Scientists, Students in Prescott, Arizona, Help LIGO Detect Gravitational Waves

This year’s Nobel Prize in Physics was awarded to three men, but the detection of gravitational waves was the work of a thousand scientists and students — 10 of them from Embry-Riddle Aeronautical University in Prescott.

Worth Doing Right: How Climate Change Could Throw a Wrench Into Road repairs

Repairing with the wrong materials for shifting climates could be a road to nowhere, like this spot in the Suffolk village of Covehithe. Picture by Timothyansell123.

The American Society of Civil Engineers has given America’s roads a D rating. But a recent study shows that trying to raise that grade without accounting for climate change could put the country’s roadways at risk.

Mantle Mystery Yields to Diamond Vise

Improved imaging of the Earth’s interior has unlocked new subsurface mysteries, including an area 600 miles (1,000 kilometers) down where the mantle’s usual flow pattern changes.

Now, at a lab bench on the planet’s surface, a team of researchers might have found the reason why.

We’re Not in Phoenix Anymore: How Radio Signals “Skipped” All the Way to Kansas

Yes, it’s that exciting.

Unlike AM signals, FM is confined to line-of-sight, so Phoenix’s KBAQ radio station doesn’t typically reach much beyond the Valley of the Sun, let alone to a Volkswagen Beetle 875 miles away. So it’s no wonder that Ken Baker of the Radio Kansas Network was surprised to see what resolved on his HD tuner that day.

Air Conditioners Cool House by Heating City

Parents tell their kids, “Shut the front door, I’m not paying to cool the entire neighborhood.”

But research shows that, during Phoenix summers, we do pay to heat the neighborhood — to the tune of 1 to 2 degrees Fahrenheit — thanks to waste heat vented by our air conditioners.
