Vector Electric Field Instrument-Electromagnetic Waves-Solar System-Signature-Earth

Lightning signature could help reveal the solar system's origins

Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere. This electromagnetic signature, known as Schumann Resonance, had only been observed from Earth's surface until, in 2011, scientists discovered they could also detect it using NASA's Vector Electric Field Instrument (VEFI) aboard the U.S. Air Force's Communications/Navigation Outage Forecast System (C/NOFS) satellite. In a new paper, researchers describe how this new technique could be used to study other planets in the solar system as well, and even shed light on how the solar system formed. read more..

Sense Of Fairness-Climate Change-Science Team-Playground-Earth

NASA map sees Earth's trees in a new light

A Nasa-led science team has created an accurate, high-resolution map of the height of Earth's forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth's vegetation. read more..

Babies know what's fair

"That's not fair!" It's a common playground complaint. But how early do children acquire this sense of fairness? Before they're 2, says a new study. "We found that 19- and 21-month-old infants have a general expectation of fairness, and they can apply it appropriately to different situations," says a psychology graduate student. read more..
