Saving Sushi: Groundbreaking Progress in Bluefin Tuna Farming Controlled fertilization of bluefin tuna eggs opens the door to many potential improvements through selective breeding.

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 READ MORE

New Study Elaborates on What Aquarium Owners Already Know Aquarium owners know that the right bacteria are critical for a healthy fish tank. But which bacteria are the right ones?

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.

How Do Algae Biofuels Compare to Diesel in Real Engines? Scientists put algae biodiesel blends and plain diesel fuel to the test in real engines to compare their efficiency and emissions.

Choosing the right species of algae is one of the most important first steps, they report, as it ultimately impacts the engine’s performance and amount of exhaust emissions.

The Latest Cutting-Edge Water Filtration Technique Was Inspired By Your Kidneys Both scientists and start-ups are excited about using water-filtering proteins called aquaporins to make seawater drinkable.

The latest cutting-edge water filtration technique comes from a biochemistry process that predates even dinosaurs. It involves harnessing aquaporins, a protein in cell membranes which are present in all living things.

Is Organic Farming Really Better? It Depends. Organic farming and conventional farming each have their own strengths and weaknesses that depend on application.

Bacteria-Powered Battery Helps Remove Lake Pollution Combining aquatic plants with a microbial fuel cell effectively reduces nitrogen pollution in water

Nitrogen pollution is a big problem in standing water such as lakes and ponds. The nitrogen comes from many sources, often agricultural fertilizers. Some of this nitrogen is in the water, but the rest of it is actually trapped in READ MORE

Growing Plants with Colored Light Changes Their Nutrient Content Apparently, when you stress plants out by removing green light, they pump out more antioxidants!

Plants have five basic needs – food, water, air, light, and space. Outdoors, plants get everything they need from nature and some human intervention. However, when growing plants indoors, these five basic needs have to be provided artificially. Why would READ MORE

Grow High-Tunnel Lettuce Year Round on Fish Waste Flow-through aquaponics may help improve winter lettuce yields for farms using high tunnels, giving fish poop a whole new purpose.

A group of agricultural researchers at West Virginia University wanted to find out if it was possible to grow lettuce year round using high tunnel aquaponics instead of traditional greenhouse methods. Aquaponics is a term that combines “aquaculture,” the practice READ MORE

Can cold-loving bacteria help to clean up oil spills? The enzyme that breaks apart a major component of oil might be less active in the cold...

For several decades scientists have been interested in the ability of psychrophilic (cold- loving) microbial communities to degrade the various components of crude oil, which is a process known as bioremediation. Because temperature has a direct impact on enzyme activity READ MORE

How Long Will Human Civilization Last? Combining fields of sustainability and astrobiology to probe human civilization longevity

Human-caused climate change, ocean acidification and species extinctions may eventually threaten the collapse of civilization, according to some scientists, while other people argue that for political or economic reasons we should allow industrial development to continue without restrictions. In a READ MORE
