All mammals get goosebumps. When your hair stands on end, tiny muscles contract at each hair’s base which distorts the skin to create goosebumps. This process is called piloerection and is present in all mammals. Hair or fur is used to trap an insulating air layer.
100 Mind-Blowing Present Facts
NASA believes liquid water flows intermittently on present-day Mars.
Theodore Roosevelt had a pet hyena. Its name was Bill, and it was a present from the Ethiopian emperor. Roosevelt was famous for his many pets, including a one-legged rooster, a badger, a pony, and a small bear.
Marie Curie’s belongings still have radioactive residue in the present day. Marie Curie’s contributions to science had her named by many as the mother of modern physics. One of the works she was most known for was her study of radioactive materials and the discovery of elements such as polonium and radium. However, her research took a toll on her health. Radioactive exposure not only led to her death due to aplastic anaemia – but her clothes, furniture, and books remain radioactive to this day. Now, over a century later, her notebooks have to be stored in a lead box, as they will still be radioactive for another 1,500 years.
The Titanic film runs for as long as the ship sunk. Minus the present-day scenes and opening/ending credits, Titanic is 2 hours and 45 minutes long – which is also the time it took for the ship to sink in 1912. Additionally, the collision scene lasted 37 seconds, which is also how long the ship collided with the iceberg in real life.
The chicken is the closest relative to the T-Rex. Recent studies have now accepted that prehistoric dinosaurs have more in common with present-day birds than they do with reptiles. Research has found that their genetic makeup is shared more with chickens and ostriches rather than lizards.
The flashes of light when you rub your eyes are called phosphenes. This phenomenon allows you to see light without any actual light source present. This occurs due to many possible sources like magnetic stimulation, or random firing of cells in the visual system.
About 80,000 plant species are edible. However, in the present day, only 150 species are regularly cultivated. 30 of these products make up 95% of the human’s usual calorie and protein intake.
There are pink lakes in Australia. On the western coast of Australia, a pink lake called Lake Hillier can be found. It gets its colour from the algae present in the area which mixes with the lake’s salt content to create a pink colour. Despite the vibrant pink colour, it is safe to swim in this lake. The Russians arrived 12 days late to the 1908 Olympics. This was mainly because they were following the wrong calendar. After this incident, the catholic nations mandated the use of the Gregorian Calendar.
The human body is the cause of metallic smells found in coins and other metals. Upon contact with some metals, 1 Octen 3 One is formed as the result of the decomposition of oil present on the skin. This is what causes the metallic smell from metal.
The blood of lobsters is colourless. However, when their blood is exposed to oxygen, it becomes a blue colour. This is mainly due to the copper that is found present in the blue hemocyanin molecule in their blood. Now that’s some cool scientific did you know the facts?
In Japan, napping at work is honourable. In Japan, napping at your job is seen as a sign of diligence—you are working so much, that you get exhausted. The Japanese call it inemuri, which translates to “present while sleeping.”
Rice is the oldest food we still eat today. In 2003, scientists recovered 15,000-year-old burnt rice grains in Korea. This makes rice the oldest known food that we eat till the present.
The real-life survivors attended the film’s premiere. As a testament to the film’s authenticity and impact, many Holocaust survivors were present for the highly anticipated premiere of “Schindler’s List.”
Africa is present in sections in all four hemispheres. The size of the African continent may come as a surprise to those whose education has been mostly centred on the West. For instance, it encompasses almost 12 million square miles and is spread throughout all four hemispheres. Yes, that’s how huge the African continent is.
One vending machine is present for every 40 people in Japan. With one vending machine for every 40 people, Japan is regarded to have one of the highest numbers of vending machines in the entire globe. The majority of them sell different kinds of beverages, although some also provide ice cream, noodles, and disposable cameras.
There are stars we will never be able to see. Ever since the Big Bang, most objects in space have been moving away from one another. The expansion of the Universe is accelerating. This is one of the facts about space that has rocked the cosmological boat over the past few years. As regions of space are whizzing away from one another at an ever-increasing rate, the first population of stars to form in the Universe are now too far away for us to ever hope of spying on them – even using the best present or future telescope. Hope is not lost; we can attempt to spot them indirectly via the energetic bursts of radiation they emit at the end of their lives.
Earth’s magnetic pole is creeping westward. Unlike our geographic North Pole, which is in a fixed location, Earth’s magnetic north wanders. Until the early 1990s, the magnetic North Pole was known to lie some 1600 km south of true north, in Canada. Yet scientists realised that the location of the magnetic north wasn’t fixed and was drifting at a rate of 15 km a year. Since the 1990s, however, the drift of Earth’s magnetic pole has turned into more of a sprint. Its present speed is around 50-60 km a year and is making a dash towards Siberia at a pace not seen before. Why? Scientists studying the drift of Earth’s magnetic north pole, using data from ESA’s Swarm mission, have pinpointed a change in the circulation pattern of magnetic blobs deep below Earth’s surface. They learned a change in the flow underneath Canada has caused a patch of magnetic field at the edge of Earth’s core, deep within the Earth, to be stretched out. This has weakened the Canadian patch and resulted in the pole shifting towards Siberia.
90% of the world’s data was generated between 2019 and the present.
Every person on Earth is living in the past. This may sound like the plot of some sci-fi, time-travel thriller, but it’s a fact of human biology and the trickiness of time. Our brains don’t perceive events until about 80 milliseconds after they’ve happened. This fine line between the present and the past is part of the reason why some physicists argue that there’s no such thing as “now” and that the present moment is no more than an illusion.
After an engineer named Sandford Fleming missed a train in 1876, he set out to change the way time worked. Fleming originally proposed a concept he called “Cosmic Time,” in which the world would run off an imaginary clock located at the planet’s centre, essentially a line from the centre of the planet to the sun. He then suggested splitting the world into 24 time zones labelled with a letter of the alphabet, with each zone spanning 15 degrees of longitude. His original plan to create a standard “Cosmic Time” was rejected, but it did lay the groundwork for a similar standardisation, so-called Universal Time. Nations present at the 1884 International Meridian Conference laid the groundwork for dividing the world into 24 time zones, with the Prime Meridian, also known as Longitude 0°, running through Greenwich, England.
Money Is Dirtier Than You Think: Both paper currency and coins can carry viruses and bacteria that can live on surfaces and easily transfer to your skin or onto other objects after touching them. Research has found physical currency changes hands at least 55 times a year or almost once a week. One recent study found banknotes made with cotton or linen fibres, such as U.S. dollar bills, present increased areas for germs and the capacity to retain moisture, which can make it an easier place for bacteria to thrive.
