Utah’s iconic Rainbow Bridge hums with natural and man-made vibrations, according to a new University of Utah study, published September 21 in Geophysical Research Letters. The study characterizes the different ways the bridge vibrates and what frequencies and energy sources cause the rock structure to resonate. The vibrations are small, according to geology and geophysics professor Jeff Moore, but the study provides a baseline measure of the bridge’s structural integrity and shows how human activities can rattle solid rock.
Plant diversity in intercropping leads to more diversity below ground too. Researchers work to find the right combination for optimal crop and soil performance.
The global aviation industry has pledged that by 2050, it will reduce its net carbon emissions to half its 2005 levels. Achieving this will require not only improved engine efficiency and aerodynamics, but also a turn to renewable jet fuel. The transition has begun, but biofuel makers need more funds and policy support to ramp up production, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
