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.

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:

NASA’s Discovery Program has selected two projects, both with Arizona ties, to delve into the ancient history of the solar system.

One craft, Psyche, will head to the asteroid belt between Mars and Jupiter. The other, Lucy, will explore six asteroids that share an orbit with Jupiter. Scientists believe that the targets embody different aspects of early solar system history.

Rude Burials Might Have Fueled Blood Feuds Among Ancient Sonorans

Bodies buried  in unusual postures and without funeral rites could suggest a history of revenge and blood feud in certain ancient Sonoran Desert cultures, according to a paper in the August 2016 edition of Current Anthropology.

The authors say a rude burial would have deeply distressed the victim’s family and community — and sent a message of dominance and defiance. Read/listen to my full story at KJZZ’s Arizona Science Desk:
