18 OCT 96 Life on Mars?
by G. Jeffrey Taylor
A group of scientists, headed by Dr. David McKay of Johnson Space Center, have made a case for ancient life on Mars based on features in a meteorite found in Antarctica. Do we indeed have evidence of life on Mars?

31 MAR 97 Not Quite a Meeting of the Minds.
by G. Jeffrey Taylor
The debate about life in martian meteorite ALH 84001 at the 28th Lunar and Planetary Science Conference was vigorous. Some investigators will turn out to be right, others wrong, but there will be no losers.

31 MAR 97 Life on Mars--The Debate Continues.
by G. Jeffrey Taylor
Scientists continue their search for answers to the question of fossil life in a martian meteorite. Have we found evidence for life, nonbiologic processes or contamination? The great debate is far from over.

22 MAY 97 Shocked Carbonates may Spell N-o L-i-f-e in Martian Meteorite ALH84001.
by Edward R. D. Scott
Evidence for redistribution of carbonates by shock casts doubt on fossil life in martian meteorite.

22 MAY 97 Low-temperature Origin of Carbonates Consistent with Life in ALH84001.
by G. Jeffrey Taylor
Evidence from magnetism and isotopes consistent with life in martian meteorite.
