Statistics, a weak link in environmental, medical, & toxicological studies?

Statistics are used throughout science both by those proposing a conclusion and those opposed to said conclusion. Statistics form the basis for a wide variety of claims made about environmental, medical, and toxicological matters. I would even go so far as to note that they are often utilized by charlatans...

Another estrogenic substance is identified (BPS, which is related to BPA), and the vector exposes nearly everyone
