Current Affairs Quiz - April, 2019

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.

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:
A site containing the 220-million-year-old fossilized remains of nearly a dozen dinosaurs has been discovered in western Argentina. According to Argentinian paleontologist Ricardo Martinez of the University of San Juan, there are almost ten different individuals, with practically no sediment. The discovery is doubly important because there are at least 7 or 8 individuals of dicynodonts, the ancestors of mammals, the size of an ox. There were also remains of archosaurs, reptiles that could be the ancestors of great crocodiles. The find was discovered in September 2018 in San Juan province, about 1,100 kilometres west of Buenos Aires. The site is between one and two metres in diameter and about the same depth, leading scientists to speculate it was a former drinking hole at a time of great drought, and the creatures died of weakness at the spot. Argentina has been a rich source of fossils from the Triassic, Jurassic and Cretaceous eras over the years – of most creatures not found in the northern hemisphere.

Notes:
Two Indian Navy warships – the stealth guided missile destroyer INS Kolkata and tanker INS Shakti – will participate in the International Fleet Review (IFR) as part of 70TH Anniversary celebrations of PLA (Navy) at Qingdao, China on 23 April, 2019. IFR is a parade of naval ships, aircraft and submarines, and is organised by nations to promote goodwill, strengthen cooperation and showcase their organisational capabilities. IFR also serves as an ideal platform for world’s navies to showcase their prowess and indigenous ship designing and ship building capabilities in a global/ international arena.
