Scientist Emily Cole has created technology that can recycle carbon dioxide into something useful. She has developed a method that would turn the greenhouse gas emissions into a chemical that could be used to make consumer products like plastic bottles. Talk about innovative! Learn more here.
The sea lamprey is a parasitic fresh water fish that is invasive in the Great Lakes (why it is called a sea lamprey is a different story for another time...). Since the sea lamprey invaded in 1919, they have killed SEVERAL MILLION pounds of native fish annually. Currently managers are using chemicals to kill lamprey larvae in streams, but these same chemicals can also accidentally kill other fish, like endangered juvenile sturgeons. Researchers have developed a new control method which uses phermones (natural chemicals) produced by lampreys, to trick lampreys into migrating towards areas where they can be easily removed. If successful in the Great Lakes, this new method can be used worldwide to provide an environmentally-friendly way to control invasive species.

Large container ships come through Charleston Harbor to deliver goods from all over the world. Charleston Harbor has a whole lot of sediment in it though! Do you think the harbor is normally deep enough for large ships to sail through? It's not! The harbor is regularly dredged (digging up sediment) to pave a way for these ships to travel. As the harbor gets dredged deeper and deeper, there's been discussion of what to do with all of that sediment! Check out the article here.
