Sophia Dower In May this year, a major brewery in southern Africa was the first to test the abilities of a new biofilm monitoring and treatment system - one that looks set to save industrial water users hundreds of thousands of rands in production and running costs.
Wagdy Sawahel Turkish scientists have discovered a plant that can remove boron from soils. They say that it could provide a low-cost way of 'cleaning up' soil contaminated with this naturally occurring trace element that is toxic to most crops at high concentrations.
Pioneering auto maker Henry Ford was a man before his time. In the 1940s, his vision to "grow automobiles from the soil" resulted in an experimental car made of resin-stiffened hemp fibre, more resistant to denting than steel. More than half a century later, an industry partnership between the Ford Motor Company and the University of Toronto's Dr. Mohini Sain and his collaborators are resurrecting Ford's dream. The chemical engineer is developing technology that will replace the sheet metal and glass fibre used to build cars with natural fibre composite materials, such as hemp.
THE EAST African countries of Kenya, Ethiopia, Uganda and Tanzania are cementing their countries support for biotechnology by developing laws that will give them a chance “to maximize benefits from modern biotechnology”.

If current predictions hold true, fuel cells are likely to penetrate everywhere where energy is used from laptops to vehicles, from home to business. But what exactly is a fuel cell, how does it work and why are billions being poured into this research?
