Yeast could hold the key to custom-built DNA
Scientists have been playing with DNA for a long time, but now researchers are taking things a step further by building DNA from scratch in a bid to conquer life's blueprint. An international team of 11 labs from four continents are working together to "rewrite" the yeast genome, a project which could reveal the hidden rules that govern the structure of all living things. The controversial work, headed up by New York University, aims to enable scientists to create custom-made DNA codes. These could then be placed into living cells, changing how they function and giving valuable insight into disease. Much further down the line, scientists may even be able to create entirely new organisms. The right adjustments could also make yeast create new, efficient biofuels.
NASA finds biofuels make air travel 70 percent greener
Air travel releases almost 800 million tonnes of CO2 into the atmosphere, pushing us ever closer to our looming environmental catastrophe. NASA scientists want to do something about it, and teamed up with researchers in Germany and Canada to find a way to tackle the issue. Its findings claim that jets that use biofuels emit up to 70 percent less pollution and reduces the formation of water condensation trails (contrails) in their wake.
