Science and Technology http://knau.org en Brain Food: Rethinking Energy Storage and Design with Smart Materials http://knau.org/post/brain-food-rethinking-energy-storage-and-design-smart-materials <p>In the near future, so-called smart materials may eliminate the need for batteries in hybrid cars and in solar panels. Cornell Ciocanel is a mechanical engineer at Northern Arizona University. He’s developing a new smart material that’s strong enough to be used in the body of a car and also stores electricity like a battery.</p><p> Thu, 10 Apr 2014 13:00:00 +0000 Bonnie Stevens 45914 at http://knau.org Brain Food: Rethinking Energy Storage and Design with Smart Materials Brain Food: Ice Age Art http://knau.org/post/brain-food-ice-age-art <p>A Northern Arizona University professor emeritus says he’s never seen anything like a recent find in the Utah desert. This, despite 25 years spent studying rock art at thousands of sites. Retired ethnolinguist Ekkehart Malotki is researching what could be the oldest known realistic engravings of Columbian mammoths in the Western Hemisphere: petroglyphs from the Ice Age near the San Juan River.</p><p> Thu, 06 Mar 2014 15:32:06 +0000 Bonnie Stevens 44244 at http://knau.org Brain Food: Ice Age Art Brain Food: Bagging an Asteroid http://knau.org/post/brain-food-bagging-asteroid <p>NASA wants to catch an asteroid, place it into orbit around the Earth, and send astronauts to retrieve pieces of it for scientific study. The agency just needs the right asteroid. NASA has asked Northern Arizona University astronomer David Trilling, one of the world’s foremost asteroid experts, to find it — a task much easier said than done.</p><p> Thu, 27 Feb 2014 12:00:00 +0000 Bonnie Stevens 43961 at http://knau.org Brain Food: Bagging an Asteroid Brain Food: The Future is Here in the Form of 3D Printing http://knau.org/post/brain-food-future-here-form-3d-printing <p>Suppose you need a wrench, or a knee replacement, or a hamburger. David Winslow Van Ness says, not a problem. In the not-too-distant future, just print one out.</p><p> Thu, 20 Feb 2014 16:19:56 +0000 Ryan Heinsius 43681 at http://knau.org Brain Food: The Future is Here in the Form of 3D Printing Brain Food: Valentine's Day In The Natural World http://knau.org/post/brain-food-valentines-day-natural-world <p>As we get ready to celebrate Valentine's Day, Northern Arizona University ecology professor Nancy Collins Johnson reminds us that we can learn a lot about relationships from nature. Collins is a soils expert who studies mycorrhizal symbiosis - or, healthy relationships between fungi and the roots of plants.</p><p> Thu, 13 Feb 2014 12:15:00 +0000 Bonnie Stevens 43372 at http://knau.org Brain Food: Valentine's Day In The Natural World Brain Food: The Discovery Channel Telescope http://knau.org/post/brain-food-discovery-channel-telescope <p>The highly sensitive camera of Lowell Observatory's Discovery Channel Telescope is painting a brighter picture of faint objects in the universe.</p><p> Thu, 23 Jan 2014 16:18:51 +0000 Bonnie Stevens 42483 at http://knau.org Brain Food: The Discovery Channel Telescope Brain Food: Spring-Loaded Muscles http://knau.org/post/brain-food-spring-loaded-muscles <p>A Northern Arizona University regents’ biology professor is studying how the speed with which frogs catch insects can improve the mechanics of artificial limbs for humans. Kiisa Nishikawa has discovered the connection is a protein called titin. It essentially enables muscles to “think,” reacting in milliseconds, rather than waiting for a signal from the brain.</p><p> Thu, 16 Jan 2014 16:34:43 +0000 Bonnie Stevens 42239 at http://knau.org Brain Food: Spring-Loaded Muscles Brain Food: Growing Human Skin http://knau.org/post/brain-food-growing-human-skin <p>Step into Robert Kellar's physiology and anatomy class at NAU and you'll learn how the human body works. But, step into his lab an you'll learn how to grow human skin. Dr. Kellar can teach plants how to manufacture human protein.</p><p> Thu, 05 Dec 2013 18:01:04 +0000 Bonnie Stevens 40589 at http://knau.org Brain Food: Growing Human Skin Brain Food: iPads Become New Field Tool For NAU Geology Students http://knau.org/post/brain-food-ipads-become-new-field-tool-nau-geology-students <p>It's estimated that by the new year, more than 60 million Americans will be using iPads. NAU geologist Lisa Skinner is already using them in the field with her students as a geologist time machine of sorts.</p><p> Thu, 28 Nov 2013 14:14:30 +0000 Bonnie Stevens 40310 at http://knau.org Brain Food: iPads Become New Field Tool For NAU Geology Students Brain Food: The One Gene Difference http://knau.org/post/brain-food-one-gene-difference <p>Some scientists predict the Southwest will continue on its warming trend. NAU biology professor Tom Whitham says the rise in temperatures is happening so fast - 3 degrees in the last 60 years - that many plants are not able to adapt and survive.</p><p> Thu, 14 Nov 2013 12:09:00 +0000 Bonnie Stevens 39693 at http://knau.org Brain Food: The One Gene Difference
