In a nifty bit of reporting, veteran health reporters Shannon Brownlee and Jeanne Lenzer revealed in "Stealth Marketers," a story on Slate, that a "Prozac Nation: Revisited," a radio piece on antidepressants and suicide that ran on many public radio stations recently, "featured four prestigious…

I've been remiss in tracking here the farmed salmon issue I wrote about in the April/May Eating Well. Much has transpired; here a few tidbits and updates.
Soon after my feature ran, news broke that the Sacramento king (aka chinook) salmon run -- traditionally fairly robust, and the base of both…

That our brains account for 20 percent of our calorie use tends to amaze people, as it did me. Now it appears that about a third of that is devoted to brain maintenance rather than electrical signaling. The full dish here:

It seems that the rise in ER use comes not from the poor uninsured but from a much more affluent income sector.

Some great stuff I've come across, lack time to blog on, but would hate for you to miss:
In On being certain, neurologist and novelist Robert Burton, who writes a column at Slate Salon, looks at the science of what makes us feel certain about things -- even when we're dead wrong about them. His…

Suddenly it's salmon everywhere -- or in some cases, nowhere.
My story on "The Wild Salmon Debate: A Fresh Look at Whether Eating Farmed Salmon is ... Well ... OK," was published a couple weeks ago in Eating Well. You can see the Eating Well web version here or download a pdf here. The story…

The Kirsch study published a few weeks ago has stirred much discussion of the placebo power of antidepressants (or is it the antidepressant power of placebos?); it's clear that the act of taking a pill that you expect to help you often does help you.
But can the availability of a pill meant for…

This one's getting a lot of play: There are traceable levels of prescription drugs in many public water supplies.
The Times includes the AP story, which is both long and good. I bumped into it first on the Wall Street Journal Health Blog:

Why aren't your wages going up? Maybe because you're the one paying for the health insurance your boss is supposedly paying for.
That's the gist of a new commentary in JAMA, which I'd missed till the Health Blog at the Wall Street Journal brought it to my attention: "Who Really Pays for Health…

There's been a lot of attention the last couple years to the possibility of brain-based lie detector tests -- most of it premature. That coverage, I see now, has overlooked (as did I!) a 2005 study that showed compulsive liars are wired differently -- in an unexpected way -- than the rest of us.…

With so much written here lately about placebos and drug effectiveness, I would not want to leave out this remarkable study: Placebo effect is stronger, apparently, if you pay more for the placebo.
This is a fascinating study described in a letter to the Journal of the American Medical…

A quick heads-up: Nature weighs in on the flap over the Kirsch SSRI study that found antidepressants no more effective than placebo. I've given a lot of attention to the placebo issue. Nature stresses another point: That the Kirsch study underscores the need for clinical trial data to be public. At…

Now here's a match-up: the fine-grained, highly particularized, unpredictable, and insatiably curious mind of Nicholson Baker and the many-grained field of knowledge expressed in Wikipedia. In a great reading pleasure, Baker reviews John Broughton's Wikipedia: The Missing Manual in the current…

The ripples from the PLOS Medicine antidepressants-don't-work study by Kirsch et alia, which I covered below, just keep spreading. Those who want to follow it can do well by visiting or bookmarking this search I did (an ingenious Google News search for "Kirsch SSRI"). It seems to be tracking the…

The Kirsch study I wrote about a couple days ago, which found that antidepressants seem to have no more effect than placebo, has generated a wide variety of reactions in the blogosphere and press. Several things of note here:

[This is a revised, expanded version of the original heads-up I put up last night.]
A large new meta-analysis of SSRI antidepressant trials concludes that the drugs have essentially no therapeutic effect at all. The study, in PLOS Medicine today, comes on the heels of another study published a few…

I've not had time to thoroughly read this yet. But on the heels of another study published a few weeks ago (I blogged on it here) showing that SSRIs have little therapeutic effect if you include the (unflattering) clinical trials the industry had previously hidden, PLOS Medicine now publishes a…

Stumbled across this early this morning: Why the Mona Lisa's smile is so strangely alluring, and seems to come and go. From the website of Harvard neuroscientist Margaret LIvingstone:

A bit o' squabble has broken out about hopeful monsters. As paleontologist evolutionary geneticist Jerry Coyne notes in a guest post at The Loom, Carl Zimmer's blog, hopeful monsters are the products of ... well, there's the problem: They were either the product of sudden large evolutionary forces…
