Many Children Still Haven't Recovered from Katrina

by Child Psych in Child Psych

Now, five years later, there's new evidence of the significant, negative impact of Hurricane Katrina on children's mental health. The study "Children as Bellwethers of Recovery" was conducted by researchers from the National Center for Disaster Preparedness at Columbia University's Mailman School of Public Health and was published online by the Journal of Disaster Medicine and Public Health Preparedness.

The results come from a longitudinal study of 1079 families in Louisiana and Mississippi ........ Read more »

Will finding sex partners online make you sick?

by PalMD in White Coat Underground

(Comments are still down, and will be for the next day or two.  Sorry. We will try moving the discussion to the WCU facebook page. –PalMD) To people who grew up before the internet, the debate about whether Craigslist should be allowed to post “erotic services” must seem bizarre.  But meeting people online, whether for [...]...

What makes movement seem “artificial”?

Originally posted on Cognitive Daily. This is a guest post by David Kerns, one of Greta’s top student writers for Spring 2007. As movie special effects technology improves, more and more live-action shots are being replaced with computer animation.

No turning back for science

by Zen Faulkes in NeuroDojo

An article with a title like “Science’s dead end” seems like an active effort to troll the science blogosphere. Maybe author James Le Fanu has a point, but a quick search raise doubts as fast as you can type. He’s trained as a medical doctor, not a researcher. And he seems to be a cynical one, having written a piece with a similarly apocalyptic title, “The fall of medicine,” for the same magazine over ten years ago.

He outsider’s perspective is apparent in his first paragraph.

About Those Effigy Vessels

by teofilo in Gambler's House

Okay, I said I would say more about George Pepper’s description of the effigy vessels from Chaco, so here goes.  One interesting thing that he notes is that these are the northernmost examples of human effigy vessels found in the Southwest.  I believe this is still the case over a hundred years later; in general, [...]...

Maslow’s motivational hierarchy revisited

by sandygautam in The Mouse Trap

Image via Wikipedia I’ve written previously about Maslow’s motivational hierarchy and how that relates to the eight stage evo-devo model. Most people are familiar with the 5 motivational basic needs/motives theory of Maslow, but are not aware that he had later revised it to include eight basic needs/ motives.

2 legs good, 4 legs better: Uner Tan Syndrome, part 2

by gregdowney in Neuroanthropology

Beginning in 2005, reports by Prof. Üner Tan of Cukurova University in Turkey alerted the world to a number of families in which some members walked quadrupedally. This is the second part of a (so far) two-part post on Uner Tan Syndrome. Although you’re welcome to read the first part, I’ll give you the one sentence summary if you just want to push on and a piece of video clip on the cases.

The sex lives of yeast: Evidence for honest signaling

by Graves in Down the Cellar

Saccharomyces cerevisiae, the yeast used in baking bread and brewing beer, has a long history as a useful eukaryotic model organism. Yeast reproduce by budding, but sometimes haploid cells sexually reproduce by secreting pheromones and fusing into one diploid cell, which can then undergo meiosis to create four spores. Lately, this facultative sexual reproduction has been targeted by evolutionary ... Read more »

Flaming the debate

by Ted MacRae in Beetles in the Bush

As my interest in prairie insects has increased over the past few years, so has my interest in their conservation. Many insects are restricted to prairies through dependence upon prairie plants or their unique physical and trophic characteristics. Thus, preservation of not only prairie plants but their insect associates as well is a major goal [...]... Read more »

Boys Who Suicide and Masculinity Mutations

Normal? You're Weird - Psychiatrists

by Neuroskeptic in Neuroskeptic

Almost everyone is pretty screwed up. That's not my opinion, that's official - according to a new paper in the latest British Journal of Psychiatry.Make sure you're sitting down for this. No less than 48% of the population have "personality difficulties", 21% have a full blown "personality disorder", and 7% have it even worse with "complex" or "severe" personality disorders.That's quite a lot of people. Indeed it only leaves an elite 22.5% with no personality disturbances whatsoever. You're as l........ Read more »

the original Whorf

by Chris in The Lousy Linguist

Guy Deutcher's NYT's article on how language affects thought continues to get buzz, as surely his book Through The Language Glass will when people read it (it was just released 3 days ago and is currently #234 on Amazon's book rank). One common reaction amongst bloggers is that Deutscher gives Whorf himself unfairly harsh treatment, and ultimately mis-represents Whorf's own opinions.For example, Kathryn Woolard, SLA President, says "Whorf’s own statements of his theory look little like the car........

Problems with Pitch: Congenital Amusia and Tone Languages

by Sarah in Curious!

What, exactly, is tone deafness? We've all known someone who claimed he or she was tone deaf or "couldn't carry a tune." However, congenital amusia, which seems to be true "deafness" to tone, affects only about 4% of the general population - that is, 4% of the almost exclusively Western populations that have been studied.
Congenital amusia is one of several different types of music perception impairments. A person with the disorder is born with a variety of symptoms, including an inability to re........ Read more »

Hey Gilbert Lewis: Has life evolved a use for deuterium? Or does it just tolerate it?

by Steve Koch in Steve Koch Research

Andy Maloney in our lab has been studying solvent (water) isotope effects on kinesin and microtubules in the gliding motility assay.  He has data showing a speed slow down from both heavy-hydrogen water (D2O; deuterium oxide) and heavy-oxygen water (H218O; oxygen-18 water). The preliminary results are very exciting to me, because I think varying the water isotopes may be a useful new knob for studying kinesin, molecular motors, and other biomolecular systems such as protein-DNA complexes. ........

Investigating Metformin's Mechanisms

by Reason in Fight Aging!

Metformin is one of the known calorie restriction mimetics amongst drugs presently in use by the medical establishment. A calorie restriction mimetic is a drug that can reproduce some of the beneficial changes to metabolism exhibited during the practice of calorie restriction, which hopefully in turn leads to improved health and extended healthy life span. Metformin has been shown to modestly increase maximum life span in mice, though by much less than is possible through calorie restriction: ch........ Read more »

Open letter to anti-vaccinationists

Some people have commented to me in person (and online) that I was a little brash in calling those violently opposed vaccinations as evil or ignorant. Also, that I might be completely shutting off dialogue and having people immediately list me as one of those pro-vaccination whores. I thought about this for a long time [...]... Read more »
