The reverberations from earthquakes as they bounce back and forth through the centre of Earth have revealed new details about the structure of the planet’s inner core, according to a study published in Nature Communications this week.
During the last decade lead halide perovskites have shown great potential for photovoltaic applications. However, the stability of perovskite solar cells still restricts commercialization, and lack of properly implemented unified stability testing and disseminating standards makes it difficult to compare historical stability data for evaluating promising routes towards better device stability.
In the last few weeks, the United States shot down several flying objects that they suspected to be spy balloons — although most of them were probably benign. Balloons have roles in science, too: some that are used to test high-altitude instruments can expand to become bigger than a football stadium and can carry up to three tonnes.
