This species of snail is called Clusterwink, they are often found in clusters of snails stuck on rocky shores on Australian beaches. This snail is considered the strangest snail in the world because they can emit light on their own. Unlike land snails that secrete luminescent mucus, Clusterwink snails are bioluminescent based on a chemical reaction inside their bodies. When any creature touches it, it emits a green flashing light Until now, the ability of the Clusterwink snail to glow is still a mystery to scientists. They hypothesized that this could be a tool to help them raise alarms, communicate with their fellow humans, or frighten enemies Fireflies or glow bugs are small beetles collectively known as the family Fireflies that are luminescent. Fireflies are typical of temperate regions, although most species live in tropical and subtropical regions Fireflies are divided into two groups: flying fireflies and fireflies crawling on the ground. Both of these groups can emit the same special cold light, which does not radiate heat like artificial light The light of fireflies is emitted from the last few segments of the abdomen. During the day, these nodes are only gray-white in color, at night they emit subtle light through the transparent skin, with reflective cells that have the function of reflecting light out. Plankton occurs in most of the world’s beaches, especially in the Maldives. They emit a blue light, and tend to glow more strongly in the presence of waves This luminescent light acts as a signal to scare away enemies with color, an implicit warning to the enemy. On the other hand, it also distracts the enemy, distracting the enemy, the plankton uses that opportunity to escape. In addition, according to scientists, bioluminescent plankton is a signal to attract and support larger organisms to hunt copepods – enemies of plankton. Atolla jellyfish live in the depths of the ocean. They have 22 tentacles, one of which is larger than the others and is used to catch prey, this jellyfish is known as the “moving lamp” of the sea. Unlike many other jellyfish, the Atolla jellyfish when attacked will immediately glow brightly. The light it emits can illuminate as far as 91.44m At that time, larger species will be attracted to this light and rush to it. Then the hunter becomes the prey again and the jellyfish will take this opportunity to escape Atolla jellyfish often use tentacles to catch prey. When the prey has been captured by the tentacles, they swing back and forth until the prey has no resistance and then enjoy. The anglerfish, also known as anglerfish – literally “fishing rod fish”, this fish has a fleshy nodule that grows from the head to become a luminous organ that functions as a bait During hunting, this part of the fin will glow, making the fish around it attracted. After that, their job is just to open their large mouth and take the whole prey into their stomach It is known that Anglerfish are considered the “demon” of the ocean floor because they have extremely ugly but extremely sharp teeth, this fish often lives in the deep sea, without light. In the forests of some Asian countries, including Vietnam, people still often encounter glowing mushrooms. This mushroom has the scientific name Omphalotus nidiformis but is often referred to as the “ghost mushroom”. Ghost mushroom is considered a poisonous mushroom that contains illudin compound – a luminescent substance or phosphorous substance that causes poisoning to humans when ingested. Mushroom poisonings often occur in the winter and spring, when fungi grow and develop. Therefore, people absolutely should not go to the forest to pick wild mushrooms to eat Geckos are a famous creature, known to many people because they have the ability to change color continuously according to the season and weather. However, very few people know that, under ultraviolet light, the bones of many chameleon species are also capable of emitting fluorescent light. This strange millipede is a millipede, scientifically known as Motyxia sequoia. Scientists think this millipede evolved a way to glow in the dark to cope with the stress of life when living in a hot, dry environment. In addition to stress relief, the blue light emitted by the Motyxia sequoiae mat also warns predators that they may spew out cyanide. When the light this millipede emits is not enough to ward off danger, they also ooze toxic cyanide and foul odors from their small feet. This millipede is blind, so they cannot attract each other with light, nor do they use light to attract prey. The ability to glow is just an odd defense mechanism of this creature

