Are you the sort who grows wary around other people when flu season hits? You now have another tool in your (slightly anti-social) arsenal. The latest version of the Weather Channel app for Android and iOS now includes a Flu Insights feature that uses IBM's Watson to warn you when influenza is likely to be on the warpath. The team-up wields machine learning to provide a 15-day flu forecast as well notifications that pop up at key moments, such as the start of flu season or confirmed outbreaks. Ideally, this will keep you from going to a house party full of soon-to-be-sick virus carriers.
