Current Affairs Quiz - April, 2019

Notes:
In a major attempt to build resilience against the impact of climate change, the Central Marine Fisheries Research Institute (CMFRI) and the Space Applications Centre (SAC) of ISRO have joined together to map, validate and protect smaller wetlands in the coastal region aimed at restoring them through coastal livelihood programmes. Both the organizations will develop a mobile app and a centralised web portal with a complete database of wetlands that are smaller than 2.25 hectares in the country. Such smaller wetlands cover an area of more than five lakh hectares across the country, while Kerala having as many as 2,592 smaller wetlands. As per the MoU, the two scientific institutes aim to identify and demarcate wetlands and restore the degraded wetlands through suitable livelihood options like coastal aquaculture. The app will be used for real-time monitoring of the wetlands and giving advisories to stakeholders and coastal people. The collaborative move is part of a national framework for fisheries and wetlands recently developed by the National Innovations in Climate Resilient Agriculture (NICRA) project of CMFRI.

Notes:
The International Day of Human Space Flight is observed every year on April 12 to mark the beginning of the space era for mankind, reaffirming the important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of States and peoples, as well as ensuring the realization of their aspiration to maintain outer space for peaceful purposes. On 12th April 1961 the first human space flight was carried out by Yuri Gagarin, a Soviet citizen. This historic event opened the way for space exploration for the benefit of all humanity.

Notes:
Pradeep Choubey (70), the renowned Hindi poet, has passed away in Gwalior, Madhya Pradesh on April 12, 2019. He was the younger brother of celebrated humorist, satirist and poet Shail Chaturvedi. Born on 26th August 1949 in Maharashtra’s Chandrapur district, Choubey shifted to Gwalior. He quit his job at Dena Bank to pursue his passion of poetry and travelled across the nation enthralling audiences with his punches, several of them targeted at the orthodox elements of society. Besides humour, he was famous for satirical comments on the system.

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:
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 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:
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.

Notes:
The World Heritage Day (WHD) is celebrated every year on April 18 to promote the cultural heritage across the world. The 2019 theme is ‘Rural Landscapes’. It is also a day of international solidarity in favor of strengthening and safeguarding heritage world-wide. The day also aims to seek recognition for the people involved in preserving the sites, especially scientists, archaeologists, geographers and engineers. As of 2018, India has 36 World Heritage Sites including Western Ghats, Sundarbans National Park, Taj Mahal, City of Ahmadabad, Nalanda University, Mahabodhi Temple in Bihar and Khajuraho in Madhya Pradesh.

Notes:
The researchers at Tel Aviv University have successfully “printed” the world’s first three dimensional (3D) vascularised engineered heart using a patient’s own cells and biological materials to completely match the immunological, cellular, biochemical, and anatomical properties of the patient. Their findings were published in a study in Advanced Science. Until now, scientists in regenerative medicine have been successful in printing only simple tissues without blood vessels. But the latest feat is the first time scientists have created a complex organ with biological materials. The process of creating the 3D printed heart started with a biopsy of fatty tissue taken from patients. The cellular material from the tissues was used as the ” bionic ink” for the print job. That allowed researchers to create complex tissue models including cardiac patches and eventually an entire heart. The proof-of-concept feat could pave the way for a new type of organ transplant.

Notes:
A book containing English translation of the 100-year-old classic Punjabi poem about Jallianwala Bagh massacre, ‘Khooni Vaisakhi’ has been released in Abu Dhabi. India’s Ambassador to the UAE Navdeep Singh Suri has commended the launch of a book containing English translation of the Punjabi poem. The poem was translated by Mr Suri whose grandfather, revolutionary poet and novelist Nanak Singh, a Jallianwala Bagh survivor, wrote it after witnessing first-hand the events of April 13, 1919. On this ill-fated day, British troops fired upon crowds of protesters peacefully demonstrating against the Rowlatt Act of the British Raj, leading to the loss of well over a thousand lives. The book was also released in New Delhi on 13th April 2019, marking 100 years since the Jallianwala Bagh massacre that took place in Amritsar.
