Two new species of black coral are described herein: Leiopathes dumosa nov. sp. and Leiopathes brugleri nov. sp. Samples were collected between depths of 244 and 617 m on the North American continental slope between Texas and Florida, USA, and recognized in the family Leiopathidae Haeckel, 1896. L. dumosa nov. sp. is characterized by short stems and short branches forming bush-like colonies (usually less than 1 m tall and 0.25...

Dietary methionine restriction (MR) increases longevity by improving health. In experimental models, MR is accompanied by decreased cystathionine β-synthase activity and increased cystathionine γ-lyase activity. These enzymes are parts of the transsulfuration pathway which produces cysteine and 2-oxobutanoate. Thus, the decrease in cystathionine β-synthase activity is likely to account for the loss of tissue cysteine observed...
The semi-arid African Sahel region is highly sensitive to changes in monsoon precipitation, as much of the region’s workforce is employed in the agricultural industry (Hamro-Drotz and Programme 2011). Thus, studying the response of rainfall and aridity in this region to radiative perturbations is a matter of pressing humanitarian relevance. In addition, there is evidence to suggest that spatially asymmetric volcanic aerosols p...
