Purdue researchers solve decades-old corn, sorghum problem

A team of Purdue University researchers has identified the genetic mechanism responsible for dwarfed appearance in corn and sorghum plants. This finding may help develop dwarf forms in other crops, improving food production in certain regions. The study also reveals a genetic phenomenon involving direct duplication that causes instabil...

Gender and geography increase racial disparities in health care, Dartmouth study shows

A Dartmouth study analyzing Medicare data from 1998-2000 found that racial disparities in knee replacement surgery exist not only by sex but also by geographic location. Despite similar rates among African-American women and white women, black men were half as likely to undergo the procedure as their white counterparts.
