The study's findings may affect the way researchers examine consumer choices.http://www.eurekalert.org/pub_releases/2008-06/uocp-tmc062508.php Report -- adapting farming to climate change- June 25, 2008 CSIRO today released a national overview of climate change impacts and adaptation options for Australian agriculture.http://www.eurekalert.org/pub_releases/2008-06/ca-ra062508.php Nanotubes could help study retrovirus transmission between human cells- June 25, 2008 Naturally occurring nanotubes may serve as tunnels that protect retroviruses and bacteria as they infect healthy cells. The unexpected shielding may explain why vaccines fare poorly against some invaders. Sandia researchers now have formed similar nanotubes that could be used to duplicate the phenomenon.http://www.eurekalert.org/pub_releases/2008-06/dnl-nch062508.php Sound medicine- June 25, 2008 Sound has a long history in medicine, from the stethoscopes doctors have used since the early 19th century to listen to the internal sounds of the human body to the obstetric ultrasound images so familiar to expectant parents.
