Summary

Story summary

Australian Institute for Bioengineering and Nanotechnology (AIBN) researchers report neurons derive energy from fats, not glucose, challenging models.
The DDHD2 gene enables neurons to break down fats; mutations cause energy failure.
Fatty acids are crucial for neuron function; absence triggers neural decline, including HSP54.
A separate study links brain fat deposits to Alzheimer's disease; DGAT2 targeting could restore microglial function.
