Your submissions are wanted for the sixth Hourglass blog carnival on aging and longevity science: "Topics of posts should have something to do with the biology of aging, broadly speaking - including fundamental research in biogerontology, age-related disease, ideas about life extension technologies, your personal experience with calorie restriction, maybe even something about the sociological implications of increased longevity. Opinions expressed are not necessarily those of the management, so feel free to subvert the dominant paradigm. If in doubt, submit anyway. ... In the meantime, feel free to check out previous editions of the carnival. By the way, if you'd like to volunteer to host, please email me directly - basically all of 2009 is wide open. If you've already hosted before, don't let that hold you back; while the carnival is young, some repeat hosting is going to be par for the course."
