Anyone who has read Chapter 13 of my book knows that I have a hobby-horse: the accuracy of metabolic rate measurement, especially in the metabolic phenotyping systems that are so widely used in the biomedical field. Now I've taken steps to make some of my (and others'!) misgivings known.
It's really frustrating to watch otherwise capable researchers in the biomedical field flock to use the same black-box metabolic screening systems that others used before because, well, everyone uses them.
