  His name is Mahathir Mohamad. He has sworn in as the Prime Minister of Malaysia at the age of 92. Thus, making him the oldest Prime Minister of a country.  Wearing a headphone for just an hour will increase the bacteria in you ear by 700 times. This is the 12th century's Airateshwara Temple in Tamil Nadu, India. The temple is dedicated to lord Shiva. The speciality of this temple is the musical steps made of stones. The step produces 7 different musical tones also called sapta swara when tapped at different points. The temple was built by Rajaraja Chola, also this temple is a UNESCO World Heritage Site.  The trees at southernmost part of New Zealand grow sideways because they are constantly swept by the Antarctic winds. Scientist Pascal Cotte analysed 1,650 high - tech camera images over the course of 15 years to uncover the hidden sketch behind Mona Lisa painting. He used infrared technology to detect the tiniest details hidden beneath the painting.

 Did you know about these mysterious statues of Unakoti? According to local legends, this place has over 1 crore sculpture but nobody can find them, as they are hidden in the lush green forests. Why would have anyone made over a crore sculptures in this place. The name Unakoti means one less than 1 crore(koti means 1 crore). There is a story which says that there was a man names Kallu, who wanted to accompany Lord Shiva and  Goddess Parvati to Mt. Kailash but Shiva wasn't too keen on taking him along and gave him a task of making 10million sculptures before dawn. He was short of only one and thus, the place got it's name.  In the 1960 Earthquake, may of these sculptures were broken and also stolen as India & Bangladesh borders weren't sealed. New waterfalls emerged and washed away lots of other carvings. This is why we can't find a crore statues in the present day. Unakoti is not a mobile place and tourism in not well developed. 

 In the difficult times of crisis when America turned off its head, Russia extended it's helping hand to India.  In the difficult times when there are shortage of oxygens in many parts of India and shortages of beds. Also a matter of concern : there is not much oxygen left, Delhi has reduced certain number of beds as the Doctors had said that there is no such oxygen supply to cure the patient's problems. This step was taken due to the death of 25 Covid patients in the Jaipur Golden Hospital , Delhi.  During this oxygen crisis, Russia has come front to help India in supplying oxygen. Some sources also proclaim that India is planning to buy  some oxygen concentrates and tanks from   Russia. If this idea gets the positive results then the    oxygen crisis would help India a lot during this time.

  In a new research , mathematicians have revealed new category of prime numbers " digitially delicate ". This infinitely long prime numbers turn back to composites faster than cindrella at midnight with a change of any individual digit.  These digitally delicate prime numbers have inumerous digits , and changing any digit to any other value bears a composite number outcome instead. To use a more simple example, consider 101 which is a prime number. Change the digits to 201 , 102 or 111 and you will have values that are divisible by three and therefore compound numbers.  But this idea was found to be decades old , so what did the mathematicians found new ? The mathematicians from the University of South Carolina have established an even more specific niche of the digitally delicate primes: widely digitally delicate primes. These primes are added with infinite " leading zeros ", which don't change the original prime, but make a difference as the number of zeros a

  It is interesting to know that both the world's largest and smallest river islands are situated in the Brahmaputra river in Assam. The smallest one is called UMANANDA (Also called Peacock Island) and the largest is known as MAJULI .   These islands attract visitors from every corner of the globe. Some people say that Lord Shiva created the Peacock island for his wife Parvati’s happiness. The island was also very popular for it's golden langurs, which is one of the most endangered primate species of India (The last one surviving is now reportedly dead). The main attraction of the Umananda island is the Umananda Temple which was built in 1694CE  in the order of King Gadadhar Singha but was broken down by an earthquake in 1867.  Majuli is a river island in the Brahmaputra River, Assam and in 2016 it became the first island to be made a district in India. It is now being eroded at a very great speed.

  Sierra Nevada: This forest in California provides a diverse range of habitats , having about 400 species of endemic and 200 species of rare vuscular plants. Unfortunately, it is threatened by grazing, fire, urbanisation, logging and mining forests.  Sundarbans: The forest is the part of world's largest delta which is formed by the river Ganga and Brahmaputra. The name is said to be delivered from the word sundari, a reference to the large kind of sundari trees which exist there. It is also a site of tiger preservation project. Tropical Rainforests: These forests are located generally in hot, wet and equator regions. These forests are filled up with evergreen trees. It is also estimated that half of the world's plant and animal species live in these forests.  Coniferous Forest: These forests are found in areas where there are moderate to heavy annual rainfall and long winters. They are similar in shapes and height and often form a nearly uniform stand with a layer of low shru

Tikal was an important capital city of the Mayan Kingdom. The site was occupied for more than 700 years.  Tikal National Park is located in Northern Guatemala's Petén Province within a large forest region often referred to as the Maya Forest, which extends into neighbouring Mexico and Belize. The Tikal Ruins, which was established in the years of 1950s, is the central attraction of the Tikal National Park. The site was abandoned by the 10th century after years of occupation.
