Yes, obesity is a serious disease but it must also be taken seriously

“Not Everything That Is Faced Can Be Changed, but Nothing Can Be Changed Until It Is Faced”: A Response to Recent Commentaries

If it is methylated it must be Tectonic.

The molecular mechanisms by which organisms defend themselves against predators and the molecular weapons the predators use to attack their victims have coevolved over eons of time. Microbial pathogens share the common feature of being covered in a surface coat comprised of carbohydrates (glycans) linked to lipids and proteins or as free polysaccharides. In vertebrates, such defense mechanisms ...

Healthy communities must also be sustainable communities.

The author contends that healthy communities must be both environmentally and socially sustainable, given that health depends on the quality of the built and natural environments, and that global change resulting from the industrial economy is affecting the web of life. He argues that suburban sprawl wastes scarce resources and disproportionately places those resources in the hands of suburban ...

Why the Transitivity of Perceptual Simultaneity Should be Taken Seriously

A relation is transitive if and only if from the fact that A has a relation to B, and B has a relation C, it necessarily follows that A also has a relation to C. As a relation fulfilling this requirement, consider simultaneity understood as two events occurring at the same time and only at the same time (thus this is not a case of mere partial temporal overlap): If A and B share all the same te...

Quasiregular Singularities Taken Seriously

I discuss a special class of singularities obtained as a natural 4-dimensional generalization of the conical singularity. Such singularities (called quasiregular) are ruinous for the predictive force of general relativity, so one often assumes (implicitly as a rule) that they can be somehow excluded from the theory. In fact, however, attempts to do so (without forbidding the singularities by fi...
