Changes take energy – that’s nothing new, I know, but perhaps something as clinicians we might forget when we work with people who have chronic pain. I was thinking about this as I’ve had a week away from regular blogging so I could focus on writing and some self care. Things are busy and [...]... Read more »

There have been prior clues that creativity benefits from ample cross-talk between the brain hemispheres. For example, patients who've had a commissurotomy - the severing of the thick bundle of nerve fibres that joins the two hemispheres - show deficits on creative tasks. Now Elizabeth Shobe and colleagues have provided the first evidence that creativity is boosted by an intervention designed to increase hemispheric cross-talk.Shobe's team tested 62 participants on a version of the "Alternative ........

I decided to take a break from bacteria today and decided it might be fun to just choose something totally random to write about. Taking a daring leap into the unknown I decided not only to try and find out somthing about multicellular creatures, but about those multicellular creatures about which I know the least: amphibians.The above picture of an axelotl may have had something to do with my decision. Note the similarity to a pokemon that has accidently wandered into Star Wars.There are three ........ Read more »

The Dutch press is reporting a new study with an international perspective on what drives church attendance (the authors are Stijn Ruiter, senior researcher at the Netherlands Institute for the Study of Crime and Law Enforcement, and Frank van Tubergen, a professor of sociology in Utrecht).
What they set out to do was to compare the major theories on what causes religion, using data from the World Values Survey and other sources. Broadly speaking, you can summarize these theories like this:... Read more »

Besides being a delicacy in Japan and various other parts of the world, sea urchins have a longstanding career as a model organism in biology. The first description of these spiny, spineless creatures can be found in Aristotle’s History of Animals, dating from the 4th century BC 1. From the 1800s onward, the sea urchin [...]... Read more »

Some people have better genes than other people; such is the luck of the draw. The effects of most genetic differences on human longevity appear to be small in comparison to the effects produced by lifestyle choices, however. You are still the master of your own destiny in that regard. Time wasted in wishing you had a better variant of FOXO3A would be better spent exercising. A great deal of modern life science research is focused on deciphering the operation of our genes and metabolism. Along t........ Read more »

Just because Darwin wouldn’t discuss the origin of life in his work, doesn’t mean he didn’t have an opinion on the matter. And that opinion is actually pretty close to modern scientific thinking, that living things are products of chemistry rather than something requiring divine intervention. A recent paper cataloguing Darwin’s notes on the subject [...]... Read more »
Ask a bunch of expectant women what worries them about labor, and chances are many of them will say, “the pain.” Much is made about pain in labor. Women prepare for it, nurses constantly assess it, anesthesiology departments exist to eliminate it, and so on. But while there are many experiences of labor pain, just [...]... Read more »

A novel temporal illusion, in which the cause of an event is perceived to occur after the event itself, provides some insight into the brain mechanisms underlying conscious perception. The illusion, described in the journal Current Biology by a team of researchers from France, suggests that the unconscious representation of a visual object is processed for around one tenth of a second before it enters conscious awareness.

One of the most interesting (and most complicated) things about obesity is its very strong neural component. Now of course at its most basic level, body weight comes down to the balance of energy intake versus energy expenditure. Unfortunately, many aspects of this energy balance equation are outside the influence of conscious control. The brain is constantly sensing nutrients like glucose, and hormones like leptin and insulin in order to determine current energy stores, and using this inform........ Read more »

Ed has already given the lowdown on a new study in Nature which might lead to a rethink on earthquake hazards in the continental interior. Plate tectonics treats plates as entirely rigid entities, but continental crust is too weak, and too riddled with faults left over from when it was close to a plate boundary, for it to entirely hold up when subjected to the stresses of plate motion. So although a very large proportion of the Earth's earthquakes occur at plate boundaries, there is also some ........ Read more »

North American tall grass prairie holds an unfortunate distinction of having faced one of the highest conversion rates of any ecosystem in the world. In Manitoba, 99% of the historic tall grass prairie has been lost, mostly to agriculture.
So if 99% is gone, how is the remaining 1% making out?... Read more »

The search for eternal youth is as old as time itself. The theme of immortality winds its way through religion, mythology, poetry, fiction, and modern movies. Usually, stories of those who have achieved immortality expose the curse of eternal life, rather than the blessing of perpetual youth. While living forever may never be possible, life [...]...
