Physically fit students score higher on tests than their less fit peers

Test scores dropped more than one point for each extra minute it took middle and high school students to complete a 1-mile run/walk fitness test.

65% of the students were below the state fitness standard. Compared with these students, students who met or exceeded fitness standards had higher average test scores. Overweight and obese students also scored significantly lower on tests.

Schools may have to reverse their recent disinvestment in physical education ostensibly for the purposes of boosting student achievement.

Exercise slows telomere shortening (and aging). Telomeres are the chromosome tips which shorten each time a cell divides, making them a possible marker of aging. A study of 2400 twins showed that physically active people had longer telomeres than sedentary people.

Participation in sport is associated with a with a 20—40% reduction in all-cause mortality compared with non-participation. Exercise might also be considered as a fifth vital sign, according to the Lancet: http://goo.gl/gyxYf

Women in US academic medicine earn $13,000 less than male peers

A survey of 3,000 faculty members at the top 50 US medical schools has shown that women members earned $13,000 less than their male counterparts with the equivalent career position and professional activity.

There were no obvious reasons for the difference.

According to the study authors, "despite increased national attention to gender inequalities in salary, women in the life sciences at all academic ranks, both PhDs and MDs, continued in 2007 to receive lower annual salaries than did their male counterparts."
