XMRV Chronic Fatigue Syndrome Update
Sometimes science works the way it’s supposed to. Scientists make hypotheses, test them by gathering preliminary evidence, and then argue about the inevitable conflicting results. Eventually better and better evidence is gathered until a consensus is achieved. Actually, I think that is how science usually works, it’s just that most questions in science are narrow and technical and don’t command media or...
The Sweetener Wars – HFCS Strikes Back
The health conscious and trendy public are a bit obsessed with the food they consume. This can be a good thing, to the extent that it results in a more healthful diet, but unfortunately those interested in improving their diet must wade through a great deal of misinformation before getting to accurate and helpful information.

An Acupuncture Meta-Analysis
A recent meta-analysis of acupuncture studies for chronic pain by Vickers et al is getting a great deal of press. The authors’ conclusions are: Acupuncture is effective for the treatment of chronic pain and is therefore a reasonable referral option. Significant differences between true and sham acupuncture indicate that acupuncture is more than a placebo. However, these differences are relatively modest, suggesting...

There are several reasons that consumers might prefer organic produce, including the belief that organic...
The Power of Replication – Bems Psi Research
I love reading quotes by the likes of Karl Popper in the scientific literature.

Homeopathy’s Recent Woes
Be careful what you wish for. In the last few decades purveyors of dubious medical treatments and products have been trying to go mainstream, and they have had some unfortunate success. They asked for serious scientific investigation into their claims – and they got it. They asked to be treated like real medicine (but not really, they only want the trappings of...
Eggs and Atherosclerosis
The headline of a recent Los Angeles Times article is, “No yolk: eating the whole egg as dangerous as smoking?” The question mark is meant to convey uncertainty or surprise, or perhaps both. The article represents much of what is wrong with science and health reporting by mainstream media. The news report is based upon an article published in Atherosclerosis – Egg...
Are Berries the New Snake Oil?
Are berries a superfood? No, they're just good for you, like all fruit.
Antifluoridation Bad Science
A new review of research out of Harvard University suggests fluoridating drinking water above the EPA limit is a bad idea - which we already knew.
