Many marine organisms have a planktonic form. This means that they drift in the ocean for part of their life until they can find something suitable to attach to and grow. A common example of an animal like this would be a mussel or a barnacle. However, it’s a real headache when they land on human-made structures that…

Do you love tuna sushi? Did you know that the number of tuna in the ocean has gone down drastically due to overfishing? The law of supply and demand tells us that as the availability of fish decreases, the price will go up. This is bad news for fish and the humans who eat them. Researchers in Japan want to make sure…

Although bacteria are unicellular and may be freely swimming in water or crawling on sediments, in many environments they live in clumps called biofilms. Biofilms are groups of bacteria that grow on a surface and huddle together by sticky carbohydrates that they produce. Similar to how emperor penguins pack tightly to…

Researchers in Germany and Switzerland used next generation sequencing to study an active aquaponics system. They sampled a biofilm from the side of the tank, the fish excrement, the plant roots, and the inside of the tank filter, called a biofilter.

Cars are everywhere. They are essential for our day to day lives, but these vehicles are a double-edged-sword. Cars emit exhaust gases, and those gases contain hydrocarbons. These molecules, as their name suggests, contain both carbon and hydrogen atoms. Hydrocarbons from cars result from gas that has not been…
