Notes:
Swiss-based NRI scientist Dr Rajendra Joshi, who belongs to Rajasthan, has been conferred with the 2019 Pravasi Bhartiya Samman Award (PBSA) by the President of India Ram Nath Kovind. Dr Joshi is honoured for his outstanding achievement in the field of Science and in recognition of his valuable contribution in promoting the honour and prestige of India and in fostering the interests of Overseas Indians. He is mainly credited with developing path-breaking medicine Tecfidera (BG12) for multiple sclerosis. The theme of 2019 Pravasi Bharatiya Divas convention was ‘Role of Indian Diaspora in building New India.’

Notes:
The Hongkou district of Shanghai has recently claimed to have the world’s first district with 5G coverage and a broadband gigabit network. It conducted trial runs of the 5G network, backed by telecom services provider China Mobile. Shanghai also aims to build over 10,000 5G base stations by the end of this year and the number of 5G base stations could cross 30,000 in 2021. 5G is the next generation of cellular technology with download speed 10 to 100 times faster than the 4G LTE networks.

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:
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:
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:
In India, the NuGen Mobility Summit 2019 will be organized by the International Centre for Automotive Technology (ICAT) at Manesar, NCR, from 27th to 29th November 2019. The purpose of the Summit is to share new ideas, learnings, global experiences, innovations and future technology trends for faster adoption, assimilation and development of advanced automotive technologies for a smarter and greener future. This event will help in building a platform for bringing together all stakeholders in the automotive industry to understand global advancements in technologies. More than 2500 participants and over 250 exhibitors are expected to take part in the Summit.

Notes:
Phayeng Village of Manipur has been tagged as the India’s first carbon-positive settlement. As part of the carbon-positive village project, Phayeng will receive a grant of Rs10 crore in phases to facilitate afforestation in the catchment of river Maklang that flows along the village. The fund will also be utilised for creation of water bodies, introduction of climate change-resilient varieties of crops, installing solar lights, for setting up a community piggery and poultry farm, an eco-resort, replacing firewood in kitchen with cooking stoves and an indigenous knowledge centre in the village. A village is given the Carbon-Positive Tag if it sequesters more carbon than it emits, slowing the accumulation of greenhouse gases and mitigating the effects of climate change. Phayeng is a scheduled caste village of the Chakpa community in Imphal West district and its conservation efforts are mainly linked to the belief that the forest is a sacred grove. It is surrounded by three densely forested hillocks with fruit trees at centre and a stream flowing through it.

Notes:
