A young scientist who worked in the jungles of Thailand has been awarded a national prize for his invention of a $2 paper microscope that can be taken on field expeditions.

If a scientist wants to study something at the microscopic level, they need a microscope, which if they are deep in the Amazon Rainforest presents a serious problem.

Stanford University bioengineer Manu Prakash saw in his team's $50,000 microscope a serious contradiction. As well as being bulky and ridiculously challenging to transport to remote locations, it needed training from skilled technicians to know how to use it. It also had to stay well out of the weather and other environmental impacts.