Primates make laughter when they play. However, laughter in animals often means an invitation to mate, join a herd, or find food. The meaning of animal laughter Laughing together helps people connect and bond. Although the reason for laughing can vary widely between individuals and groups, this sound can still be distinguished from crying, screaming, groaning or shouting. In humans, laughter expresses a wide range of emotions, from positive such as amusement to negative such as annoyance. People laugh when they hear an interesting story or when they see funny things. But what about animals? Do they laugh and is the reason they laugh the same way humans laugh? It’s hard to tell if animals have a sense of humor like humans. A study published in the journal Bioacoustics in April 2021 found that when communicating, animals sometimes make sounds that have a comforting, pleasant nuance. Sasha Winkler, lead author of the study, at the University of California, Los Angeles (USA), said that rhesus monkeys (scientific name Macaca mulatta) often pant when playing. This is the inspiration for her and her colleagues to expand their research on animal laughter. They looked to see if other animals let out gasps like rhesus monkeys during play. The researchers say that such sounds closely resemble human laughter. They continued to study the prevalence of laughter among animals. The team identified 65 species that “laughed” while playing, most of which were mammals. Some birds also make cheerful sounds. This analysis helps scientists go back to the evolutionary origins of laughter in humans. When playing, animals may cry or laugh to keep interactions at a harmonious level, not becoming aggressive. Unlike fighting, the concept of play in animals is often mating, foraging. Play can be clearly seen in primates because their facial muscles show human-like expressions when playing. The study grew out of an experiment from 2017 on kea parrots living in New Zealand. Experts recorded the laughter of the kea parrots and played them back for others to hear. As a result, these parrots will play together relatively closely. This study shows that the laughter of kea parrots is like an invitation to others to join the flock or to feed together. Investigation results show that mammals, especially primates, rodents, carnivores and cetaceans emit similar sounds. These sounds are only emitted when playing, such as the whistle like the whistle of a bottlenose dolphin (scientific name is Tursiops truncatus), the hiss of a mouse. Most primates, including chimpanzees, gorillas, monkeys, and baboons, exhibit laughter by: panting, smirking, chuckling to “click, clack” and loud cries. . Birds emit laughter to attract their fellow humans. Laughing is not just for fun Research also shows that fish, amphibians and reptiles do not produce laughter because this group may not organize play activities. However, laughter between humans and animals is quite different. Usually, people’s laughter shows that they are having fun or sharing their joy with those around them. People also put laughter into communication to express their attitudes and feelings towards the behavior of people around them. For example, smirking, sarcastic laughter, sarcastic laughter to express a reaction of praise or disapproval of the actions of people around. But in some animals, laughing is not synonymous with cheerfulness. For example, hyenas often laugh when feeling dangerous, threatened, attacked or simply upset. Human and animal laughter also differ in volume. For example, older hyenas often laugh at a low pitch while young hyenas’ laughter is high, even shrill. Some species laugh very softly, just enough for the other person to hear. While human laughter is loud, loud and nuanced. Before Winkler, in 2000, Jaak Panskeep, a psychologist and neuroscientist working at Washington State University, USA, discovered that tickled rats emit chirping sounds similar to the sounds they make when they play. Some lab rats liked to be tickled so much that they simulated this amusing activity. From there, Panskeep and his colleagues began to seriously study the play of animals. He identified seven basic emotional expressions activated by the mammalian brain. Since then, he has applied this result to the study of human emotions and found a treatment for depression in humans. Panskeep has clinically developed an antidepressant, named GLYX-13. He considers this modulation product to be proof that scientists should seriously evaluate the emotional state of animals. Animal studies could pave the way for the development of psychopharmaceuticals for humans. He also added that we think rats and monkeys can laugh because they are smart. But in fact, intelligence is not a funny factor. Play in any animal can stimulate laughter, increase cognitive ability.

Nghinh Phong Tower is located in the Square architecture of the same name in Phu Yen. The tower is inspired by Ganh Da Dia, round blocks of stone stacked side by side, combined with the traditional Vietnamese culture of “the legend of a hundred eggs” Lac Long Quan and Au Co. (Photo: Facebook) These blocks are the images representing the 100 children in the legend, divided in half with the meaning “to the forest – to the sea”. In the middle will be two tall towers, the higher one representing Lac Long Quan and the other, lower tower representing Au Co. The space between the towers is only enough for two people to stand, and every time the wind blows through the gap, it will create a sound, like music. Each wind blowing is a different music, visitors will only hear that sound once in a lifetime. (Photo: Ngoc Thong) The middle aisle is highlighted by decorated with reliefs depicting the history and culture of Phu Yen. The ground is fitted with a lighting system incorporating 3D technology. When it gets dark, the whole area will be lit up, creating a lighting effect that attracts the attention of visitors, especially at the location of the slit. Visitors coming here in the evening will be treated to a laser light and sound show. In front of the ocean is the wind blowing, the sound of waves lapping, cool at night. (Photo: Phan Nguyen Khiem) The stone blocks of the tower become the ideal “virtual living” background for young people. At sunset, this place is very crowded with people taking pictures and walking around, so it is difficult to take a good photo. If you want to be away from people, take advantage of going early to watch the sunrise while enjoying the fresh and pleasant morning air. (Photo: Thanh Nhan) (Photo: Thanh Nhan) As soon as it was launched, the tower was quickly visited by many young people to visit and check-in. With a unique and modern architecture located opposite the cool and windy beach, it is not difficult for young men and women to take “genuine” photos as if they were checking-in abroad. Let’s admire more “quality like distilled water” frames of Nghinh Phong tower through the camera lens!

