Episode notes

The chemistry of indoors looks rather different to outdoors there's less sunlight for example. There are lots of unusual surfaces indoors that we don't really understand. Every home, every room, every business and every school is going to be slightly different. So how do we provide good science-based advice to help get good indoor air quality when we've got such a wide range of different environments?

0:46 The mysterious ring in the distant Solar System

Quaoar is a small, rocky object that lies beyond Neptune’s orbit. In an unexpected discovery, researchers have shown that this object has its own orbiting ring, similar to those seen encircling planets like Saturn. However, Quaoar’s ring shouldn’t exist, as it is at a distance far outside the theoretical limit at which rings are thought to be stable, and researchers are trying to figure out why.

09:26 Air pollution

Exposure to polluted air has been linked to millions of deaths each year. But while much is known about the sources and impacts of outdoor air pollution, significantly less is understood about the pollution that people are exposed to indoors, despite it causing a significant health burden. In a Comment article for Nature, a group of researchers argue for more research in order to inform future public health initiatives.
