A nice short piece on "The Prehistory of Stress" by Matt Ford at Ars Technica (newly designed site worth checking out).
I have heard people say, on multiple occasions, that they think stress is a modern, Western phenomenon. While the psychological phenomenon known as stress has only had a formal name for just over 80 years, knowing when it was first suffered by our ancestors is a daunting task. Was life really better in the past? Is stress an entirely modern phenomenon?
Using modern forensic technology and a decidedly modern understanding of biochemistry, researchers from The University of…

Dear Readers, here's your chance to weigh in:
Over at the Atlantic, David Shenk, a sharp writer who keeps a blog there called "The Genius in Us All," has posted a gentlemanly smackdown ("Metaphor fight! Shenk and Dobbs square off") that he and I had via email last week regarding the "orchid-dandelion" metaphor I used in my recent Atlantic piece, "Orchid Children" (online version title: "The Science of Success"). Every metaphor has its limits, and David Shenk, a highly capable writer, recognizes that well. Yet he thinks this orchid-dandelion metaphor is fatally flawed, at least as I use it…

I'm happy to announce that Houghton Mifflin Harcourt, publisher of many a fine book over the decades, will be publishing "The Orchid and the Dandelion" (working title), in which I'll explore further the emerging "orchid-dandelion hypothesis" I wrote about in my recent Atlantic story. (In brief, that hypothesis -- a simple but deeply transformative amendment of current views -- hoids that many 'risk genes' for behavior and mental problems magnify not just maladaptive responses to bad environments but advantageous responses to good environments. That is, these "risk genes" confer not just…

Ben Cardin, a Maryland Democrat, has asked the Pentagon for info on how many troops in war zones have been prescribed antidepressants while they were deployed. Cardin sent a letter Tuesday to US Department of Defense Secretary Robert Gates expressing concern about how antidepressants are being administered troops in Iraq and Afghanistan.
Cardin wants to determine if the Defense Department is prescribing antidepressants appropriately and is concerned about any connection between the meds and suicide rates among troops. In October, for instance, 16 active-duty US soldiers killed themselves,…

Hardly a day passes without yet another breathless declaration in the popular press about the relevance of neuroscientific findings to everyday life. The articles are usually accompanied by a picture of a brain scan in pixel-busting Technicolor and are frequently connected to references to new disciplines with the prefix "neuro-". Neuro-jurisprudence, neuro-economics, neuro-aesthetics, neuro-theology are encroaching on what was previously the preserve of the humanities. Even philosophers - who should know better, being trained one hopes, in scepticism - have entered the field with the…

By way of demonstration, the group plugged in stats from the Oct. 11 playoff game between the Angels and the Red Sox:
BOSTON -- Things looked bleak for the Angels when they trailed by two runs in the ninth inning, but Los Angeles recovered thanks to a key single from Vladimir Guerrero to pull out a 7-6 victory over the Boston Red Sox at Fenway Park on Sunday.
Guerrero drove in two Angels runners. He went 2-4 at the plate.

Just heard of a neat article about why feeling stupid on a regular basis is actually a good sign if you're doing serious scientific research. The article is by a fellow named Martin Schwartz, a professor of microbiology and biomedical engineering at the University of Virginia, and it was published in April of 2008 in The Journal of Cell Science. Here's an excerpt:
Productive stupidity means being ignorant by choice. Focusing on important questions puts us in the awkward position of being ignorant. One of the beautiful things about science is that it allows us to bumble along, getting it…
ddobbs | October 5, 2009Ruth may or may not have called his. But former player and Mariners announcer Mike Blowers, asked before the game for his prediction of the game, predicted a rookie player would hit a homer -- his first in the bigs -- into the second deck in left-center in his second at-bat on a 3-1 fastball. Man did it.
ddobbs | October 2, 2009Been a while, so these cover a span of reading.
I'm in the midst of my friend Adrienne Mayor's The Poison King: The Life and Legend of Mithradates, Rome's Deadliest Enemy, and can report that Mr. M is quite a poisonous but complicated handful -- a dark and deadly echo of his hero and model, Alexander -- and this reconstruction a splendid read.
A few weeks ago I finished Thomas Ricks' The Gamble, an excellent account of the surge in Iraq. Ricks -- who earlier wrote Fiasco, a devastating indictment of the run-up to the war, makes three things quite clear:
The surge was not about more soldiers…

Over at Gene Expression, Razib casts a skeptical eye on a study of the neuroanatomical variability of religiosity.
The brain areas identified in this and the parallel fMRI studies are not unique to processing religion [the study states], but play major roles in social cognition. This implies that religious beliefs and behavior emerged not as sui generis evolutionary adaptations, but as an extension (some would say "by product") of social cognition and behavior.
May be something to that, Razib says â but it would be nice "get in on the game of normal human…

ddobbs | September 11, 2009The ever-valuable Neuroskeptic, channeling Stanley Kowalski ("I knew a girl once said she was the glamorous type. She said to me, 'I am the glamourous type.' I said, 'So what?'"), asks just WTH it means to show that brain scans of earthquake survivors show that "trauma alters brain function."
The authors link their findings to previous work with frankly vague statements such as "The increased regional activity and reduced functional connectivity in frontolimbic and striatal regions occurred in areas known to be important for emotion processing". But anatomically speaking, most of the brain…

Henry could find the biscuit by sniffing the cups or knocking them over. But Hare does not plan to let him have it so easy. Instead, he simply points at the cup on the right. Henry looks at Hare's hand and follows the pointed finger. Kivell then releases the leash, and Henry walks over to the cup that Hare is pointing to. Hare lifts it to reveal the biscuit reward.

ddobbs | September 9, 2009For research she's doing about public attitudes on genetics and mental health, science writer Virginia Hughes is trying to get people to take a very short survey (I just took it; takes about 30 seconds) on that subject. Do mental health issues rise from genes, environment, or both? Would you get a child tested for a gene said to confer a certain level of risk for, say, autism? Questions like that. She'll use the results to inform her writing and her participation in a panel on ethical questions about the genomics of psych conditions at an upcoming conference at Cold Spring Harbor.
