Notes:
Indian captain Virat Kohli has been named as the Leading Cricketer of the year for an unprecedented third year in a row by the 2019 edition of Wisden Cricketers’ Almanack. Kohli was picked as one of the Wisden’s Five Cricketers of the Year, along with Tammy Beaumont, Jos Buttler, Sam Curran and Rory Burns. The Indian skipper is only the third cricketer ever to have won the award more than three times after Don Bradman (10 times) and Jack Hobbs (8 times). India’s Smriti Mandhana has been named as the women’s Leading Cricketer in the World for 2018 while Afghanistan spinner Rashid Khan was named the Leading Twenty20 Cricketer for the second consecutive year. Wisden has been listing out Cricketers of the Year since 1889 and it is considered as one of the more prestigious awards in the sport.

Notes:
The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the lab. However, researchers have now developed a spectrometer so small and simple that it could integrate with the camera of a typical cellphone without sacrificing accuracy. The device also has an advanced capability called hyperspectral imaging, which collects information about each individual pixel in an image to identify materials or detect specific objects amidst a complicated background. Hyperspectral sensing could be used to detect seams of valuable minerals within rock faces or to identify specific plants in a highly vegetated area.

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:
Rio Paralympics silver medallist Deepa Malik has been named the recipient of the New Zealand Prime Minister’s Sir Edmund Hillary Fellowship for 2019 in recognition of her inspiring achievements. She will travel to New Zealand as a Sir Edmund Hillary Prime Minister’s Fellow and meet with Prime Minister Jacinda Ardern as well as visit Paralympic sporting organizations. Here, she will work to promote sporting, cultural as well people-to-people relationship between India and New Zealand. Till date, she has won 58 national and 23 international medals and has been honoured with the Padma Shri and Arjuna Award. Deepa won the silver in shot put F53 event in 2016 Rio Paralympics. Athletes in F53 category can do only seated throws and they have full muscle power on their shoulder, elbow and wrist in the throwing arm. She recently joined the Bharatiya Janata Party (BJP).

Notes:
Scientists have recently discovered new species of ancient human excavations in Philippines. This newly identified species named Humo Luzonensis after Luzon Island, where bones and teeth from individuals of this species were excavated from Callao Cave. The small size of the bones suggests this archaic human would have been shorter than 4ft tall – possibly even shorter than another ancient species – Homo floresiensis. The specimens of H. luzonensis were dated to 50,000 and 67,000 years old (Late Pleistocene period), which suggests that the species was alive at the same time as several other hominins belonging to the genus Homo, including Homo sapiens, Neanderthals, Denisovans and Homo floresiensis. Thus, this discovery claims finding to be the earliest direct evidence human presence in Philippines.

Notes:
India will be the Guest of Honour country at the 29th Abu Dhabi International Book Fair (ADIBF 2019), which is scheduled to be held from April 24th to 30th.

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.

It also houses a special bird’s kitchen and healthcare centre. Some of the key attractions in the park are Ostriches, African grey parrots, Blue gold macaws, Toucans, Black swan and Rainbow lorikeet among others.

Notes:
Researchers at the IIT Roorkee have identified a new method to detect two of the worst forms of cancer in women – breast and ovarian cancer. The research published in the journal, ‘FASEB Bioadvances’ details the use of whole saliva as a body fluid for early detection of breast and ovarian cancers, as opposed to the traditional method of using blood samples. The research team, led by Professor Kiran Ambatipudi from the institute’s biotechnology department, identified certain proteins present in the saliva which act as potential biomarkers indicative of breast and ovarian cancer metastasis.
