A new survey of over 10,000 Americans found that nearly 50% of evangelicals believe science and religion can work together, contrary to public perception. The study also showed that scientists are more likely to practice their faith than the general population, challenging conventional wisdom.
A study of nearly 100,000 kidney donors found a small increased lifetime risk of developing end-stage renal disease following donation compared to healthy nondonors. The estimated cumulative incidence of ESRD at 15 years after donation was higher in donors than healthy nondonors, with blacks having the highest absolute risk.
A Michigan State University scholar found that Latino and black candidates won as often as their white counterparts when running for office. The study suggests that parties should recruit more minority candidates to address the lack of representation in elected offices
