The leading cause of death in the world is not wars or famines but cardiovascular diseases, and worse still, we haven't fully understood what causes these ailments. Researchers believe it to be a mix of genetic factors, lifestyle changes, diet and environmental factors like air pollution, noise and our neighbourhood. In recent years, cases of high blood pressure and hypertension, which directly contribute to heart diseases, have increased, and those living in low and middle-income countries are the most vulnerable.  A recent study, published in the journal Epidemiology, aims to examine the associations between long-term exposure to ambient particulate air pollution, and prevalence of hypertension in adults from peri-urban India. 

The differences in a child’s response to visual changes could point beyond how the brain functions, how it remembers its surroundings and detects changes.

We have all heard of the Indus Valley Civilisation.It is well known for its granaries, drainage systems and systematically planned cities like Harappa and Mohenjodaro. However, not much is known about its rise and fall; although there are various theories. In a pair of new studies published in the journals Science and Cell, a consortium of international researchers, including those from India, have tried to decipher the origins of present-day Central and South Asian people. They have used recent advances in genetics to extract and analyse genetic material (DNA) from the remains of several ancient populations, including people from the Indus Valley Civilisation.

Researchers from the Indian Institute of Science (IISc), Bengaluru study how a protein called lysozyme, an integral component of our immune system, causes persistent nerve pain during nerve injury.
