Degradation rates rise exponentially with temperature while an arithmetic mean adds linearly. Mean kinetic temperature is the weighting that reconciles the two, and it is…
What the placebo arms of the withdrawal trials actually tell us
The evidence on stopping is better than the evidence on almost anything else in this field, because somebody deliberately randomised it.
Falling ferritin is not always falling iron
A substantial proportion of the abnormal results generated during rapid weight loss are consequences of the weight loss rather than findings about the person.
Side effects, cost, supply, target: four reasons with four trajectories
Why the reason for stopping changes what happens afterwards.
D-amino acids are invisible to mass spectrometry, and that is the whole problem
What would be needed to catch each of these, and what it would cost.
Collapse temperature, and the hour of the cycle where shelf life is lost
The physics of the drying cycle explains why some cakes are matte and full-volume and others are glassy discs, and why the difference is not cosmetic.
What column temperature does to selectivity
Column chemistry, particle size and pore diameter determine what the separation is capable of before the gradient is even programmed.
A vial can be 99.4 per cent pure and not sterile in the same afternoon
Every certificate circulating in this market answers a question about molecules. Almost none answers a question about organisms, pyrogens, or the integrity of the seal.
The one-quarter rule, and the paper that took it apart
The gap between a defensible recommendation and a confident one is where most of the harm in this subject lives.
A guide to the results that will resolve themselves
