The research, examining the signal strength of radio waves travelling over the sea, identified late afternoons and early evenings in spring and summer as a time when enhanced signals occur.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/291694780" height="1" width="1" /></p> http://science-nature.marc8.com/weather-waves-and-wireless-super-strength-signalling-0#comments Top stories afternoons radio waves signal strength spring and summer window of time http://science-nature.marc8.com/crss/node/4685 Fri, 16 May 2008 15:15:20 -0500 admin 4685 at http://science-nature.marc8.com http://science-nature.marc8.com/pinpointing-when-fetus-develops-male-genitalia-and-birth-defe <p>New data has indicated that in rats, "male" hormones drive the decision to become a male during a window of time before male genitalia develop, and that blocking "male" hormones during this time caused male genitalia birth defects. These defects were associated with a decreased ano-genital distance, leading to the suggestion that measuring human neonatal AGD could provide a noninvasive method to predict those at risk of developing male genitalia birth defects.</p> <p><a href="http://science-nature.marc8.com/pinpointing-when-fetus-develops-male-genitalia-and-birth-defe">read more</a></p> http://science-nature.marc8.com/pinpointing-when-fetus-develops-male-genitalia-and-birth-defe#comments Top stories birth defects male genitalia male hormones noninvasive method window of time http://science-nature.marc8.com/crss/node/2040 Tue, 18 Mar 2008 02:00:00 -0500 admin 2040 at http://science-nature.marc8.com
