Thomas Metzinger wrote an outline of his book, ‘Being No One’, which puts his theory of consciousness in a very brief, compact form. He puts forward a list of constraints that any system must have to be conscious. The first three constrains gives a simple form of consciousness which he then elaborates with further constrains. [...]... Read more »

PVC may have played a big part in our evolution... But, no I'm not talking about polyvinyl chloride (sorry to dissapoint!), I'm talking about the Planctomycetes, Verrucomicrobia, Chlamydiae (PVC) bacterial superphylum. And I'm talking waaaay back, when the Chlamydiae were much more innocent and hadn't got into that whole sexually transmitted disease scene.In a Science article, Devos and Reynaud discuss the possibility that that The PVC bugs, which appear to be a monophyletic group forming their ........

Insomnia is something all of us struggle with from time to time. Not being able to get off to sleep is perhaps one of the most frustrating and loathsome things in the world (second only to an itchy back).

The shadow of symmetry haunts physics. Symmetry is invoked to understand nature concisely, but broken symmetry is invoked to understand nature completely. Physics is filled with examples of shattered symmetries: there is more matter than antimatter, neutrinos only come in the left handed spin flavor, and quantum processes break symmetries constantly, but nature also violates symmetry in chemistry and biology in a very clever manner. Chemistry and biology are subjects I do no normally touch ........ Read more »

So, in the previous installment, we introduced the "Loudest Voice Prevails" principle, which describes the evolutionarily stable pattern of gene expression at an imprinted locus where there is an intragenomic conflict over the total level of gene expression. Basically, the allele that favors lower expression becomes transcriptionally silenced. Expression from the other allele (the "louder" voice) evolves to the level that maximizes its inclusive fitness. In this sense, the active allele at an im........ Read more »

Sometimes I'm going to write about rare cancers or blood diseases and sometimes I’m going to write about bad breath. That’s just the way I roll.
Halitosis literally means “condition of the breath” and has many causes and just as many home remedies. Original therapies (and by original I mean 1550 BC) like heavily herb infused wines didn’t remove the bad breath but like mints and other modern treatments they just attempted to cover the bad smell with something more pleasant.

Gene variants make anti-craving drugs a hit-or-miss affair.
Rather than taking on another broad hunt for the genes controlling the expression of alcoholism, noted addiction researcher Dr. Bankole Johnson and co-workers at the Department of Psychiatry and Neurobehavioral Sciences at the University of Virginia took a different tack. The researchers focused, instead, on investigating whether genetic variations among alcoholics might affect their responses to a specific anti-craving medication.

As I approach my third trimester, I’m becoming a bit of an omega-3 fiend. The unsaturated fatty acids have not only been tied to lower heart disease risk in adults, but they have also been shown to boost fetal brain development, especially when consumed in the final few months of pregnancy. Given that I’m not much of a cold water fish fan—the thought of chewing a mouthful of sardines makes me want to gag—I’ve been looking into how else to get them, and what I’ve uncov........

Doxepin is a tricyclic antidepressant drug with significant sedative effect recently studied for use as a hypnotic in the treatment of insomnia. Doxepin has strong antagonistic effects on several neurotransmitter receptors including the histamine (one and two), serotonin (two), alpha one adrenergic and muscarinic acetylcholinergic receptors.Juliane Weber and colleagues recently reviewed clinical trial research related to doxepin and insomnia treatment.
