Two waves of massive stars running away from the young cluster R136.

Massive stars are predominantly born in stellar associations or clusters. Their radiation fields, stellar winds and supernovae strongly impact their local environment. In the first few million years of a cluster's life, massive stars are dynamically ejected and run away from the cluster at high speed.

A magnetic massive star has experienced a stellar merger.

Massive stars (those ≥8 solar masses at formation) have radiative envelopes that cannot sustain a dynamo, the mechanism that produces magnetic fields in lower-mass stars. Despite this, approximately 7% of massive stars have observed magnetic fields, the origin of which is debated. We used multi-epoch interferometric and spectroscopic observations to characterize HD 148937, a binary system of two massive stars.

Engaging with the Private Sector for Noncommunicable Disease Prevention and Control: Is it Possible to Create "Shared Value?".

Noncommunicable diseases (NCDs) are the leading cause of premature mortality worldwide. Corporate interests are sometimes well-aligned with public health, but profiteering from the consumption of products that are known to be the major contributors to the noncommunicable disease burden undermines public health. This paper describes the key industry actors shaping the NCD landscape; highlights the unhealthy commodities' impact on health and the growing burden of NCDs; and outlines challenges and opportunities to reduce exposure to those risk factors.

Landscape Analysis of Nutrition-sensitive Agriculture Policy Development in Senegal.

Background: Unlocking the agricultural potential of Africa offers a genuine opportunity to address malnutrition and drive development of the continent.

Objective: Using Senegal as a case study, to identify gaps and opportunities to strengthen agricultural policies with nutrition-sensitive approaches.

Methods: We carried out a systematic analysis of 13 policy documents that related to food production, agriculture, food security, or nutrition.

Climate change and nutrition: creating a climate for nutrition security.

Background: Climate change further exacerbates the enormous existing burden of undernutrition. It affects food and nutrition security and undermines current efforts to reduce hunger and promote nutrition. Undernutrition in turn undermines climate resilience and the coping strategies of vulnerable populations.

Determinants of high vitamin A supplementation coverage among pre-school children in Mali: the National Nutrition Weeks experience.

Objectives: To assess vitamin A supplementation (VAS) coverage of children aged 6-59 months and the factors that favour or limit this coverage during the National Nutrition Weeks in Mali.

Design: Cross-sectional study. Interviews about demographic factors and children's adherence to the vitamin A capsule distribution programme were conducted.
