Does it make more sense to measure the size/volume of the neocortex in relation to another part of the brain to make a rough index. We could then compare it to cetacean neocortex indices. As for the evolution of a neocortex, there are 4 theories for the ontology of this structure: epiphenomenal, dev...

The way I see it, and this could be erroneous, is that DNA makes proteins. Some of those proteins are for the cell membrane - transport proteins and receptor proteins for hormones etc... Other proteins are called enzymes which speed up, or slow down chemical reactions. Enzymes catalyse pathways for ...

Unbeatable Model of Human Consciousness

I have been reading about a new model for human consciousness, called the Penrose Hameroff Orchestrated Objective Reduction Model (Orch OR). It sees the brain as a quantum computer. The brain is not supposed to work like a laptop (algorithmic) but as a non-algorithmic device. This is possibly the be...

Re: DIY synthetic/artificial life

There are some links that I have on this subject re: synthetic life, namely two articles and one BBC news article that are (sort of) recent. Also: * Biohackery - DIY biology * [archived] DNA hack There is also an MIT website out there that has some DNA-based components that can be spli...

Is it possible that after all the microfloral processing in the digestive system, the reason for the smell is to stop other people from eating it? There seems to be a 'disgust' response hard-wired in the human brain.

Sperm aren't all that susceptible to heat once they've been made - it's sperm <b>production</b> that is mostly affected by excess warmth. And in a male, a LOT of sperm are stored in the vas deferens, out of reach of this technique. Agreed. But after this technique, would you be in the mood for lurve?

Isn't it the same with humans or with any other organism such as viruses? There seems to be a regression in each.

Have you guys hears of Endogenous Adaptive Mutagenesis? 'EAM holds that adaptation is reactive - that is, that it does not begin until after the environment induces an adaptive reaction in the organism. Also, it begins precisely at that organic point where the environmental pressure is applied, not ...

Reptiles developed the amniotic egg and internal fertilisation. there reproduction was truly water-independent. Since fertilization takes place inside the body of the female it does not require water(take note that external fertilization cannot occur on land - the eggs would dry up and sperm could ...

But these cases are quite less but not rare. dizygotic twins are unlike usually, and growth rate differes. Monozygotic are alike mostly and growth rate of one depends upon "nothing" but same. Agreed but monozygotic twins seem to have some 'link' between them as they mature that defies nor...