Mysterious sounds often occur from crescent-shaped sand dunes. They say they often emit mysterious sounds, ranging from soft hissing, melodious kite flutes, to roars, or terrifying explosions, that can be heard from miles away. As real as
how? Strange sound from sand dunes The first mysterious stories of strange phenomena in the desert are said to have come from the legendary explorer Marco Polo in the 12th century. He described these anomalous sounds as “sounds emanating from various types of music. instruments, drums, and the clash of arms”, and claimed that they were the “works” of evil spirits lurking in the desert. Up to the 19th century, these monstrous sounds still toyed with adventurers in the wilderness, even mentioned by Charles Darwin in his travel diary, but he could not explain this strange phenomenon. A remarkable documentary on strange sounds was produced by the British diplomat and explorer, Bertram Sidney Thomas. In 1930-1931, he became the first Westerner to cross the Rub ‘al Khali, or “Empty Quarter”, a vast expanse of desolate expanse of the Arabian desert. During this expedition, he noted the “loud sound of a musical note” emanating from a gentle sand slope. On another occasion, he even heard musical notes emanating from under his camel’s feet. The adventurer was also awakened by high-pitched sounds while sleeping in the tent. When he asked his local guide about the origin of these sounds, he was told that they came from spirits conversing with each other in another world. An explorer named John Philby who was also in the “Empty Quarter” at the same time as Thomas said of what he heard: “Suddenly in the large area began to emit sounds like a siren. or the sound of an aircraft engine, it sounds quite fun, rhythmic and has amazing depth. This “sand concert” lasted about four minutes, which was enough for me to record every detail after I recovered. Such strange sounds, commonly known as “singing sands” or “songs of the dunes”, have been reported for centuries, from places as far away as North and South America, Africa, and Europe. Asia, British Isles, Arabian Peninsula, Hawaiian Islands. The cultures in these regions all have their own legends and myths surrounding this phenomenon. For the Arabs, they were created by desert spirits called Jinn. Many other places for these strange sounds come from lost cities underground, or from ghosts, gods, demons, mythical animals, even demons. The cause has not been determined Explorers sometimes heard musical notes emanating from beneath the camel’s feet. Explorer Philby was one of the first to explain this phenomenon scientifically. He realized that the sounds he heard seemed to coincide with a rain of sand falling from where one of his guides was sitting. He then heard the sand make various noises, such as barks, groans, booming music, or the sound of a trombone or organ, when they were disturbed with different objects. . He thinks that sand itself has certain properties that help them make these sounds when subjected to friction. However, he was not sure about the exact mechanism of this phenomenon. The phenomenon of “singing sand” has many different forms. In the dunes, they often emit sounds such as rumbling, groaning, humming or explosion, thunder, low-flying planes, which can last 15 minutes and reach up to 105 decibels, often heard at a distance. The mysterious sound occurs almost exclusively from crescent-shaped sand dunes, known as barchan, accompanied by wind blowing, or someone walking along a mountain top. “Singing sand” can also be heard at some beaches in the form of hissing, singing, whistling or screaming. In both the dunes and on the beaches, the variety of sounds is very different, the frequency range in which they are emitted is also different. So far, no one has determined what causes these strange sounds, nor why they emit so many different forms with different intensities. It has been suggested that it is due to the friction between the large number of sand grains. The size, texture and uniformity of the particles determine the sound pattern and volume produced. One theory is that it is the result of sound waves bouncing back and forth between the surface of the dune and the surface of the wet layer. According to some scientists, the sound comes from the compression of air between sand grains, or from sand sliding, the movement of one layer of sand relative to another. However, there is no convincing hypothesis. It is worth noting that this phenomenon is quite rare in nature, with only 35 known locations of singing sands around the world. The “Song of the Sand Dunes” has been part of the myths and legends of many different cultures for thousands of years, but so far, despite great advances in science, natural phenomena This is still a mystery waiting to be solved.

