Some doctors are operating on hands in a new way: with the patient wide awake. It eliminates the risks and side effects of general anesthesia. But the technique has been slow to catch on in the United States because of a decades-old myth about the dangers of injecting adrenaline into hands. From the Arizona Science Desk, Melissa Sevigny reports on how that’s starting to change.

Snowflake is a small town in eastern Arizona. It’s got more deer and elk than people, and that can make it dangerous to navigate rural roads at night. That’s why students at Snowflake Junior High invented a system of flashing lights to warn drivers when a big animal is nearby. It’s an idea that will take them all the way to a national competition in New York.

The Navajo Nation is arid and vast—nearly thirty thousand square miles. Hydrologists struggle to collect much-needed measurements of rainfall there. But now they have help from NASA satellites.

A decade ago Flagstaff suffered a blow when Pluto was “demoted” to a dwarf planet. It was discovered at Lowell Observatory in Flagstaff in 1930 and is a source of pride for the city. But astronomers voted on the definition of a planet and Pluto didn’t make the cut. Now, planetary scientists say that definition is both overly complicated and incomplete.  They’ve suggested a different one. Melissa Sevigny from the Arizona Science Desk spoke with two Lowell scientists about the definition, Will Grundy and Gerard van Belle.

The public can now join the hunt for the elusive Planet Nine, a massive planet astronomers believe might be hidden beyond Neptune.
