Carmakers Take to the (Self-Driving) Test Track

Researchers from academia and industry took rides in experimental cars at a public test-track event in Teesdorf, Austria, last week, but the main draw may have been the other attendees.

Now they are attracting academic study and government research dollars. Continue reading Taxonomy Goes Digital: Getting a Handle on Social Bots

Other workers swing machetes at overhanging tree branches. Along the cleared shoulder of the road, another crew tightens a cable on a freshly planted utility pole.
