Branched glycerol dialkyl glycerol tetraethers (bGDGTs) are membrane-spanning lipids that likely stabilize membranes of some bacteria. Although bGDGTs have been reported previously in certain geothermal environments, it has been suggested that they may derive from surrounding soils since bGDGTs are known to be produced by soil bacteria. To test the hypothesis that bGDGTs can be produced by ther...

We have been favoured by Assistant Surgeon C. E. Smith, jr.u., of the 11th Hussars, with papers describing an interesting experiment regarding the efficacy of these springs in the treatment of rheumatism. As the papers have appeared in cxtenso in the Pioneer, we do not reproduce them. A number of men ?European and native soldiers?who had been attacked with rheumatism consequent on the exposure ...

Arsenic biogeochemistry has been studied extensively in acid sulfate-chloride hot springs, but not in acid sulfate hot springs with low chloride. In this study, Zhenzhuquan in Tengchong geothermal area, a representative acid sulfate hot spring with low chloride, was chosen to study arsenic geochemistry and microbial community structure using Illumina MiSeq sequencing. Over 0.3 million 16S rRNA ...
