A fluctuating tilt in a planet’s orbit does not preclude the possibility of life, according to new research by astronomers at the University of Washington, Utah’s Weber State University and NASA. In fact, sometimes it helps. That’s because such “tilt-a-worlds,” as astronomers sometimes call them — turned from their orbital plane by the influence of […]
The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record. By analyzing samples from the Greenland ice sheet, University of Washington atmospheric scientists found clear evidence of the U.S. Clean Air Act. They also discovered a link between air acidity and how nitrogen is preserved in […]
Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of a single molecule. Alexander Shestopalov, an assistant professor of chemical engineering at the University of Rochester, has done just that, […]
Scientists have long been trying to understand how the Andes and other broad, high-elevation mountain ranges were formed. New research by Carmala Garzione, a professor of earth and environmental sciences at the University of Rochester, and colleagues sheds light on the mystery. In a paper published in the latest Earth and Planetary Science Letters, Garzione […]
