Silkweaver says: If a bacteria cell finds itself in a dangerous situation - for example, if the temperature or saltiness of the bacteria's environment reach dangerous levels which threaten the survival of the bacteria -a warning signal from the cell's surface is transmitted into the cell. Using cutting edge electron microscopy imaging techniques the authors of the new research observed that the stressosomes receive this warning signal, and in response several proteins called RSBT break away from the large stressosome. This breakaway triggers a cascade of signals within the cell which results in over 150 proteins being produced - proteins which enable the cell to adapt, react and survive in its new environment. Sometimes I wonder if bacteria are really at the top of the evolutionary chain. They clearly survive better, reproduce better, and adapt better than humans do. |
