Health risk associated with harmful substances in food may be underestimated

Mice are often used to test whether substances in food are harmful to humans. This requires that mice and humans metabolise substances in the same way. Humans have certain enzymes in more parts of the body than mice. The health risk associated with harmful substances in food may therefore be underestimated.

Heat, extreme exercise or febrile illness may also trigger MH

Malignant hyperthermia (MH) is a potentially life-threatening inherited disorder of muscle. Patients who are at risk for MH usually have no outward signs of muscle problems. However, when exposed to certain commonly used general anesthetics they may develop very high body temperature, increased heart rate and muscle breakdown. If not recognized and treated promptly MH may be fatal.

Do weight-loss incentive programs actually work?

Such experiments live at the nexus of cost-benefit analysis, behavioral psychology and the obesity crisis. The best programs are carefully calculated to exploit human nature: our love of a windfall, the risk of losing a small but significant financial stake, the camaraderie of a team effort, the heat of competition. All in the hope it may push us to do something difficult and unpleasant: shed pounds.
