In the pop culture world of mainstream media, magic bullets are common. Every week there is a new miracle vegetable and then the following work there will be scare journalism about some chemical.

In the world of magic bullets, smoking causes lung cancer. Yet science knows that a risk factor is not genetic determinism. If lung cancer among non-smokers were itemized separately from smokers, it would be in the top 10 killers all on its own, and shockingly few smokers get lung cancer compared to the hundred million who are smoking just in America.

2.1 billion people, nearly 30% of the world's population, are overweight, according to a new analysis of data from 188 countries.

Cheap, plentiful food is a win for the world but now we have a major public health epidemic in both the developed and the developing world. 

A multi-institutional team of researchers has pinpointed exactly what goes wrong when chronic lymphocytic leukemia (CLL) patients develop resistance to ibrutinib, a highly effective, precisely targeted anti-cancer drug. In a correspondence published online May 28 in the New England Journal of Medicine, they show how the mutation triggers resistance. Their finding could guide development of new agents to treat drug-resistant disease.

Ibrutinib received accelerated approval from the Food and Drug Administration for use in chronic lymphocytic leukemia in February. It has revolutionized treatment, transforming CLL from a deadly disease to a chronic one. But about eight percent of patients develop resistance to this lifesaving drug.