Russian submarine of the Lada class. (Source: Sputnik) According to the author, the Lada submarine’s hull is teardrop-shaped, aerodynamically, this helps to avoid turbulence and makes almost no noise. Hydrogen-oxygen fuel cells that generate electricity for the propellers also play an important role in enhancing the submarine’s noise-cancelling properties. Although there is a diesel generator, but like other diesel electric submarines, in the Lada class, electricity is also generated through a chemical reaction, which helps to reduce engine noise. Currently, Russia is building two types of diesel-electric submarines, class 636.3 (Varshavyanka) and class 677 (Lada). The Varshavyanka class was created on the basis of the 877 Paltus class of the former Soviet Union. The Black Sea Fleet has already received six of these ships, and by 2024, a batch of six submarines will be delivered to the Pacific Fleet. Earlier, General Director of Admiralteyskie Verf shipyard Alexander Buzakov said that the first two mass-produced diesel electric submarines of the fourth generation of the 677 Lada class will be equipped with Kalibr cruise missiles. The Kronstadt and Velikie Luki submarines, the second and third of the project 677, are scheduled to be delivered to the Russian Navy next year. The Saint Petersburg submarine – armed only with mines and mines, joined the Russian fleet in 2010. (according to The National Interest)

However, one sense that humans can soon master, is bat-like echolocation. Sixth sense experiment According to the Popular Mechanics Scientists in Japan have tested this ability in a laboratory, proving that humans can use it echolocation , or the ability to sense echoes for navigation. This ability helps people recognize the shape and rotation of many objects. Thanks to that, people can “see” in the dark. When the volunteer presses the tablet, a synthesized echo is emitted from the amplifier speaker (red line). The sounds obtained with the binaural are 1/8 of the original pitch by reducing the sampling frequency, which is transmitted into the volunteer headphones (green line). Photo: Miwa Sumiya. As bats fly around objects, they emit intense sound waves from different angles and bounce off at isolated intervals. Thanks to that, this tiny mammal can determine the topography, texture or movement of an object. According to Dr. Miwa Sumiya, if humans were able to perceive the patterns of time-changing sounds similar to bats, they could see the world in new ways. Dr. Sumiya, a researcher at the Center for Nerve and Information Networks in Osaka, Japan and was the first author of a paper to appear on Plos One on this topic. “Testing that humans are capable of detecting multiple environments via sound waves could add a new step in understanding the complexity of the human brain,” Sumiya said. According to Sumiya, humans have the ability to further understand the perception of other species (such as bats) by comparing with knowledge gained in echolocation studies of humankind. To test this theory, Mrs. Sumiya’s group made a meticulous arrangement. In one room, the researchers gave volunteers a pair of headphones and two tablets, one that produced a calibrated signal using a synthesized echo, the other to listen to pre-recorded echoes. . In room 2, only the strangely shaped 3D axes stand in one place and rotate around themselves. When prompted, 15 volunteers turned on echolocation signals from their tablets. The sound waves emit each beat, travel to room 2 and hit the 3D axes. Participants need a little bit of imagination to convert sound waves into a certain object. Sumiya explained that the synthesized echo-locating signals used in this experiment were high-frequency signals up to 41 kHz, which cannot be heard by humans. Dolphins are also a mammal that uses echolocation to detect and hunt. Photo: Getty Images. Researchers used a humanoid (1/7 the size of a real skull) to “hear” the sound in room 2 before passing it on to volunteers. The fake head is equipped with 2 microphones attached to the two ears and creating a 3D resonance. The sound output is quite similar to the surround sound experienced in movie theaters. Reducing the frequency of the echoes in both ears enabled volunteers to hear “with the feeling of being heard in real space”. Many people like to listen to podcasts or watch videos with headphones to create surround sound and give a tingling sensation in their ears. This is called the Autonomous Sensory Meridian Response, or ASMR. Result Finally, researchers and volunteers guessed whether echoes were coming from stationary or spinning objects. At the end of the experiment, the volunteers were able to accurately identify two pillars thanks to the time-varying echolocation signals emanating from them. Identifying clue is thanks to the pitch and timbre. However, it was difficult for them to discern the shape of the standing pillars. Sumiya’s group study is not the first to test the ability of human echolocation. Previous studies have shown that blind people can use mouth-clicking sounds to see 2D objects. However, Ms. Sumiya said her experiment was the first to specifically explore the ability of echolocation to change over time. The researchers said their work is evidence that both humans and bats are capable of decoding objects through sound. In the future, engineers could apply this technology to wearable devices such as watches or glasses to improve how visually impaired people can navigate the world, except for headsets.

