Thirty years on - the babies judged negatively by their mothers

by BPS Research Digest in BPS Research Digest

If a mother has a negative perception of her baby when it's just one month old, there's a strong possibility that same baby will have attachment problems as an adult, thirty or forty years later. That's the claim of a longitudinal study that recommends screening new mothers to see if they have a negative perception of their child, so that any necessary action can be taken to stop the transmission of attachment problems from mother to child.Elsie Broussard and Jude Cassidy recruited twenty-six ad........

The Neuroscience of Anorexia Nervosa

by Dr Shock in Dr Shock MD PhD


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 [...]

Science blogs and public engagement with science: practices, challenges, and talking out of your ass

by Isis the Scientist in On Becoming a Domestic and Laboratory Goddess...

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

If graves could talk, Patrick Wall’s would be screaming (oh, and genes affect pain)

by Lorimer Moseley in BodyInMind


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’ [1]
Almost 25 years have [...]... Read more »

'Wasabi protein' responsible for the heat-seeking sixth sense of rattlesnakes

by Ed Yong in Not Exactly Rocket Science

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 »

The Cocaine Conundrum

by Dirk Hanson in Addiction Inbox


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 »

Maintaining change

by Bronwyn Thompson in Healthskills: Skills for Healthy Living


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.
Some critics suggest that any change obtained during a short-term programme (such as a three-week [...]... Read more »

Say Hello to My Little Friend

Brain scans read memories

by Mo in Neurophilosophy

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 »

Looking for a post-coital snack?

Sexual partners do not always represent a healthy meal…

Sexual cannibalism, where a female preys on her male partner subsequent to copulation, is exhibited in several insect and arachnid species. Many hypotheses about the evolution of such a practice suggest that it is part due to the nutritional benefits to be had from chowing down [...]... Read more »

Soft, wet and rather tough

by Lars Fischer in EuCheMS 2010 Blog

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 »

Evolving from Promiscuity to Monogamy

by Johnny in Ecographica

...despite the fact that promiscuous mating systems are the prevailing strategy in nature, environmental factors can push typically promiscuous species towards monogamy... case in point, a report published in the April issue of The American Naturalist details how the ‘mimic poison dart frog’ (Ranitomeya imitator) parted ways with promiscuity to adapt a lifestyle as the first scientifically recognized genetically monogamous amphibian. ...

High Arctic soil carbon underestimated

by Phil Camill in Global Change: Intersection of Nature and Culture



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.
A lot of us who study climate [...]... Read more »

The evidence is: status, communication training, and intrinsic rewards are positively associated with scientists communicating with the media

by Christina Pikas in Christina's LIS Rant

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. The evidence, however, does not support this view. This article is another in a series of communications based on a multi-national study of how scientists in several fields communicate with the media. (you might have seen [1] or [2]). This article only uses data from US scientists who were re........ Read more »
