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.
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.
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.
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.
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.
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.
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.
Pests can pose a serious threat to plants. Expert plant scientists and community liaisons in the Arizona Plant Diagnostic Network can help to diagnose pest-related issues affecting plants whether they’re in a back yard or a commercial agriculture enterprise.
Shaunna Morrison, a UA geosciences doctoral student who works on NASA’s Mars Science Laboratory mission, was one of the female engineers and scientists who helped run the Curiosity rover during Women’s Curiosity Day.
University of Arizona astronomy professor Chris Impey, a pioneer in the use of instructional technology to teach science, is the first astronomer to be named a Howard Hughes Medical Institute Professor.
