Predation risk affects reproductive physiology and demography of elk.
Elk (Cervus elaphus) in the Greater Yellowstone Ecosystem alter patterns of aggregation, habitat selection, vigilance, and foraging in the presence of wolves (Canis lupus). Antipredator behaviors like these can reduce predation risk but are also likely to carry costs. Data from five elk populations...

Putting women and girls at the center of development.
The development field needs to be more serious about gender inequities and women's empowerment. By ignoring gender inequities, many development projects fail to achieve their objective. And when development organizations do not focus on women's empowerment, they neglect the fact that empowered women...
Intersection of population variation and autoimmunity genetics in human T cell activation.
We know little about its variation in humans and its genetic or environmental roots. We analyzed gene expression in CD4(+) T cells during unbiased activation or in T helper 17 (T(H)17) conditions from 348 healthy participants representing European, Asian, and African ancestries. We observed interind...
Riboswitches. Sequestration of a two-component response regulator by a riboswitch-regulated noncoding RNA.
We show that in Listeria monocytogenes, a riboswitch that binds vitamin B12 controls expression of a noncoding regulatory RNA, Rli55. Rli55, in turn, controls expression of the eut genes, whose products enable ethanolamine utilization and require B12 as a cofactor. Defects in ethanolamine utilizatio...
