SUMMARY: A team of scientists from the University of Glasgow have developed a method they believe will help detect evidence of life in ancient rocks - perhaps helping uncover if there's life on Mars. With their technique, the rocks are crushed to release tiny amounts of liquid water, and then special detectors are used to search for the presence of biomolecules in the water. Once the technique has been proven to work, the researchers believe it could be miniaturized and flown aboard future Mars landers.

This is a wonderful technique but would it not be better to use all these brains and billions to get a bloody bucket of water in Benin?
We are reaching the worst episode of scientific madness: Find Life on Mars and loose it on earth.
Where, by God, have your ethics gone?

People are fascinated by space, and the possiblity of there being life 'out there'. We need to explore space, and we need to start now.

I admit that we need to help 3rd world countries, but I also believe that space should be explored as well. How about cutting the defense budgets from countries and putting it to help less fourtunate countries. There are trillions of dollars spent on defense, so why can't a small portion of this be relegated to help less fortunate countries.

It would be nice if all countries abolished military spending, but in this day and age with terrorists, it is not an achievable dream.

The carbonate globules have been estimated to have formed in anaerobic processes.
At ambiant pressure of one atmosphere(1):
the formation of well crystalline magnesite occure at 511C
the dissociation of the magnesite to periclase occure at 548C
This also on Mars at late NOachian 1,5-3 bars atmospheres with the evolution of CO2: The orientation and location of the periclase crystals in ALH84001 provide that they formed inside the carbonate crystals as a result of thermal decomposition and loss of carbon dioxide.

Kent, in economical terms the only way to waste money is to put it under your pillow and leave it there, or use it to light your cigars.
I&#39;m not an expert in this field, but before you make a big fuss please go and ask an economist or better a socioeconomist what the term "cash flow" means ok?

Or simply put: if the scientists develop more of these "expensive techniques" and get paid better for working more, THEY will probably give part of the additional money they earned to an organiziation which brings water to Benin.

Also if you worry about the ethics of people and organizations who could spend some money on helping developing countries instead of more useless stuff, then please sit down and write e-mails to Bill Gates, the Vatican, Delta Airlines, some Arab Oil Sheiks and, last but not least, GEORGE BUSH&#33; :D

Do you mean we can not do anything before bring water to Benin?

Firstly, life has already been found in Benin so there&#39;s no point in going there ... secondly that was a joke ...

thirdly ...

Another story, HERE (http://www.universetoday.com/forum/index.php?showtopic=1059), said that mars has been dry for a billion years. So how exactly is this method going to work? If Mars is completely dry then you might as well be trying to squeeze blood from the stones instead of water.
