Skin inflammation is often accompanied by systemic disease, yet the pathways that regulate this escalation are little known. Here authors show that transgenic expression of human CD1a in mice leads to the escalation of experimental skin inflammation and systemic inflammatory disease, and the generalized symptoms could be alleviated by blocking antibodies developed against CD1a.

The authors report genetic, archaeological and stable isotopic data from two late Palaeolithic individuals in Britain, from Gough's Cave and Kendrick's Cave.

The inability of tyrosine kinase inhibitors to eliminate quiescent leukaemic stem cells (LSC) in chromic myeloid leukaemia (CML) results in recurrence. Here, the authors identify a reliance of CML LSCs on low P53 expression for self-renewal and therapeutically target this by combining an MDM2 inhibitor with TKI in preclinical models of CML.

Isolating the relationships between biodiversity and ecosystem functioning in natural ecosystems is challenging. Here, the authors apply a causal inference approach to observational data from grasslands and find a negative effect of biodiversity on productivity driven by non-native and rare species.

Eutrophication has been shown to weaken diversity-stability relationships in grasslands, but it is unclear whether the effect depends on scale. Analysing a globally distributed network of grassland sites, the authors show a positive role of beta diversity and spatial asynchrony as drivers of stability but find that nitrogen enrichment weakens the diversity-stability relationships at different spatial scales.

A NutNet experiment in 57 grasslands across six continents shows that when herbivores are excluded from grasslands with a long coevolutionary history of grazing plant diversity is reduced, while in grasslands without a long grazing history the evolutionary history of the plant species regulates the response of plant diversity.
