His research at the UA Orthopedic Research Laboratory grows cartilage from stem cells taken from fat tissue on scaffolding that mimics the structure of a normal bone.




AME Alumnus Loves Locomotives

Eric Hadder has loved trains since he was two years old.

Pursing that passion brought him to the UA, where he received a bachelor's degree in mechanical engineering in 1995. Hadder explains his pathway to chief mechanical officer at the Grand Canyon Railway in an interview with the New York Times.

He serves as a mentor in the University of Arizona Cooperative Extension's 4-H Youth Development Program in his hometown of Douglas.

The program has taken him around the country to learn more about 4-H and its ideals on healthy living and eating – and to Mexico City, where he contributed to the development of an equivalent program.

Portrait of William R. AssenmacherThe Mining Foundation of the Southwest has selected William R. Assenmacher, CEO and principal owner of CAID Industries, to receive a 2016 Medal of Merit.

Assenmacher, who graduated from the University of Arizona with a degree in mechanical engineering in 1974, will be recognized for his contributions to the mining sector in a ceremony in Tucson on Dec. 3.  




Warnock Helps Take Gliders to Record-Breaking Heights

Cover of July 2016 Smithsonian Air & Space Magazine featuring the Perlan gliderThe current altitude record for level flight by a piloted aircraft is just over 85,000 feet, but the Perlan Project hopes to take their sailplane to 90,000 feet this summer, using stratospheric mountain waves near the Antarctic polar vortex.

University of Arizona alumnus Ed Warnock is helping the Perlan Project reach those heights. The 1968 graduate of UA's aerospace engineering program currently serves as the nonprofit's CEO.

Read more about the project, and Warnock's work, in the cover story of the July issue of Smithsonian Air & Space magazine.
