Editor's note

The International Criminal Court’s appeals chamber has acquitted Jean-Pierre Bemba two years after it sentenced him to 18 years’ for his role, as military commander, for atrocities committed in Central African Republic (CAR). The 2016 judgment was seen as an important step towards the “more just world” the ICC pursues. Kerstin Carlson explains the significance of the acquittal.

Over a million children die every year from diseases that can be prevented by vaccines. The reason for this is that vaccines need to be kept cold to remain effective. But a shortage of power supplies makes this difficult if not impossible in many places in the world, hampering mass vaccination campaigns. Jackson Thomas, Gregory Peterson, Mark Naunton, Sam Kosari and Yap Boum set out how this gap can be narrowed.
