22. Using the word "impossible" is the fairly predictable signature of a scientific poseur.

Mathematicians can justify occasionally speaking in terms of black and white. Scientists who do end up eating crow - very black crow.

This author is relying on the fact that cellphones do not create ionizing radiation as proof they don't cause cancer. Though his own research may provide evidence that contradicts the following, I suspect it's just carelessness.

"WHO: Cell phone use can increase possible cancer risk

(CNN) -- Radiation from cell phones can possibly cause cancer, according to the World Health Organization. The agency now lists mobile phone use in the same 'carcinogenic hazard' category as lead, engine exhaust and chloroform.

Before its announcement Tuesday, WHO had assured consumers that no adverse health effects had been established.

A team of 31 scientists from 14 countries, including the United States, made the decision after reviewing peer-reviewed studies on cell phone safety. The team found enough evidence to categorize personal exposure as 'possibly carcinogenic to humans.'"
