  Title Sleepmore in Seattle: Later school start times are associated with more sleep and better performance in high school students Type Journal Article
  Year 2018 Publication Science Advances Abbreviated Journal Sci. Adv.  
  Volume 4 Issue 12 Pages eaau6200  
  Keywords Human Health  
  Abstract Most teenagers are chronically sleep deprived. One strategy proposed to lengthen adolescent sleep is to delay secondary school start times. This would allow students to wake up later without shifting their bedtime, which is biologically determined by the circadian clock, resulting in a net increase in sleep. So far, there is no objective quantitative data showing that a single intervention such as delaying the school start time significantly increases daily sleep. The Seattle School District delayed the secondary school start time by nearly an hour. We carried out a pre-/post-research study and show that there was an increase in the daily median sleep duration of 34 min, associated with a 4.5% increase in the median grades of the students and an improvement in attendance.

  Title Artificially lit surface of Earth at night increasing in radiance and extent Type Journal Article
  Year 2017 Publication Science Advances Abbreviated Journal Sci Adv  
  Volume 3 Issue 11 Pages e1701528  
  Keywords Remote Sensing; Suomi NPP; VIIRS; light pollution; *economics  
  Abstract A central aim of the â??lighting revolutionâ? (the transition to solid-state lighting technology) is decreased energy consumption. This could be undermined by a rebound effect of increased use in response to lowered cost of light. We use the first-ever calibrated satellite radiometer designed for night lights to show that from 2012 to 2016, Earthâ??s artificially lit outdoor area grew by 2.2% per year, with a total radiance growth of 1.8% per year. Continuously lit areas brightened at a rate of 2.2% per year. Large differences in national growth rates were observed, with lighting remaining stable or decreasing in only a few countries. These data are not consistent with global scale energy reductions but rather indicate increased light pollution, with corresponding negative consequences for flora, fauna, and human well-being.
