Scientists at Harvard University, working with Google AI/machine learning experts, have published an amazing study of a one cubic millimetre piece of human brain. (The piece was excised during a medical procedure).

The sliver of tissue, ~3 mm long, was sliced into over 5,000 thin sections and each one was scanned with an electron microscope. The images were then analyzed with Google’s machine learning programs (AI) to piece together a detailed 3-dimensional picture of the cells and their connections.
The tiny fragment contained 57,000 cells and 230 mm (9 in) of fine blood vessels. It had thousands of neurons and nearly 150 million synapses (the major connections between neurons).
The electron microscope images alone occupied 1,400 terabytes of computer memory. To put this in perspective, a typical large external hard drive today stores 20 terabytes. It would take 70 of these hard drives to store the data. But the whole brain is one million times this volume. Scaling up, we would need 70 million hard drives. At just $US300 each, this would cost 21 billion dollars, quite aside from the power to run them. And that’s just for one copy.
The researchers found things that have not been seen before. As one of the co-authors who helped lead the research, Jeff Lichtman, remarked to the Guardian,
“We found many things in this dataset that are not in the textbooks. We don’t understand those things, but I can tell you they suggest there’s a chasm between what we already know and what we need to know.“
We have a long way to go before we understand how the brain works. Indeed, we are “fearfully and wonderfully made” (Psalm 139:14).
It is getting harder and harder for biological scientists to cling to evolution and random chance and deny intelligent design for what they can now observe. Since the discovery of DNA and the electron microscope that revealed complex machinery even in the simplest cell, the demise of evolution as the cause of life on this planet was sealed.
“For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.” Romans 1:20-23