I’m a pretty neat person. Furniture when going home like backpack, glasses, keys or wallet are stored in the correct tray in a box next to the door. Thanks to that, I rarely have to look for things that are important to me before going to work. However, no matter how neat I am, there are times when I lose my belongings. I dropped the wallet on an acquaintance’s car, and because the wallet fell into the slot under the seat, my friend couldn’t find it. Had it not been found by the car washer, I might have had to go over and over again. These are situations where a misplaced device like the AirTag comes in very handy. I was very excited when Apple introduced the AirTag, but it still has many inconveniences when it comes to real-world experience. Accessories “cheap” in the Apple way Excluding EarPods or chargers, AirTags is Apple’s cheapest standalone product. This accessory has a genuine price of about 800,000 VND, and if you buy a set of 4, the price is a bit lower. However, for many this will not be the final price to be able to use AirTag. The device has a round design and two sides are not flat, meaning it is difficult to secure in the compartment of a handbag. Leaving AirTag in your wallet just makes your wallet look good, while lowering your device’s notification volume. AirTag is also quite thick, so placing it inside thin wallets will make the wallet look up quite a lot. In addition, if the AirTag is placed in the wallet or compartment too thin, the efficiency will also decrease. The solution now is to buy a leather pouch. Although there are no prices in Vietnam, the genuine bags that Apple sells are priced equal to or several times higher than the AirTag itself (from 29-449 USD). Leather cases of craft units in Vietnam also cost about 200,000 VND or more. If you buy this accessory, the price of AirTag will be nearly 1 million dong. AirTag pairs very quickly with iPhone. Due to not being able to buy a holster in time, I used the “bare” AirTag, and immediately understood why a holster was needed. In less than a day of use, leaving this accessory in the backpack and wallet compartment, both the aluminum and plastic sides of AirTag have had scratches. Actually scratches will not affect the function of the device, but for those who require high looks, these are still the points to pay attention to. Well done the main function Connecting AirTag to iPhone is very simple. Just bring the accessory close, the machine will automatically recognize and the set-up takes only about 30 seconds. This is a big plus compared to other finder devices. To find items attached to AirTag, users have 3 ways. First, they can go to the Find My app, choose to show up on the map to see the last recorded location. If you are in the same apartment, you can press the speaker button to let the AirTag play the sound. The third method only applies to iPhone 11 onwards, allowing the display of the direction and distance to the nearby AirTag. The “exact find” function worked quite well, but still occasionally lost the signal. The Find My network with billions of devices running iOS is a huge advantage of AirTag. No need GPS or network connection, users can still find the AirTag when it is near any iOS device. Testing in city conditions, I found the position of AirTag on the map was quite accurate. The challenge will come when you want to find the AirTag nearby. The AirTag’s “speaker” is in fact the white plastic side of this device. When you select a sound feature, the plastic face vibrates to create sound. This sound is only enough to be heard in an apartment, when the background noise is quite small. If you search inside a multi-storey house, or assume your family member has the TV turned on quite loudly, you will be hard pressed to hear AirTag’s sound. This is why you should not leave AirTag inside your wallet too tight. At that time, the volume of AirTag emitted will be much smaller, reducing the efficiency when searching. The search when the AirTag is lost is quite effective, the address is accurate. The UWB wave precision search is also useful, but efficiency depends on the environment. When I tried to leave AirTag in the living room of a 2 bedroom apartment, the iPhone frequently reported “weak signal” when I went into one of the bedrooms. Only when the distance is less than 4 m, and there is no barrier between the iPhone and the AirTag, can the device be able to accurately indicate the distance and direction. Combining all 3 of these features, the ability to find lost items will increase significantly when attached to AirTag. However, there are still environments where AirTag is not very efficient, like in a large apartment, or in the middle of a crowded shopping mall. It is also not suitable if you want to leave it on your motorbike to look in the parking lot, as cheaper and louder accessories are available on the market. It would be disastrous if used the wrong way At launch, Apple stated that the AirTag was an accessory “to track things, not to track people”. The company also integrates a number of features so that users know when someone else’s AirTag comes with them. However, in practice these features all have vulnerabilities. The current AirTag can still be used to spy on others. The first way AirTag notices is sound. According to Apple, after “a while”, if an AirTag is separated from its host device, it will squeal to get attention. The company did not specify how long that period was. Just squeeze or stick the tape around the AirTag and the sound will be very soft. According to the Washington Post , it took three days since the last time away from the owner, the AirTag cried for about 15 seconds, and then rang every few hours. The 3-day period is quite a long time for AirTag owners to keep track of the places the victims visit. Besides, reducing the sound of an AirTag is not difficult. If you detect an AirTag that is not with the same account but has been nearby for a long time, the user’s iOS device will also pop up a message saying there is a strange AirTag. The victim can press play to find the strange AirTag, but cannot access the map or find the exact same as the official AirTag. However, in my hands-on experience carrying the strange AirTag all day, I never get a notification on my iPhone. Also, if the victim uses an Android phone, they won’t receive any notifications. AirTag uses the familiar CR2032 battery, sold in every watch shop. AirTag still has many vulnerabilities to be misused. That’s not to mention if the AirTag owner is spying on a relative and knows their iPhone’s password, that person can go into the Find My app and turn off notification when it detects a strange AirTag. Although Apple promises very well, AirTag can still be used as a tracking device for others. In the future, the company may update to reduce the alarm interval or adjust the notification feature. At present, AirTag still has many major vulnerabilities that can be exploited for the wrong purpose. Should I buy AirTag? If you are an iPhone user and forgetful, AirTag will be a very useful accessory, especially with important objects. The price of nearly 1 million is not high compared to the effort of redoing papers in your wallet, or hitting a car key. AirTag can be said to be a huge reason iPhone users continue to stick with Apple’s ecosystem. However, if you do not use an iPhone, there are many other options on the market, with prices as low as half the Samsung SmartTag or Baseus Intelligent T3.

