In the forests of Borneo in South-East Asia, a carnivorous pitcher plant, Nepenthes rafflesiana, lures, traps and digests small animals, mainly insects. As part of the lure, the pitchers copy flowers in a variety of ways, producing nectar as well as using bright colours and ultraviolet patterns. A study published in the Journal of Ecology has shown that this mimicry also includes a range of floral scents to trick insects to their demise.

Ten miles off the Californian coastline, at the bottom of the Santa Barbara channel, domes rise from the Pacific Ocean floor. A paper published on-line in the journal Nature Geoscience identified these as a series of unusual underwater volcanoes.
The Application Notebook
In ion chromatography, the presence of a large amount of matrix ions makes quantification of the target ions difficult. Selective removal of matrix ions - matrix elimination - can be performed by treating a sample with a solid-phase extractant. Halides can be removed by precipitation with silver, which is present as a counterion in a cation-exchange resin. A subsequent treatment with a cation-trapping column removes residual dissolved silver ions.
