PHOENIX (AP) — The Arizona Department of Transportation is studying use of remote technology to help manage highway traffic that needs to merge when approaching a highway work zone involving at least one lane closure. ADOT says it has set up a “smart work zone" with a remotely controlled system using computers, portable message boards and sensors to provide drivers with real-time instructions based on changing circumstances. The study is being conducted at two bridge rehabilitation sites on Interstate 40 between Flagstaff and Winslow in northern Arizona. The remote system directs westbound traffic to merge into one lane well ahead...

How to Listen to the Background Hum of Gravitational Waves From all the Black Holes Colliding into Each Other Article written: 18 Apr , 2018 by Matt Williams The first-ever detection of gravitational waves (which took place in September of 2015) triggered a revolution in astronomy. Not only did this event confirm a theory predicted by Einstein’s Theory of General Relativity a century before, it also ushered in a new era where the mergers of distant black holes, supernovae, and neutron stars could be studied by examining their resulting waves.In addition, scientists have theorized that black hole mergers could actually...

A startling collision in an ancient galaxy slews Earth's largest telescopes to a spot in the Hydra constellation. Two rapidly spinning neutron stars have violently merged to form a possible black hole. And, for the first time, astronomers see its electromagnetic flash and hear its gravitational thunder as they watch new elements being born.

More Gravitational Wave Rumors: Colliding Black Holes? By Ian O'Neill, Discovery News February 9, 2016 08:15am ET MORE This computer simulation shows the production of gravitational waves during a black hole collision.Credit: MPI for Gravitational Physics/W.Benger-Zib More gravitational wave discovery rumors are flying, but this time they've taken a specific -- and, possibly, really exciting -- new twist. And what's more, we should find out whether the astrophysical rumor mill is correct or not by the end of this week; a National Science Foundation press announcement is planned for 10:30 a.m. ET on Thursday (Feb. 11), billed as an opportunity...
