• Chemical happenings on the web - This week, the Alchemist hears how starfish mucus could be the next lead in anti-inflammatory drug research, while chromatography uses macrocyclic starch molecules to go green. News of an arsenic-based bacteria is greatly exaggerated (allegedly) but energy-rich waste water may be the fuel of the future. In organic supramolecular ionic chemistry, the pyrrole unit helps a Japanese team synthesis nanostructured fibrous and soft materials. Finally, the 2012 ACS president is announced.
• A Christmas chemical - A tale of chemical and microbes for Christmas…
• LEDs not so green, after all - Toxic chemicals could leach into landfill from waste LEDs, according to a new study, meaning this low-energy lighting alternative may not be so green as we thought…
• Bottled up confusion - Can two small molecules be trapped in the same molecular cavity at the same time? A storm in a microscopic teacup is brewing that could lead to major changes in the way chemists deposit crystal structure data.
