Blame air currents for the East Coast’s warm spell, and also climate change

The US East Coast has been unusually hot this week, breaking temperature records from Boston to Washington, DC. But what’s causing this sudden warm spell?

The answer has to do with the air currents in the atmosphere, according to Mark Chenard, a meteorologist at the Weather Prediction Center in College Mark, Maryland. Most of the time, winds in the atmosphere flow from west to east; this is called “zonal flow” and it’s responsible for our everyday weather. But every once in a while, the winds start flowing north to south, creating a pattern called “amplified flow.”

“Cold air from north comes down south, and warm air from the south goes north,” he says. So, warm air from the Gulf of Mexico is floating upward toward those of us in the…

Researchers use electric currents to detect cancer in human tissue

In a study published recently in Angewandte Chemie, researchers demonstrated that an imaging technique called scanning electrochemical microscopy could become a very useful medical tool. Rather than having to use additional chemicals like dyes or flu…

A device that turns currents into electricity could make tidal energy a reality


There’s no doubt that tidal power is severely lagging behind other forms of renewable energy like wind and solar power. However, as two-thirds of the Earth’s surface is covered by water, we’d be crazy not to try and harness energy from water that’s continuously in motion. Given the high costs of creating new technology and the fact that there is yet to be an agreed upon design that works, the tidal energy industry is yet to take off. Germany based company, REAC Energy GmbH wants to change that. They have developed the StreamCube, a scalable, cube-shaped water wheel that might be…
