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 Are cells really the basic unit of all life?
Also, please link to the sources of the papers that you mention and give relevant extracts of the authors conclusions about ribozymes being a life form (or otherwise clearly state that that is your personal interpretation of their results, which is absolutely fine, of course).

I disagree with your conclusions. Otherwise should we say that a virus or a prion is alive?

@LanceLafontaine: I do not think lack of a clear-cut answer is a problem per se. The impossibility of giving a proper scientific answer is, though (for questions on this website, that is). Calling on the possibility of undiscovered extraterrestrial life which is not cell based is like claiming you have an invisible, incorporeal, floating dragon who spits heatless fire in your garage...

comment What evolutionary mechanism caused felines to develop purring?
I guess the first question to ask is: "Why do cats purr?". If I remember correctly it is not really clear, so I doubt an evolutionary mechanism for it is known. As for the roaring I suspect that size matters.

comment Why do the sick and unhealthy trees leaf out first in spring?
@jmusser: the market value of the wood of a tree has nothing to do with its leafing time. A 1 year old willow may be as good to its environment as a 300 years old oak tree: we may find it more valuable, but that is economy, not biology. I suspect that the pattern you are seeing there has to do with age rather than "wood quality".

comment Why do the sick and unhealthy trees leaf out first in spring?
The question is not clear. How a species of tree would be better than another? Why would a willow be worst than a oak or a black walnut? I think you're mixing two things: sick vs non-sick trees and trees of different species with different leafing times.

comment Why is maintaining a circadian rhythm important?
Note that your body maintains a circadian rhythm whether you want it or not! You may perturb it (e.g. by not sleeping or flying in another time zone etc.), but the molecular basis of circadian rhythm is always there (although animal models where is not there anymore do exist).

comment Why do people dying of immune deficiency diseases appear sick?
@Dr.Dredel: Kaposi's sarcoma is a type of cancer, one can get it even without having an HIV infection. What you may be missing is that AIDS patients have a compromised immune system, but they still have an immune system.

@Harrold Cavendish: if you haven't done it before, forget about patching, it would be very technically challenging. I will try to write an answer later today, now I'm late for work!!! :D

@Dr.Dredel: Kaposi's Sarcoma gives cutaneous lesions, Pneumocystis Pneumonia gives fever, tachypnea, and respiratory distress in immunodeficient people.

@Christian: no, but you can release a drug specifically on those cells.

comment How do we know the brain flips images projected on the retina back around?
@mgkrebbs: OK, we agree. I just misunderstood your previous comment :).

comment How do we know the brain flips images projected on the retina back around?
@mgkrebbs: the retinotopic mapping of images in the visual cortex is very precise. There is no projection screen in the brain but the image is processed in a very precise spatial manner.

comment Robotic surgery for treating cancer?
@Christian: there are, however, (far from perfect) approaches to that, such as receptor-mediated or pH-mediated targeting of nanoparticles for drug delivery.

So, what is the exact question you are asking? The title asks something different from the question's body...

Can you patch? Do calcium imaging maybe?

comment Species with reproduction barriers that can both reproduce with a third species
Are you sure a Great Dane cannot reproduce with a Miniature Pinscher (e.g. through in vitro fertilization)? Anywat, crickets are not domesticated so they don't have breeds! Have a look at this: en.wikipedia.org/wiki/Species_Problem

comment Species with reproduction barriers that can both reproduce with a third species
All dogs belong to the Canis lupus familiaris species (which is a subspecies of Canis lupus, that is gray wolf). Great Dane and Miniature Pinscher are not two separate species, but rather two different breeds. A better example would be horse and donkey, different species that can mate to give a mule.
