(Press-News.org) In Punjab, India, paddy stubble burning is a widespread agricultural practice that contributes to seasonal air pollution in the region and beyond. However, the extent to which residents recognize its impact on their own environment and health or in the highly populated areas of Delhi National Capital Region (NCR) has remained unclear. To address this gap, the Aakash Project (led by researchers from Hokkaido University in collaboration with Indian research partners) conducted interviews with 2,202 households across 22 districts in Punjab.
Urban air pollution is recognized, but local sources are undervalued
About 46% of respondents perceived air pollution in Delhi as “severe,” while only 25% viewed air pollution in their own areas of Punjab as severe.
Personal health experience increases awareness
Households with family members experiencing respiratory or cardiovascular problems were more likely to recognize smoke from stubble burning as harmful and to view the practice as a pressing issue requiring action.
The study reveals a perception gap: while urban air pollution is widely acknowledged, the contribution of locally generated smoke from stubble burning remains less recognized. Personal or familial health experiences and health literacy play a crucial role in shaping awareness. These insights suggest that efforts to reduce stubble burning and improve air quality must include clear, locally grounded communication on health impacts, supported by accessible and visible air quality information.
*The Aakash project is exploring ways to shift people's behaviour to sustainable agriculture in the Punjab region to reduce the health hazards caused by air pollution, by clarifying observation-based relationship between straw burning and local air pollution; raising awareness of the importance of maintaining clean air among residents; and proposing the effective and beneficial use of rice straw by farmers.

How fast you can walk before hip surgery may determine how well you recover
2025-12-01
Fukuoka, Japan—Total hip arthroplasty (hip replacement) is a common treatment for hip osteoarthritis, a degenerative joint disease caused by cartilage in the hip joint wearing down. However, clinical outcomes vary between patients, and the best timing for surgery remains unclear.
Now, researchers at Kyushu University have identified that pre-surgery walking speed is a strong predictor of post-surgery outcomes. In a study published on 26 November in The Journal of Bone and Joint Surgery, they found that patients ...
Roadmap for reducing, reusing, and recycling in space
2025-12-01
Every time a rocket is launched, tons of valuable materials are lost, and huge amounts of greenhouse gases and ozone-depleting chemicals are released into the atmosphere. Publishing December 1 in the Cell Press journal Chem Circularity, sustainability and space scientists discuss how the principles of reducing, reusing, and recycling could be applied to satellites and spacecraft—from design and manufacturing to in-orbit repair and end-of-life repurposing.

Long-term HIV control: Could this combination therapy be the key?
2025-12-01
A new study from UC San Francisco shows it may be possible to control HIV without long-term antiviral treatment — an advance that points the way toward a possible cure for a disease that affects 40 million people around the world.
Treatment with a combination of experimental immunotherapy agents enabled seven out of 10 participants to keep the virus at low levels for many months after going off antiretroviral therapy (ART).
The results appear on Dec. 1, World AIDS Day, in Nature.
The trial, which relied on a collaboration with ...
Home hospital care demonstrates success in rural communities
2025-12-01
One in five people in the United States live in a rural area. Patients in rural communities often struggle to access care because of travel difficulties, high costs and limited resources, leading to worse medical outcomes. With over 150 rural hospital closures since 2010, innovative approaches to care delivery in rural areas are needed. In a new study by investigators from Mass General Brigham and Ariadne Labs, in collaboration with colleagues at rural U.S. and Canadian health centers, researchers found that hospital-level care at home is feasible for patients living in rural areas with acute conditions ...
Hospital-level care at home for adults living in rural settings
2025-12-01
About The Study: In this randomized clinical trial of home hospital care in rural settings, cost and readmission were unchanged while patient activity and experience improved. Late transfer home likely attenuated the intervention’s effect.

Health care access outcomes for immigrant children and state insurance policy
2025-12-01
About The Study: In this cross-sectional study of U.S. children, immigrant compared with U.S.-born children had disparities in health care access, which were attenuated in states with the most inclusive state insurance policies, suggesting that inclusive state insurance eligibility policies for immigrant children may improve health care access outcomes for this population.

Change in weight status from childhood to young adulthood and risk of adult coronary heart disease
2025-12-01
About The Study: This study found that individuals with overweight in childhood who had normal weight in young adulthood had similar risk of coronary heart disease as individuals with normal weight in childhood and young adulthood. These findings have implications for public health planning, emphasizing the importance of early detection and treatment of overweight during childhood and adolescence.

Researchers discover latent antimicrobial resistance across the world
2025-12-01
A team of researchers has discovered that latent antimicrobial resistance is more widespread across the world than known resistance. They call for broader surveillance of resistance in wastewater, as the problematic genes of the future may be hiding in the widespread reservoir of latent resistance genes. The research has been published in Nature Communications.
A group of researchers has analysed 1,240 wastewater samples from 351 cities in 111 different countries and found that bacterial latent antimicrobial resistance is widespread on all the world’s continents. The research was coordinated by the DTU National Food Institute ...
