I'm no biologist nore do I have any real grasp of science. I was just wondering what thoughts, those of you in the know, have about this article.

Heres the abstract:

Louis may be jumping to conclusions revisiting the panspermia hypothesis. And it appears there is still much work to do but at least Louis is doing the right things, like having his peers attempt to replicate his findings.

There aren’t enough results to make any judgment yet. We need to let some biologists do some proper analyses instead of leaving it to bumbling physicists who are wasting time with electron microscopy which will not tell us whether they are living cells or not.

Very unusual, probably just cosmic dust. However nothing should be ruled out, perhaps our definition of life needs to be expanded.

Would cosmic dust really replicate itself?
