unusual star system proves that stars can die quietly
May 21, 2024 (Nanowerk News) One day, the star at the center of our own solar system, the Sun, will begin to expand until it engulfs Earth. It will then become increasingly unstable until it eventually contracts into a small and dense object known as a white dwarf. However, if...
Transforming CO2 emissions into valuable products may be less costly with new technology
May 21, 2024 (Nanowerk News) A costly step in the process of taking carbon dioxide emissions and converting them into useful products such as biofuels and pharmaceuticals may not be necessary, according to University of Michigan researchers. Carbon dioxide in the Earth’s atmosphere is a key driver of climate change,...
