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.

Huge Antarctic iceberg makes a big splash on sea life

A massive Antarctic iceberg, C-19, blocked the movement of sea ice in the Ross Sea region, resulting in unusually high sea-ice cover and a significant reduction in primary production. This study used satellite imagery and chlorophyll data to quantify the effects of the iceberg on phytoplankton growth.
