Hydrogen synthesis: When enzymes assemble themselves in the test tube
Researchers have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein – a so-called hydrogenase from green algae – is made up of a protein scaffold and a cofactor. The latter is the reaction center where the substances that react with each other dock. When the researchers added various chemically synthesized substances to the protein scaffold, the cofactor spontaneously assembled.

Decentralized production of hydrogen peroxide: Using surplus renewable power
Wood-colored pulp from which white paper is to be produced, objectionable tooth discolorations or disinfecting work areas in hospitals and food production facilities: Due to its highly oxidizing and cell toxic effects hydrogen peroxide is widely used as a bleaching agent and disinfectant in many technical areas, the production of cosmetics and medical applications. Hydrogen peroxide has also become firmly established in oxidative water treatment. Here, under the influence of ultraviolet light, hydrogen peroxide forms hydroxyl radicals: these destroy organic molecules that are not easily biodegradable.

Weed stems ripe for biofuel
A weedy plant found on the roadside in northern Australia has stems ripe for biofuel production. Scientists have discovered that a variety of sorghum growing wild in Australia, Arun, has the potential to yield over 10,000 litres of bioethanol per hectare per year.

Heme, a poisonous nutrient, tracked by 'Green Lantern' sensor
(Georgia Institute of Technology) The toxin heme is essential to life, but cells must make use of it sparingly and carefully, as poor heme management can lead to Alzheimer's, heart disease and cancer. Researchers at the Georgia Institute of Technology tailored ratiometric sensors to tracks heme's movements in yeast cells for the first known time.

'Dirty Blizzard' sent 2010 Gulf oil spill pollution to seafloor
(The Earth Institute at Columbia University) Scientists working in the Gulf of Mexico have found that contaminants from the 2010 Deepwater Horizon oil spill lingered in the subsurface water for months after oil on the surface had been swept up or dispersed. In a new study, they detailed how remnants of the oil, black carbon from burning oil slicks and contaminants from drilling mud combined with microscopic algae and other marine debris to descend in a 'dirty blizzard' to the seafloor.

Wind turbines on Galapagos replace millions of liters of diesel since 2007, meet 30 percent of energy needs
(Terry Collins Assoc) A trio of wind turbines operating on the Galapagos Islands since 2007 has mitigated the need for diesel imports and inspired an ambitious plan to expand renewable energy in this ecologically precious archipelago with a growing appetite for electricity.The performance summary and expansion recommendations are contained in a report by the Global Sustainable Electricity Partnership, which led and financed the initial $10 million wind project.
