MARIANA TRENCH

Image
            T he Mariana Trench or Mariana Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent - shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.           At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).              In 2009, the Marianas Trench was established as a US National Monument.Monothalamea have been found in the trench by Scripps Institution of Oceanography researchers at a record depth of 10.6 kilometres (6.6 mi) below the sea surface. Data has also suggested that microbial life forms thrive within the trench.  HISTORY :-          The trench was first sounded during the Challenger expedition in

HAVANA SYNDROME

            H avana syndrome is a mysterious illness  and was first reported by United States and Canadian embassy staff in Cuba dating back to late 2016 as well as subsequently in some other countries, including the United States.               In 2017, Donald Trump accused Cuba of perpetrating unspecified attacks causing these symptoms. The U.S. reduced staff at their embassy to a minimum in response.[8] In 2018, U.S. diplomats in China reported problems similar to those reported in Cuba, as did undercover CIA agents working in other countries with partner agencies to counter Russian covert operations.               In August 2017, reports began surfacing that American and Canadian[17] diplomatic personnel in Cuba had experienced unusual, unexplained health problems dating back to late 2016.[18][19] The number of American citizens experiencing symptoms was 26 as of June 2018. SYMPTOMS:-               A report published by the National Academies of Sciences (NAS) last year breaks it a

ZIKA

 Zika virus is a mosquito-borne flavivirus that was first identified in Uganda in 1947 in monkeys. It was later identified in humans in 1952 in Uganda and the United Republic of Tanzania.           Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Asia and the Pacific. From the 1960s to 1980s, rare sporadic cases of human infections were found across Africa and Asia, typically accompanied by mild illness.           The first recorded outbreak of Zika virus disease was reported from the Island of Yap (Federated States of Micronesia) in 2007. SIGNS AND SYMPTOMS:             The incubation period (the time from exposure to symptoms) of Zika virus disease is estimated to be 3–14 days. The majority of people infected with Zika virus do not develop symptoms. Symptoms are generally mild including fever, rash, conjunctivitis, muscle and joint pain, malaise, and headache, and usually last for 2–7 days. TRANSMISSIONS :            Zika virus is primarily transmitted by t

 Everybody knows siruvani water is the sweetest water in  Tamilnadu.... But how many of us know it is the world's second sweetest water..?             S iruvani Waterfalls[1] and the dam named after them are located 36 km (22 mi) west of Coimbatore in the Western Ghats. The reservoir at Siruvani was built for Tamil Nadu by the Kerala government with funds collected by the Tamil Nadu government to meet the drinking water requirements of Coimbatore. The gateways on either side of the road across the dam are typical of the Kerala and Tamil architectural styles.             Siruvani is also home to certain tribals like the Mudugars and Irulars. The view from the falls and the dam is a tourist attraction. The sweetness has been attributed to the vegetation and rocks through which the water flows in the Attapady area. CONSTRUCTION:-          The government gave its approval for construction of the `masonry gravity' dam in February 1915; work did not start immediately; if one correlat

MOST TOUGHEST EXAMINATIONS

GAOKAO :       Gaokao is a college entrance exam in China and is infamous as one of the top 10 toughest exams in the world. Due to its difficulty level, some European and American universities have also started to accept Gaokao scores. I IT-JEE (Indian Institute of Technology Joint Entrance Examination):        As the entrance test for Engineering courses at Indian Institute of Technology (IIT), the JEE is an exam that most certainly breathes the meaning of the word ‘tough’. For JEE, around 10 lakh applicants registered in 2019 and only 13376 seats were available at the IITs. Acceptance rates hover around a meagre 1%. UPSC (Union Public Services Commission):         The Indian Government conducts the UPSC examination to fill the posts across varied departments such as the Indian Administrative Service, Indian Foreign Service, Indian Revenue Service, etc. It consists of three impassable levels. UPSC also conducts the IES exam for the recruitment of engineers in the government department

"BOILING RIVER"

          T he Shanay-Timpishka , also known as La Bomba, is a tributary of the Amazon River, called the " only boiling river in the world" .It is 6.4 km (4.0 mi) long. It is known for the very high temperature of its waters—from 45 °C (113 °F) to nearly 100 °C (212 °F). The name means 'boiled by the heat of the sun', though the source of the heat is actually geothermal. Location:-            The river is located in the Mayantuyacu sanctuary, part of the Huánuco high forest. The area is inhabited by an Asháninka community.[2] Local shamans believe that the boiling water is birthed by Yucamama, a giant serpent spirit known as the " Mother of the Waters . Investigations:-             Andrés Ruzo, a geothermal scientist, has investigated the source of the heat. According to the experts he spoke to, the answer was a unanimous "no" - after all, hot rivers do exist, but they're generally associated with volcanoes, and there are no volcanoes in that part

GREEN FUNGUS SYMPTOMS, PREVENTION

Image
      T he first case possibly of green fungus infection linked to Covid-19 has been reported in Madhya Pradesh in a person who had recovered from the viral infection. The report comes amid the continuing fear of Covid-19 patients being hit by the dreaded black fungus infection, or mucormycosis.       The patient was found to have Green Fungus (Aspergillosis) infection in his sinuses, lungs and blood, a first ever case reported in India. What is Green Fun gus?        Green Fungus is Aspergillosis, an infection caused by Aspergillus, a common mold (a type of fungus) that lives indoors and outdoors. The infection may cause high fever and nose bleeding. Green fungus is also suspected to cause severe weight loss and weakness.          However, AIIMS Director Randeep Guleria has also said that it is better to identify mucormycosis by its name rather than by the colour.Dr VP Pandey, HoD medicine department, MGM said, “There is no colour coding of fungal infection. The only thing is that it
