Fruit flies are the GOAT of biology!

And they just proved it again.

Fruit flies have been a key model organism in genetics for over 100 years. 🪰 became famous in labs because:

1️⃣ it reproduces extremely fast 2️⃣ the genome is relatively simple 3️⃣ mutations are easy to observe

A surprising number of fundamental discoveries about inheritance came from experiments with 🪰

The researchers built a virtual fruit fly controlled by a simulated brain. The brain model is based on the real fly connectome - about 140k neurons and ~50 million synapses.

They connected this brain to a physics-based digital body, creating a loop:

world sensory neurons brain activity motor signals body movement

And the digital fly actually behaves like…...... fly

It can:

walk toward food using taste cues groom itself when "dust" accumulates start feeding when sugar receptors activate

The neurons are simplified. Only a few behaviors exist. Real flies are far more complex.

But the concept is SOOO powerful - take a real brain and let it control a body in a simulated world.
