Exploring the use of solid fuels for cooking and household air pollution in informal settlements through photovoice: The Fuel to Pot study in Ndirande (Malawi) and Mukuru (Kenya).

Introduction: Worldwide, 2.4 billion people rely on solid fuels such as wood or charcoal for cooking, leading to approximately 3.2 million deaths per year from illnesses attributable to household air pollution.

Dynamic co-clustering and self-sorting in interactive protocell populations.

The design and implementation of collective actions in model protocell communities is an on-going challenge in synthetic protobiology. Herein, we covalently graft alginate or chitosan onto the outer surface of semipermeable enzyme-containing silica colloidosomes to produce hairy catalytic protocells with pH-switchable membrane surface charge. Binary populations of the enzymatically active protocells exhibit self-initiated stimulus-responsive changes in spatial organization such that the mixed community undergoes alternative modes of electrostatically induced self-sorting and reversible co-clustering.

Investigating disease awareness of cutaneous leishmaniasis in rural Sri Lanka to inform public health services: a cross-sectional study.

Objective: To assess community awareness of cutaneous leishmaniasis (CL) in a disease-endemic district in Sri Lanka.

Design: Population-based cross-sectional study.

Setting: This study was conducted in selected 158 Grama Niladhari divisions covering all the 22 Divisional Secretariat areas of the Anuradhapura district, Sri Lanka.
