"The Bureau of Reclamation has been gathering data on U.S. rivers since 1922, and there’s now a water shortage on part of the Colorado River for the first time in 99 years of records.

Lake Mead, near the Arizona-Utah state line, is where the shortage is. Arizona farmers are being hit with water cuts as a result. Millions of Americans rely on the Colorado River system for water and hydroelectric power. Bureau of Reclamation statistics show Lake Mead is just 35% full."

"The University of Arizona-backed mission's main goal was to collect a surface sample from the asteroid Bennu and bring it back. But the U of A's Dante Lauretta explains OSIRIS Rex is also sending back details about asteroids like Bennu that are a threat to collide with the Earth."

OSIRIS-REx helps scientists project asteroid orbits Data shows that Bennu will eventually make a close fly-by of Earth.

Rosalind Franklin may have been the first person to photograph the structure of DNA, but this was just one of her accomplishments within STEM. 🧬👩‍🔬🔬

"A new exhibit at the Arizona History Museum in Tucson aims to make sure the state’s place in the history of space flight is not forgotten.

"Ben Wilder, director of the University of Arizona’s Desert Laboratory, said last year was the driest on record in Tucson and he suspects this year’s strange bloom is a response to that.

Although he can’t prove it, Wilder said what’s happening now could be fallout from a run of record heat in 2017 that damaged many of the cacti, disrupting their development."

Unprecedented outbreak of side blooms on saguaros in Arizona TUCSON, Ariz. (AP) — Cactus experts are tracking an unprecedented outbreak of “side blooms” on saguaros across Southern Arizona this year. Typically, the giant cacti sprout flowers only around the tips of their arms and trunks.
