A new study projects that between 2017-2030, India may witness a whopping 6.8 million deficit in the females born, by 2030.
Incidents of snakebites and resulting deaths are no rarity in India, which accounts for half the world’s deaths due to snakebites. Now, a new study claims that India has witnessed an estimated 1.2 million deaths due to snakebites between 2001-2020.
A recent study suggests that tailoring the Ujjwala scheme for rural households can increase LPG adoption.
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.
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.
A curious question in science is to know how these different types of lions evolved and how different are today’s lions from their ancestors. In a new study, an international team of researchers have tried to answer these questions by analysing the genes of extinct and living lions. The study, published in the Proceedings of the National Academy of Sciences (PNAS), finds that about 500,000 years ago, modern and now-extinct lions shared a common ancestor. Further, about 70,000 years ago, two different lineages of modern lions emerged. The findings also have implications on the conservation of the remaining lion population, which is just 10% of what it was a century ago.
