Current Affairs Quiz - April, 2019

Notes:
The Hongkou district of Shanghai has recently claimed to have the world’s first district with 5G coverage and a broadband gigabit network. It conducted trial runs of the 5G network, backed by telecom services provider China Mobile. Shanghai also aims to build over 10,000 5G base stations by the end of this year and the number of 5G base stations could cross 30,000 in 2021. 5G is the next generation of cellular technology with download speed 10 to 100 times faster than the 4G LTE networks.

Notes:
The Government of India (GoI) has constituted a tribunal to adjudicate if there exists sufficient cause to ban the Jamaat-e-Islami Jammu and Kashmir (JeL) and the Jammu and Kashmir Liberation Front-Yasin Malik (JKLF-Y) faction. The tribunal will be headed by Justice Chander Shekhar of the Delhi High Court. The decision has been taken by the Union Home Ministry exercising the powers conferred under the Unlawful Activities (Prevention) Act of 1967. The JeI and the JKLF-Y were declared as unlawful associations on February 28 and March 22 respectively.

Notes:
Former world champion, Viktor Axelsen of Denmark has won the men’s singles title at the 2019 Yonex-Sunrise India Open badminton tournament on March 31. In the final, he defeated Kidambi Srikanth by 7-21, 20-22 in New Delhi. This was Srikanth’s fourth defeat to Axelsen in five encounters since March 2017. And also, it was Srikanth’s first final in a BWF world tour event in 17 months. He had last won a title at the 2017 French Open.

Notes:
Researchers led by Kavli Institute for the Physics and Mathematics of the Universe in Japan has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. They used the gravitational lensing effect to look for primordial black holes between Earth and the Andromeda galaxy. However, gravitational lensing effects are very rare events because it requires a star in the Andromeda galaxy, a primordial black hole acting as the gravitational lens, and an observer on Earth to be exactly in line with one another. In order to maximise the chances of capturing an event, the researchers used the Hyper Suprime-Cam digital camera on the Subaru telescope in Hawaii, which can capture the whole image of the Andromeda galaxy in one shot. Taking into account how fast primordial black holes are expected to move in interstellar space, the team took multiple images to be able to catch the flicker of a star as it brightens for a period of a few minutes to hours due to gravitational lensing. The team’s results showed primordial black holes can contribute no more than 0.1% of all dark matter mass. Therefore, it is unlikely the theory is true.

Notes:
India has recently signed an agreement with National Bank for Agriculture and Rural Development Consultancy Service (NABCONS) for setting up India-Africa Institute of Agriculture and Rural Development (IAIARD) in Malawi. The agreement is a part of India’s efforts to enhance capacity in the areas of agro-financing and entrepreneurship development for African countries. IAIARD will be a Pan-African Institute wherein trainees not only from Malawi but also from other African countries, will receive training to develop their human resources and build their capacity. The entire expenditure on faculty from India, the travel, logistics and training course expenses for students from other African countries will be borne by the Government of India (GoI) for an initial period of 3 years. This institute will be the first of its kind developed in an African country by India. This will further strengthen the bilateral relations with Malawi and India’s relations with African Union.

Notes:
The Indian Army has constructed the 260 feet long cable-suspension bridge ‘Maitri Bridge’ over Indus river at Choglamsar village in Leh in a record time of 40 days. It is the longest suspension bridge over the river and is built by combat engineers of the ‘Sahas aur Yogyata’ regiment of the Indian Army’s ‘Fire and Fury Corps’. The name of the bridge, “Maitri”, is meant to symbolise the amity and solidarity between soldiers and locals. The bridge is expected to improve connectivity in remote regions of Leh and Ladakh. It will connect the remote areas of Choglamsar, Stok and Chuchot, which are said to be the largest villages in the region.

Notes:
In India, the NuGen Mobility Summit 2019 will be organized by the International Centre for Automotive Technology (ICAT) at Manesar, NCR, from 27th to 29th November 2019. The purpose of the Summit is to share new ideas, learnings, global experiences, innovations and future technology trends for faster adoption, assimilation and development of advanced automotive technologies for a smarter and greener future. This event will help in building a platform for bringing together all stakeholders in the automotive industry to understand global advancements in technologies. More than 2500 participants and over 250 exhibitors are expected to take part in the Summit.

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:
Chinese scientists have discovered a possible “death switch” mechanism in plant’s immune system that triggers infected cells to self-destruct, thus limiting the spread of the disease and keeping other parts of the plant healthy. This is as per the findings published in the journal ‘Science’. The discovery provides clues to cell death control and immunity for plants. The researchers hope further research can lead to a new generation of disease-resistant crops that use significantly less pesticide and are more environmentally friendly. The research was done by scientists from Tsinghua University and the Chinese Academy of Sciences’ Institute of Genetics and Development Biology. The ‘death switch’ is usually harmless to the plant because it only affects diseased cells, which are a tiny portion of the entire plant.
