No increase in patient deaths or readmissions following restrictions to residents' hours

A recent study published in JAMA found that restricting residents' work hours to 16-24 hours per shift had no impact on patient deaths or readmissions. The researchers analyzed nearly 6.4 million Medicare patient hospital admissions between 2009 and 2012, but found no relative changes in mortality rates during this time period.

Abandoned wells can be 'super-emitters' of greenhouse gas

Researchers at Princeton University found that many abandoned oil and gas wells in Pennsylvania leak substantial quantities of methane. The study suggests that these 'super-emitting' wells could be a significant source of greenhouse gas emissions, potentially accounting for up to 10% of methane from human activities in the state.
