A study of the health effects of alcohol separates the population by a genetic difference: the ability to metabolize alcohol. Researchers found no benefit to drinking, moderate or not. Is it true? Maybe if you're Chinese.
Is there a magical prescription for how much exercise and activity eliminates the increased risk of premature death, which comes from sedentary behavior? A new paper takes a swing at an elusive target. Spoiler alert: This is an area that continues to defy precision.
Disease surveillance remains one of the highest-stakes areas of science. Careful consideration for unique circumstances underlying outbreaks, and more responsible collection of data, could save thousands of lives.
Dr. Edward Archer believes that nutrition science is not just misguided but actually harmful. That's an extraordinary statement that requires extraordinary evidence. Does he provide it in his latest paper?
Three pigs tested positive for antibodies to the Ebola virus, suggesting that these farm animals could serve as a host for the disease. Virus hunters should take note.

New research into the 1918 and 2009 influenza pandemics reveal a potential warning sign: Mild cases of influenza that occur in the spring or summer may be a harbinger of a devastating pandemic to come in the autumn.
There is an interaction between measuring and what is measured. Heisenberg's Uncertainty Principle is true for medicine and helps explain some confusing and changing health information. 
An infectious virus or idea plus a susceptible population can cause the flu, a riot or fake news. A study of the 2005 riots in France finds an epidemiologic explanation.  
In a 1965 address, epidemiologist Austin Bradford Hill introduced nine criteria that researchers should consider before declaring that A causes B. Here's a concise summary of his presentation.
Isn't it odd that Florida has so many people living with Alzheimer's? If Erin Brockovich was investigating the case, she probably would conclude that it's something to do with the water.
