Notes:
In tennis, Roger Federer lifted his fourth ATP Miami Open title with an emphatic 6-1, 6-4 win over defending champion John Isner on 31st March 2019 at the Hard Rock Stadium in Miami Gardens, States. It is Swiss player’s 28th Masters title and the 101st overall for a player who has won 20 Grand Slam singles titles.

Notes:
The 13th edition of Earth Hour 2019 was observed on March 30 with theme “#Connect2Earth” to encourage people across the world to turn off non-essential electric lights for one hour from 8:30 to 9:30 p.m. It calls for greater awareness and more sparing use of resources, especially fossil fuels that produce carbon gases and lead to global warming. On this day, the World Wide Fund (WWF) for Nature-India made an appeal to citizens to join the Earth Hour 2019 to inspire millions across the country to shift to more sustainable practices and minimize negative impacts on the planet.

Notes:
The Hump-backed Mahseer, also known as ‘Tor remadevii’ in scientific terms, is a critically endangered species as per the International Union for Conservation of Nature (IUCN). This iconic and highly-valued freshwater fish, termed as the ‘tiger of the water’, inhabits the Cauvery river basin, including Kerala’s Pambar, Kabini and Bhavani rivers. The fish earns its megafauna status by reaching up to a measurement of 1.5m and a weight of 55 kg. Its endangered title also accompanies five other species, including two wild orchids, the Arabian scad, and two wild coffee species exclusive to a few locales in the Western Ghats.

Notes:
Kandhamal Haldi, a variety of turmeric indigenous to southern Odisha, has finally got the Geographical indication (GI) tag from Intellectual Property India. The recognition coincided with the state’s Foundation Day (Utkal Divas). Odisha, on April 1 1936, was carved out as a separate state in the then British India on a linguistic identity. The golden yellow spice is named after the district where it is produced & has been cultivated since time immemorial and is known for its medicinal value. Turmeric is the main cash crop of tribal people in Kandhamal. More than 60,000 families (nearly 50% of Kandhamal population) are engaged in growing the variety. Apart from domestic use, turmeric is also used for cosmetic and medicinal purposes. A GI is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin.

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:
According to a new collaborative study by the Queen’s University Belfast and Aberystwyth University in the UK, the sun’s magnetic field is ten times stronger than previously thought. Using the Swedish one-metre Solar Telescope at Roque de los Muchachos Observatory, in the Canary Islands, David Kuridze studied a particularly strong solar flare which erupted near the surface of the Sun on September 10, 2017. A combination of favourable conditions and an element of luck enabled the team to determine the strength of the flare’s magnetic field with unprecedented accuracy. The researchers believe the findings have the potential to change our understanding of the processes that happen in the Sun’s immediate atmosphere. The study found that the sun’s corona extends millions of kilometres above the surface, measuring 1,400,000 kilometres across — 109 times larger than Earth — and 150,000,000 km from Earth. Solar flares appear as bright flashes and occur when magnetic energy that has built up in the solar atmosphere is suddenly released. These solar flares can lead to storms which, if they hit Earth, form the northern lights — the Aurora Borealis. They can also disrupt communications satellites and GPS systems.

Notes:
Prof. Vikram Patel, a psychiatrist and professor of global health at Harvard Medical School, has won the prestigious 2019 John Dirks Canada Gairdner Global Health Award. Mr. Patel has led research generating knowledge on the burden and determinants of mental health problems in low and middle-income countries and pioneered approaches which utilise community resources for the prevention and treatment of mental health problems in India with global impact. Laureates receive a $100,000 cash honorarium and will be formally presented with their awards on October 24, 2019 at the annual Canada Gairdner Awards Gala in Toronto.

Notes:
In Kerala, the group of science experts of the Hume Centre for Ecology and Wildlife Biology has decided to launch ‘Café Scientifique’ to promote science among public in an interesting way. It is the first such initiative in the state to popularise the subject. It envisages to bring science back into popular culture by demystifying scientific research for the public and empowering non-scientists to comfortably assess science and technology issues, particularly those that impact social policy making. The project is also aimed at making science relevant, powerful and important to the public, especially the younger generations. Here, various topics such as universe, climate change, evolution, genetics and human-animal relations will be discussed in every monthly gathering. It is a grassroots public science initiative based on the French Café Philosophique model.

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.
