A Chicken’s Remarkable Image Stabilization Ability

By Anupum Pant

Background

I saw this Smarter everyday video, made by Destin, a very long time back and I remember very well that I had stored it away in my notes somewhere to share it with you guys in the future, but it was nowhere to be found. As time passed, I totally forgot about it. Just yesterday, while writing about how chicken heads saved Switzerland from rabid foxes, there was a sudden flash in my mind and I recalled having seen Destin’s video (I don’t know how that happened. Brains are amazing). I’ve attached it below for you to see.

In the video, Destin demonstrates how chickens have an amazing ability which enables them to keep their heads perfectly stable. It is just one of the many ways birds are better than humans. Irrespective of how their body moves, their head remains perfectly still in a way that their eyes are able to see a very stabilized image.

It is interesting to note that it isn’t just chickens who have this ability. Owls and a couple of other birds have this built-in too. In fact, cats can do it to some extent too, but chickens and owls are definitely better at it.

NASA, before it had sent humans to space, conducted a similar experiment with owls with an expectation that they would learn something that’d help them reduce trauma to humans in space. This is how an owl was moved around by them in every axis possible. It passed every test they threw at it. Look at it go…

The Vestibular Ocular reflex system

Most vertebrates have this device inherently built into their inner ears which has three tubes (probably to detect movement in all three dimensions). The biological device is called the Vestibular system. This is what it looks like. You can clearly see the three semi circular tubes coming out.

These three tubes are filled with a fluid which moves around when the head moves. As the fluid moves, it pushes something called a cupula and converts mechanical movement into an electrical signal. The signal is sent to the brain to process.

As a result, the brain sends back information to the eyes and moves them in the opposite direction. That is how your eyes are involuntarily able to stay focussed at a single point even when you move your hear. This is called the Vestibular ocular reflex system.

But the chicken’s eyes don’t move, so it isn’t probably correct to call it an ocular reflex. Instead their whole head moves in the opposite direction to their body movement. Thanks to the vestibular system. I’m not totally sure, but this could have something to do with righting reflex – the same thing that makes cats turn the right side up when they fall. Please help me with this in the comments section if you know more…

Chicken steady head cam

Using the same amazing biological image stabilization technology that was at his disposal, a youtuber decided to tie a camera to the chicken’s head to make a steady headcam. I think it’s an amazing idea for R&D.

Soviet Man Who Survived a Particle Accelerator Beam

By Anupum Pant

Not even the world’s greatest researchers are too sure about what really happens when you put your hand in front of a particle accelerator beam.  And yet, we know what happens (not always) when you stick your head into a particle accelerator.

The Accident

That is because a Russian scientist named Anatoli Petrovich Bugorski, in the year 1978, working at U-70 synchrotron at the Institute for High Energy Physics in Protvino, accidentally put his head into a particle accelerator while checking for a dysfunctional part in the equipment. His head came in the path of a high-energy proton beam moving at a speed that was just slightly less than the speed of light. The beam entered his head from the back and came out from somewhere around the nose. Only he knows what he exactly saw when that happened. Apparently, he saw a very bright light, a light brighter than thousand suns and felt no pain.

Post Accident

The left part of his face, where the beam had passed, started swelling beyond recognition and people were certain that the man would soon die due to radiation poisoning. The proton beam had travelled through his head, burning all the living tissue in between and caused the skin at entry and exit points to peel off. The beam had passed a part of his brain and had burnt a considerable amount of brain tissue too. The picture below shows the path where the beam travelled and burnt all the living tissue.

Miraculously, he survived after being exposed to about 200,000 rads of radiation dose (enough to nearly kill the toughest bacterium)! Hell, even 500-600 rads are lethal for human beings. That was mostly because the beam was very thin and only a fraction of tissues out of the whole body that  got exposed to the beam were severely damaged, it left most of the remainder of the body exposed at pretty low levels of radiation.

Not just that, his mental performance showed no signs of degeneration. He even went on to complete his Ph.D after this accident and still lives a fairly healthy life. However, the accident did leave him with a dysfunctional left ear and a permanently paralysed left side of his face. Notably, the left side of his face became frozen and also never aged. At the same time, the right side of his face ages normally.

At that time this accident was buried by the Soviet Union and was branded as top-secret. It was only a couple of years later the whole world came to know about this.

Anatoli remains to be the only person to have ever done this. Most shockingly, he also survived it and still lives a fairly healthy life today.
