The findings shed light on the debate about whether and when calculators should be used in the classroom. 2008-08-20 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1422&story_id=347 Melanie Moran http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1419&story_id=346 The discovery that HPE, one of the most common birth defects that affects brain formation, is caused by the interaction between mutations in two different genes may make it possible to predict the risk that this malformation will develop in individual pregnancies for the first time. 2008-08-15 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1419&story_id=346 David F.

New research from Vanderbilt University has found for the first time that mental imagery directly impacts our visual perception. 2008-07-01 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1407&story_id=342 Melanie Moran http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1404&story_id=341 Analysis of the youngest pair of identical twin stars yet discovered has revealed surprising differences in brightness, surface temperature and size, suggesting that one formed before the other. 2008-06-18 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1404&story_id=341 David F.

Among other potential applications, such a capability can be used to improve the efficacy of a new procedure for treating type 1 diabetes that has demonstrated the ability to free diabetics from insulin injections for several years. 2008-04-14 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1392&story_id=337 Sarah Bryan http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1386&story_id=335 Even bacteria need to eat. So one of the ways our bodies defend themselves against these foes is to "hide" their food, particularly the metals they crave. Now, a team of Vanderbilt investigators has discovered that a protein inside certain immune system cells blocks the growth of staph bacteria by sopping up manganese and zinc: findings that support the notion that binding metals to starve bacteria is a viable therapeutic option for treating localized bacterial infections. 2008-03-18 http://www.vanderbilt.edu/exploration/text/index.php?action=view_section&id=1386&story_id=335 Leigh MacMillan
