Teeth as a forensic clock
Here’s something we’re likely to see that endearing techno whiz kid, Abby Sciuto, whip out of her forensic arsenal next season on NCIS. They’re chemical and nuclear technologies to date teeth. When paired up, new research indicates, they’ll identify not only when people were born but also the age at which they clocked out — thereby pointing to the general date of death.

Interphone study finds hints of brain cancer risk in heavy cell-phone users
A major decade-long international study concludes that, overall, cell-phone users show no increased risk of developing brain tumors. The same study reports that among people who have used cell phones the most and longest — for at least 10 years and on average 30 minutes or more a day — risk of brain tumors is substantially elevated when compared to people who don’t use cell phones. And the real enigma: Tumor risks calculated for each of the lower cell-phone use categories was substantially under that seen in people who use regular, corded phones.

Interphone’s data on cell phones and cancer: The spin begins
A May 16 press release by the cell phone industry reports that “The International Journal of Epidemiology today published a combined data analysis from a multi national population-based case-control study of glioma and meningioma, the most common types of brain tumour.” In fact, the journal hasn’t. Yet. But the industry group was anxious to put its spin on the paper’s findings after a handful of UK newspapers reported on this study – well in advance of the scheduled lifting of a news embargo on its data.
