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

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.

comment Is hunger pushing cognitive ability in humans?
Still it is curious for me because it is so counterintuitive. Most people I know if they have to work hard on a cognitive level they tend to snack nuts, chocolate, anything they are used to to keep their attention up. And this does boost your attention for a short while. The mild fasting on the other hand seems to be a more long-term approach (long-term being around 6 hours).

comment A free book/resource for learning genetics?
@Lohoris: Different countries, different "grad schools". Here I am, doing my PhD and being paid (not a huge amount, but well enough to survive for sure) for teaching and working on research projects. This is how it can work in Germany. There is also stipends and whatnot.

comment Do DNA supply houses maintain a watch list for dangerous oligos (Anthrax, Smallpox, etc.)?
I guess the fear is not necessarily to have someone produce a viable virulent anthrax from a DNA sample, but to have them introduce virulence factors of those watched pathogens into previously harmless organisms they could easily buy and grow.

comment Do babies resemble their father?
Most babies don't have a lot of (long) hair, while quite some of their mums will.

comment The Human Menstrual Cycle
This sounds quite a lot like a homework/exam question, so I added the relevant tag.

revised Is there a consensus on the CaMV 35S minimal promoter sequence?
The question in the title quite badly represents the questions in the text and make it less interesting for users
