These findings suggest a provocative general principle at work: Molecular signals from the reproductive system affect aging and metabolism in animals -- and possibly in humans. The work also proposes a new mechanism of how this control may occur.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/277313607" height="1" width="1" /></p> http://science-nature.marc8.com/eliminating-germline-lengthens-fly-lifespan-does-reproductive-s#comments Top stories germline insulin production molecular signals reproductive system stem cells http://science-nature.marc8.com/crss/node/4018 Fri, 25 Apr 2008 08:00:00 -0500 admin 4018 at http://science-nature.marc8.com http://science-nature.marc8.com/why-synthetic-estrogens-wreak-havoc-reproductive-system <p>Researchers at Yale School of Medicine now have a clearer understanding of why synthetic estrogens such as those found in many widely-used plastics have a detrimental effect on a developing fetus, cause fertility problems, as well as vaginal and breast cancers. <p><a href="http://feeds.sciencedaily.com/~a/sciencedaily?a=HazsNa"><img src="http://feeds.sciencedaily.com/~a/sciencedaily?i=HazsNa" border="0"></img></a></p> <p><a href="http://science-nature.marc8.com/why-synthetic-estrogens-wreak-havoc-reproductive-system">read more</a></p> http://science-nature.marc8.com/why-synthetic-estrogens-wreak-havoc-reproductive-system#comments Top stories breast cancers detrimental effect fertility problems reproductive system yale school of medicine http://science-nature.marc8.com/crss/node/2661 Mon, 31 Mar 2008 00:00:00 -0500 admin 2661 at http://science-nature.marc8.com
