Size and Age of Plants Impact Their Productivity More Than Climate, UA Study Shows

The size and age of plants have more of an impact on their productivity than temperature and precipitation, according to a landmark study by UA professor Brian Enquist and postdoctoral researcher Sean Michaletz. The results have important implications for climate change models.

Brain of World's First Known Predators Discovered

A UA scientist and his colleagues have found the fossilized remains of the brain of the world's earliest known predators, from a time when life teemed in the oceans but had not yet colonized the land. The discovery reveals a brain much simpler than those known in some of the animal's prey and helps answer questions surrounding the evolution of arthropods.

Celebrating Apollo 11 – the UA’s Role in the First Manned Lunar Landing to Space Exploration Today

Since the Lunar and Planetary Laboratory was established in 1960, UA scientists have played a key role in nearly every NASA mission, from the Apollo expeditions to the upcoming OSIRIS-REx mission to an asteroid.

Tiniest Catch: UA Scientists' Fishing Expedition Reveals Viral Diversity in the Sea

Using bacteria as bait, UA scientists caught wild ocean viruses and then deciphered their genomes. They learned that the genetic lines between virus types in nature are less blurred than previously thought.

Meet the Gomphothere: UA Archaeologist Involved in Discovery of Bones of Elephant Ancestor

An ancient ancestor of the elephant, once believed to have disappeared from North America before humans ever arrived there, might actually have roamed the continent longer than previously thought. Archaeologists, including the UA's Vance Holliday, have uncovered the first evidence that gomphotheres were once hunted in North America.

Two UA Optical Sciences Students Picked for Astronaut Scholarship

Benjamin Cromey and Travis Sawyer, undergraduates in the UA optical sciences and engineering program, have been named winners of the 2014 Astronaut Scholarship, an award created by members of the Mercury 7 mission.

UA Partners With Girl Scouts to Offer Search and Rescue Engineering Camp for Girls

About 25 girls from across southern Arizona are on campus this week for a summer camp designed to show them the world-changing aspects of science, technology, engineering and math. Activities will include designing packs for search and rescue animals and building search and rescue robots.
