Current Affairs Quiz - April, 2019

Notes:
Astronomers have captured the first-ever image of a black hole, which is located in a distant galaxy known as ‘Messier 87’ (M87), through a network of 8 linked radio telescopes known as the Event Horizon Telescope (EHT) Collaboration. The black hole in the centre of M87 has a mass of more than six billion solar masses. The picture shows an intensely bright ‘ring of fire’ surrounding a perfectly circular dark hole. MIT Computer scientist Dr. Katie Bouman has been credited for developing an algorithm that allowed the world to see what a black hole actually looks like. The EHT is a consortium of more than 200 scientists that has been in the works for about two decades. The EHT telescope achieved the necessary firepower by combining data from 8 of the world’s leading radio observatories, including the Atacama Large Millimetre Array (Alma) in Chile and the South Pole Telescope and created an effective telescope size of the Earth. Black holes were first predicted by Einstein’s theory of relativity and now, the first black hole photo confirms his theory. A black hole is a region of space whose mass is so large and dense that not even light can escape its gravitational attraction.

Notes:
Bibhu Kalyan Nayak from Bhubaneswar has become the first Indian to be appointed Chair of International Hockey Federation (FIH) Health and Safety Committee by the world governing body. He will serve a two-year term lasting till the first executive board meeting after Congress 2020. He has extensively trained in Sports Traumatology and Sports and Exercise Physiology from National Institute of Sports Medicine at Havana, Cuba & National Sports Centre at Madrid, Spain. Nayak also served as a medical officer for the 2018 Men’s World Cup. He was commissioned in the Army Medical Corps of the Indian Army in 1995 and has worked in the Army Sports Institute, Pune for six years.

Notes:
The World Allergy Week (WAW) is an annual initiative of the World Allergy Organization (WAO) to raise awareness of allergic disease and related disorders and advocate for the provision of training and resources in the diagnosis, management, and prevention of these diseases and asthma, which are rising in prevalence around the world. The 2019 theme is “The Global Problem of Food Allergy”. In 2019, the WAW ran from 7th to 13th April and the focus area was food allergy.

Notes:
China has successfully tested the world’s first armed amphibious drone boat ‘Marine Lizard’ in Wuhan, capital of Central China’s Hubei Province. Built by Wuchang Shipbuilding Industry Group under China Shipbuilding Industry Corporation (CSIC), the drone ship could be used in land assault operations and is capable of forming a combat triad with aerial drones and other drone ships. The Marine Lizard can be remotely controlled via satellites and have a maximum operation range of 1,200 kms. It possesses the capability of forming a combat triad with aerial drones and other drone ships. The Marine Lizard’s payloads include an electro-optical system and a radar system. In the weapon department, it is equipped with two machine guns and a vertical launching system for anti-ship and anti-aircraft missiles. This amphibious drone boat can autonomously sail, avoid obstacles and plan routes.

Notes:
Researchers at the IIT Roorkee have identified a new method to detect two of the worst forms of cancer in women – breast and ovarian cancer. The research published in the journal, ‘FASEB Bioadvances’ details the use of whole saliva as a body fluid for early detection of breast and ovarian cancers, as opposed to the traditional method of using blood samples. The research team, led by Professor Kiran Ambatipudi from the institute’s biotechnology department, identified certain proteins present in the saliva which act as potential biomarkers indicative of breast and ovarian cancer metastasis.

Notes:
The 8th edition of Home Expo India 2019 began at India Expo Centre and Mart in Greater Noida on April 16. It covers sectors with maximum thrust and growth potential in home decor, furnishing, furniture, flooring and textiles. About 500 companies in permanent marts will be exhibiting their collection under these categories. The 3-day exhibition has been organized by the Export Promotion Council for Handicrafts.

Notes:
Three Indian student teams won awards in NASA’s 25th edition of Human Exploration Rover Challenge 2019 at the US Space and Rocket Centre in Huntsville, Alabama on April 12-13. The team from KIET Group of Institutions in Ghaziabad won the “AIAA Neil Armstrong Best Design Award” in the college/university division. The Mukesh Patel School of Technology Management and Engineering from Mumbai won the “Frank Joe Sexton Memorial Pit Crew Award” in the college/university division. Lovely Professional University from Phagwara, Punjab, won the STEM Engagement Award. Nearly 100 teams took part in the competition, hailing from 23 states, the District of Columbia and Puerto Rico, as well as a record number of countries, including Bangladesh, Germany, India, Mexico, Morocco and Peru. The competition challenges high school and college teams to design, build and test human-powered roving vehicles inspired by the Apollo lunar missions and future exploration missions to the Moon, Mars and beyond.

Notes:
Sri Lanka has launched its first satellite ‘Raavana-1’ into space from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility on Virginia’s East Shore. It weights around 1.05 kg and the lifespan of the satellite is around one and a half years. The launch marks Sri Lanka’s entry into the global space age. Under BIRDS project, the satellite was designed and built at the Kyushu Institute of Technology in Japan by two Sri Lankan research engineers. Its camera mission is to capture images of Sri Lanka and its neighbouring countries.

Notes:
The critically endangered ‘Kakapos’ – the world’s fattest species of parrot – have enjoyed a record breaking breeding season, according to New Zealand’s Department of Conservation (DOC). This year, 76 chicks have been hatched under the DOC’s conservation scheme, with 60 expected to reach adulthood. This will significantly boost the population which has grown to 147 adults since a small number of the plump green, yellow and black birds were discovered in 1970. The kakapo is an “unusual” parrot as the females control the breeding process and only mate every two to four years when their favourite fruit grows in New Zealand’s Rimu trees – the period is known as a “mast year”. New Zealand’s kakapo recovery programme is so tightly monitored that although they remain in the wild, each one has a radio transmitter attached to its body and there are monitoring systems embedded in their nests. It is claimed that kakapo is probably one of the most intensively managed species in the world.

Notes:
By using data obtained by NASA’s Cassini spacecraft, the researchers discovered deep lakes (more than 300 feet, or 100 meters) filled with methane on Saturn’s moon Titan. The team also found “phantom lakes” that fill and empty periodically. It must be noted that Titan is the only known body in our solar system other than Earth with a liquid on its surface. But rather than a water cycle, it has a methane and ethane cycle. The new findings represented further evidence about Titan’s hydrological cycle, with liquid hydrocarbons raining down from clouds, flowing across its surface and evaporating back into the sky. This is comparable to Earth’s water cycle. Titan, with a diameter of 5,150 km, is the solar system’s second largest moon, behind only Jupiter’s Ganymede. It is bigger than the planet Mercury. The research was published in the journal Nature Astronomy.
