Climate Change to Broil Cities
Cities' ability to store heat means they are typically warmer than their surrounding areas. Given climate change, this could mean the end of cooler nights and more frequent heat waves.
Cities' ability to store heat means they are typically warmer than their surrounding areas. Given climate change, this could mean the end of cooler nights and more frequent heat waves. "Instead of being consumed by plants or transported away by soil moisture, much of the daytime heat directed into urban areas is absorbed by hard, impermeable surfaces that have no other way of releasing their stored heat except to re-radiate it at night. This gives residents of urban areas little relief from the summer heat long after the sun sets...This stored heat will only get worse with increased atmospheric carbon dioxide, said Mark McCarthy, lead author and a research scientist with the Climate Impacts team at the Met Office, the United Kingdom's weather service."
The ability to speak clearly, succinctly, and powerfully is easier than you think
The ability to communicate effectively can make or break a person's assessment of your intelligence, competence, and authenticity.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
