Zothecula writes: People often state that certain planets are too hot, cold or toxic to support life. The catch, however, is that those people are really just talking about life as we know it here on Earth. By that same token, when rovers exploring other planets seek out chemical signatures associated with life forms, they’re only able to identify chemicals that we know to look for. That’s why Swiss scientists from the EPFL research center have created a device that identifies microscopic life based on nanoscale movements instead of chemistry (abstract).
