Pentagon Researches Ways to Boost Learning in Soldiers

Eight U.S. Department of Defense brain studies, one at Arizona State University, are investigating ways to help soldiers learn more efficiently.

The Defense Advanced Research Projects Agency (DARPA) hopes not just to make better sharpshooters, but also to shorten training periods for translators, analysts and cryptographers — and, perhaps, to improve outcomes for soldiers with brain injury and memory loss.

Study: Expect Southwest U.S. Monsoon Storms to Intensify

The most extreme monsoon storms are growing more intense in central and southwestern Arizona, according to a study by the University of Arizona and the National Autonomous University of Mexico.

The findings conform to patterns expected under climate change conditions. Indeed, experts have already observed this effect.

Taking the Mystery Out of Microbursts

Phoenix, Arizona, is not known for strong winds, but that all changes when monsoons annually deliver destructive downdrafts like the one that damaged its five-story Burton Barr Central Library. In this piece, and in the interview that follows it, I clear up some of the confusion that still  whirls around these blasts.

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.

Take Summer Headaches Seriously, Warns Neurologist

“The Headache” by George Cruikshank.

Between the heat, dehydration, air quality and July 4 fireworks, many Arizonans shrug off headaches as just another symptom of summer.

But Kerry Knievel, director of headache neurology at Barrow Neurological Institute, said we need to start taking headaches more seriously.
