I'm a researcher in neuroendocrinology

I'm interested in all that regards pattern recognition, time series analysis, rhythms etc.

My current research focuses in the exploration and modulation of the neuro-endocrine patterns that contribute to the generation of hormone pulsatility.

comment Cells created using differently aligned proteins
That seems extremely far fetched to do with current technology... in any case, natural aminoacids are called L-aminoacids and their "mirror counterparts" are the D-aminoacids. Maybe that can help with your search?

comment How do cellphones calculate heart rate?
@WYSIWYG: if you look at ~1:40 of the the Siggraph 2012 video you will see that the algorithm works for dark skin tones too.

comment If everybody DNA is different then how blood can match even with matching blood group?
Since the antigens are genetically encoded DNA IS the determining factor when it comes to a blood transfusion. Just not all of it.

comment How does DNA mess up
Transitions are transformations between purines or between pyrimidines (that is C becoming a T or viceversa and A becoming a G or viceversa). Transversions are between a purine and a pirimidine (the red arrows in the picture). You can also have so called "wobble pairings" or "non Watson-Crick pairings" such as C-C, T-G, A-C.

comment Conserved proteins are non immunogenic
@biogirl: most commercial antibodies are generated by injecting the antigen into an animal. Most used speciars are rabbits, sheep, goats, chicken, guinea pigs, rats and mice. You can get antibodies synthesized in bacteria as Chris pointed out, but I would say that is not the most common way nowadays.

comment If DNA has a half life of about 500 years, how can old seeds be planted?
+1 for showing that the Materials and Methods section of an article is as important (if not more) than its Results section.

comment Do vitamins help our memory?
Why the close votes? The question was a bit "bare", sure, so I edited it a little. In any case I think it fits this site very well.

comment Does a phenotype include the presence of a recessive gene
Hmmmm... no, that is not what a Punnet square does. A Punnet square gives you the expected outcome of a specific crossing. In any case the table in the question has nothing to do with it, aside from having some genotypes written in it...

comment Is it possible to create an experiment in house conditions to prove the existence of germs?
Agar is easily available online (~5 euros for 100 g on eBay). For how to make the plates, and a sample experiment see here

comment Why we have no enzyme to digest cellulose?
You make a good point. I think these questions also come from the wrong perception (which was evident in the original version of the question) that evolution is finalistic towards making a species "perfect".

comment Where are newly discovered medicines tested
Just to put all of this in perspective: this whole process (when properly done) can take around 15-20 years and a few billion euros.

@Ferdy: yes there is ncbi.nlm.nih.gov/guide/taxonomy

comment What is the difference between SNP and STR?
Exactly, one could have CACT CACT CACT (3 times) and someone else CACT CACT CACT CACT (4 times). SNPs, are mutations in one single base.

comment Why is there such an argument about evolution?
OK, sorry I did not understand that was the sense of your question. In that case, may I point you to this excerpt from Carl Sagan's beautiful book "The Demon-Hunted World"?

comment Why is there such an argument about evolution?
The fact that there is not, and there cannot be a scientific proof of God makes any (pseudo)scientific argument referring to God a moot point. If you want to explain something using science then you must stay in the framework of the scientific method. Putting God into the equation is a deus ex machina (pun intended) just doesn't work. You can of course explain evolution by means of divine intervention, but you cannot call that science.

comment Why are there different types of neurotransmitters?
Neurotrasmitters can also inhibit neurons, and they have a various range of actions depending on their receptors.

comment How does smoking, an environmental factor, cause cancer, fundamentally a genetic disease?
The fact that not everyone who smokes develop cancer does not rule out that those carcinogens be (amongst) the causes of cancer in those people who do.

"Smart" is an extremely subjective thing...

comment Are there any types of cancer that cause neurons to divide?
@terdon: new neurons can be born in the adult brain. The phenomenon is less important (in terms of numbers) compared to other cell types, but still it exists. Adult neurogenesis has been reported in pretty much all mammals (see for instance: ncbi.nlm.nih.gov/pubmed/16022595 ). To be honest, I do not know until what age this happens. Surely in the mouse adult neurogenesis is seen also even well after adolescence.
