Each year, the cost of health care pushes some 39 million people back into poverty, according to a study published in the Lancet medical journal. Patients shoulder up to 80 percent of India's medical costs. Their share averages about $66 (3,000 rupees) annually per person - a crippling sum for the 800 million or so Indians living on less than $2 a day.

The Dalai Lama said Saturday that India should be seriously concerned about the melting of glaciers in the Tibetan plateau as millions of Indians use water that comes from there.

A new study from Forrester proves that the majority of Americans are a bunch of lazy re-tweeters. Ninety-three percent of online consumers in emerging markets of China, India, Mexico and Brazil use social media tools at least once-a-month. U.S. and European consumers are far more likely to use social media as a spectator-like sport, joining it and then just watching it fly by. In the U.S., 68% of social media users are joiners, which means they maintain a profile on a social networking site and visit social networks. Only 73% are spectators, or users who mostly just read blogs, online forums, customer ratings/reviews and tweets, listen to podcasts and watch videos. This number is strikingly similar in Europe (EU-7 countries, to be specific), with 69% of users classified as spectators and 50% as joiners.

If internal and international migrants comprised a nation, it would be the third most populous country in the world, just after China and India. Thus, there can be little doubt that population mobility is among the leading policy issues of the 21st century. However, policies to protect migrants and global health have so far been hampered by inadequate policy attention and poor international coordination. This is the conclusion of a new article in PLoS Medicine arguing that current policy-making on migration and health has been conducted within sector silos, which frequently have different goals. Yet, population mobility is wholly compatible with health-promoting strategies for migrants if decision-makers coordinate across borders and policy sectors, say the authors, who are also serving as guest editors of a new series in PLoS Medicine on migration & health that launches this week.

In a country where nearly 40 percent of households have no electricity, any new advancement that will help bring power to the world's second most populous nation, must be met with celebration and open arms.

We're stumbling through a science fiction wonderland of not just high-flying communications software and tools but of the basic building blocks for the devices we use to do that communicating. The latest contender for radically-improved memory in a computer? Blood. Researchers in Gujarat, India have created a "memristor" -- a portmanteau of memory and resistor -- made of human blood. A resistor is the part of a computer chip that regulates the flow of electricity. Unlike most resistors, a memristor remembers previous levels of voltage and allows for a repeat of that flow.

India's tiger population has increased for the first time in decades, a newspaper said on Saturday, citing a national tiger census report slated to be released next week.

More than one billion urban residents will face serious water shortages by 2050 as climate change worsens effects of urbanization, with Indian cities among the worst hit, a study said Monday.
