Water levels in Colorado River reservoirs like Lake Mead, shown here in 2918, and Lake Powell continued to fall to dangerously low levels in 2022, triggering a series of cuts in the amount of water states can pull from the river beginning this year.

Dr. Theresa Cullen, Pima County's health director, was chosen to take over ADHS, replacing Don Herrington, who has been the interim director since Aug. 26, 2021, shortly after Dr. Cara Christ left the position. Christ made her exit at a time when Gov. Doug Ducey held his stance against a statewide mask mandate despite CDC recommendations to mask and rising COVID case numbers.

Across the country, health officials have been trying to combat misinformation and restore trust within their communities these past few years, a period when many people haven’t put full faith in their state and local health departments. Read more»

Gordon Brown credits hyperbaric oxygen therapy for his recovery from a traumatic brain injury he suffered two decades ago.

HBOT of Arizona uses the therapy to treat thousands of brain injury patients – roughly 2,000 this year – and although the Food and Drug Administration has not approved hyperbaric oxygen for that purpose, patients are not deterred from trying off-label treatments. Read more»

An Arizona National Guard soldier tests a member of the Tohono O’odham Nation for COVID-19 in Santa Rosa in August, 2020.

The true toll of the COVID-19 pandemic on many communities of color — from Portland, Oregon, to Navajo Nation tribal lands in Arizona, New Mexico and Utah, to sparsely populated rural Texas towns — is worse than previously known. Read more»

COVID-19 cases and deaths are down sharply from the height of the pandemic, but COVID-19 has still been responsible for more than 2.3 million infections and 32,182 deaths in Arizona in the past three years, and health experts say it’s likely here to stay.

Almost three years after the first COVID-19 cases were detected in Arizona, here’s what we know: It hits the elderly hardest, it spikes in summer and winter, it killed men in Arizona at sharply higher rates than women and new strains continue to evolve. Read more»

The cost-estimator tools could be useful for the increasing number of people with high-deductible health plans who pay directly out-of-pocket for much of their health care before they hit that deductible.

As of Jan. 1, health insurers and employers that offer health plans must provide online calculators for patients to get detailed estimates of what they will owe — taking into account deductibles and copayments — for a range of services and drugs. Read more»

Republican candidate Abe Hamadeh, who lost the election to Arizona Attorney General-Elect Kris Mayes and then challenged the results in court.

The final recount results released Thursday in the Arizona attorney general’s race — which shrank to a razor-thin margin of 280 votes and confirmed Democrat Kris Mayes’ victory — show that ballot-counting errors in Pinal County were largely responsible for the shift. Read more»

Textbooks in the 70s and 80s focused primarily on describing the mechanics of the greenhouse effect, whereas books published in later decades contained significantly more information on harms such as sea level rise, risks to human health, species loss, extreme weather and food shortages. 

Evidence is mounting fast of the devastating consequences of climate change, but a study found that most college biology textbooks published in the 2010s contained less content on climate change than textbooks from the previous decade. Read more»

A spokesperson for Southwest Airline — the largest in 23 of the nation’s top 25 travel markets — said that it was slashing flights and halting ticket sales for the coming days while it recovers.

Dallas-based Southwest Airlines faces a federal investigation into whether it violated its own legally required customer service plan amid a blizzard of flight cancellations that ruined plans and angered travelers over the Christmas holiday. Read more»

People have been wrongfully accused and convicted of murder after someone misinterpreted their call for help, while those who used 911 call analysis against them face little or no consequences.

Junk science in the justice system is nothing new, and the system is at its most opaque when prosecutors know evidence - like 911 call analysis - is unfit for court but choose to game the rules, hoping judges and juries will believe it and vote to convict. Read more»
