HOW CATS SEE AND TOUCH THE INVISIBLE

 

Did the title surprise you? Well, don’t be, for nothing shows that cats can see spirits. In this context, the “invisible” are visible things hidden from sight because of darkness. So how do cats find their way and even hunt comfortably in the dark? The secret lies in their whiskers, or vibrissae.

Cat whiskers are super sensitive to pressure, even air pressure. The slightest movement of air is noticed by these whiskers. How are they so equipped?

Cat whiskers are joined to tissues that are connected to so many sensitive threads called nerves. These nerves connect directly to the brain of cats and act as direct messengers to the brain. Since the connection process between the brain and the whiskers is almost direct and involves soft sensitive tissues and cells, the brain can easily detect even the things that pass by the whiskers.

Cat whiskers have a lot of functions that are not even fully understood. They can sense the movement of animals and obstacles around because of air pressure, even though the cat cannot see these things in the dark. Also, cats can use their whiskers to measure the size of a hole before they pass through it. How spectacular!

To help us fully understand how sensitiveness to air pressure enables cat whiskers to notice obstacles and animals, consider this illustration. If you close your eyes in a dark room and try to walk around very slowly, you will often notice you are close to the wall even before you hit it. You will be even more sensitive to obstacles if you blindfold yourself and try to walk outside. This sensation that makes us stop just before an obstacle is as a result of air pressure.

You see, even though you may not notice it, your skin relies on the movement of air flowing past it in order to notice obstacles. So when there is something blocking the airflow towards it or away from it, your skin takes notice of this change and your brain interprets it as an obstacle. And if something is moving towards you or if it passes in front of you, it pushes air according to its overall size. That movement of air is the science of air pressure. The amount of moving air you feel also tells you how big or how small an object close to you is.

According to scientists, if the whiskers of cats are cut off, the cats become unable to function for some time. What a wonder cats are adorned with!

GECKOS POSSESS PINS

“What for?” you may ask. After all, they could hurt someone or something, or they could even be hurt by their own pins. Amazingly, the pins are too tiny, soft and flexible to even hurt anyone or anything. That is why, if you’ve ever had a wall gecko climb on you, you would never see any scar on your body. The information you are about to read reveal the very reason gecko lizards can climb and walk on almost any surface. It was discovered that gecko lizards possess extremely tiny hairs under each of their feet. These hairs rise and flatten, and can be detached easily from surfaces because of the direction, or angle, in which they grow. These hair-like pins, more appropriately called setae , also have several smaller parts on each of them, making them look like ceiling brooms.  The tinier hairs, which are more of fiber, are called spatulae . The setae are made of keratin_ the same material human fingers are made of. Due to their structure, size, mass number and the material with ...

THE EXTRAORDINARY ABILITIES OF HOUSEFLIES TO ESCAPE DEATH

Does it surprise you to think that an animal can escape death, talk less of a housefly? Of course it shouldn’t. Remember the first science post on this blog that explained how fireflies escape danger, thanks to their wing speed and exceptional flying skills. Like fireflies, houseflies obviously have wing speed and flying skills, though they flap their wings at a much lesser speed than fireflies, that is 80 times per second, compared to fireflies that flap theirs 200 times per second. However, this post is not about speed or flight skills. This is about surviving a death trap. So just picture the following scenario. You used a local African broom to hit a housefly so that it doesn’t fly anymore, but you still manage to leave it alive so that you can punish it. You carry a condemned water bottle and fill it almost to the brim with water. After that, you picked up the weak fly, put it inside the water bottle (maybe even use a small stick to push the fly down the liquid to drown it sin...

LITTLE SECRETS IN THE WINGS OF BUTTERFLIES

  Considering the kind of environment in which butterflies flourish, it is expected that they would find flying around difficult. This is because their wings are so soft and light that even little dust particles or water droplets can make their wings heavy for them. Surprisingly, though, the butterflies are mostly observed clean and dry. What’s the big secret? Let’s consider the Giant Blue Morpho butterflies . Like other butterflies, these Morpho butterflies have wings that look flat and feel extremely smooth. However, research confirms that they are structured in layers, in step-by-step pattern. In addition to the step-by-step arrangement, each layer has grooves or open lines, just like gutters dug in the ground. This efficient design makes it possible and easy for any dirt or water moisture to fall away. To understand this more clearly, think of this illustration: What could happen if a small ball the height (or diameter) of a CD is kept on top of roofing sheets that are ab...
