Science Friday: 3-D Map of Objects in Earth’s Orbit | The Bottom of the North American Continent may be Peeling Off | Words On The Brain – A Semantic Map of the Cortex

objects in earth orbit

Ever wondered just how full the skies are? This real-time 3D map shows you objects currently in Earth orbit — from satellites and rocket bodies to good old space debris. It’s pretty busy up there.

Created by James Yoder, Stuff in Space is based on orbit data from Space-Track.org that’s updated every day.

Chunks of Earth’s Mantle Are ‘Peeling Off’

 

An odd phenomenon may explain why the Southeastern United States has experienced recent earthquakes, even though the region sits snugly in the middle of a tectonic plate and not at the edges, where all the ground-shaking action usually happens.

This seismicity — or relatively frequent earthquakes — may be the result of areas along the bottom of the North American tectonic plate peeling off, the researchers said. And this peeling motion is likely to continue, leading to more earthquakes in the future, like the 2011 magnitude-5.8 temblor that shook the nation’s capital.

Words On The Brain: A Semantic Map of the Cortex

By Neuroskeptic | April 30, 2016 11:15 am

In a new Nature paper, Berkely neuroscientists Alexander G. Huth and colleagues present a ‘semantic atlas’ of the human brain. Huth et al. have mapped which brain areas respond to words, according to the semantics (meanings) of each word. It turns out that these maps are highly similar across individuals …
