		<description><![CDATA[Check out this summary of results on aging in nematodes.  The layman&#8217;s summary is this:
Aging is thought to be due to accumulated damage.  As we age our bodies get lots of microscopic injuries and accumulated cellular damage.  Over time it adds up and our bodies break down and we die.  This is the prevailing hypothsis [...]]]></description>

Here's the thing: you cannot compare 2 financial deals simply by adding up all of the payments and seeing which is bigger, because there is such a thing as the "time value of money."]]></description>

Now I'm in R&#038;D in the biotech industry. The drug industry has problems, but Andy's accusation that we don't care about speed, that we give up when a trial goes wrong, that we are not as good at innovation is just outrageously incorrect.]]></description>

A quick explanation of homeopathy: you put some &#8220;stuff&#8221; in water, then you dilute it.  The real kicker is that in [...]]]></description>

Dr. Roy said the salt water isn&#8217;t burning per se, despite appearances. [...]]]></description>

		<description><![CDATA[I've been involved in a few discussions recently about stem cell research, and I think there's a lot of misunderstanding, in addition to outright deception, going on in the public debates.  It's another example of attempts to politicize science, and politicize facts. The science says embryonic stem cells are the way to go. Period. End of story. If you think there's a morally unjustifiable cost associate with those benefits then just say that. That's an intellectually honest debate to have, and one that could be had in the public sphere. Saying that the facts aren't in yet is, and I say this as a scientist, retarded. Not that anti-stem cell people are retarded, because they are probably just repeating what they've heard. But the idea is retarded.]]></description>
