		<title>It&#8217;s confirmed: There is water in mars</title>
		<description><![CDATA[Laboratory tests on the vehicle explorer &#8220;Phoenix&#8221; confirmed the existence of water on the planet Mars, NASA said today. 
The U.S. space agency said yesterday that the robotic arm of &#8220;Phoenix&#8221; deposited one sample in an instrument that identified water vapor. &#8220;We have water on Mars, said William Boynton, thermal analyzer scientist at the University [...]]]></description>

		<title>Stem cells from unharmed embryos</title>
		<description><![CDATA[For the first time, stem cells from human embryos have been obtained without destroying the embryo from which they come. The breakthrough overcomes the main objection to the ethics of human embryonic stem cell (hESC) research - the embryos must be killed to get hES cells.
The new method removes a single cell from the embryo [...]]]></description>

		<title>Male infertility revealed by DNA ancestry tests</title>
		<description><![CDATA[DNA testing to establish ancestry are becoming very popular and are being offered by several companies. As the knowledge about the genetic composition of human populations accumulates, the manufacturers are including more markers to their tests in order to make them more accurate and span more ancestral lineages.
Geneticists from the Department of Genetics, University of [...]]]></description>
