Widespread use of the oral vaccine has brought the eradication of polio tantalisingly within reach.

And this, a city ornithologist says, can be dangerous...

-The Business Standard Still waiting for a crackdown on antibiotic over-prescription According to a recent study in the Lancet infectious diseases journal, the drug-resistant bacterial strain known as New Delhi metallo-beta-lactamase 1, or NDM-1, has spread to 40 countries. This is quite remarkable, given that it was only discovered in 2008 in the UK, among patients who had recently been hospitalised in India. The “superbug”, as it is commonly known, is...
