For Some Dinosaurs, it Wasn’t the Asteroid, but the Aftermath

The recent solar eclipse plunged a swath of the U.S. into two minutes of gloom, but it’s nothing compared to the years-long night that almost wiped out life on Earth 66 million years ago.

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:

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.

Of Mammoths Wild and Woolly

We love dinosaurs, but we never shared the planet with them. Such was not the case with woolly mammoths, which we once hunted, chowed down on, and used for tools and building materials. You don’t see T-Rexes on cave walls, but some of the earliest sculpture and art by human hands depicts these elephantine throw rugs.

Today, their well-preserved remains contain muscle, blood, teeth, bone, tusk and even brain. We’ve recovered and sequenced mammoth DNA, something we’ll never be able to do with dinosaurs. But if all you know about these majestic creatures comes from old Flintstones episodes, then join me as I explore …

The Scientist and the Sea Serpent

Most seafaring cultures have sea monster myths or folktales. They are preserved in manuscripts, in the margins of old maps, on the walls of Hindu temples and in the rock carvings of American Indians. Tales tell of monstrous sea gods and their fearsome servants as well as other assorted briny beasts. But is there a drop of truth to any of these tall tales? And how might we find out? Join me as I explore…