An upcoming luxury apartment building in Brooklyn (New York, USA) is driving residents here crazy because it emits noises like whistling but very shrill, disturbing the area quite quiet. this static. Many people compared that bizarre sound to the sound of iron nails scratching wooden boards, which several buildings also heard. This expensive apartment building let out shrill shrieks. Photo: ABC. “It is like a whistle but very high, into a very scary hiss” – said a resident. Some others said, as if there was a dinosaur standing on top of a building howling. Therefore, people call this apartment building the “shouting building”. Residents said this horrible sound has only been released for about 3 months now, when it was loud and small, maybe due to the wind speed, but it was especially annoying for some sensitive people or those who were learning and work from home and need to focus. Therefore, the residents here asked the building and development company to find out what was going on. Many people in the area have lost sleep because of the strange sounds coming from the building. Photo: Lendi. The company said they would monitor the issue, but the people around here were impatient because the hissing from the building lasted for months kept them in a stressful mood, some people were worried and lost sleep. Some engineers said that this is not a mystery, but it may be due to the balcony. Accordingly, the wind blowing through the vertical bars in the balcony caused a hissing sound. Some engineers believe that the vertical bars in the balcony are to blame. Photo: ABC. But whatever the reason, the people here just hope the company has a solution quickly, but no one can live every day in such horror sounds. Thuc Han According to many sources

She wears a close-fitting skirt with navy blue tones with V-shaped cutout on the neck and is accented with a large pearl necklace. However, the latex fabric makes the wearer inconvenient, and when moving, it will create less charming sounds like the sound of fart.

Katy Perry wore Bottega Veneta’s dress.

“If you think I’m deflating on TV, it’s really not. I feel a bit shy about the sound coming from the dress,” Katy Perry shared.

