You must know that our body cells are easily outnumbered by the bacteria in our body. When we breathe out, we include some of these bacteria in our breath. A recent study has found that people can be identified by these bacteria they breathe out. In other words, we have our own exclusive bacterial clouds pouring out of our mouths.
Mankind is ready to take the next giant leap as plans on establishing human settlement on Mars are being made. This mission, known as “Mars One”, will send fully trained human crews to Mars by the year 2026.
The light that form rainbows undergo both refraction and total internal reflection. There is an average angle of about 41° between the light rays that enter a water droplet and the light rays that emerge from the droplet after undergoing the above processes. Different colors are experienced because different wavelengths are refracted at different angles. These emerging light rays we receive are therefore shaped like an arch.
Why does the rainbow take the shape of a curve/semi-circle?
If you were asked what color the Sun is, most of you will say it’s yellow, red or orange. But in the outer space, Sun appears to be white. The Sun looks yellow to us, because the white color gets scattered while passing through the atmosphere.
Can you believe that as little as 25% of an original liver mass can regenerate back to its full size? Liver is the only human internal organ that has this ability to regenerate.
When doing sports and exercises, we lose a lot of fluid and electrolytes like sodium, potassium, magnesium, calcium, and chloride through sweating. If a person drinks water at a situation like this, it can be really dangerous since it is the quickest way to dilute the body’s sodium concentration even more. Most sports drinks contain water, electrolytes, and some form of sugar to provide a small source of energy to help maintain blood sugar and fuel working muscle. So to avoid of dehydration plain water is not good as sports drinks.
Sportsmen and women usually prefer drinking sports drinks before and after their events rather than drinking plain water. What is the reason for this?
Starting at about age 40, people typically lose about half an inch each decade. This is due to our spine losing bone density, and the gel-like disks that separate each vertebra getting worn down and thin as we age.
Ever wondered how big the salt content of the sea is? Well, this might give you an idea. If we take out all the salt from the sea and pile them on the ground, there will be enough salt to cover all the continents to a depth of nearly 500 feet.
Some desert beetles have a clever way of finding water in their parch habitats. They are known to collect water by condensing fog into droplets on the ridges of their backs. Inspired by these beetles, researchers have developed a bumpy material made out of glass and plastic, mimicking the beetle’s back. These materials are planned to be used in creating a self-filling water bottle in the nearby future.
The frequencies of thundering sometimes come close to the natural frequency of the windows, causing them to resonate and vibrate. When the frequency of thundering is exactly the natural frequency of the windows, the vibrations might be so strong as to break the glass of the windows.
Thundering sometimes causes windows to shudder. How does this happen?
Have you seen the rattling of tree leaves above a fire? This happens due to the convection current of the heat that is generated by the fire. The air around the fire gets heated and travels upward, hitting tree leaves above and causing them to rattle.
Saccharin, a widely used artificial sweetener, was a discovery which took place because one of the scientists forgot to wash his hands and accidently tasted the chemicals that were on his hands! Saccharin is hundreds of times sweeter compared to natural sugar and better for people with diabetes due to its low calorie content.
A wasp species called Polybia paulista has been discovered to contain a powerful cancer fighting ingredient called MP1 in their venom. MP1 selectively destroys cancer cells by interacting with lipids that are abnormally distributed on the surface of cancer cells while avoiding healthy cells.
Manioc contains poisonous cyanogenic compounds. When boiling, the cyanide in these compounds get cleared out as Hydrogen Cyanide gas. When the lid is closed the gases don’t escape the food, leaving it still poisonous.
Why is it not good to cook/boil Manioc with the lid of the cooking bowl closed?
Do you know why the manholes in the streets are made in a circular shape? This is to keep their lids from falling inside. If they were built in square shape, there’s a possibility of the lid to fall in as the diagonals are longer than the length of a side.
Walking regularly is the foundation for good health. It reduces your risk of heart disease, stroke, asthma, osteoporosis and diabetes, lowers bad cholesterol and is a great workout for the heart and circulatory system.
Have you wondered why far away mountains tend to look blue? This happens because the light rays that pass through atmospheric particles often get scattered. The elements in the atmosphere scatter blue color much more efficiently. This is the same reason for the sky to look blue.
