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.

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.

Mesa Verde Builders Possibly Used Geometry in Sun Temple

A sacred site built in southwest Colorado around 800 years ago hints that the ancestral Pueblo people might have used geometry.

The analysis of the Sun Temple at Mesa Verde National Park offers the first hard evidence that a prehistoric North American society possibly employed such figures in construction.

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.
