3D chocolate printer
Hardware of a very different stripe made our silicon.com photo stories with the news that the University of Exeter has created a machine that can print 3D objects - like the one above - in chocolate.
The University's research team initially found chocolate a difficult medium to work with as it requires precise heating and cooling cycles that had to be integrated with flow rates for the 3D printing process. However, they successfully developed a temperature control system that enables chocolate to be printed by the machine.
To find out how it works, see Come in Willy Wonka, your time is up - meet the printer that prints in chocolate.

University of Leeds robot worm
The University of Leeds, meanwhile, revealed its latest creation - a super-sized worm robot based on the C elegans nematode worm.
The worm bot is the result of engineering fellow Dr Jordan Boyle's research into how the nervous system of the worm works to propel the creature along. Boyle envisages a developed version of his worm bot one day being used to locate and help victims of natural disasters.
To learn what makes the worm bot different from other snake-like robots and how it could potentially be used in medicine, check out Giant robot worm to the rescue.

Chikanta village chief
Further afield, July saw silicon.com catching up with the progress of Computer Aid's Zubabox internet cafés.
Computer Aid International has delivered three of these solar-powered cyber cafés housed in old shipping containers so far and is now appealing for organisations to sponsor 10 more to go to other rural communities in sub-Saharan Africa and to be used in disaster zones.
Pictured above is the ZubaBox cyber café recently delivered to the village of Chikanta in Zambia.
To learn more about the ZubaBoxes, see The solar-powered internet cafés connecting rural Africa.
