How far can reductionist eliminative science go ? Are we ever going to be able to explain the complexities of intelligence down to the function of just one gene, or even the more closely examined Single Nucleotide Polymorphism?

I’m generally suspect whenever there’s an effort to explain the complex biological process of behavior, which involves more …

ScienceDaily (2010-08-17) — The most robust statistical examination to date of our species’ genetic links to “mitochondrial Eve” — the maternal ancestor of all living humans — confirms that she lived about 200,000 years ago. The study was based on a side-by-side comparison of 10 human genetic models that each aim to …

Let me qualify the sensationalist headline a bit. There’s probably not just any one gene that can be found to qualify someone as mentally disabled when mutated, however, what they’re talking about here in NatureĀ is a program launched in the UK that aims to identify mutations in genes different from the already known genetically based …

ScienceDaily (2010-10-19) — Researchers have found that the same genes have different activity patterns in the brain in individuals with different genetic backgrounds.
Re-emphasizing the importance of genetic background in mouse animal models of neurological diseases!
These findings may help to explain individual differences in the effectiveness and side-effect profiles of therapeutic drugs and thus have implications …

ScienceDaily (2010-06-18) — The pancreas has its own molecular clock. Now, for the first time, a new study has shown this ancient circadian clock regulates the production of insulin. If the clock is faulty, the result is diabetes. The researchers show that insulin-secreting islet cells in the pancreas, called beta-cells, have their own dedicated clock. …
