Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; substances that contribute to increasing climate ...
Beneath the ocean's surface, a virus is hijacking the metabolism of one of the most abundant organisms on Earth.The marine cyanobacterium Prochlorococcus marinus is the dominant photosynthet...
Forests in the eastern United States that are structurally complex -- the arrangement of vegetation is varied throughout the physical space -- sequester more carbon, according to a new study in Ecolog...
For most plants, carbon dioxide acts like a steroid: the more they take in, the bigger they get. But in a new study, scientists at the Smithsonian Environmental Research Center, Villanova University a...
In another feat of bioengineering, Caltech's Frances Arnold, the Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry, and her team have created bacteria that can, for the ...
Nearly half of the organic carbon stored in soil around the world is contained in Arctic permafrost, which has experienced rapid melting, and that organic material could be converted to greenhouse gas...
Trees in tropical forests are well known for removing carbon dioxide from the air and storing the potent greenhouse gas as carbon in their leafy branches and extensive roots. But a new analysis led by...
Background: Vitamin B-12 (cobalamin) deficiency may produce severe neurologic and hematologic manifestations. Approximately 20–25% of circulating cobalamin binds to transcobalamin 2 (TCN2), which is r...
In the summer of 2012, two undergraduate students tackled a problem that plant ecology experts had overlooked for 30 years. The students demonstrated that different plant species vary in how they take...
The ocean sequesters massive amounts of carbon in the form of “dissolved organic matter,” and new research explains how an ancient group of cells in the dark ocean wrings the last bit of energy from c...
Background: Circulating concentrations of biomarkers that are related to vitamin status vary by factors such as diet, fortification, and supplement use. Published biomarker concentrations have also be...
Microbes in streams flowing on the surface of glaciers in the Arctic and Antarctic may represent a previously underestimated source of organic material and be part of an as yet undiscovered "dynamic l...
Metabolism of one-carbon (C1) compounds is shared by all living organisms today, yet microorganisms growing on one-carbon compounds established C1 metabolism as a major driver of global elemental cycl...
Picosecond mid-IR pump−probe measurements of vibrational relaxation (VR) of CO bound to the active sites of wild-type and mutant myoglobins (Mb) reveal that an approximately linear relationship ...
The carbon monoxide (CO) binding constants of human myoglobin (Mb) and several single-site mutants have been determined using two different methods. In the kinetic method, which is commonly used for t...
