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.

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.

Is Progress Outpacing Precaution? Experts Weigh In

Illustration by An Arres.

No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist).  Is this a fair assessment? If so, should we be worried — and what can we do about it?

In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.

Genome Map Hints at How Desert Tortoise Overcomes Natural, Human Dangers

Researchers have finished the first full genome map of the threatened Mojave desert tortoise (Gopherus agassizii), also known as Agassiz’s desert tortoise.

They hope their findings will inform conservation efforts, improve understanding of its evolutionary past and potentially contribute  to  human medicine.

The Foggy Future of Refrigerants

Stable, nontoxic refrigerants changed the world, transforming food storage, expanding Sun Belt populations, even helping early movie theaters succeed. But they also wrecked the ozone layer — Earth’s shield against harmful ultraviolet radiation.

Today, as stockpiles dwindle — and prices rise — due to phase-outs set by the Montreal Protocols 30 years ago,  the future of Freon and its successors remains in doubt.
