This is known as one of medicine’s most incredible moments.
In 1922, at the University of Toronto, scientists went to a hospital ward with children who were comatose and dying from diabetic keto-acidosis. Imagine a room full of parents sitting at the bedside waiting for the inevitable death of their child. The scientists went from bed to bed and injected the children with the new purified extract - insulin. As they began to inject the last comatose child, the first child injected began to awaken. One by one, all of the children awoke from their diabetic comas. A room of death and gloom, became a place of joy and hope. Thank You Dr. Banting and Dr. Best!

Wow! 1922! I would have thought a lot earlier!

Most of physical reality is invisible to us, according to science.

95% of the cosmos may be forever beyond our ability to sense or detect it.

Our eyes detect light within a narrow range of 380-770 nanometers, while our ears register sound between 20 Hz and 20 kHz.

Beyond these limits, ultraviolet and infrared light remain invisible, and ultrasonic or infrasonic sounds go unheard. Yet, these unseen and unheard frequencies exist all around us, influencing nature and our bodies in ways we may not realize.

From radio waves to deep-sea whale calls, countless signals move through the air and environment, unnoticed by human senses. Modern technology, like infrared cameras and ultrasonic sensors, helps bridge this sensory gap, revealing an unseen world filled with vital information. Still, what else might we be missing?

For example, neutrinos are abundant subatomic particles that pass through almost everything — including our bodies — and only very rarely interact with matter.

And we haven't even started to talk about things like dark matter and dark energy.

What is the biological phenomenon responsible for the gradual loss of muscle mass, strength, and function as we age? This is known as Sarcopenia!
Sarcopenia refers to the progressive loss of skeletal muscle mass and strength due to aging. The impact of this condition can be severe, depending on the individual.
How to prevent Sarcopenia?
Stay Active: If you can stand, don’t sit—if you can sit, don’t lie down! Movement is key to preventing muscle loss.
Encourage Movement in the Elderly: When an elderly person is sick or hospitalized, avoid encouraging them to rest or remain in bed. Help them walk, unless they are too weak to do so. Lying in bed for just a week can cause a 5% loss in muscle mass, and seniors often cannot fully recover this loss.
Sarcopenia is more concerning than osteoporosis: With osteoporosis, the primary risk is falling, but sarcopenia not only affects quality of life but also contributes to high blood sugar due to reduced muscle mass.
Idle muscles lead to faster muscle loss: Muscles in the legs deteriorate quickly when not used. Sitting or lying down limits leg movement, weakening muscles. Activities like walking, running, and cycling are excellent ways to build and maintain muscle mass.
Aging Starts from the Feet Up! Keep your legs active and strong as you age. If you don’t move your legs for just two weeks, you’ll lose the strength of a decade! Regular exercises like walking and cycling are vital for maintaining muscle strength.
The feet support the entire body’s weight, making them critical for mobility. So, walk every day to maintain strength and mobility.
 
Want to understand our place in the universe?
It takes our Sun 250 million years to orbit the Milky Way.
Ultimately, the Milky Way is about 100,000 light-years across and 1,000 light-years thick. Our solar system is located about 26,000 light-years away from the center of the galaxy.
If that's not impressive enough, our star is just 1 of the 200 billion stars in the Milky Way. As such, scientists estimate that there could be as many as 3.2 trillion planets in our galaxy.
And keep in mind, these are just the numbers for our own tiny galaxy. According to NASA, there are about 2 trillion galaxies in the observable universe.
 
A middle school student conducted an eye-opening science project that revealed some surprising findings. The student compared the cleanliness of ice from fast food restaurants to toilet water. The results showed that in about 70% of the cases, the ice was dirtier than the water found in a toilet. This unexpected outcome surprised many people, as one would typically assume that ice used in food service would be kept clean and safe.
The student's project involved collecting ice samples from several fast food restaurants, as well as toilet water samples for comparison. Using standard methods to test for bacteria and other contaminants, the student discovered that the ice often contained more germs than the toilet water. This information highlights potential problems with how ice machines are cleaned and maintained in these establishments.

"Sharks are immune to every disease, including cancer".

And, yep, researchers are indeed studying sharks with the hopes of being able to treat/prevent cancers.

Robert Knox's book "An Historical Relation of the Island Ceylon" is a source of information about colonial Sri Lanka. Today people quote from it to show how resourceful Sri Lankans were yet how foolishly they acted about their own culture.
Robert Knox's life in Sri Lanka also gave the idea for Robinson Crusoe.

Indike, can you say more about that?

This is a hard question to answer. :) What some people talk about today is that Robert Knox reported the locals to have certain virtues but they don't seem to have them today. e.g. "Of all Vices they are least addicted to stealing, the which they do exceedingly hate and abhor, so that there are but few Robberies committed among them."

Anyway, having spent his time as a prisoner to a great extent, he seems to have lost faith in the locals. But even in his not so friendly description he appreciates certain qualities. So some people quote those and lament the deterioration of culture.

Others use the text to insult the locals, their own kind, of how bad the society was during that time.

However what's said in the text is partially correct in the sense that he did not understand the people properly being a prisoner, but he describes things as he saw them.

Here's a full text of it, which is in pdf format, you can read a little bit.

I actually found the PDF and read through a bit of it. But I was looking for an executive summary, so thanks for that, Indike!

Music on hold was created by Alfred Levy, an inventor, factory owner, and entrepreneur. In 1962, Levy encountered an issue with the phone lines at his factory: a loose wire was touching a metal girder of the building. This created a situation where the building acted as a giant receiver, allowing audio signals from a nearby radio station to be transmitted through the loose wire. As a result, callers would hear music while they were put on hold.
