It is true. A large 31 page paper was published in the Dec. 1st, 2000 issue
of the peer reviewed journal Geochimica et Cosmochimica Acta. Kathie
Thomas-Keprta from NASA Johnson Space Center and eight colleagues (from Cal.
Tech, Iowa State Univ., Univ. of Georgia, McGill Univ., and NASA-JSC ) report
on a unique crystallographic form of the mineral magnetite (along with six
unique properties of magnetites produced by magnetotactic bacteria) within
the Martian meteorite ALH84001 which is indistinguishable from magnetites
produced by the MV-1 reference magnetotactic bacteria. Another report on the
research results is given in the Dec. 22nd issue of SCIENCE in which Richard
Kerr of SCIENCE notes that the unique magnetites (which comprise only ~25% of
magnetites within ALH84001) is the strongest evidence to date for indigenous
biogenic features within Martian materials.
