Why does the voice change with helium?

When you inhale ambient air, your vocal cords vibrate in "normal" mode.

However, helium has a lower density, around 7 times lower than air. As a result, the vocal cords are less strained and vibrate at a higher frequency. The voice becomes higher and more squeaky.

And if you inhale a heavy gas, such as sulfur fluoride, which is five times heavier than air, even a child will start talking in a bass voice.

Super Absorbent Polymer: poly-acrylamide polymer crystals are able to absorb up to 200 times their volume of water. Here seven small spheres, approximately 4mm in diameter, were immersed in water for three hours, after which they were slightly more than 23mm across. The final gel sphere is more than 99.5% water- and they bounce!

Google developing a Starline system for 3D video calls with effect of total presence

The goal of the project is to achieve the effect of nearly total presence of the interlocutor to your video calls. The callers, who are thousands of kilometers apart, communicate as if they are speaking through glass, all the while being in the same room.

This system comes with several cameras, sensors and a large display inside.

The project combines three key technologies – the creation of a 3D model of the caller, data compression during transmission in real time and visualization of 3D images and voices on other end of the call.

A Scorpion finds himself at the bank of a river and realises he cannot cross.

He approached a Frog who was aslo by the riverbank and asked him for assistance in crossing.

The Frog instantly replied saying "No, you're a scorpion you'll try and kill me as we cross".

The scorpion replies by saying "Why would I strike you whilst crossing? I'd die along with you!"

On that note the Frog agreed to help the Scorpoan cross the river..

So the Scorpion jumps onto the Frogs back and they begin to cross.

Hallway across the river, the Frog feels the killer blow of the Scorpians sting.

The Frog, with what energy it had, knowing both we're doomed said to the Scorpion "Why did you do that? now we'll both die".

The Scorpion simply replied by saying.. "Because I'm a Scorpion."

We Are Who We Are

Nephrosclerosis (Wrinkled Kidney) is a pathological condition caused by the death of nephrons, their replacement by connective tissue with an increase in renal failure.

The brain, like nearly the entire body, is more than half water

Roughly 75% of the brain is "built" of water. But, if we try to dry it out, we get a 60% fatty residue.

That's why some scientists call the brain cheese - it's mostly made of water, but the dry residue is fat🧠

Our lungs have one interesting superpower.

More specifically, the entire respiratory system.
Breathing is the only process that can operate both automatically and be controlled by humans.

What does this mean?
Well, you've noticed that we don't have to take every breath "manually." However, at the same time, we can safely perform some Indian breathing exercises.

Wouldn't it be easier to give control over this process completely to the brain🤔
Absolutely not!
After all, in addition to how to breathe, the lungs are also involved in the process of sound formation. Yes, and breathing sometimes needs to be regulated manually.

▫️ Mortality in Russia in 2021

According to the latest United Nations data, Russia in 2021 ranked sixth in the world both in the total number of deaths (2.459 million people) and the mortality rate (17 deaths per 1,000 inhabitants). By the way, it is interesting that the leaders are not African countries, and the European countries (probably due to the high mortality rate of elderly against the background of covid): the first 5 places were taken by Bulgaria, Monaco, Latvia, Serbia and Lithuania. And we are 6, and Ukraine is 7

What is really frightening is mortality of men of working age. Of the men who survive to 15 years do not reach 50 182 out of a thousand, and up to 60 - 340 out of a thousand, that's 28 and 22 places respectively (out of more than two hundred). The places seem to be not as bad as in the previous case, but here we are ahead of even most African countries. We shared our place with Burkina Faso in the male mortality rate from 15 to 50, and from 15 to 60 with Cameroon and Guyana. We were be
