Notes:
Using platinum nanocatalyst, a two-member team at the IIT Madras has successfully converted petroleum waste-product toluene into benzoic acid. Benzoic acid is used as a food preservative (E210) and medicine for fungal/bacterial infection. Toluene is converted into benzoic acid through selective and controlled oxidation in the presence of a catalyst — binaphthyl-stabilised platinum nanoparticles (Pt-BNP). Generally, organic reactions are carried out using organic solvents, which makes it expensive and also generates toxic waste. So, the team led by G. Sekar used water as solvent to make it environment-friendly. Also, a green oxidant (70% aqueous tert-butyl hydroperoxide or TBHP) is used for converting toluene into benzoic acid. When toluene is oxidised, it gives four products. But, the team used catalyst that they developed and then only benzoic acid is produced. No alcohol, aldehyde or ester is produced. The yield of benzoic acid varied from 68-96% depending on whether the toluene used is electron-deficient or electron-rich.

Notes:
IIT Kharagpur has signed a Memorandum of Understanding (MoU) with the Pullela Gopichand Badminton Academy (PGBA) to develop research and training module for the trainees of the Hyderabad-based sports facility. The thrust area of the collaboration is to promote health and wellbeing of sportspersons and coaches for enhancing the quality of performance and resilience. Players and coaches from PGBA will benefit from these programs. Further, the coaches will also be trained on how to use that knowledge while training players. Under the collaboration, IIT-KGP will also set up a sports academy in collaboration with Gopichand. The academy would promote collaborative research related to happiness in sports in general and badminton in particular, and science and technology in sports training. The scope would also include joint monitoring and use of materials used in general and badminton in particular by IIT Kharagpur and PGBA. A sum of Rs10 crore has been allocated to develop modern sports facilities at IIT-Kgp.

Notes:
Lewis Hamilton, a British racing driver, has won the 2019 Formula 1 Bahrain Grand Prix tournament after an engine problem hit runaway leader Charles Leclerc’s Ferrari late in the race.

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:
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:
Chicago has created history by electing an African-American woman as its mayor for the first time. Lori Lightfoot is a former federal prosecutor and practicing lawyer who has never before held elected office. She won the city’s mayoral race by a huge margin. She will also be Chicago’s first openly gay mayor. Lightfoot’s primary proposals include increasing access to affordable housing, creating an office of public safety to reduce crime and reform policing, and pushing through a real estate transfer tax to help combat homelessness. She also backs abolishing US Immigration and Customs Enforcement. Lightfoot will take over office from Mayor Rahm Emanuel, who previously served as chief of staff under former President Barack Obama.

Notes:
The Sri Lankan army has decided to conduct its largest ever military exercise titled ‘Exercise Western Shield’ in July 2019 to provide an opportunity for army trainees to march through areas that are not usually accessible to others, except forest conservation authorities. It will see participation of over 5,000 soldiers and will extend from Mannar to Puttalam, including Kalpitiya, Wilpattu National Park, Mavillu and Thabbowa Forest Reserves and the Western coastal belt. The exercise is coincided with 10 years since the end of the island’s 30-year civil conflict between government troops and Tamil Tiger rebels.

The World Health Day (WHD) is observed every year on 7th of April as a global health awareness day under the sponsorship of the World Health Organization (WHO). The day also celebrated the establishment of WHO in 1948. The 2019 theme is “Universal Coverage: Everyone, Everywhere”. Here, Universal Health means that all people across the globe have access, without any kind of discrimination, to comprehensive quality services, wherever they need them, without facing financial difficulties.
