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:
Google has introduced a new open platform called Anthos to run and manage apps from anywhere. It is based on the Cloud Services Platform and would let users run applications on existing on-premise hardware investments or in the Public Cloud. Anthos not only allows customers to deploy Google Cloud in their own data centres but also gives them the flexibility to build, run and manage their workloads within their data centre, on Google Cloud, or other cloud providers (Multi-Cloud), without making any changes. Anthos will also let users manage workloads running on third-party clouds like Amazon AWS and Microsoft Azure.

Notes:
The scientists at University of Edinburgh have discovered a new state of physical matter – which allows atoms to exist as both solid and liquid at the same time. Until now, atoms in physical matter were understood to exist typically in one of three states — solid, liquid or gas. An international team of physicists have found that some elements can take on the properties of both solid and liquid states, when subjected to extreme conditions. They used Artificial Intelligence (AI) to simulate what would happen if potassium was subject to huge pressure — between about 200,000 and 400,000 times atmospheric pressure — and heat — between 400 to 800 Kelvin (260 to 980 degrees Fahrenheit). The study found that under these conditions potassium atoms entered what is known as a chain-melted state, where one of the two lattices — the “guest” part — dissolved into liquid, while the “host” part remained solid. They found that more than half a dozen other elements, including sodium and bismuth, were able to reach the state if they were put into the right environments.

Notes:
Harsheel Dani from India has clinched the 2019 Dutch International badminton title at Hague in Netherlands. In the final, he defeated Mads Christophersen of Denmark by 15-21, 21-12, 21-13.

Notes:
The Defence Research and Development Organisation (DRDO) has recently successfully test fired the underdevelopment long range subsonic cruise missile ‘Nirbhay’ from launch complex-3 of the Integrated Test Range (ITR) at Chandipur, Odisha. It has a operational range of 1000 km and can fly very low to the ground to avoid detection by enemy radar called terrain hugging capability. The state-of-the-art missile is the India’s first indigenously designed and developed long-range sub-sonic cruise missile. It is capable of loitering and cruising at 0.7 Mach at altitude as low as 100 metre and covered the designated target range in 42 minutes and 23 seconds.

Notes:
UN cultural experts have recently offered to help in rebuilding the iconic structure of the famed Notre Dame cathedral in Paris. The cathedral is a universal symbol and the centre of France and its devastation has left people across nations shocked. UNESCO World Heritage Centre Director Mechtild Rossler said that the Cathedral is part of the World Heritage site officially known as “Paris, Banks of the Seine”, inscribed on the World Heritage List, in 1991’. The Notre Dame represents a historically, architecturally, and spiritually, outstanding universal heritage. It is also a monument of literary heritage. The cathedral, where construction began in the 1160s extending for more than a century, is considered to be the finest example of the French Gothic style of architecture, with its groundbreaking use of rib vaults and buttresses, stained glass rosettes and sculpted ornaments.

Notes:
In Bangladesh, the historic Mujibnagar has recently celebrated on April 17, 2019. The day marks the oath taking ceremony of Bangladesh’s first government in 1971 at Baidyanathtala in Meherpur. On this day in 1971, senior leaders of the liberation movement of Bangladesh had assembled at Baidyanathtala to form the provisional government of independent Bangladesh. Bangabandhu Sheikh Mujibur Rahman was declared the President in absentia as he was arrested and flown to Pakistan after the Pakistan military crackdown on the then ‘East Pakistan’ on the night of March 25, 1971. The day is being observed by political parties and social and cultural organisations through various programs across Bangladesh.

Notes:
The World Haemophilia Day (WHD) is observed every year on April 17 to increase awareness of haemophilia and other inherited bleeding disorders. The 2019 theme ‘Outreach and Identification’, encourages people to meet and connect with other people who have had similar experiences, and what it is like.It will be observed with the slogan – ‘Reaching Out: The First Step to Care’. Haemophilia is an inherited genetic disorder that impairs the body’s ability to form clots. This condition is dangerous as it can cause excessive loss of blood in case of injuries, easy bruising, and also bleeding between joints and in the brain. Haemophilia can only be managed but does not have a cure.

Notes:
The Institute for Development and Research in Banking Technology (IDRBT), an arm of Reserve Bank of India (RBI), has launched a 5G Use Cases Lab for banking and financial sector. The use of 5G will change a range of technologies and applications including point of sale machines in the banking sector which were now using 2G . The 5G lab will develop and domesticate 5G use cases and set up a research and development experience platform for banking and financial services. It will also collaborate with various stakeholders including banks, government and financial institutions for 5G promotion and absorption of best practices.

Notes:
Dr SK Shivakumar, the renowned space scientist and former Indian Space Research Organisation Satellite Center (ISAC) director, has passed away in Bengaluru on April 14, 2019. He was part of the team that developed the telemetry system for Chandrayaan-I – India’s first lunar exploration mission. A native of Mysuru, he was responsible for designing deep space communications equipment. He was involved in the development of the 32-metre dish antenna that can communicate with satellites millions of miles away.
