Prehistoric humans first traversed Australia by ‘superhighways’

May 3, 2021 • ALBUQUERQUE, N.M. — Sometime between 50,000 and 70,000 years ago, prehistoric humans took their first steps into Sahul, an ancient landmass made up of modern Australia, New Guinea and Tasmania. But nobody knows which way they went after that. “One of the really big unanswered questions of prehistory is how...

Award-winning engineer helps keep US nuclear deterrent safe from radiation

December 23, 2019 • ALBUQUERQUE, N.M. — When nuclear radiation hits electronics, it cuts through semiconductors, leaving scars of charged particles that can flip computing bits and corrupt memory circuits, potentially disabling devices or causing erratic errors. Experts like engineer Alan Mar ensure components made for the U.S. nuclear stockpile pass stringent standards to...
