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

by Kevin Zelnio in Deep Sea News

What looks like a worm, is completely symmetrical in cross-section, and in the words of  Dr. Peter Holland:
“It has no mouth, no gut, no brain and no nerve cord. It doesn’t have a left or right side or a top or bottom – we can’t even tell which end is the front!” (quoted from Physorg)
Its [...]... Read more »

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?

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

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 »

AMS Climate briefing rundown

by Callan Bentley in Mountain Beltway

Yesterday I attended a climate change briefing hosted by the American Meteorological Society (in conjunction with NSF, AGU, AAAS, and the American Statistical Association). It was in the Hart Senate Office Building, but I didn’t see any senators at the briefing.
It was an interesting format: 3 talented speakers giving 3 “fifteen-minute” presentations (really more like [...]... Read more »

Methane!  Move over cow flatulence and burping, methane is leaking from under the Arctic in a big way.  Methane, that innocuous-seeming molecule with 4 hydrogens and a carbon, is actually a more potent greenhouse gas than the carbon dioxide molecule of greater fame–up to 25 times more potent actually.  However, atmospheric methane concentrations are much [...]...

Self-Knowledge - Emotional Intelligence For Personal Growth Part IV

by David Johnson, MSW, LICSW in Dare To Dream

This is the fourth in a series of articles on emotional intelligence for personal growth.

Self-knowledge is something we all strive towards. But how many of us have done a complete review of our emotions and how they influence our thoughts and behavior? Most people find that pretty hard to do, especially since they struggle to put their feelings into words. We talk about "will power" as the ultimate motivation. It might surprise you to find out that motivation is really emotion.

Obesity, more and more reports and resources!

by PhD Blogger in Exercise Psychology

There are it seems more reports and strategies concerning obesity than just about anything else. The strange thing is I have yet to read a bad strategy or poorly presented report, most of the papers are excellent. Its the scale and complexity of the problem that seems to be defeating us. The best report on the causes remain in my view the UK Government Foresight report, available on this site.  There is also the recently published Scottish report Preventing Overweight and Obesity in Sc........

Thymus Transplant Extends Life in Old Mice

by Reason in Fight Aging!

Amidst the preprint list of the Rejuvenation Research journal, I see an interesting paper I'd somehow missed: life span can be extended in old mice by transplant of a young thymus. Noninvasive Neonatal Thymus Graft into the Axillary Cavity Extends the Lifespan of Old Mice: Neonatal thymus grafts exert a rejuvenating action on various immunological and nonimmunological functions found altered in old mice. Commonly, half of a thymus is grafted under the kidney capsule. The invasiveness of the surg........ Read more »

Can going to church change your views of god?

by Tom Rees in Epiphenom

Christians don't agree on the nature of their god. Their different ideas are many and varied, but one broad way of looking at it is that they tend to believe either in a personal god (one who takes an active, day-to-day interest in people's lives and also intervenes), or an impersonal, distant god (the sort of god who lights the blue touch paper at the moment of creation and then retires to a safe distance).So who believes in what kind of god? Well, that's the topic of a recent paper by Scott Sc........ Read more »
