Study to explore impact of indoor air pollution on heart failure patients
The research is part of the Indo-US collaborative agreement on environmental and occupational health and focuses on one key question: Can reducing indoor air pollution improve the health of people with heart failure?
The study is being carried out at three major medical centres in India: All India Institute of Medical Sciences (AIIMS), New Delhi; Dayanand Medical College (DMC), Ludhiana; and SCTIMST, Trivandrum.
As part of the study, air purifiers were installed in the homes of 10 heart failure patients in Trivandrum and Kollam districts. The plan is to expand this number and install a total of 200 air purifiers in patients' homes across these districts.
"Air pollution is often seen as a problem of cities and traffic, but indoor air pollution is equally dangerous, especially in places where people spend most of their time — their homes.
For patients with heart failure, who are particularly vulnerable to environmental stressors, breathing cleaner air could significantly reduce complications, hospitalisations, and even death," Dr Harikrishnan S, the principal investigator, said.
He said if successful, it could lead to new guidelines for managing heart failure, emphasising the importance of air quality at home. It may also inform national health policies, making air purifiers a potential part of patient care for high-risk groups.
The findings could benefit millions of people living in polluted regions, not just in India, but globally.
With heart disease being the leading cause of death in India, innovative, evidence-based interventions are urgently needed. By focusing on the connection between clean air and cardiac health, this research places India at the forefront of an emerging area of public health. SCTIMST and its partners are hopeful that the study will provide valuable data to shape the future of care for heart failure patients — one breath at a time, Dr Harikrishnan added.

Spacetech startup Dhruva Space to launch maiden commercial mission with Australian collaboration
Academy Empower your mind, elevate your skills Hyderabad-based spacetech startup Dhruva Space is set to launch its first commercial mission, LEAP-1, in collaboration with Australian partners Akula Tech and Esper Satellites. The mission is scheduled to lift off aboard a SpaceX Falcon 9 rocket in the third quarter of startup on Monday said the LEAP-1 mission will carry two payloads on Dhruva's indigenously developed P-30 satellite platform, an artificial intelligence (AI)-powered module from Akula Tech and a hyperspectral imager from Esper Satellites. The mission represents a growing Indo-Australian strategic partnership in the space tech two payloads will have a wide range of applications across defence, disaster response, agriculture, mining, and environmental management. Akula Tech's on-board AI module is designed to process and retrain machine learning models in orbit for earth observation use cases. Esper Satellites' imager will deliver spectrally-rich remote sensing data through its will be Dhruva's first hosted payload mission after successfully testing its P-30 satellite bus in orbit during ISRO 's PSLV-C58 POEM-3 mission in January 2024. 'Dhruva Space's hosted payload offering integrates ground station-as-a-service (GSaaS) and its proprietary Integrated Space Operations and Command Suite (ISOCS) for real-time mission management and payload data downlinking,' the startup said in a startup said it is seeing a growing interest in its payload offerings from customers across India, Europe, and Australia.'Teaming up with our commercial partners in Australia creates remarkable opportunities for Indo-Australian Space business, which will, in turn, foster a long-term partnership. India is already a key economic and regional partner, and we see this mission symbolic of India's status as a fast-growing space programme,' said Sanjay Nekkanti, cofounder, Dhruva space startup credited ISRO and the Australian Space Agency, whose engagement in September 2022 led to meaningful interactions with a delegation of Australian space startups. These discussions helped build long-term Indo-Australian partnerships and support from SpaceX for mission readiness.

Here's Why Disease-Causing Bacteria Sent To International Space Station
SpaceX launched its Crew-11 mission to the International Space Station (ISS) on August 1, carrying four astronauts and an experiment with disease-causing bacteria. The scientists at the Sheba Medical Center in Israel collaborated with US-based space tech company SpaceTango to develop a study that aims to examine how microgravity affects the growth of bacterial species. The groundbreaking experiment includes E. coli, Salmonella bongori, and Salmonella typhimurium to study how microgravity affects bacterial growth and gene expression. Scientists will study how space conditions impact bacterial behaviour, including antibiotic resistance and virulence, to better protect astronauts' health on long-duration missions. "We know that space conditions affect bacterial behaviour, including how they grow, express genes, and acquire traits like antibiotic resistance or virulence," Prof Ohad Gal-Mor, Head of the Infectious Diseases Research Laboratory at Sheba Medical Center, said in a statement. "This experiment will allow us, for the first time, to systematically and molecularly map how the genetic expression profile of several pathogenic bacteria changes in space." The fact that bacteria behave differently in space is well-documented. They often grow faster and display altered characteristics. The bacteria might harm astronauts, especially during long-duration missions, as they are more prone to infections, because of a combination of microgravity, radiation, stress and changes in the human microbiome. Hence, microbiology and immunology become vital components of modern and future space medicine. Professor Gal-Mor said that the fresh insights will help our understanding of infectious disease risks in space travel, and also expand our knowledge of gene regulation and bacterial physiology in general. The statement mentioned that the bacteria will be stabilised, frozen at -80 degrees C and returned to Earth after growth under microgravity. The molecular and transcriptional analysis and direct comparison to bacteria grown simultaneously in an identical lab setup on Earth.

Groundwater dominates Ganga's flow in plains, not glacier melts: IIT Roorkee study
New Delhi: The river Ganga is primarily sustained by groundwater discharge, not glacial melt as widely believed, according to a study led by researchers at the Indian Institute of Technology (IIT) Roorkee. The study showed that natural underground contribution boosts the river's volume by nearly 120 per cent along the middle stretch. Meanwhile, more than 58 per cent of the river's water is lost to evaporation during summer -- an alarming yet overlooked component of the river's water budget. Published in the journal Hydrological Processes, the study reveals the negligible role of glacial melt in maintaining the Ganga's flow in the Indo-Gangetic plains during summer. The study quantifies that beyond the Himalayan foothills, the glacier-fed input is virtually absent and does not influence the summer discharge up to Patna. Post-Patna, tributaries like Ghaghara and Gandak become the dominant contributors. 'This research redefines how we can understand the Ganga's summer flow. It should prove a sustainable future river rejuvenation strategy, not just for the Ganga but for all major Indian rivers,' said Prof. K.K. Pant, Director of IIT Roorkee. Contrary to prior satellite-based studies warning of severe groundwater depletion across North India, the new findings based on a full-scale isotopic analysis of the Ganga River from its Himalayan origin to its deltaic end, including its major tributaries, indicate largely stable groundwater levels across the central Ganga Plain. In fact, consistent flows from shallow hand pumps across decades reinforce the evidence of a resilient aquifer system that continues to feed the Ganga during non-monsoon periods. 'Our analysis shows that the Ganga is not drying because groundwater is depleting, but due to over-extraction, excessive diversion, and neglect of tributaries. Groundwater is still the hidden lifeline of the Ganga,' said lead author Prof. Abhayanand Singh Maurya, faculty at the Department of Earth Sciences, IIT Roorkee. The findings strongly support reviving tributaries, increasing environmental flow releases from barrages, and protecting local water bodies to recharge aquifers.
