Sulfur enhances carbon storage in the Black Sea: Study finds new explanation for the accumulation of organic compounds in oxygen-depleted marine areas
The Black Sea is an unusual body of water: below a depth of 150 metres the dissolved oxygen concentration sinks to around zero, meaning that higher life forms such as plants and animals cannot exist in these areas. At the same time, this semi-enclosed sea stores comparatively large amounts of organic carbon. A team of […]
Eye imaging technology breaks through skin by crossing beams: New approach to optical coherence tomography increases its depth of view in biological tissues
Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin. The gold standard for imaging and diagnosing diseases within the retina, OCT has yet to find widespread use as an imaging technique for other parts of the body due to its […]
