Peter Lipson reported Monday about new research suggesting that Multiple Sclerosis may be caused by venous blockage. He correctly characterized some of the hype surrounding this story as “irrational exuberance.”
This is a phenomenon all too common in the media – taking the preliminary research of an individual or group (always presented as a maverick) and declaring it a “stunning breakthrough,” combined with the ubiquitous personal anecdote of someone “saved” by the new treatment.
The medical community, meanwhile, responds with appropriate caution and healthy skepticism. Looks interesting – let’s see some more research. There is a reason for such a response from experts – experience. Read more »

Many parents of children with autism have expressed to me their dismay that the anti-vaccine lobby is sucking all the oxygen out of the room for autism awareness. They feel that just being a parent of a child with autism makes others assume that they are anti-vaccine. They also worry that resources and attention are being diverted from promising legitimate research because of all the attention being paid to the failed vaccine hypothesis.
So it is good to occasionally focus on mainstream autism research to show that progress is being made, despite the unfortunate anti-vaccine sideshow. Read more »

I don’t know. The mainstream media is doing a wonderful job sensationalizing this case, presenting it without skepticism. Some outlets are doing a good job of discussing the relevant issues – but they don’t have the information to have a meaningful discussion of this particular case. Details are tantalizing but thin.
The case is that of Rom Houben. The story was broke, as far as I can tell, by the Mail Online – yes, that is a huge red flag. It does not make the story wrong, it just doesn’t instill in me confidence in the reporting.
Mr. Houben was in a terrible motor vehicle accident 23 years ago and has been paralyzed ever since. His diagnosis has been PVS – persistent vegetative state. However, recently, we are told, his mother insisted on a neurological re-evaluation. This is actually quite reasonable, generally speaking (again, without knowing specific details of this case).

Homeopathy, as a cultural phenomenon, remains an enigma. In the two centuries since its invention it has failed to garner significant scientific support. In fact, developments in physics, chemistry, biology, and medicine have shown the underlying concepts of homeopathy to be wrong – guesswork and speculation that lept in the wrong direction.
It turns out, like does not cure like. This is nothing more than sympathetic magic – popular at the time but now considered nothing more than superstition without any scientific basis.
It also turns out that diluting a substance does not make it more potent – this nonsensical idea (ridiculed even in the 19th century) violates the laws of thermodynamics, and the chemical principle of mass action. This is especially true when you dilute a substance beyond the point where chance would have even a single molecule of active ingredient left behind. The background noise of chemicals in homeopathic water is orders of magnitude greater than the signal of whatever had previously been diluted in it. Read more »

Charlene Werner is getting a lot of attention she probably did not anticipate or desire. She is the star of a YouTube video in which she explains the scientific basis of homeopathy. Before you watch it, make sure you are sitting down, relax, and brace yourself for an onslaught of profound scientific illiteracy combined with stunning arrogance. For those with more delicate constitutions I will give you the quick summary:
Einstein taught us that energy equals matter and light, but because matter can be condensed down to a very small space if you remove all the empty space between the elementary particles (I am paraphrasing to make her statements minimally coherent), we can mostly ignore matter. Therefore energy is light, and we are all made of energy – not matter (or at least so little matter, you can ignore it). Read more »
