Researchers discover new nitrogen source in Arctic

(Bigelow Laboratory for Ocean Sciences) Scientists have revealed that the partnership between an alga and bacteria is making the essential element nitrogen newly available in the Arctic Ocean. The microbial process of 'nitrogen fixation' converts the element into a form that organisms can use, and was discovered recently in the frigid polar waters. This shift may be a result of climate change and could affect global chemical cycles, according to the study published in the Proceedings of the National Academy of Sciences.

CONCLUSION: The small amount of evidence that is currently available suggests that presbycusis is underdiagnosed and under- treated in Germany. Early detection by physicians of all specialties, followed in each case by a specialized differential diagnostic evaluation, is a desirable goal. PMID: 31196393 [PubMed - in process]

CONCLUSION: The causes of visual impairment are manifold. Loss of vision is often the combined effect of multiple pathological factors. The etiology of visual impair- ment is thus a more complex matter than is commonly assumed. PMID: 31196384 [PubMed - in process]
