Video: Really Achieving Your Childhood Dreams

Many of you have no doubt already seen Carnegie Mellon computer scientist Randy Pausch's wildly popular 'last lecture', "Really Achieving Your Childhood Dreams". For those of you who haven't, watch it, seriously (it's embedded below, or click here. You can also download the lecture via iTunes). The back story, briefly, is that Pausch was diagnosed with pancreatic cancer in September 2006 and later given only a couple of months to live. He gave this lecture in September of 2007 and he died in July, 2008.

Call for Submissions: Carnival of the Africans #4

Dr. Spurt of Effortless Incitement, recently awoken from a deep bloggy-slumber, will host the next edition of the Carnival of the Africans on November 28th. If you're an African blogger or you've blogged on an African topic, gather up your best three or four posts from the last month and email the Doctor at doctor[dot]spurt{at}gmail[dot]com. (Also check out his call for submissions).

As I've said many times, participating in carnivals is an excellent way to promote your blog - it not only drives traffic directly, but also indirectly by increasing your Technorati authority. So get to it guys!

Encephalon #59

Welcome to the 59th edition of Encephalon, the blog carnival to read if you're at all into (vertebrate) brains...

First up is GrrlScientist, our next host and author of Living the Scientific Life, with a report on a fascinating study that combines refrigeration and neuroscience in songbirds. No, really.

Vaughn of the venerable Mind Hacks submitted a particularly interesting post highlighting a recent Cortex special issue (viewable here via Science Direct) on the neuropsychology of paranormal beliefs and experiences. I do hope that a lot more research like this gets done...

Next is posts by two of the Neuroanthropology authors, Greg and Daniel. The latter briefly discusses internet communities of delusional or psychotic individuals, while the former writes at length about a new paper by Michael Wheeler and Andy Clark on embodied cognition and cultural evolution.

Walter Jessen of Highlight Health reports on important developments in the genetics of autism: researchers have identified several SNPs likely partially responsible for the disease.

The mighty Neurocritic submitted a very interesting post on the finding that there isn't global cognitive decline in Huntington's Disease, on the contrary, certain cognitive functions might even be enhanced. Another very nice illustration that things are always more complicated than they seem...

Sandy Guatam of The Mouse Trap sketches the goals of personality psychology and the thinks-through the neurological correlates of poverty.

Nicky Penttila and Ben Mauk at the relatively new Dana Press Blog have worthy articles on the big business potential of neurotechnology and dancing for Parkinson's patients.

Finally, two posts from Sharp Brains: Dr. Joshua Steinerman polls readers on their feelings about cognitive mental status assessments and Alvaro updates us on physical fitness and brain fitness.

That's it! The next edition will be hosted by GrrlScientist on December 8th. If you would like to contribute, please send an email to encephalon{dot}host{at}gmail{dot}com.

Ignore this, I'm just helping out with my Google Juice...

Sylvia Browne

Light posting apology

Apologies for the recent lack of entries - I've been rather busy in the meatspace recently. There should, however, be some action over the next couple of days.

Malcolm Gladwell times two...

As I've said several times before, Malcolm Gladwell is my favorite science journalist. So I was happy to discover (via Mind Hacks) that New York Magazine has published a lengthy profile of Gladwell which focuses on his upcoming book Outliers.

Also, Gladwell has a new article, entitled "The Uses of Adversity", out in the New Yorker. As usual, fascinating and highly recommended.

Evolutionary Perspectives on War

New Scientist magazine has a report on a very interesting-looking recent University of Oregon conference entitled "Evolutionary Perspectives on War: An Interdisciplinary Conference" (pdf). I must say, I'm deeply sorry to have missed it - several of the papers presented looks fascinating:

• Steve Frost ("Evidence for coalitional aggression in the hominid fossil record"),
• Steven LeBlanc ("Recent hunter-gatherer warfare as a model for our evolutionary past"),
• Samuel Bowles ("Was Warfare among Ancestral Foragers Sufficiently Common to Affect the Course of Human Evolution?"),
• Joshua Duntley ("Evolutionary psychology of war"), and
• Napoleon Chagnon ("Human conflicts and warfare in history: An evolutionary assessment").
  

Some of the most interesting bits from the New Scientist piece:

Now a new theory is emerging that challenges the prevailing view that warfare is a product of human culture and thus a relatively recent phenomenon. For the first time, anthropologists, archaeologists, primatologists, psychologists and political scientists are approaching a consensus. Not only is war as ancient as humankind, they say, but it has played an integral role in our evolution.

The theory helps explain the evolution of familiar aspects of warlike behaviour such as gang warfare. And even suggests the cooperative skills we've had to develop to be effective warriors have turned into the modern ability to work towards a common goal.

...

If group violence has been around for a long time in human society then we ought to have evolved psychological adaptations to a warlike lifestyle. Several participants presented the strongest evidence yet that males - whose larger and more muscular bodies make them better suited for fighting - have evolved a tendency towards aggression outside the group but cooperation within it. "There is something ineluctably male about coalitional aggression - men bonding with men to engage in aggression against other men," says Rose McDermott, a political scientist at Stanford University in California.
