Consider this - the WHO says that "no threshold [of small particulate concentration] has been identified below which no damage to health is observed" and so, they've instead stated a guideline that aims to achieve the lowest possible PM concentration - this is 10 micrograms per cubic metre for PM 2.5. Delhi's is 15 times that much!
Is it possible to walk in a better, more energy-efficient manner? Samanth and Padma find out the answers in this episode of The Intersection. They also explore how we ended up walking on two legs in the first place.
For the past 25 years, the Ig Nobel Prize, organised by the magazine, Annals of Improbable Research, has been honouring many seemingly silly scientific achievements.
This episode of The Intersection investigates the evolution of army food in India since the Second World War, and finds out how food research and science have come together to create a nutritious diet that takes into consideration operational logistics as well as food preferences and habits.
This episode of The Intersection brings the story of Sejal Worah, World Wildlife Foundation India's programme director, a woman who single-handedly revived the ecosystem of Mussoorie's Flag Hill. There's a lot of determination and some of childhood nostalgia (she grew up in the vicinity of Flag Hill) in her story of how she saved an entire hill. But the key takeaway is how nature can often heal itself.

Whether or not time was present before the Big Bang, it exists in our universe - we have simply invented a way to measure it, which is through seconds, hours and years. So, the question that then arises is who sets the time? This episode of The Intersection takes you to the National Physics Laboratory in New Delhi, to find out just that.
NEW DELHI -- An account of Sri Lanka's civil war by Indian author Samanth Subramanian has been longlisted for the Samuel Johnson prize 2015, making him the second Indian to be nominated for the presti...
"Only two things are infinite, the universe and the human stupidity..." - that's how a popular quote by Albert Einstein starts. He forgot about one other infinite thing: pi, which is as important as the universe and as irrational as human stupidity. This episode of The Intersection takes a look into the many different aspects of pi and explains why this number is so important.

For anyone who leads a hectic, urban life, the sheer lack of time is a common complaint. Meeting deadlines at work, everyday commuting and domestic chores often take a toll on our social lives and interests. "If only I had a few more hours in a day," is a sentiment that most of us can identify with. And some of us, who really ponder about how we can add more hours to our day, may start to wonder whether it's really worth spending a huge chunk of our day on sleep. This episode of The Intersection investigates that very idea - is it possible for us to sleep less and well?
These recurring headaches, which are usually accompanied by nausea and disturbed vision, can be debilitating and while there's no cure for them right now, a solution might just be around the corner. Samanth Subramanian and Padmaparna Gosh find out more in this episode of The Intersection.
On 15 July 2015, New Horizons, a spacecraft built by the Applied Physics Laboratory (APL) at John Hopkins University, flew past Pluto. As the New Horizons science team erupted in proud cheers, there were two other scientists who were probably feeling just as proud.
Physics works in a strange manner. In order to understand the mysteries and complexities of our vast universe, you often have to enter tiny underground holes to study matter. This is exactly what a group of scientists aim to do with the Indian-based Neutrino Observatory (INO). The observatory, first proposed in 2001, aims to study neutrinos, which are fundamental particles that we have a lot to find out about.
