A novel area of circadian research is the influence of clock genes and circadian rhythms on the etiology of mood disorders. This area of research suggests a need for alternative therapeutic interventions, such as chronotherapy (using melatonin, bright light therapy, and adjusted sleep/wake schedules),that do not risk addiction by pharmacological treatments. ...

I am getting towards the end of my discussion of Philip McCann’s paper, “Economic geography, globalisation and New Zealand’s productivity paradox” .

Most of what we know about prehistoric North American atlatls comes from the many well-preserved examples found by Alfred Kidder and Samuel Guernsey in the early twentieth century in Basketmaker II rockshelters near Kayenta, Arizona. We know much more about atlatl use in Mesoamerica, where the atlatl was still widely used in the contact era, [...]... Read more »

Why are large-scale structured databases and meta-analyses important to advance the field of human brain mapping? One reason is that individual functional magnetic resonance imaging (fMRI) studies can be notoriously unreliable and underpowered (Bennett & Miller, 2010; Fliessbach et al., 2010; Kriegeskorte et al., 2009; Vul et al., 2009).

Bar-tailed Godwits / Image: Phil Battley Recent studies using satellite telemetry or geolocators have shown that some bird species are capable of very long nonstop flight during migration, far longer than previously thought. Some of the longest belong to Bar-tailed Godwits, which have been tracked performing nonstop flights of over 11,000 km (or about 7,000 miles). Ruddy Turnstones perform similarly impressive flights. A new study in PLoS Biology tries to measure whether there are any limits to ........ Read more »

The plagues of the Dark Ages are often considered to be one of the worst epidemics humans ever faced. With no sanitary practices, germ theory, or scientific medicine to speak of, the diseases were unstoppable and the patients’ survival depended solely on their luck and the strength of their immune systems. Today, we’re better off [...]... Read more »

Prohaska and Gailey (2010) refer to the practice of men who seek 'out women they [those men] perceive as fat or unattractive for sport or sexual gratification’ as 'hogging' (p.13). The big ticket issue, therefore, pivots between men who hate women absolutely and men who love other men for all the wrong reasons. In short, misogyny and homosociality.

Among the great American exports to the rest of the world, there are a bewildering variety of religious cults and sects. Not all have take root, but the most successful - groups like the Mormons, the Jehovah’s Witnesses, and the Seventh Day Adventists - now number in the millions.
Their success is mostly down to prosyletisation, in addition to any endogenous growth (due to fertility) that was the topic of the previous post.
So why are they so successful, and perhaps more importantly where ar........ Read more »

Evolution has resulted in a remarkable array of reproductive strategies in the animal kingdom. After all, if one is unsuccessful in passing on one’s genetic blueprints there was really not much point in being alive in the first place. Several invertebrate organisms employ a ‘polyandrous’ sexual system, wherein a female mates with several males. It [...]... Read more »

Runners Cramp - Calves cramping - it's AWFUL. In talking with folks who run in VFF's it seems that one usual side effect initially at least is that, when picking up the pace in VFF's (perhaps especially up hill), calves may start to cramp up. Guaranteed, if we keep going with this run, once that cramp starts, the calf or calves will turn to unyielding, painful rock. What can be surprising is ... Read more »

SUBJECTIVE experience poses a major problem for neuroscientists and philosphers alike, and the relationship between them and brain function is particularly puzzling. How can I know that my perception of the colour red is the same as yours, when my experience of the colour occupies a private mental world to which nobody else has access? How is the sensory information from an object transformed into an experience that enters conscious awareness? The neural mechanisms involved are like a black box,........ Read more »
