Tiny tunnels in Mars rock hint at life's traces
"A study of a meteorite that fell in Egypt nearly 95 years ago may offer clues in the search for possible life on Mars.
Researchers studying the meteorite that originated from Mars found a series of microscopic tunnels within the object that mimic the size, shape and distribution of tracks left on Earth rocks by the feeding frenzy of bacteria.
The discovery of the tiny burrows adds intrigue to the search for life beyond Earth. However, no DNA could be extracted from the meteorite, so it's not known if the tunnels are of biological origin. The scientists said the lack of DNA does not derail the prospect."
