An international team of researchers has reported what may be the first two isolated, salty, subglacial lakes found on Earth.
The water pockets — one roughly the area of Arizona’s Saguaro Lake, the other about four-fifths the size of the state’s Apache Lake — differ from 400 other subglacial pools in that they are 4-5 times as salty as Earth’s oceans.

Finding An Alien World Half A Mile Beneath Canadian Ice
Humans have long fixated on which mental traits distinguish us from other animals. Now, University of Arizona researchers are asking what our canine companions can tell us about ourselves.
In this feature, I take you behind the scenes of this laboratory and introduce you to some of its remarkable minds, both two- and four-legged.

Years-Long Darkness Doomed Survivors Of Dinosaur-Killing Asteroid
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:
At Arizona’s Kartchner Caverns, Science Supports Stewardship — And Vice Versa
An Arizona State University program this semester will use veterans to archive digital archaeological data from the U.S. Army Corps of Engineers.
The four veterans will train and work at ASU’s Center for Digital Antiquity, which houses the nation’s largest archive of digital archaeological data.
