Tiger Cubs are born Blind.

Tiger cubs are born blind. Yup, that’s true. They remain dependent on their mother for the first two months. The tiger cub’s eyes open around six to twelve days from their birth. However, they attain full vision after a couple of weeks.

At this stage, they are completely vulnerable to every other predator. That is part of nature’s balancing act, which allows a fair chance to others against the apex predator. The tigress is solely responsible for the protection and care of the cubs that’s why she leaves them only for short periods.tiger-cubs

Tigeress usually give birth to around seven cubs, but the average size of its litter is three. The tigress spends a lot of time at the late stages of pregnancy searching for a safe birthing place. Tigress is overly cautious when caring for young cubs. For instance, she will immediately move cubs to a new place if the surrounding area gets disturbed or threatened.

The tiger cubs start following their mother for casual walks or on drinking trips only after two months of age. Tigress will spend nearly 70% of their time nursing and caring for their cubs. The cubs spend most of their time playing with their siblings and they become independent after seventeen to twenty-four months of age.

So now we know that Tiger cubs are born blind and how tigress takes care of them. Also, we know how nature plays its balancing act to allow a fair chance to others against the APEX predator. 🙂.

A Human Hair equals 90,000 DNA strands.

You could fit 90,000 strands of DNA side by side in a single adult human hair. Yup, that’s very much true. DNA strand is a very thin molecule averaging only about two nanometers in width. That is roughly two billionths of a meter.

When you compare the width of DNA with your hair then it is very thin. As given above, DNA double helix is about 2 nanometers wide while the width of average adult human hair is around 180 micrometers. This means that an average human hair roughly equals 90,000 strands of DNA kept side by side.

DNA strand is also a very long molecule. For instance, if we lay out every DNA strand (in a cell) end to end, it would measure around 2 meters. So, it is nearly impossible to pack it inside the nucleus of a cell. But, the incredible thinness of the DNA strand allows it to be very tightly packed.

So now we know that 90,000 strands of DNA can be packed inside a single human hair. Also, we now know that a DNA strand is not only thin but also very long (i.e. about 2 meters long). 🙂.

Stars Are Merely Luminous Balls of Gases.

Stars are mostly huge balls of hot gases such as hydrogen and helium. These gases stick together using their own gravity. These huge balls of gases produce light and heat from the energy released by the thermonuclear fusion of hydrogen and helium.

Some stars shine more brightly than others. Their brightness depends on factors such as how much light stars put out and their distance from earth. The nearer the star the brighter it is. The nearest star to the Earth is the Sun, thus the brightest.

Stars are building blocks of our universe and their life cycle spans billions of years. These luminous balls of gases helped ancient explorers navigate the seas and now help modern-day scientists navigate the universe.

So now, we can say that stars are nothing but merely luminous balls of hot gases. Also, we now know that these stars not only make our night sky beautiful but also helps us in various ways. 🙂.

How does a scientist’s brain work?

Curiosity is a characteristic feature of a scientist’s brain. It makes scientists think in specific ways and observe patterns and natural processes. The brain of a scientist has a natural urge to learn how things work in this world. This urge to know every aspect makes their brain the most creative mind.
how-does-scientist-brain-work
The scientist’s brain can harness the power of curiosity to investigate every aspect of this observable world. For example, a scientist can deduce many things after seeing a half-filled glass. He can say that one-half of the total volume of glass is occupied by water, and the other half by air. In addition to this, a scientist can deduce the composition of water and air present in the glass and so on.

Thus, we can say there is no limit to a scientist’s brain. Also, this article was not meant to be serious but what can I do, this is how a scientist’s brain works 😉. So that is all for now and meet you in my next article. Keep Reading, Keep Exploring, and Keep Sharing your Knowledge, and above all BE CURIOUS. 🙂

Blueberries aren’t actually Blue.

Blueberries are not actually blue, but deep purple, which is the color of anthocyanin, a pigment that is especially rich in blueberries. Anthocyanins are very useful in combating inflammation. A good rule to follow is, the darker the berry, the more anthocyanins are present. Continue reading Blueberries aren’t actually Blue.

Ice is a cooler version of water.

Water turns into ice when it cools down to zero degrees Celsius (or 32 degrees Fahrenheit). So, we can say that “ice is a cooler version of water” :D. Ice often forms on lakes, rivers, and the ocean in winters. It occurs in different forms such as frost, snow, sleet, and hail.

science_jokes

When the temperature of the water gets close to the freezing point (i.e. zero degrees celsius), water molecules begin to expand. In a small space, these expanding molecules can create a lot of pressure. This is why when water freezes in a crack in a rock, the ice can eventually break the rock apart (using the pressure of expanding molecules). Thus, it plays a very important role in the process of weathering.
