- EuroNews looks at life on Mars!
02-08-2008 · European Space Agency (ESA)
Is there life on Mars? ESA's Mars Express satellite, launched in 2003, has been scanning and mapping the surface of our rocky neighbour, and it has found that there are both substantial deposits of water ice below the Martian crust and traces of methane in the Martian atmosphere. The next step is ExoMars, due for launch in 2013, which will place a lander on the surface of the red planet with the express aim of searching for past or present signs of life. EuroNews talked to the scientists at the cutting edge of this research.

- Hunting martian fossils best bet for locating Mars life, says ASU researcher
02-16-2007 · EurekAlert!
Hunting for traces of life on Mars calls for two radically different strategies, says Arizona State University professor Jack Farmer. Of the two, he says, with today's exploration technology we can most easily look for evidence for past life, preserved as fossil "biosignatures" in old rocks.Farmer is reporting on his work today (February 16) at the annual meeting of the American Association for the Advancement of Science in San Francisco.

- Finding that 1-in-a-billion that could lead to disease
08-19-2007 · EurekAlert!
Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. Now, scientists at Johns Hopkins have uncovered how the tiny protein-machines in cells tasked to search for such potentially life-threatening genetic damage actually recognize DNA errors.
