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.

Clock Ticking for Mexican Wolf and Recovery Plan

After 30-plus years of wrangling, wildlife managers have yet to agree on a revised recovery plan for the endangered Mexican wolf. As a November deadline looms, a study by the Arizona Game and Fish Department and British Columbia’s Wildlife Genetics International offers guidance for finding common ground.

Zoo Conservation Center Pulls Native Species Back from the Brink

As Congress eases rules for selling public lands and considers measures to weaken the Endangered Species Act, conservation efforts may rely increasingly on private facilities like the Phoenix Zoo, which supports its Arthur L. and Elaine V. Johnson Foundation Native Species Conservation Center with a portion of its gate receipts.

For 11 years, volunteer citizen scientists have gathered near Seligman, Arizona, to help spot, capture and release endangered black-footed ferrets. The outing is part of a program to monitor captive-bred ferrets that wildlife specialists began reintroducing to Aubrey Valley 20 years ago.

This year, I joined them.

Mitochondria-Linked Genetic Changes Might Give Early Hint of Alzheimer’s Disease

Long before they develop neurofibrillary tangles or beta-amyloid plaques, brains with Alzheimer’s disease begin experiencing problems in their cells’ power plants — the mitochondria — that hinder their ability to make energy for cells.

Declines in gene expression related to mitochondria can occur in subjects as young as their early 30s.
