Science brings us many wonderful things (honestly if you enjoy the benefits of the modern era, go out and hug a scientist). One of humanities age old desires is the ability to convert something invaluable, or a nuisance, into something desirable. The old midas touch if you will. Recently some scientist stumbled onto the process of converting CO2, a primary culprit of anthropogenic climate change, into alcohol… though not the kind you drink, the kind that humanity could use as fuel.

Producing fuel from CO2 is huge because it lets us take a nuisance compound, and converts it into a productive one. This was accomplished by scientists at Oak Ridge National Laboratory in Tennessee by using common materials (copper and carbon), but arranging them with nanotechnology. The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, such as ethanol. They figured they would go from CO2 to methanol, and then work out the logistics of going from methanol to ethanol, when they realized the first step in their process managed to do it all by itself. Science for the win!

Conservation has long had the concept of Flagship Species—popular, charismatic species that serve as rallying points for conservation awareness and action. Formalized within the framework of conservation marketing, flagship species are focused around particular goals and audiences. Think of the WWF’s Giant Panda, Polar Bears and a thousand different arctic or climate change campaigns, or even the American Bald Eagle, whose decline galvanized the country into action. These animals are iconic. They connect people to species and ecosystems in crisis. They are Flagship Species.
The Giant Deep-sea Isopod is not a flagship species. The Giant Deep-sea Isopod addresses a much more fundamental issue: despite being the largest, most diverse ecosystem on the planet, most people have no direct connection, no frame of reference, for the deep sea. (more…)

Dr. Bernie Kuhajda joined the Tennessee Aquarium Conservation Institute staff in May 2012 after 25 years at the University of Alabama, where he managed a museum collection of one million specimens of preserved fishes from all around the world. Though his studies of fishes and other aquatic organisms have taken him around the United States, Mexico, and Central Asia, his particular expertise is surveying and monitoring threatened and endangered species from aquatic systems in the Southeast, in part to help evaluate the effectiveness of conservation programs. He currently teaches weekend courses at the University of Alabama Gadsden Campus and on the main campus in Tuscaloosa every summer. He serves on multiple USFWS Recovery Teams/Groups for endangered and threatened species.
Imagine possessing untold wealth but lacking the means to keep it safe. That is the broad-strokes reality faced by those of us who work to protect the Southeast’s rich aquatic biodiversity.
Our waterways are home to an incredible natural profusion, one that is unrivaled in the temperate world. More than 1,400 aquatic species reside in waterways within a 500-mile radius of the Tennessee Aquarium’s home in Chattanooga, including about three-quarters (73.1 percent) of all native fish species in the United States. More than 90 percent of all American mussels and crayfish species live within that same area, as do 80 percent of North America’s salamander species and half of its turtle species.
