One of the most striking features of those suffering from anorexia nervosa is their perception of their bodies. You can put them in front of a mirror and they will still tell you they’re to fat when in fact they’re skinny. A recent publication in Nature Proceedings has an explanation.
This explanation is based on the [...]

This week a couple of my Sciblings have been abuzz about an article published in some journal I'd never heard of... a minor impact journal...the Journal of Who Gives a Fuck Science Communication. Bora has a great break down of some of the major criticisms. Drugmonkey, one of the subjects of the "analysis" in this article, is also displeased and critical of the author's conclusions.I've

In 1986, Pat Wall and Steve McMahon commented on the folly of talking about nociception as though it is pain -
‘the labelling of nociceptors as pain fibres was not an admirable simplification but an unfortunate trivialization’ and
‘…pain is an integrated package of analysed results related to meaning, significance and imperative action’ 
Almost 25 years have [...]... Read more »

Take a whiff of mustard or wasabi and you'll be hit with a familiar burning sensation. That's the result of chemicals in these pungent foods hitting a protein called TRPA1, a molecular alarm that warns us about irritating substances. The same protein does a similar job in other animals, but rattlesnakes and vipers have put their version of TRPA1 to a more impressive and murderous purpose. They use it to sense the body heat of their prey.
Pit vipers are famed for their ability to detect the infr........ Read more »
Effective treatment remains elusive.
For addiction to cocaine, amphetamine, and other stimulants, the treatment picture has been complicated by the lack of any truly significant anti-craving medications. (See post, “No Pill for Stimulant Addiction"). The National Institute on Drug Abuse (NIDA) has yet to approve any medications for the treatment of either cocaine or amphetamine addiction.
Take the case of cocaine. Partly the problem stems from the direct effect cocaine has on dopamine transm........ Read more »

I’m sure we’ve all seen it. The person comes into a pain management programme, gets excited, does really well during each session, enjoys the company and makes huge gains – then the programme ends and — FIZZLE! It all stops.

What looks like a worm, is completely symmetrical in cross-section, and in the words of Dr. Peter Holland:

FORMATION of a memory is widely believed to leave a 'trace' in the brain - a fleeting pattern of electrical activity which strengthens the connections within a widely distributed network of neurons, and which re-emerges when the memory is recalled. The concept of the memory trace was first proposed nearly a century ago, but the nature of the trace, its precise location in the brain and the underlying neural mechanisms all remain elusive. A new study by researchers from University College London ........ Read more »

Sexual partners do not always represent a healthy meal…

Hydrogels are the only materials that have the potential to be used as a replacement material for functional tissues like cartilage, sinews or muscles. However, while the biological wet and soft materials have impressive mechanical properties and are generally very tough, conventional hydrogels are rather brittle and tend to disintegrate under duress. With one exception, [...]... Read more »

Most people have heard about the potential positive feedback of soil carbon on climate: As temperatures warm, soil microbes are more active and permafrost begins to thaw–both of which can hasten decomposition and the release of CO2 to the atmosphere. This, in turn, has the potential to accelerate warming.

Myths abound about how scientists do not talk with the media or communicate with the public and if they do so, it is only because they are required to by funders' "broader impact" requirements.
