How Heat Makes You Dumber: The Science of Cognitive Performance in Summer
The Brain Has a Temperature Problem The human brain is extraordinarily sensitive to temperature. It operates optimally within a narrow range — core body temperature between approximately 97°F and 99°F — and performs measurably worse outside this range. The same heat that makes outdoor physical activity harder in July also impairs the cognitive work that […]
The Floods of 2008: When the Midwest’s Rivers Refused to Stay in Their Banks
The Flood That Followed a Wet Spring In June 2008, the rivers of the Midwest rose to levels that hadn’t been seen since the catastrophic floods of 1993 — and in some locations, to levels that exceeded even that benchmark.
