Bacterial in human body is more than often viewed as the cause for infection and disease. It is hard to think it as beneficial if it is not harmful. However, researchers from the University of Delaware and Cornell University have made a progress in engineering bacterial to treat diabetics. The bacterial is engineered to produce a protein called GLP-1 which is showed to help the diabetic mice having normal glucose blood levels. Growing bacterial is much cheaper than synthesizing the artificial insulin. In addition, if they can live healthily in human body, then the patient does not have to take the treatment once after a while. Biotechnology would greatly expand our current method of treating disease in the future.

Novel bacterial strains clear algal toxins from drinking water
http://www.eurekalert.org/pub_releases/2009-09/sfgm-nbs090209.php
The researchers in Britain have identified six strains of bacterial that is able to remove toxins produced by blue green algae from water. The blooms of Blue green algae are widely found in water especially in the nutrient rich water body usually polluted by human activity. They produce toxins that are poison for fish and human. Traditional method to clean up the water is not only costly but also introducing other chemicals that may cause other potential problem. Using bacterial as a part of nature to solve the environmental problems may indicate that in the future, we may be able to solve most of the environmental problems by find out its natural “predator” and redirecting it to its balance.

Colorful Solar Panels, the new trend for future housing design.

A company named GreenSun reports its new intention of the colorful solar panels. Unlike the current solar panel which is dumbly gray color, the new solar panels are given vibrant colorful appearance. Moreover, it does not require the direct sunlight shining on it but could still hold its energy efficiency according to the company. That is to say the new material could be used not only on the top of the roof where no body would give it an attention. Instead, these colorful solar panels could be installed on side wall for example, as well. Undoubtedly, this new technology will be a powerful element that architecture has to explore for its colorfulness and its environmental friendliness.
