UA Scientists Help Decipher Origin of Flowers

UANews | December 21, 2013
Researchers have deciphered the DNA of the earliest ancestor of flowering plants, providing long-awaited insight into the evolution of the amazing diversity of the more than 300,000 flowering plant species we enjoy today.

How to Find the Rarest of the Rare in Southern Skies

UANews | December 17, 2013
An interdisciplinary UA team has received over $700,000 from the National Science Foundation to develop a computer program that will sort through between 1 and 10 million alerts of astronomical objects each night from the Large Synoptic Survey Telescope, which will begin operations in Chile in 2022.

The Virus That Makes a Disposable Syringe

UANews | December 17, 2013
For decades, no one knew how a virus that preys on bacteria transfers its DNA into the host cells because it appeared to lack the structures other viruses use for that process. Now researchers have discovered how the virus does it - using a structure that might hold applications for nanotechnology.

No Matter the Continent, the World's Frogs Have a Lot in Common, UA Biologist Finds

UANews | December 15, 2013
After studying frogs on three continents, a UA biologist has come to the conclusion that frog species have striking similarities no matter where thet make their homes. In a study published in the journal Proceedings of the Royal Society B: Biological Sciences, ecology and evolutionary biology professor John Wiens and collaborators suggest that the similarity in frog species across continents has two explanations.

The Sound of Destruction

UANews | December 15, 2013
What do kidney stones, a shrimp’s lunch, and firefighting foam have in common? The answer lies in the destructive power of sound waves, which UA researchers are investigating as a means of eliminating toxic chemicals. Manish Keswani, an assistant professor in the Department of Materials Science and Engineering, and Reyes Sierra, a professor in the Department of Chemical and Environmental Engineering, have been awarded a U.S. Air Force contract to destroy firefighting chemicals using a novel sonochemical process, which uses sound waves to break down complex and toxic molecules.

UA HiRISE Mars Camera Reveals a More Dynamic Red Planet

UANews | December 11, 2013
New scientific data obtained from images taken with UA's HiRISE Mars camera suggest salty water may be flowing at certain times of the year in Mars' equatorial region, which had long thought to be free of water or ice. HiRISE principal investigator Alfred McEwen presented the findings at the American Geophysical Union meeting in San Francisco.
