We’re used to images of near-apocalyptic pollution in Beijing.
But the world’s worst air can be found some 2,400 miles to the west.
The World Health Organization labeled New Delhi, India as having the dirtiest air out of 1,600 cities around the world.
Tiny particles of pollution go deep into the lungs and are more likely to cause chronic health problems.
According to analysts, New Delhi’s pollution levels are mainly the result of the large number of old vehicles on roads, the burning of bio-mass, industry emissions and coal-powered power stations.
A breath test may be able to indicate whether someone may be at high risk for stomach cancer.

Researchers surveyed nearly 14,000 adults and about four percent said they often have nightmares.

Researchers believe this study will help them determine if someone has the early onset of depression.
