Japanese dairy farmers are getting robots to milk their cows, as a labor crunch forces businesses to step up capital spending on robotics and information technology.

Health officials identified the avian influenza case in a Michigan dairy farm worker. This is the second time a person working with dairy cows has developed the virus.

The H5N1 virus is now infecting humans, with many field reports of human illness on dairy farms and three documented cases in people, including one with respiratory symptoms.