The audience also left comments below the vocal post Roar. Many people understand the female singer’s feelings and think that this is a common sound that the wearer. The rest identified that latex fabric is somewhat outdated in 2021.

Account @leoairton said: “Katy Perry always creates humor with every outfit she wears American Idol. The dress is very sexy but I think Katy also has a lot of trouble wearing it.

On March 15, Daily Mail reported on an episode of the show American IdolKaty Perry surprises the studio with his act of revealing underwear designed specifically for people who have just given birth to babies.

During this recording session, Katy Perry’s daughter was accompanied by her mother to the backstage area. During a break, judge Lionel Richie introduced to the audience that: “Katy’s daughter is in the room. Katy, please show it.”

Immediately after the offer, the female singer stood up and said: “Yes. If she asks for food, I will go right away.”

Then, she stripped the front part to reveal the inner underwear specially designed for mothers with young children.

This act of the female singer surprised the audience and created a controversy about the lack of charm on television.

Now, the wild mountain gorilla (Gorilla beringei beringei) in Rwanda’s Volcanoes National Park has “confessed” to the scientists secretly beating their breasts.

The research has been published in the journal Scientific Reports under Nature and led by Dr. Edward Wright of the Max Planck Institute of Evolutionary Anthropology in Germany.

The mountain gorilla (Gorilla beringei beringei) is one of two eastern gorilla subspecies, comprising two populations. A population found in the Virunga volcano in Central Africa belongs to three national parks: Mgahinga, in southwestern Uganda; Volcanoes, in northwestern Rwanda; and Virunga in the eastern Democratic Republic of the Congo. The remainder was found in Bwindi Prohibited National Park in Uganda. Some primateists consider the Bwindi population a separate subspecies, although no complete description has been made. As of November 2012, an estimated total population of mountain gorillas was 880 individuals.

From January 2014 to July 2016, researchers observed 25 wild male silver-backed gorillas overseen by the Dian Fossey Gorilla Fund International (Dian Fossey Gorilla Fund International), and recorded more. 500 chest beats.

They recorded the chest beating sounds of six of the gorillas, measured the rhythm and duration of each gorilla’s chest beat, and the frequency of the chest beating sounds. At the same time, they used the photographs to measure the shoulder widths of these gorillas to determine the sizes of different gorillas.

Mountain gorillas are descendants of monkeys and ancient apes found in Africa and Arab in the early Oligocene (34-24 million years ago). The fossil where the mountain gorilla lives is poor and its evolutionary history is unclear. About 9 million years ago, a group of primates evolved into gorillas, separated from their common ancestors with humans and chimpanzees; This is when genus Gorilla comes in. The mountain gorilla split from the eastern delta gorilla about 400,000 years ago and the two subspecies split from the eastern gorilla about 2 million years ago. There is much unresolved debate about the classification of mountain gorillas. The genus Gorilla was originally named Troglodytes in 1847, then renamed as it is today in 1852. By 1967 taxonomist Colin Groves proposed that all Gorilla genus consisted of only one species (Gorilla gorilla) with three Subspecies Gorilla gorilla gorilla (western plains gorilla), Gorilla gorilla graueri (delta gorilla found in western Virungas) and Gorilla gorilla beringei (mountain gorilla). In 2003, after review, gorillas were divided into two species (Gorilla gorilla and Gorilla beringei) by the International Union for Conservation of Nature (IUCN).

After analyzing these measurement data, they found that “mountain gorillas can reliably transmit body shape information by beating their chest”. Specifically, large males will emit a lower frequency sound when they strike the chest. Researchers speculate that this may be related to their body’s large resonance cavity.

Researchers also found that males pound their breasts more often during oestrus in female gorillas, so the sound of the chest beats can be an important physical manifestation during flirting, a on the one hand, attracting children, and on the other hand, frightening the opponents.

Interestingly, the beats and timing of these gorillas have nothing to do with body size, and not that the larger the size, the longer the beat. The chest beat of each gorilla is like a behavior showing the different personality, duration and frequency that will carry the characteristics of each individual. Researchers have analyzed that personalized beats could allow other gorillas to distinguish who was beating their chest from them.

Mountain gorillas have been reported to have led to a threat of extinction due to poaching – mountain gorillas are often permanently injured by traps. hunt wild animals or take young individuals to zoos.
