Brain tissue kept alive for weeks with new microfluidic device


A new microfluidic device can keep tissue cultures functional for weeks on an artificial membrane

Mutation links bipolar disorder to mitochondrial disease


ANT1 mutations found in bipolar disease that affect mitochondria lead to hyperexcitable serotonergic neuronal activity in the brain.

Flies use fecal deposits as pheromones


Bioluminescence imaging of fly brains reveals neurons sensitive to fly poo laced with pheromones (you can see the fecal “landmark” in the dotted circle). Need we say more?

Brain wave synchrony can predict memory age


The degree of neuronal synchrony between the anterior cingulate cortex and the hippocampus during recall is an indication of memory age (in mice).

Supermassive black holes still dark and mysterious


For the first time, scientists have measured the strength of magnetic fields near supermassive black holes and something doesn’t add up.
