Low-cost test on anvil to detect life-threatening pregnancy complication of preeclampsia: expert
Preeclampsia is a serious pregnancy complication, characterised by high blood pressure and kidney damage. It can endanger both the mother and the baby and, if left untreated, can progress to eclampsia, a life-threatening condition, according to S. Ananth Karumanchi, director of Renovascular Research Centre, Cedars-Sinai, Los Angeles, the U.S.
Dr. Ananth was in Visakhapatnam to deliver the Dr. GRK Raju Oration at the valedictory event of Waves 2025, the FOGSI Presidential Conference on Sunday (May 18).
'Preeclampsia affects both the mother and baby owing to high BP, and it can turn fatal for the mother. We have discovered molecules in blood that can be identified to detect the triggers of preeclampsia much before its onset. At present, the disease is being detected only after complications like high BP set in, affecting body organs. This new molecular test gives a much higher degree (92%) of accuracy than conventional tests,' Dr. Ananth told The Hindu on the sidelines of the conference.
'The molecular test has been approved by the US FDA and is being used in the U.S. and Europe. It's, however, very expensive right now. We are in the process of developing a low-cost test, and a study is being done in Delhi to validate the low-cost version. Once this gets approved, it can be a game changer to prevent the complications of preeclampsia in pregnant women and thereby bring down the Maternal Mortality Rate (MMR) and Infant Mortality Rate(IMR) in developing countries,' he opines.
On new therapies to combat eclampsia, Dr. Ananth says: 'As the pathway for early detection of preeclampsia has been found, we are in the process of developing RNA interference therapy, which can be given as a single dose during pregnancy.'
'An estimated 15% of maternal deaths during pregnancy in the world and 25% of [such] deaths in India are caused by preeclampsia. MMR [maternal mortality rate] is 93 in India and 45 in A.P.,' says T. Radha, the organising chairperson of the conference who had invited Dr. Ananth to update all the practitioners on the latest research on preeclampsia.
'After completing MBBS in Kilpauk Medical College in Chennai, Dr. Ananth pursued higher studies at Harvard University and later completed his Fellowship in Nephrology at Beth Israel Deaconess Medical Center in Boston. His path breaking research will usher in a paradigm shift in the management of hypertensive disorders of pregnancy and provide solace to millions of pregnant women,' added Dr. Radha.

AI-based initiative for education improves results in Tonk's government schools
'Padhai with AI', an artificial intelligence (AI)-based initiative launched with the objective of helping out students in difficult subjects, has extended the benefits of digital learning and improved the results of government schools in Rajasthan's Tonk district. In the first academic session of its execution, 95% of secondary students have passed out with flying colours. The initiative has helped the students struggling with tough subjects, especially mathematics, in solving questions from their textbooks and practising new questions of a similar pattern. The digital learning has combined technology with education through a dedicated web portal, which includes remedial practices, drills and personalised learning. Tonk Collector Saumya Jha came up with the AI-based solution after realising the challenges in the performance of students during her field visits to schools in the district, situated south of Jaipur. Ms. Jha interacted with the teachers to identify fear and anxiety about mathematics as an important factor affecting the students. 'We introduced 'Padhai with AI' programme with a web portal and prepared a detailed action plan for three months in the academic session for the students of 10th class, setting the targets for 2025,' Ms. Jha told The Hindu. A total of 351 government schools were selected for the initiative. 'Improvement in maths' After the results were declared in May, it was found that the percentage of students who passed in Tonk was higher than the State average. There was also an increase of 5% in the number of students passing in the first division. 'An impressive jump was witnessed in the performance in mathematics, which was earlier a dreaded subject for children,' Ms. Jha said.

Bangalore University set to give life and health insurances to students on Jnana Bharati campus
In a unique move, Bangalore University has decided to provide life insurance and health insurance to all students studying on its Jnana Bharathi campus. A decision to this effect was taken in the recent syndicate meeting of the university. The decision will be implemented from the academic year 2025-26. There are a total of 54 departments related to various undergraduate, postgraduate, and Ph.D. programs, and more than 4,000 students, on the Jnana Bharathi campus. Additionally, the syndicate has directed that all students of the university's affiliated colleges should be registered for insurance under the Pradhan Mantri Jan Suraksha Yojana. Why the initiative Most students studying at Bangalore University are from rural areas and belong to economically and socially weaker sections. Two major roads pass through the Jnana Bharathi campus: one from Mysuru Road towards Ullal and the other from Nagarbavi towards Kengeri. These roads are consistently congested with traffic, and accidents are frequent; as a result, students are often injured in these incidents. A postgraduate student died in a bus accident two years ago. When any such accident occurs, compensation is provided to the students and their parents from the university's funds, which the insurance will now cover. Decision in 2017 Bangalore University had decided to provide health insurance to all its students in 2017. It had also formed an expert committee in this regard. The committee had discussed and submitted a report on the total premium amount of health insurance, including the student's share and the university's share. But it was not implemented. However, there was a demand from students for health insurance. Students were registered under the 'Ayushman Bharat' scheme in 2024-25, and Ayushman cards were issued. However, as there is limited coverage under this scheme, the university has decided to provide additional life insurance and health insurance facilities for improved coverage. Speaking to The Hindu, M.S. Jayakara, Vice-Chancellor of the University, said, 'Most of our students are from economically weaker families. They are not able to afford life insurance and health insurance. Till now, compensation has been provided from the university's accumulated fund, which has become a burden. In this context, it has been decided to provide insurance facilities to all students.' Implementation The university has decided to include the insurance premium amount with the annual fees paid by students. 'I have instructed the finance officers to discuss and report on the insurance amount to be fixed for students. The insurance scheme will be implemented without burdening the students by getting assistance from the State government too,' said Dr. Jayakara. Students welcome move Students have welcomed the initiative, but requested that the insurance premium should not be a burden on them. 'Our university's decision to provide insurance facilities for the safety of students is commendable. However, students should not be burdened with the insurance premium. It would be better if the university itself pays most of the premium amount, or even makes it free of cost,' said Sinchana, a postgraduate student.

