Subject: Inorganic material is alive...

Interesting report:

New studies of dust that form lifelike structures suggest that extraterrestrial life may not be carbon-based at all.

From the Institute of Physics press release:

Quite bizarrely, not only do these helical strands interact in a counterintuitive way in which like can attract like, but they also undergo changes that are normally associated with biological molecules, such as DNA and proteins, say the researchers. They can, for instance, divide, or bifurcate, to form two copies of the original structure. These new structures can also interact to induce changes in their neighbours and they can even evolve into yet more structures as less stable ones break down, leaving behind only the fittest structures in the plasma.

So, could helical clusters formed from interstellar dust be somehow alive? "These complex, self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter," says (V.N.) Tsytovich, "they are autonomous, they reproduce and they evolve".
