In a recent study conducted by Hongri Gong and colleagues, a respiratory supercomplex was isolated from the bacterium Mycobacterium smegmatis, and its structure was visualized at a resolution of 3.5 Å using cryo-electron ...
All schoolchildren learn that the difference between eukaryotes and prokaryotes has something to do with a nucleus. This is usually around the same time they learn that the mitochondria is the powerhouse of the cell. The ...
It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...
