US research has found that the popular herb, coriander, has a high affinity to heavy metals. In simple terms, coriander can bind to metals such as nickel and lead which are highly toxic, making water safer to drink.
Although this method could not be used on a large scale, this knowledge could help those, in parts of the world where coriander is readily available, to drink safer water. The research was carried out at Ivy Tech Community College and has shown that up to 20mg/g of nickel can be removed from solution in 45 minutes and 145mg/g of lead in just 15!
Although the exact mechanism of how this process works is not understood, this discovery means that some form of 'teabag' could be produced on a large scale, helping even more people worldwide. I am definitely going to keep my eye on this story and keep you updated!

Water of life!
One of the main reasons for bad health in third world countries is the lack of freshwater, making the need to purify water increasingly important.
Scientists from South Korea have been working on a method called capacitive deionisation to tackle this problem by desalinating water on a large scale. Capacitive deionisation uses an electric field as a sort of magnet to draw out the anions and cations present in water. You may be familiar with this method on a small scale, using electrodes. Capacitive deionisation is effectively the same method but on a much larger scale - scaling it up by increasing the flow of electrons in the system.
This idea holds great potential and although very simple I think it will be a breakthrough in tackling bad health in undeveloped countries, which really is great.
