By using tree rings, a UA-led team developed the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century — back to 1725.

A four-year effort involving Kitt Peak's Bok Telescope and UA students helped a team of astronomers measure the masses of a large sample of supermassive black holes. Despite its modest size and advanced age of almost 50 years, the instrument keeps churning out big science.

At the core of the system licensed by GUIA is the ability to sense a miner's location and body temperature, predict potential problems and recommend steps to avert health risks.
