The charity Sneha has just completed a new study which examined in detail the diets of 7000 children under the age of five living in slums or shanty towns in Mumbai. The researchers were led by David Osrin, Professor of Global Health at University College London, and found to their surprise that children not only had nutrient-poor diets but also many were eating a lot of unhealthy sugary, fried and salted snack foods.

Changing behaviour
We all know that elements of the environment affect our behaviour. But how about the bacteria, parasites and viruses that infect us? Research is starting to reveal that they might all have an impact on the way we behave.

Voice
Radio 3 is currently in the midst of a season focusing on all aspects of the Classical Voice. Science is playing a growing insightful role in understanding how to get the best out of the singing voice. Many singers base their careers on a particular quality of voice, and that sometimes can sound as though we're imposing a lot of strain on our vocal cords. We hear from Julian McGlashan, an Ear Nose and Throat specialist at Nottingham University Hospitals who has taken singers and placed a video endoscope down each of their throats to observe how their vocal tracts behave differently according to the style they sing. And David Howard head of the Audio Lab at York University, discusses how new technology is helping us understand how it's possible for a singer's voice to cut above the sound of an orchestra and still be heard at the back of a vast auditorium.

Science Hour was presented by Claudia Hammond with comments from 成人快手 Science Correspondent Rebecca Morelle.
