A study published in CMAJ found that nonmilitary personnel in Iraq and Afghanistan were more likely to be medically evacuated with non-war-related injuries, returning to duty after such injuries. Military personnel, however, were more likely to be evacuated for war-related injuries.
A study by Johns Hopkins Medicine found that civilians with noncombat injuries are more likely to be evacuated for treatment, but also more likely to return to work in war zones due to higher salaries. In contrast, soldiers are less motivated to return after such injuries, possibly due to the loss of hazardous duty pay.

The Fermilab experiments have excluded a quarter of the expected Higgs mass range, with a new mass range established at 158-175 GeV/c^2. The Standard Model predicts a mass range of 114-185 GeV/c^2.
A study by USC Marshall School of Business finds that luxury brands charge more for 'quieter' items with subtle logo placement and size, appealing to patricians. Counterfeiters predominantly copy lower-priced, louder luxury goods, while poseurs are more likely to express intent to purchase counterfeit bags.
A recent study found that data presented in frequency format elicits higher confidence and more accurate conclusions in consumers. In contrast, percentages appear easier for consumers to understand, but may lead to averaging errors. The results have practical implications for regulators trying to discourage smoking behavior.
