This week’s Alchemist

March 1, 2013 – 6:28 pm

Heavy metal lighting catches the eye of The Alchemist this week along with the work of a cubist "decorator." In solar energy conversion a new composite could absorb photons to split water and make hydrogen in an entirely new way breaking 70 years of tradition. We also hear about geochemical clues to the existence of a lost continent buried beneath the Indian Ocean. Also, in view is the chilly world of high-temperature superconductors. Finally, NSFW, a new National Science Foundation (NSF) award for chemical Work.

Copycat flags help aliens avoid mouse immune system

My latest news item for Chemistry World

Synthetic peptide flags added to therapeutic and diagnostic agents can trick the immune system into ignoring them, according to US researchers. The peptides emulate the properties of the protein markers that classify cells as self rather than ‘alien so they are not consumed by white blood cells.

Chemistry news roundup on ChemWeb

February 18, 2013 – 9:05 am

The Alchemist learns this week of analysis fit for a king as British scientists reveal the remains of the most infamous son of York, Richard the Third. In the world of materials, graphitic oxides are shown to behave like water-logged clays at very low temperatures while cutting the mustard could lead to more efficient farming and perhaps new medical approaches to metabolic disorders. A conducting polymer device has been described that could charge up a mobile phone by tapping into your body heat, while a health test for oranges might improve the quality of fruit juice and save trees from dieback. Finally, the Japan Prize is awarded to two ex-IBM scientists for their pioneering work in the 1970s that led to the technique of choice for making so-called silicon chips.
