Working in different shifts disrupts the body’s circadian rhythm—a natural process in our body that regulates the sleep-wake cycle.

Researchers at the Indian Institutes of Technology at Kharagpur and Kanpur, and also from Princeton University, USA, have designed a model, based on social networks of voters, to make reliable predictions on the ‘surprise’ element of election results and suggest possibilities of decreasing it.

A recent study by an international group of researchers has revealed some unpleasant reality of a government-aided program in Bihar for diagnosing leprosy and has estimated the efficiency of an approach that can promote accurate diagnosis of the disease.

In a series of articles, Research Matters tries to explain the commonly accepted process of scientific methodology, the interpretation of scientific studies and the obvious pitfalls. It is hoped that this series will help lay public in analysing any understanding published scientific studies for what they are, instead of believing just because ‘scientists say so’. This article is the first in the series.

Every year, the 5th of June is observed as the World Environment Day to “encourage worldwide awareness and action to protect our environment”. For 2019, the theme is ‘Air Pollution’, and the host country is China. On this occasion, Research Matters caught up with three leading scientists from the country that are actively pursuing research on different aspects of air pollution. The three researchers, Prof. A R Ravishankara, Prof. S K Satheesh and Prof. Navakanta Bhat shared their work and thoughts on the ‘burning’ problem of air pollution.

Researchers at the Karnataka Health Promotion Trust, Bengaluru, have assessed the cost effectiveness of a self-help group program, called Parivartan, in Bihar. They studied the economics of implementing maternal health programs through self-help groups.

Researchers from IISc, Bengaluru, have designed a smartphone-based therapy and hearing aid.

The extensive use of fireworks, particularly during festivals like Diwali, releases large amounts of harmful gases and toxic substances into the atmosphere. As a result, the air gets polluted and can affect our health. In a recent study, researchers from the Indian Institute of Technology Guwahati and the Indian Institute of Technology Delhi have analysed the excessive air and noise pollution caused by firecrackers during Diwali and their potential impact on health.

A multi-national team of scientists spanning Asia, Europe, South America and Australasia, including researchers from the Indian Institute of Technology Delhi, have surveyed nearly 17,000 people across 39 countries to understand why interpersonal relationships differ between societies.

Melting glaciers, rising sea levels and the threat to biodiversity are some of the conspicuous impacts of global warming. However, the repercussions of this warming are multifaceted and complex than what we understand today.
