Ebbs and Floes: Watching the Arctic Ice Melt

By Norman Rusin @normanrusin Last July, a team of NASA scientists succeeded in collecting data about summer melting ice in the Arctic during a first-of-its-kind operation. The team surveyed the Arctic Ocean off the Alaskan coast, in Barrow, to measure the aquamarine pools of meltwater on floes—huge chunks of floating ice—that may be accelerating the overall sea ice retreat. They chose the northernmost US city because of its proximity to the ocean. However, they knew they would face unstable weather conditions there, so they would have to pursue targets of…

Conductive Concrete May End Flight Delays

By Emily Rhode @riseandsci Every year, thousands of flights are delayed and thousands of car accidents happen due to snowstorms and icy road conditions. Millions of dollars are spent each year plowing and de-icing runways, tarmacs, roadways, and bridges. Salt and plowing cause damage to roadways and waterways, and shoveling heavy snow causes injuries and deaths. Flight Delays (and Snow Days) Could be Things of the Past, Thanks to Science The Federal Aviation Administration (FAA) is very interested in a special type of conductive concrete made by researchers at the…
