Leading a UA research effort that has brought in almost $8 million in funding, UA Aerospace and Mechanical Engineering Department Head Jeff Jacobs conducts fundamental research in fluid instability and provides experimental data to help national laboratories validate their simulations of nuclear arms safety and efficacy.
Famed UA astrophotographer Adam Block has again captured a striking image of the cosmos. The glowing red region in the constellation Serpens, which means snake, "gives this vista an eerie feeling" while its contrasting regions bring to mind to duality of heaven and hell, Block says.
UA researchers have discovered a surprisingly diverse ecosystem of microbes in a limestone cave near Tucson, Arizona, eking out a living from not much more than drip water, rock and air. The discovery not only expands our understanding of how microbes manage to colonize every niche on the planet but also could lead to applications ranging from environmental cleanup solutions to drug development.
A National Sciences Foundation-funded exhibit, "Journey into the World of Microbes," is now open in the Discovery Center at Kartchner Caverns, offering the public a closer look at the microscopic organisms that live in the caves. The kiosk was created to educate the public about these cave microbes, including some that are being studied by UA researchers.
The UA's McGuire Center for Entrepreneurship was named Innovator of the Year in academia during the Governor's Celebration of Innovation gala. All finalists for the award were from the UA, representing innovative programs in agriculture, the biological sciences and environmental science.
FireScape is a comprehensive effort to manage fires and ecosystems in Arizona's sky island region. The project brings together representatives from the UA, the U.S. Forest Service, The Nature Conservancy, Bureau of Land Management, National Park Service and other southeastern Arizona land managers. Firescape researchers collect extensive data for each mountain range and build interactive maps to allow for a scientifically driven approach to managing fires.
A team of researchers co-led by UA Regents' Professor Nick Strausfeld has discovered the earliest known complete nervous system, exquisitely preserved in the fossilized remains of a never-before described creature that crawled or swam in the ocean 520 million years ago. Described in the current issue of the journal Nature, the specimen belongs to an extinct group of marine arthropods known as megacheirans, Greek for "large claws."
Are we alone in the universe? This is the central question posed by a new book edited by UA scientists. "Encountering Life in the Universe: Ethical Foundations and Social Implications of Astrobiology" is a compilation of works by authors ranging from philosophers and theologians to astronomers and astrobiologists. The book explores the ethical and societal implications of finding life elsewhere in the universe.
UA undergraduate researcher Sarah Schwenck and postdoctoral associate Jennifer Brum are investigating phages, viruses that infect bacteria, to understand how portions of the world's oceans function without oxygen. Having taken measurements while on a research cruise to Mexico, they will sequence the DNA of the viruses and analyze how much of a role differences in viruses plays at different spots in the ocean.
UA doctoral degree candidate Jay Sanguinetti has authored a new study, published online in the journal Psychological Science, that indicates that the brain processes and understands visual input that we may never consciously perceive. The finding challenges currently accepted models about how the brain processes visual information.
