Should the Human Microbiome Be Considered When Developing Vaccines?

The human microbiome, especially in the intestinal tract has received increased attention in the past few years due to its importance in numerous biological processes. Recent advances in DNA sequencing technology and analysis now allow us to better determine global differences in the composition of the gut microbial population, and ask questions about its role in health and disease. Thus far, r...

When Should Potentially False Research Findings Be Considered Acceptable?

Ioannidis estimated that most published research findings are false, but he did not indicate when, if at all, potentially false research results may be considered as acceptable to society. We combined our two previously published models to calculate the probability above which research findings may become acceptable. A new model indicates that the probability above which research results should...
