TL;DR: The National Spherical Torus Experiment (NSTX) is being built at the Princeton Plasma Physics Laboratory to test the fusion physics principles for the spherical torus (ST) concept at the MA level as discussed by the authors.

TL;DR: In this paper, strong magnetohydrodynamic activity has been observed in PDX neutral-beam-heated discharges and is associated with a significant loss of fast ions and a drop in neutron emission.
Journal ArticleDOI
Adipsin: a circulating serine protease homolog secreted by adipose tissue and sciatic nerve
Kathleen S. Cook,Hye Yeong Min,David W. Johnson,Robert J. Chaplinsky,Jeffrey S. Flier,Clayton R. Hunt,Bruce M. Spiegelman +6 more
TL;DR: Because of the apparent restriction of adipsin synthesis to tissues highly active in lipid metabolism, its presence in serum, and its modulation in altered metabolic states, this molecule may play a previously unrecognized role in systemic lipid metabolism or energy balance.
Journal ArticleDOI
Plant communities affect arbuscular mycorrhizal fungal diversity and community composition in grassland microcosms
David W. Johnson,David W. Johnson,Philippe Vandenkoornhuyse,Jonathan R. Leake,Lucy Gilbert,Rosemary E. Booth,J. Philip Grime,J. Peter W. Young,David Read +8 more
TL;DR: The unexpectedly high diversity in the bare soil and sedge monoculture likely reflects differences in the modes of colonization and sources of inoculum in these treatments compared with the assemblages containing established AM-compatible plants.
