Invasive Algae Kills Thousands of Shad in Arizona Lake

A population explosion of golden algae, a fast-growing invasive plant, has killed thousands of threadfin shad and some gizzard shad at Apache Lake, a reservoir in central Arizona.

Zebrafish Make a Big Splash in Arizona Medical Research

Mammals might seem like better human stand-ins than a minnow’s striped cousin, but zebrafish resemble us in surprising and useful ways. But zebrafish also offer practical advantages over other model species: They’re cheap, hardy, breed like rabbits on Viagra, and their skin can be made transparent.

For Pancreatic Cancer, Biomarker Test Offers Chance for Early Detection

When cancer is detected,  the interaction of two nanoparticles creates a bright yellow signal (photo by Fei Lu, Houston Methodist Research Institute).

Pancreatic cancer is the fourth leading cause of cancer deaths in the United States each year, in part because around four-fifths of cases go undetected until they have reached an advanced stage. But a new, biomarker-based test could soon change all that — and offer a way to monitor treatment outcomes.

Arizona’s Kartchner Caverns Steeped in Science, Secrecy

When co-discovers Gary Tenen and Randy Tufts found the blowhole entrance to the caverns in 1974, they did something extraordinary: They kept it a secret.  And when they could no longer shield the caves through secrecy, they sought out science to help protect Kartchner Caverns post-development.

Research has supported Kartchner ever since, but the reverse is true as well. Read/listen to my full story at KJZZ’s Arizona Science Desk to find out how:

Native Americans See Major Drop in Diabetes-Related Kidney Failure

The Centers for Disease Control and Prevention (CDC) reports that rates of diabetes-related kidney failure among Native Americans dropped more than 54 percent between 1996 and 2013.

The finding were published by CDC and the Special Diabetes Program for Indians (SDPI), a $150 million annual grant program coordinated by the Indian Health Service.
