In 2009 the Large Hadron Collider (LHC), a giant particle accelerator near Geneva run by CERN, was preparing to restart after upgrades.

However, some members of the public expressed fear that the machine could produce catastrophic effects, including miniature black holes or other unknown dangers.

Google plans to release a redesigned Fitbit app this fall that reorganizes the interface into three main tabs: "Today," "Coach," and "You."
