About Pravasi Bharaitya Diwas

• Pravasi Bharatiya Diwas is a day dedicated to the overseas Indian community and celebrated once every two years. This day is celebrated on January 09 by the people of India. The day has its roots from our ‘Father of The Nation,’ Mahatma Gandhi, who was the greatest Pravasi. He returned from South Africa in 1915 and led the Indian freedom movement. Therefore, marking this day, the Ministry of External Affairs (MEA) has celebrated this day since 2003 from January 07-09 every year. This practice will bring together the Indians abroad to enrich knowledge, expertise, and skills to be shared in a common platform.
• This day came into effect in 2003, but in 2015 it was revised and was decided to be celebrated every two years. It was then a theme-based conference that was set up every year during the interim period.
• The conference invited various Indian communities abroad who are experts in their respective fields, policymakers, and stakeholders to come together and participate in the event.
• This day plays a significant role as the overseas Indian community gets a shared platform to get themselves engaged with the government and the native people of the land.

• India’s home-grown testing kit OmiSure, developed by the Tata Medical and Diagnostics (Tata MD) to identify the Omicron variant of Covid-19 in samples taken from the nose and throat, was approved by the Indian Council of Medical Research (ICMR) recently.

About OmiSure

• Apart from identifying the B.1.1.529 (Omicron) variant, the kit can also detect any other circulating SARS-CoV-2 variants.
• The company said the unique test design developed by scientists at Tata MD is a single tube, fully multiplexed test (provisional patent application filed). Therefore, it has two checks in place for Omicron detection without compromising the ability to detect other SARS-CoV-2 variants.
• The kit evaluated in partnership with the ICMR reported 100 per cent sensitivity and 99.25 per cent specificity for detection of variants of SARS-CoV-2, including Omicron.
• OmiSure is the first test to use a combination of two S-gene viral targets to identify Omicron. The first target is based on S-gene dropout or S-gene target failure (SGTF) and the second target is based on S-gene mutation amplification (SGMA).
• The kit developed by a team headed by Bengaluru-based Dr V Ravi, former head of neurovirology, NIMHANS, and currently head of R&D, Tata MD, is listed on the ICMR website as the only kit approved specifically for Omicron detection.

• A group of Indian and international scientists have spotted a peculiar binary star that shows heartbeat but no pulsations contrary to the norm of binary stars of sporting both heartbeats as well as pulsations. This star is called HD73619 in Praesepe (M44), located in the Cancer constellation, one of the closest open star clusters to the Earth.

About star with a heartbeat and without a magnetic field

• A total of about 180 heartbeat stars are known to date. The name ‘Heartbeat’ stems from the resemblance of the path of the star to an electrocardiogram of the human heart. These are the binary star systems where each star travels in a highly elliptical orbit around the common centre of mass, and the distance between the two stars varies drastically as they orbit each other. When the stars are at closest passage of binary systems, a sudden increase in integrated brightness with amplitude of the order of several parts-per-thousand (ppt) is observed. As the components move apart, the light variation falls and finally becomes flat, indicating that combined flux is reduced, resulting in alternating peaks and troughs in their light curves. The pulsational activity of such stars is due to the oscillations in the component stars when they are at their closest approach.
• A team of 33 scientists, led by Dr. Santosh Joshi from Aryabhatta Research Institute of Observational Sciences (ARIES), an autonomous institution under the Department of Science & Technology (DST), Govt of India, carried out analysis of photometric and high-resolution spectroscopic observations of HD73619 obtained using 8 ground-based telescopes located in different parts of the globe. They have found that HD73619 is the first member of heartbeat systems in binary chemically peculiar stars that does not show any pulsational/vibrational activity at their closest approach.

About the announcement made by PM Modi

• This is a fitting tribute to the courage of the Sahibzades and their quest for justice. ‘Veer Baal Diwas’ will be on the same day Sahibzada Zorawar Singh Ji and Sahibzada Fateh Singh Ji attained martyrdom after being sealed alive in a wall.
