The role of sex work laws and stigmas in increasing HIV risks among sex workers
Globally HIV incidence is slowing, however HIV epidemics among sex workers are stable or increasing in many settings. While laws …
Article scientifique
Antimicrobial resistant enteric bacteria are widely distributed amongst people, animals and the environment in Tanzania
Antibiotic use and bacterial transmission are responsible for the emergence, spread and persistence of antimicrobial-resistant (AR) bacteria, but their relative …

Isolation of Angola-like Marburg virus from Egyptian rousette bats from West Africa
Marburg virus (MARV) causes sporadic outbreaks of severe Marburg virus disease (MVD). Most MVD outbreaks originated in East Africa and …
Article scientifique
El Niño-Southern oscillation and under-5 diarrhea in Botswana
Childhood diarrheal disease causes significant morbidity and mortality in low and middle-income countries, yet our ability to accurately predict diarrhea …
Article scientifique
High-resolution micro-epidemiology of parasite spatial and temporal dynamics in a high malaria transmission setting in Kenya
Novel interventions that leverage the heterogeneity of parasite transmission are needed to achieve malaria elimination. To better understand spatial and …
Article scientifique
Chaperone biomarkers of lifespan and penetrance track the dosages of many other proteins
Many traits vary among isogenic individuals in homogeneous environments. In microbes, plants and animals, variation in the protein chaperone system …

Edematous severe acute malnutrition is characterized by hypomethylation of DNA
Edematous severe acute childhood malnutrition (edematous SAM or ESAM), which includes kwashiorkor, presents with more overt multi-organ dysfunction than non-edematous …
Article scientifique
Templated dewetting of single-crystal sub-millimeter-long nanowires and on-chip silicon circuits
Large-scale, defect-free, micro- and nano-circuits with controlled inter-connections represent the nexus between electronic and photonic components. However, their fabrication over …
Article scientifique
The coincidence of ecological opportunity with hybridization explains rapid adaptive radiation in Lake Mweru cichlid fishes
The process of adaptive radiation was classically hypothesized to require isolation of a lineage from its source (no gene flow) …
Article scientifique
Insights into malaria susceptibility using genome-wide data on 17,000 individuals from Africa, Asia and Oceania
The human genetic factors that affect resistance to infectious disease are poorly understood. Here we report a genome-wide association study …

Global geochemical fingerprinting of plume intensity suggests coupling with the supercontinent cycle
Plate tectonics and mantle plumes are two of the most fundamental solid-Earth processes that have operated through much of Earth …
Article scientifique
Observation of quantum many-body effects due to zero point fluctuations in superconducting circuits
Electromagnetic fields possess zero point fluctuations which lead to observable effects such as the Lamb shift and the Casimir effect. …
Article scientifique
Noble gases confirm plume-related mantle degassing beneath Southern Africa
Abstract Southern Africa is characterised by unusually elevated topography and abnormal heat flow. This can be explained by thermal perturbation …
