Health Inequalities Are A Growing ProblemGlobal health inequalities are substantial, growing, and influenced by economic, social and health-sector variables as well as geography, a study concludes in the recent issue of the Journal of Epidemiology and Community Health.
Particularly disturbing findings from this study are that countries with high mortality in young children are making slow progress, gaps in adult mortality are becoming wider, and countries with the highest adult........Go to the My-media-blog (Added on 11/29/2006 4:59:11 AM)
Painkillers May Threaten Power Of VaccinesWith flu-shot season in full swing and widespread anticipation of the HPV vaccine to prevent cervical cancer, a new University of Rochester study suggests that using common painkillers around the time of vaccination might not be a good idea.

Dramatic Shift In Marine Ecosystems Occurred 250m Years AgoThe earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's oceans.
Ecologically simple marine communities were largely displaced by complex communities. Furthermore, this apparently abrupt shift set a new........Go to the My-media-blog (Added on 11/26/2006 7:58:08 AM)
