New Mars clay study suggests planet was too dry, hot for life
A new study of magma-formed Martian clay by French and US scientists suggests that Mars possibly never had free-flowing water. The new study contradicts previous studies that suggested the early environment of Mars had water believed essential for life.

Craig Venter Wants To Rebuild Martian Life In Earth Lab
Hugh Pickens writes "Karen Kaplan reports in the LA Times that Craig Venter is making plans to send a DNA sequencer to Mars. Assuming there is DNA to be found on the Red Planet – a big assumption, to be sure – the sequencer will decode its DNA, beam it back to Earth, put those genetic instructions into a cell and then boot up a Martian life form in a biosecure lab. Venter's 'biological teleporter' (as he dubbed it) would dig under the surface for samples to sequence. If they find anything, 'it would take only 4.3 minutes to get the Martians back to Earth,' says Venter, founder of Celera Genomics and the Institute for Genomic Research (TIGR). 'Now we can rebuild the Martians in a P4 spacesuit lab.' It may sound far-fetched, but the notion of equipping a future Mars rover to sequence the DNA isn't so crazy, and Venter isn't the only one looking for Martian DNA. MIT research scientist Christopher Carr is part of a group that's 'building a a miniature RNA/DNA sequencer to search for life ...
