Do flies over-generalize memories like PTSD sufferers?

No two cakes smell identical, yet we are still able to recognise the general aroma that promises pleasure. Ayse Yarali from the Leibniz Institute for Neurobiology, Germany, explains that this ability to generalise a previously ...

Shocked gas in galaxy collisions

NuSTAR finds new clues to 'chameleon supernova'

"We're made of star stuff," astronomer Carl Sagan famously said. Nuclear reactions that happened in ancient stars generated much of the material that makes up our bodies, our planet and our solar system. When stars explode ...

Researchers dial in to 'thermostat' in Earth's upper atmosphere

A team led by the University of Colorado Boulder has found the mechanism behind the sudden onset of a "natural thermostat" in Earth's upper atmosphere that dramatically cools the air after it has been heated by violent solar ...
