Martians fight back

Astrobiologist at the Johnson Space Center of NASA claimed they found evidence of microbial life from wormy-looking relics in a Martian meteorite in 1996 (see BBC NEWS | Space rock re-opens Mars debate). It turned out those relics were mostly likely produced on Earth. Now the sequel is on: the same group found more interesting things on another Martian meteorite. BTW, this meteorite has a funny legend––when it fell our planet in Egypt in 1911, it killed a dog, a poor little victim of a Martian attack. The organic matters in the meteorite could be the dog’s final revenge.
