You must all have dreamt in your sleep about places you want to go. Just like us, animals do that too. This theory was confirmed after a study conducted by the University College of London on mice by examining their brain activity using electrodes.
Recent studies have shown that by consuming your food slowly, you can actually fill yourself up with less food. So if you want to stay thin, eating slowly might help, since you would be eating less.
“Science is global. Einstein’s equation, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it.” – In remembrance of Dr. Abdul Kalam, Renowned Scientist and Former President of India.
Burn patients have a lot of damaged tissue that needs regrowth and should go through a long and energy consuming recovery process. A high protein diet is given to them since additional protein is needed to rebuild lost and damaged tissues. Otherwise, the patient’s muscles will break down to produce extra energy for the healing process.
A high protein diet is given to burn patients at hospitals. Why is this?
Dogs are often observed panting with their tongues sticking out. They do so, as it helps them to regulate their body temperature. Unlike humans, dogs don’t rely on sweat to cool themselves. The moisture on their tongues evaporates and gives them a cooling effect.
Do you know that the pressure generated by a water column of 10 meters is equal to the pressure created by the whole atmosphere? That means, if you dive 10 meters underwater, you will experience a pressure that is equal to twice the normal atmospheric pressure.
You must’ve seen numerous times the pellicles left by snakes lying around in the environment. But does it ever come across to you that we humans do a similar thing, although not very significantly? Little by little, the average human being sheds about 18 kg of skin in a life time.
When traveling between two mediums, light beams bend, due to the change of velocity in the two mediums. This is called refraction. The light rays that come from water travels from a more dense medium to a less dense medium when entering air (in which the velocity is higher), causing the light beams to bend slightly outward, towards the water surface. As a result, the depth of the ponds appears elevated, causing the observer to observe a depth that is considerably lower than the original depth. However, only the light beams that meet the water-air surface angularly get refracted.
When looking into ponds and swimming pools from the outside, they appear to be a lot less deeper than they actually are. Why is this?
Inspired by the method corals use to make coral reefs using dissolved CO2 in the water, a scientist has created a new way to make cement using CO2 as a raw material. The cement manufacturing process today produces around 5% of global carbon dioxide emission, holding a vast threat to the environment.
Did you know that, 40 light years away from us, there’s a planet called “55 cancri e” which is twice the size of earth and consisted 1/3 of diamond? It’s made up mostly of carbon and has a surface temperature of 2100 °C, which make perfect conditions for creating diamonds.
Isn’t it bizarre that there a type of lizards called Horned Lizards (Phrynosoma genus) that shoot blood from their eyes as far as up to 1.5 meters, in order to protect themselves from predators. The blood is mixed with noxious chemicals, which come from the venomous ants that these lizards consume.
When people travel in the upper deck of the bus standing, the center of gravity of the system (bus and the passengers) gets elevated to a higher point, making the bus unstable. Because of this, the bus has a higher risk toppling over when taking turns.
People are advised not to go standing in the upper deck of a double decker bus. Why is this?
Have you ever wondered how many tiny bacteria are living in your body? It’s been estimated that there are 10 times as many bacteria cells as the human cells in the body. Scientists have come up with an approximate number for the human cells an average person has, and that’s 37.2 trillion. That multiplied by 10, we get 372 trillion! So there are 53100 times as many bacteria in a single person’s body as the global population.
You would be surprised to hear that human saliva contains an extremely powerful painkiller. This compound, called Opiorphin, is 6 times more powerful than the common painkiller Morphine.
Do you know that the Seahorse tail has become a special interest to robotics researchers, because of its flexible yet strong nature, and its ability to snap naturally back into place once it’s been twisted and deformed? They believe that studying this brilliant structure of the Seahorse tail and understanding its mechanisms could be helpful for modern day robotics applications in numerous fields.
In highland areas, the atmospheric pressure is low. Due to this, the boiling point of water drops by several degrees, making the water boil before its temperature reaches 100 °C. Therefore the maximum temperature the vegetables come in contact, is lower than that at sea level. Therefore they take longer to cook.
When boiling vegetables, they take longer to cook at mountain tops than at sea level. Explain this statement.
The solar system is a pretty bizarre place. Did you know that snow-like metal falls in Venus? Just like there are snow-capped mountains on earth, there are metal-capped mountains on Venus, and it is mostly consisted of heavy metals.
