Here is a recap of the stories that appeared last week at Science-Based Medicine, a multi-author skeptical blog that separates the science from the woo in medicine.  

A truly homeopathic defense of homeopathy (David Gorski) A review article by Iris Bell attempts to defend homeopathy and show how it might work through nanoparticles. The research she cites is a joke, and her reasoning is a meaningless word salad.  

Storytelling in Medicine (Harriet Hall) Anecdotal evidence is unreliable, but patient stories have a role in medical education. Putting a face to a diagnosis serves as a memory aid and a hook to hang the rest of our knowledge on. A book by Paul Griner illuminates important issues in medicine by relating stories from his decades of practice.  

Brain-Machine Interface (Steven Novella) There are exciting developments in the emerging field of brain-machine interfaces. Scalp electrodes or electrodes implanted in the brain have allowed patients to control a robotic arm by their thoughts. We can expect real-world applications as this technology is refined.  

Bodytalk: Medical theater (Scott Gavura) TED HQ has advised Tedx organizers to vet prospective speakers to ensure content grounded in evidence. They provide guidelines to recognize bad science and pseudoscience. Bodytalk is an energy-healing practice that is a good example of pseudoscientific health theater, appearing to do something but not accomplishing anything substantive.  

Fever Phobia (Clay Jones) Parents are overly concerned about the level of fever in sick children. They fear seizures and brain damage, and feel obligated to treat fevers with antipyretics. Fever is a sign of disease; but the fever itself is harmless and treatment should be based on patient comfort, not on thermometer readings.
