Researchers show how free-ranging dogs modify their behaviour and personalities based on our presence in urban areas.

COVID-19, the pandemic that has shaken the world, will perhaps change our lives forever. Often, we now talk of a ‘pre-COVID’ world, where business was as usual, and a ‘post-COVID’ world which is the new normal. While the disease, caused by a tiny virus, has affected millions, it has also brought to fore some often-ignored challenges and opportunities to build a better tomorrow. Science has been in the forefront, driving these monumental changes across the world—from understanding the virus and designing a vaccine, to throwing insights on how we could prepare for and prevent the next pandemic.

In a recent study, researchers have proved that when we talk to our loved ones, the variations in our speech are independent of language and culture. It also shows that a lack of such variety in our talk can result in problems with social communication. 

A recent study by a team of researchers gives some insights into diagnosing bladder cancer early enough and preventing misinterpretation.

Tuberculosis, caused by the bacteria Mycobacterium tuberculosis, is a leading cause of death worldwide. In 2017 alone, 10 million people across the globe were affected by the disease, and about 1.6 million succumbed to it.

Obesity has become a global concern over the last four decades as the number of obese and overweight individuals has tripled since 1975. In 2016, about one in five children across the world, aged 5-19 years, were overweight or obese and half of them lived in Asia. The obesity epidemic, which was once prevalent in high-income, developed countries, has today soared in low- and middle-income economies, particularly in cities. A similar trend is observed in the case of hypertension—a major risk of obesity. In India, many studies have assessed the prevalence of obesity and hypertension and the correlation between them. However, recent data on this, particularly regarding children and adolescents from urban and rural areas, is scarcely available. Now, a recent study by researchers from India and the UK, published in the journal BMJ Open, provides some insights into the current prevalence rates for obesity and hypertension among adolescents in Northern India.

India is ageing. Approximately 104 million Indians are above sixty and vulnerable to cognitive disorders affecting memory, such as dementia. Despite this impending future, we haven't been able to assess the current prevalence of such illnesses in the country. It is partly due to the geographical and cultural vastness of India, and the barriers of language and ethics prohibit the use of tests used in western countries. Now, a new study is trying to close this gap by introducing a psychological test that is adapted to the cultural and linguistic diversity of India.

Building on their previous research, researchers at Tata Memorial Centre (TMC), Mumbai have tried to find out the root cause of sepsis in a recent study. So far, most drugs treat the symptoms of sepsis, such as inflammation, rather than its causes. In this study, the researchers find that broken pieces of chromosomes could trigger sepsis. The results of the study are published in the journal PLoS ONE.

 A recent study explores how childhood vaccination among children in India has impacted the level of education attained by them as adults.
