Equal Contrast Technique (ECT):
Scientists developed a new methodology, called Equal Contrast Technique (ECT), to analyse Sun images in white light, which can help prevent temporal and latitudinal variations in observations related to instrument and sky conditions.
- It is known that there are large numbers of regions of weak magnetic field on the sun, which vary with time.
- These can be studied using magnetograms and Ca-K line images of the sun, as there is a strong correlation between the magnetic field and the Ca-K line intensity of the region on the Sun.
- The magneto-grams are available for short periods, and the characteristics of the instrument change with time.
- Ca-K line images have been available for a long period at Kodaikanal Observatory (KO), for more than 100 years, with no change in the optics of the instrument.
- Similarly, other observatories in the world, such as Mount Wilson Observatory (MWO) have had this type of data for about 70 years.
- Using the data obtained at Kodaikanal observatory, the scientists have shown that the correlation between derived plage area (the bright region in the sun’s chromosphere) from the Ca-K images and sunspot number is excellent, even on a daily basis, over a period of about 100 years for the first time.
- This type of accurate analysis of the historical time series of Ca-K images can be useful for reliable and accurate investigation of variations on the sun and the effect of this on the climatic condition of the earth.
- It helps in understanding the dynamics of the sun, solar cycle variations, dynamo processes in the convection zone and resulting long-term climatic variations on the earth.

The Tamil Nadu Chief Minister revived the debate over the Katchatheevu, a longstanding point of contention between India and Sri Lanka, particularly with regard to fishing rights and sovereignty over the uninhabited island.
- Katchatheevu is a 285-acre uninhabited speck in the Palk Strait, between India and Sri Lanka, an island located about 14 nautical miles off Rameswaram,India.
- In 1974, Prime Ministers Indira Gandhi of India and Sirima R.D. Bandaranaike of Sri Lanka signed an agreement that recognized Katchatheevu as part of Sri Lanka’s territory, resulting in a change of ownership.
- The agreement also allowed Indian fishermen to fish around the island, dry their nets on it, and permitted Indian pilgrims to visit the Catholic shrine located on the island.
- Fisherfolk from both India and Sri Lanka have historically used Katchatheevu for fishing. Though this feature was acknowledged in the 1974 agreement, the supplemental pact was signed in 1976.
- The 1976 agreement was aimed at defining maritime boundaries and exclusive economic zones for both countries, while also imposing restrictions on fishing vessels and fishermen from either nation, prohibiting fishing in each other’s waters without explicit permission from either of the two countries.
- The Indian government, in 2013, stated that the question of retrieval did not arise as no Indian territory was ceded.
- The issue was framed as a dispute between British India and Ceylon (now Sri Lanka), resolved through agreements in 1974 and 1976.
- The Union government asserted that Katchatheevu lies on the Sri Lankan side of the India-Sri Lanka International Maritime Boundary Line.
A project called Worldcoin has been launched by OpenAI, an Artificial intelligence company. The project claims to be building the world’s largest identity and financial public network.
- Project Worldcoin is an initiative to create a digital network in which everyone can claim some kind of stake, and join the digital economy.
- The initiative uses a device called “Orb” to collect biometric (iris) data and help participants get a World ID through the World app.
- With the app, participants can collect a cryptocurrency called Worldcoin [WLD].
- Users need to be willing to scan irises and/or get their own irises scanned to make the Worldcoin network possible.
- Those who have their irises scanned and collect a World ID can use this to claim the WLD crypto, which they may use for transactions (if possible and legal) or hold on to the asset in the hope that its price might rise.
- Worldcoin claims that using biometric information to avoid duplication is a valid method for including everyone in its network.
- This process is called “proof of personhood” and makes sure that people do not sign themselves up multiple times in exchange for crypto.

Dr. Calyampudi Radhakrishna Rao: Statistician
Dr. Calyampudi Radhakrishna Rao, the world-renowned statistician who pioneered several fundamental statistical concepts, passed away at the age of 102 (22th August 2023).
- C.R. Rao was born on September 10, 1920, in Bellary district, Karnataka in a Telugu family.
- He pioneered several fundamental statistical concepts such as the Cramer–Rao inequality and Rao–Blackwellization.
- Cramer-Rao lower bound, provides a means for knowing when a method for estimating a quantity is as good as any method.
- Rao–Blackwellization provides a means for transforming an estimate into a better—in fact, an optimal—estimate. Together, these results form a foundation on which much of statistics is built.
- The Rao-Blackwell process has been applied to stereology, particle filtering, and computational econometrics, among others, while the Cramer-Rao lower bound is of great importance in such diverse fields as signal processing, spectroscopy, radar systems, multiple image radiography, risk analysis, and quantum physics.
- Dr. Rao was awarded India’s highest honours the Padma Bhushan and Padma Vibhushan in 1969 and 2001, respectively.
