Deep Eutectic Solvents Based on Natural Ascorbic Acid Analogues and Choline Chloride.

Deep eutectic solvents (DES) are one of the most promising green technologies to emerge in recent years given their combination of environmentally friendly credentials and useful functionalities. Considering the continued search for new DES - especially those that exemplify the aforementioned characteristics, we report the preparation of DES based on natural analogues of l-ascorbic acid for the first time. The onset of eutectic melting occurred at temperatures far below the melting point of the individual components and resulted in the generation of glass forming fluids with glass transition temperatures, viscosities and flow behavior that are comparable to similar systems.

Teaching report: the use of Drosophila melanogaster larval thermosensitive escape behaviour as a model system to demonstrate sensory function.

We describe how a novel thermosensitive escape behaviour in Drosophila larvae can be used to teach neurobiology principles to both undergraduates and school children. The assays are inexpensive, robust and reliably accurate employing apparatus readily available in most science classrooms. The use of Drosophila avoids the employment of vertebrate models and the ethical and expense issues that this entails.
