Egypt Week – Oxytocin and Ethnocentrism

by Jon Wilkins in Lost in Transcription

So, as we approach the end of Egypt Week, we are going to talk about recent paper in PNAS. The researchers examined the effects of oxytocin on the extent to which people exhibit in-group favoritism. They use ethnic markers to indicate in-group versus out-group membership. In this study, which was performed in the Netherlands, the in-group was Dutch and out-groups were German or Arab.

Here's the bottom line: subjects who were given oxytocin were more likely to favor in-group members relative to........ Read more »

Psycasm - It's like a blog in your ears

by Rift in Psycasm


So I've been a bit snowed under lately. As I mentioned recently, we've had some pretty big floods in my part of the world, and as a result all my summer semester workload has backed-up into one ugly pile of responsibility.And so my blogging has been a bit light on while I tackle these assignments and exams. Fear not, as soon as I get the chance I fully intend to look into what the litera; (read more)

Flooding and disease

by James Byrne in Disease Prone


I’m not sure what the coverage has been like overseas but most of the east coast of Australia has been hit pretty hard. First there were biggest floods Australia has seen for a VERY long time that started in Queensland and continue to affect the east cost of Australia. Then, instead of letting Queensland off the hook for a few weeks nature hit the coast with a cyclone THE SIZE OF THE U.S.A. that might move so far inland that it could dump rain into my state, which is a desert, halfway across ........

Hidden in plain sight: discovering cryptic vesper bats in the European biota

by Darren Naish in Tetrapod Zoology

In terms of its zoological diversity, Europe is the best known continent on the planet. Indeed it's generally assumed that just about all of Europe's macrofauna has, by now, been discovered. While that's mostly true, it seems that at least a few extremely similar species - so called 'cryptic species' - have been missed, mostly because they're extremely similar to their close relatives.





Here, I want to look briefly at new discoveries made concerning the diversity of European microbats [compo........ Read more »

Casual sex is not so bad after all

by Tom Rees in Epiphenom



Some women from Mars
A while ago I read a paper arguing that religion 'protected' teens against sex. It was your usual analysis - finding that religious teens are less likely to have sex outside of marriage - but the tacit presumption intrigued me. Is sex really that harmful?

Well, no one study is going to answer that, but here's one from Jesse Owen and colleagues at the University of Louisville helps shed some light on it.

Their study has the advantage over most in this field in that it's l........ Read more »

Touching Death

by Eric Michael Johnson in The Primate Diaries in Exile

The latest stop in the #PDEx tour is being hosted by The Prancing Papio:There is something intensely animal about our relationship with the dead. As an atheist I don’t feel particular reverence or awe at the site of a cadaver. It mostly just creeps me out. But even religious believers, those who should be comfortable with the idea that a dead body retains no trace of the person they once knew, also seem to have trouble letting go of what St. Paul called “confidence in the flesh.” In funera........

Early Complex Societies & Early Organized Religions

by Cris Campbell in Genealogy of Religion

Historians have long known that the shelf life of complex societies throughout human history has been rather limited. Archaeologists are aware of this also. But how to explain it?

Culturomics does not exist

by Bjørn Østman in Pleiotropy

'Culturomics' does not exist. As far as I'm concerned, if it isn't on Wikipedia, it doesn't exist. However, it is listed on Wikipedia's Word of the year for 2010 under the designation 'Least likely to succeed'. As an amusing side note, it also says this: Most Unnecessary: refudiate (Blend of refute and repudiate used by Sarah Palin on Twitter. The laughs.... Read more »

Adaptationism in the Human Penis

As Scicurious’ mom points out, penises are funny lookin’. As long as humans have been humans, men and women have looked down and thought, “now what could be the possible reason for that?” The question no doubt vexed our early ancestors so much that they simply had to evolve larger brains to think about it [...]...

Overweight Kids Are More Sensitive to Obesogenic Environment

by Arya M. Sharma in Dr. Sharma's Obesity Notes

One of the key misconceptions around the obesity epidemic is that obese kids have lifestyles that are so much worse than those of their non-obese peers.
This assumption, as noted in a recent post, was not really borne out by the findings in the Canadian Health Measures Survey, which did not find marked differences in physical [...]... Read more »
