Norwegians offer theory for risks of football heading
By Wayne Forrest
Researchers from Norway are offering a theory for a puzzling question on the risks of heading a football -- why does the practice seem to affect female players more than their male counterparts? They believe the phenomenon could be related to the size and weight of the ball relative to player size.

Fukushima study sheds light on childhood thyroid cancer
By Philip Ward
The latest results of mass ultrasound screening of children for thyroid cancer after the Fukushima disaster were published online on 29 November by JAMA Otolaryngology. The study provides vital data on thyroid cancer, but may lead to more demands outside of Japan for ultrasound scans in younger people, increasing the risk of overdiagnosis.

7T MRI may release mercury from amalgam dental fillings
By Wayne Forrest
MR imaging at 7-tesla magnet strength may release toxic mercury from amalgam dental fillings, according to a new study published online on 26 June in the journal Radiology. However, the effect was not found with the lower-strength 1.5-tesla magnets that are more commonly used in the clinical setting, the researchers noted.
