The information Lau and colleagues presented in the February edition was timely and raised concerns about the Tendril lead. With further analysis, it appears the external disruption in the insulation is unlikely to be of major concern going forward, and the problem was most likely due to an external abrasion.

As with science in general, new information and careful inspection of new observations can take a while to digest. Sometimes concerns are unfounded, but require a more in depth analysis to know for sure. While Lau and colleagues raised serious concerns about the lead, with new information provided by Mark Carlson, it appears that we were not looking at the tip of a new iceberg.
