Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) have been hard at work studying the solar corona, the outermost atmosphere of the sun that expands into interplanetary space. 

To answer a question crucial to technologies such as energy conversion, a team of researchers at the University of Michigan, Purdue University and the University of Liverpool in the U.K. have figured out a way to measure how many “hot charge carriers”—for example, electrons with extra energy—are present in a metal nanostructure.

As communities across the U.S. have struggled to cope with the effects of the COVID-19 pandemic, many have focused on the lack of widespread testing as a major barrier to safely reopening the country.

University of Michigan scientists and their colleagues are forecasting this summer’s Gulf of Mexico hypoxic area or “dead zone”—an area of low to no oxygen that can kill fish and other marine life—to be approximately 6,700 square miles, roughly the size of Connecticut and Delaware combined.

Our new study published in Economic Modelling shows that owning and using an Air Conditioner greatly increases the electricity bills of households, with important implications for the energy poverty of the less well-off.
