The US-China power balance

Talks between US President Barack Obama and Chinese
President Hu Jintao are being billed as the most important meeting between the
two countries for 30 years. It comes at a time when relations have been strained
by issues such as the trade imbalance and China's growing military might.

On the map

Until recently, what is often billed as one of Africa's largest slums
- Kibera, in the Kenyan capital Nairobi - was a blank spot on official maps. But
a group of volunteers have been training young people living there to create
their own digital map of the area.



The result is the first complete map of Kibera, which it is hoped can form
the basis of plans to improve the area and the lives of its residents
