  Bullfighting is one of the most popular and controversial customs in Spain. Every year in the summer, people flock by the thousands to see a bullfighter (matador) wave his red cape (muleta) in front of a snorting bull. The bull sees the flaming, arrogant red color and charge angrily towards it.  Bulls don’t get agitated by the color red. In fact, there is very little evidence for any color aggravating bulls into causing damage. Bulls, like other ungulates (animals with hooves), have dichromatic vision. But this dichromatic vision doesn’t say much about how bulls distinguish color. Many experiments have been carried out looking at how bulls perceive and distinguish color. These experiments have noted that bulls can differentiate between different colors but none of them have conclusively associated the color red with aggression. It’s not the color, but rather the movement of the cape and the bullfighter that makes bulls so angry. Moreover, the bulls used in bullfights are from a very

  The earliest diamonds were found in India in the 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along with the network of trade routes that connected India and China, commonly known as the Silk Road. At the time of their discovery, diamonds were valued because of their strength and brilliance and for their ability to refract light and engrave metal. Diamonds were worn as adornments, used as cutting tools, served as a talisman to ward off evil, and were believed to protect in battle. In the Dark Ages, diamonds were also used as medical aid and were thought to cure illness and heal wounds when ingested. Surprisingly, diamonds share some common characteristics with coal. Both are composed of the most common substance on earth: carbon. What makes diamonds different from coal is the way the carbon atoms are arranged and how the carbon is formed. Diamonds are created when carbon is subjected to th

  From September 1960 until October 1962, Rogozov worked in Antarctica, in his role as the sole doctor for a team of thirteen researchers at the Novolazarevskaya Station, established in January 1961. On the morning of 29 April 1961, Rogozov experienced general weakness, nausea, and moderate fever, and later pain in the lower right portion of his abdomen. None of the possible conservative treatments helped. By 30 April signs of localized peritonitis became apparent, and his condition worsened considerably by the evening. Mirny, the nearest Soviet research station, was more than 1,600 km (1,000 mi) from Novolazarevskaya. Antarctic research stations of other countries did not have aircraft available. Severe blizzard conditions prevented aircraft from landing in any case. Rogozov had no option but to perform an operation on himself. The operation started at 02:00 local time on 1 May with the help of a driver and meteorologist, who provided instruments and held a mirror so Rogozov could obs

 A man named Waqas Shah conducted a social experiment in which he dropped a wallet containing 2000 dollars. A man saw Shah's wallet fall and picked it up and returned it. When questioned, the man named Jay confessed that he was a homeless person and because of his honesty in returning his wallet, Shah gave him some money. Unexpectedly, Shah, who was st ill recording it, secretly watched Jay immediately buy food. But to his surprise, Jay didn't just buy it for himself but he bought it for his fellow homeless friends. Even though he is lacking, Jay does not hesitate to share what he gets with others who are equally in need.  https://www.dailymail.co.uk/news/article-5775215/Homeless-man-spends-money-getting-food-homeless-people.html.

 NASA's exoplanets Twitter account unveiled audio where listeners can hear what a black hole from 200 million light-years away sounds like to the human ear. The space agency also used the tweet to address the widely misunderstood notion that there is no sound among the stars. "The misconception that there is no sound in space originates because most space is an acuum, providing no way for sound waves to travel," they wrote. "A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole!" they excitedly tweeted alongside a video clip of said

  While adult giraffes usually sleep standing up, baby giraffes will get a bit more comfortable. They hunker down on the ground and take advantage of their extra-flexible necks, twisting around to plop their noggins on their own behinds. It doesn't look especially comfortable, but it sure does look cute!

  The blobfish hovers above the seabed, meaning they live in some of the deepest parts of the ocean. Due to the pressure down there, the gelatinous body mass of the fish is given structure. The high pressure at such depths allows them to look like regular fish. However, when they are brought to the surface, and the pressure drops, they appear droopy. Their body mass isn’t supported, and they appear like a blob. This is because they have no skeleton and very little muscle. The pressure at the seabed is around 120 times higher than on land, meaning they are held into shape.
