No Implants Needed For Precise Control Deep Into the Brain

An anonymous reader quotes a report from IEEE Spectrum: In April, Guoping Feng and colleagues at MIT, along with [Karl Deisseroth, a neuroscientist and bioengineer at Stanford University] demonstrated a minimally invasive optogenetic system that required drilling a small hole in the skull, then being able to control opsin-expressing neurons six millimeters deep into the brain using blue light. This approach…

Why are skies so red over the U.S. West this week?

The Tunguska explosion could have been caused by an asteroid that still orbits the sun

On a cool summer morning in 1908, a fireball appeared over northern Siberia. Eyewitnesses described a column of blue light that moved across the sky, followed by a tremendous explosion that leveled trees across more than 2,000 square kilometers. The explosion is consistent with a large meteor strike, but to this day, no evidence of a crater has been found. Now…
