The largest recorded meteorite to strike the United States in 21 years fell into NOAA’s Olympic Coast National Marine Sanctuary, and researchers have recovered what are believed to be pieces of the dense, interstellar rock after conducting the first intentional hunt for a meteorite at sea.  

As global temperatures rise due to climate change, the number of air conditioning units in use globally is expected to quadruple by mid-century, increasing from 3.6 billion today to 14 billion in 2050, according to a new report by scientists at the University of Birmingham in the United Kingdom. As a result, the world will consume five times more energy for cooling than it does today.

Physician burnout is at least equally responsible for medical errors as unsafe medical workplace conditions, if not more so, according to a study led by researchers at the Stanford University School of Medicine.

New research from the University of Guelph is dispelling a commonly held assumption about climate change and its impact on forests in Canada and abroad.

Those wispy, iridescent, high-altitude clouds sometimes seen at dawn and dusk are becoming more visible due to climate change, according to a new study published in the journal Geophysical Research Letters. Rising methane emissions have increased the amount of water vapor in the middle atmosphere, the study found, which then freezes around specks of dust to form the clouds.
