Current Affairs Quiz - April, 2019

Notes:
The Japan Aerospace Exploration Agency (JAXA) has said that its Hayabusa2 spacecraft has successfully blasted the surface of an asteroid Ryugu to make a crater on its surface. The move will pave the way for the collection of underground samples for possible clues to the origin of the solar system. For this, the Hayabusa2 dropped a “small carry-on impactor” made of copper onto the asteroid and the spacecraft safely evacuated and remained intact. Now, JAXA is analyzing data to examine if or how the impactor made a crater. The copper explosive is the size of a baseball weighing 2 kg. If successful, it would be the first time for a spacecraft to take such materials. The asteroid, named Ryugu after an undersea palace in a Japanese folktale, is about 300 million kilometers (180 million miles) from Earth. Earlier, Hayabusa2 successfully touched down on a tiny flat surface on the boulder-rich asteroid in February 2019, when the spacecraft also collected some surface dust and small debris.

Notes:
The Bureau of Indian Standards (BIS) has tied up with IIT Delhi to collaborate in the field of standardisation and conformity assessment. Under the MoU, the two have agreed to set-up a Centre of Excellence in the field of Standardisation, Testing and Conformity Assessment with the BIS branding at IIT-Delhi campus. Both have also agreed to appoint a Chair in the field of standardisation and conformity assessment. According to the MoU, IIT Delhi will provide infrastructure support for research and development projects of relevance to standardisation and BIS will provide financial support to IIT Delhi for projects. Initially, the MoU will remain in force for a period of five years and can be extended further.

Notes:
To counter growing Chinese footprint in Indian ocean region, the Indian Navy has initiated the process to acquire six lethal submarines under the ambitious Project-75 India (I). The project would cost Rs 50,000 crore. Under Project 75-India, the Navy wants to build six conventional diesel-electric submarines which would be almost 50% bigger than the under-construction Scorpene class submarines being built at the Mazagon Dockyards Limited in Mumbai. As per the requirements stated by the maritime force, it wants the submarines to be equipped with heavy-duty firepower as it wants the boats to have at least 12 Land Attack Cruise Missiles (LACM) along with Anti-Ship cruise missiles (ASCM).

Notes:
Indian Navy has signed a Memorandum of Understanding (MoU) with Council of Scientific and Industrial Research (CSIR) to undertake joint research and development of advanced technologies for the Indian Navy. This will be a collaborative arrangement between labs of CSIR, the Indian Navy and Indian industry. The MoU would facilitate joint R&D activities in diverse fields of Mechanical, Electronics, Communication, Computer Science, Propulsion systems, Metallurgy and Nanotechnology.

Notes:
Sydney Brenner (92), a South African-born biologist, has passed away in Singapore on April 5, 2019. He helped decipher the genetic code and his research on a roundworm sparked a new field of human disease research. Brenner shared the Nobel Prize in medicine in 2002 for his contribution to work unraveling how genes control cell division. He and two colleagues, John Sulston and Robert Horvitz, traced a transparent roundworm known as C. elegans to determine how cells divide and create something new. The findings on programmed cell death were key to understanding how cancers develop and laid the groundwork for making C. elegans a major model organism in research.

Notes:
The World Bank (WB) has recently released its latest edition of Migration and Development Brief. In it, India has retained its position as the world’s top recipient of remittances with its diaspora sending a whopping $79 billion back home in 2018. India was followed by China ($67 billion), Mexico ($36 billion), the Philippines ($34 billion), and Egypt ($29 billion). Over the last three years, India has registered a significant flow of remittances from $62.7 billion in 2016 to $65.3 billion 2017. According to the report, remittances to low-and middle-income countries reached a record high of $529 billion in 2018, an increase of 9.6% over the previous record high of $483 billion in 2017. Global remittances, which include flows to high-income countries, reached $ 689 billion in 2018, up from $633 billion in 2017.

Notes:
Scientists from University of Michigan in the United States have found that dangerous airborne viruses can be rendered harmless on-the-fly when exposed to ‘cold plasma’ – a stream of energetic, charged fragments of air molecules. The researchers have measured the virus-killing speed and effectiveness of non thermal plasmas – the ionised, or charged, particles that form around electrical discharges such as sparks. A non thermal plasma reactor was able to inactivate or remove from the air stream 99.9% of a test virus. The researchers hope to one day harness this capability to replace the surgical mask.

Notes:
The Indian Institute of Technology-Madras (IIT-Madras) has been ranked as the top institute in the overall category in the latest edition of National Institute Ranking Framework (NIRF) 2019 and is followed by Indian Institute of Science (IISc), IIT Delhi, IIT-Bombay, IIT-Kharagpur, IIT Kanpur, JNU, IIT-Roorkee, IIT-Guwahati and BHU. The NIRF is a Ministry of HRD initiative and released annually. On the other hand, Indian Institute of Management (IIM) Bangalore secured the top spot in the management college ranking followed by IIM Ahmedabad and IIM Calcutta. The National Law School of Indian in Bengaluru grabbed the top spot under the law category while Indian Institute of Technology was ranked first in the Architecture category. All India Institute of Medical Sciences (AIIMS), New Delhi, followed by Post Graduate Institute of Medical Education and Research, Chandigarh and Christian Medical College, Vellore were ranked as the top three medical colleges.

Notes:
The United States has recently designated Iran’s elite military force, Islamic Revolutionary Guard Corps (IRGC), as a Foreign Terrorist Organization (FTO) in accordance with section 219 of the Immigration and Nationality Act of 1965 (INA). The move, which takes effect on April 15, is part of an effort to put maximum pressure on Iran to end its support for terrorist plots and militant activity that destabilizes the Middle East. Meanwhile, Iran has also designated U.S. military bases and their military forces as terrorist bases and terrorist forces in the region. The IRGC is in charge of Iran’s ballistic missile and nuclear programs. It was formed after the 1979 Islamic revolution with a mission to defend the clerical regime.

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.
