Balancing Biofuels in African Agriculture

02 July 2010
Presented by Chris Smith.

This week, we look at ways to balance the demand for biofuels against the other needs of African farmers. We find out why size matters when it comes to bird beaks, how plant roots cope with competition and what astronomers can learn about neutrinos. We hear from researchers who are building new lungs in the lab, and in question of the week we ask why the right side of the brain controls the left side of the body!
