The African crested rat’s poisonous hairs studied by attenuated total reflection infrared spectroscopy

IR-23_06-FsThe African crested rat chews poisonous bark and then applies its saliva to specialised hairs which provide a most effective protection. Maxime Boulet-Audet and Chris Holland describe this and the use of infrared spectroscopy to learn more about this unusual animal. The new knowledge may even lead to new treatments for human cardiac conditions.

New broadband high-resolution ozone absorption cross-sections

UV-vis-23_6-F4sWith the threat of climate change, understanding the workings of our atmosphere is of crucial importance. Ozone is the most important trace gas in the stratosphere and troposphere and it is monitored by both satellite-borne and ground-based instruments. Accurate knowledge of ozone absorption cross-sections is vital for this work and described in this article.
