University of Utah study listens to the natural bridge vibrate and sing
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.

The fall foliage season that prompts millions of Americans to undertake jaunts into the countryside each year could come much later and possibly last a little longer within a century, according to new research. (more…)
How Culture Influences Violence among the Amazon’s ‘Fierce People’
When Yanomamö men in the Amazon raided villages and killed decades ago, they formed alliances with men in other villages rather than just with close kin like chimpanzees do. And the spoils of war came from marrying their allies’ sisters and daughters, rather than taking their victims’ land and women. (more…)
Open a door and watch what happens — the hinge allows it to open and close, but doesn’t permanently bend. This simple concept of mechanical motion is vital for making all kinds of movable structures, including mirrors and antennas on spacecraft. Material scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working on new, innovative methods of creating materials that can be used for motion-based mechanisms. (more…)
While African wildlife often run afoul of ranchers and pastoralists securing food and water resources for their animals, the interests of fauna and farmer might finally be unified by the “Sodom apple,” a toxic invasive plant that has overrun vast swaths of East African savanna and pastureland.
Should the ominous reference to the smitten biblical city be unclear, the Sodom apple, or Solanum campylacanthum, is a wicked plant. Not a true apple, this relative of the eggplant smothers native grasses with its thorny stalks, while its striking yellow fruit provides a deadly temptation to sheep and cattle. (more…)
If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models.
In the virtual Earths of the models, interlocking mathematical equations take the place of our planet’s atmosphere, water, land and ice. Supercomputers do the math that keeps these virtual worlds turning — as many as 100 billion calculations for one modeled year in a typical experiment. Groups that project the future of our planet use input from about 30 such climate models, run by governments and organizations worldwide. (more…)
