Does diet quality moderate the long-term effects of discrete but extreme PM exposure on respiratory symptoms? A study of the Hazelwood coalmine fire.

In 2014, a fire at an open cut coalmine in regional Victoria, Australia burned for 6 weeks. Residents of the nearby town of Morwell were exposed to smoke, which included high levels of fine particulate matter (PM). We investigated whether the long-term effects of PM on respiratory health were moderated by diet quality.

Conformal field theories in fractional dimensions.

We study the conformal bootstrap in fractional space-time dimensions, obtaining rigorous bounds on operator dimensions. Our results show strong evidence that there is a family of unitary conformal field theories connecting the 2D Ising model, the 3D Ising model, and the free scalar theory in 4D. We give numerical predictions for the leading operator dimensions and central charge in this family at different values of D and compare these to calculations of ϕ4 theory in the ϵ expansion.

Producing a successful malaria vaccine: innovation in the lab and beyond.

With approximately 225 million new cases and 800,000 deaths annually, malaria exacts a tremendous toll--mostly on African children under the age of five. Late-stage trials of an advanced malaria vaccine candidate--which, if approved, would become the world's first malaria vaccine--are under way, and it may be ready for use by 2015. This article recounts the pivotal roles in that achievement played by collaborations of nonprofit organizations, pharmaceutical companies, private and public donors, and countries whose citizens would benefit most directly from a vaccine.
