Cybercriminals of the future may be able to do a lot more than steal identities, mine for data and interfere with computer systems. Sophisticated hackers could shut down power grids, hospitals, planes and more, says Bertrand Cambou, a researcher and professor at Northern Arizona University’s School of Informatics, Computing and Cyber Systems.

The Navajo Generating Station is slated to close in 2019, and officials are considering several potential buyers to prevent the shutdown. In July, U.S. Interior Secretary Ryan Zinke and Salt River Project officials met with the U.S.-based company NantWorks. They discussed converting the coal-fired plant into a high-powered solar facility incorporating a new energy storage technique using molten salt. To find out exactly what this technology is, KNAU’s Ryan Heinsius spoke with University of Arizona engineering professor Peiwen Li who specializes in renewables.

The symptoms of Valley Fever can present like the flu: headache, chest pain, cough, fever. But scientists are still uncertain why some people become extremely ill – or even die - and others live with it for years symptom-free. Now, a team of Flagstaff biologists is developing a DNA-based test to detect the fungus.

Researchers are learning more about human voices by studying grasshopper mice. Their call, barely audible to human ears, is produced the same way that humans speak. Northern Arizona University Biologist Bret Pasch says the rodents stand upright, tilt their heads back and flare their mouths, like an opera singer.
