological answer, especially any additional explanation to the ghrelin theory from the newspaper article. I am not at all into cognitive science, so saw this as a biological (endocrinology) question.

comment How Scientists sequence, assemble and annotate plant genomes?
There is a variety of alignment tools, the most used and most widely known is BLAST. There is a web server at blast.ncbi.nlm.nih.gov/Blast.cgi but for complete plant assemblies or even all proteins found in one plant you would have to install and run it locally. In case you are not aligning pre-predicted protein sequences but want to align against RNA or protein databases, you would need a spliced aligner.