With money and manpower, India could achieve quantum satellite communication by 2030, says expert
India could be technologically capable of 'quantum communication' using satellites in the 'next half a decade' Professor Bhaskar Kanseri of the Indian Institute of Technology (IIT)-Delhi, whose team recently reported an instance of quantum key distribution one kilometre apart — the farthest such transmission in India, without any connecting cables — told The Hindu in an interview. This, however, would require large teams of well-funded multidisciplinary experts and the involvement of start-ups which are specifically geared towards such ends, Prof. Kanseri said. Safe quantum communication requires enabling a sender and receiver to get 'quantum keys', which are made of streams of photons — the carriers of light. Quantum Key Distribution (QKD) employs principles of quantum mechanics: the incompletely understood principles underlying the behaviour of atomic and sub-atomic particles, including photons. While there are a couple of approaches in using QKD, one of them — said to be the most secure but technically harder to implement — uses quantum entanglement. Pairs of photons are naturally 'entangled', in a way that a change in one instantaneously reflects in the other. Applying this to encryption means that even the mere attempt by a potential hacker into a QKD-secured transmission of information becomes apparent to those communicating, thus allowing preventive measures. While generating such secure keys can be done through physical networks, including fibre optic cables, the goal is to be able to do it in 'free-space' or without such intervening wires. This is because the cost of such transmissions using cables rapidly rises once the sender and receiver are hundreds of kilometres apart. Thus the ideal step would be to involve satellites, which can act as an intermediary between any two points even if they are thousands of kilometres apart. However, using fibre optic cables provides a stable channel for quantum communication which free-space channels do not. Atmospheric disturbances such as turbulence, air flow, pollution, etc., particularly in a city such as the Delhi National Capital Region, made it more 'challenging' to demonstrate free-space quantum communication. 'The photon beam of quantum channel diverges and wanders due to these disturbances and results in more errors. Owing to these reasons, the error rates are generally higher than the fibre ones. However, with better beam control and optimisation, there is a scope to reduce these errors,' Prof. Kanseri said. China had demonstrated satellite-based quantum communication nearly one decade ago, as they had a head start in quantum communication activities since the early 2000s, he surmised. 'I strongly believe that India, which started quite recently (in the 2020s), will achieve it in next half-a-decade or so, as under the National Quantum Mission (NQM), a strong focus is to develop satellite-based long distance quantum communication,' Prof. Kanseri, who is currently in the U.S., said in an email. As an academic institute, IIT-Delhi's experiments in quantum communication so far were 'proof of concept (POC) nature' conducted with a small team of four to five students, explained Prof Kanseri. 'Satellite based quantum communication would be one of the biggest projects and require not only adequate funds but also a large, dedicated team of multidisciplinary skilled experts for developing several types of enabling technologies. Quantum startups, mentored by researchers working in quantum technologies, if funded adequately, can contribute immensely in translation of technologies from lab to market, and in prototyping quantum technologies in a focussed and faster manner. In addition, indigenous development of needed equipment and components is also required,' Prof. Kanseri said. In 2017 and 2020, researchers at the University of Science and Technology of China, during multiple instances, generated quantum keys involving a satellite (500 km above the ground) and ground stations 1,000 and 1,700-km apart. Since 2005, there have been ground demonstrations in Europe, Canada, and the United States of free-space (without cables) QKD greater than 100 km, suggesting that India still has much to cover regarding QKD-entanglement communication. In January 27, 2022, scientists from the Department of Space (DOS), namely, Space Applications Centre (SAC) and Physical Research Laboratory (PRL), both in Ahmedabad, jointly demonstrated quantum entanglement based real time Quantum Key Distribution (QKD) over a 300-metre atmospheric channel. In 2021, a team of scientists led by Urbasi Sinha demonstrated perhaps the first instances of such free-space communication in Bangalore over building separated by 50 metres. Quantum key distributions over much greater distances have been achieved over optical fibre networks. Prof. Kanseri's team demonstrated an intercity quantum-communication link between Vindhyachal and Prayagraj in 2022, using commercial grade underground dark optical fibre. In 2024, the team successfully distributed quantum keys using entanglement over a 100 km spool of telecom-grade optical fibre in another project supported by the Defence Research and Development Organisation.
