QUES: Chromobacterium violaceum and Pseudomonas fluorescens can both mobilize solid copper, as a cyanide compound. The ericoid mycorrhizal fungi associated with Calluna, Erica and Vaccinium can grow in copper metalliferous soils. The ectomycorrhizal fungus Suillus luteus protects young pine trees from copper toxicity. A sample of the fungus Aspergillus niger was found growing from gold mining solution; and was found to contain cyano metal complexes; such as gold, silver, copper iron and zinc. The fungus also plays a role in the solubilization of heavy metal sulfides.

QUES: In September 1939, Britain and the self-governing Dominions, but not Ireland, declared war on Nazi Germany. George VI and his wife resolved to stay in London, despite German bombing raids. They officially stayed in Buckingham Palace throughout the war, although they usually spent nights at Windsor Castle. The first German raid on London, on 7 September 1940, killed about one thousand civilians, mostly in the East End. On 13 September, the King and Queen narrowly avoided death when two German bombs exploded in a courtyard at Buckingham Palace while they were there. In defiance, the Queen famously declared: "I am glad we have been bombed. It makes me feel we can look the East End in the face". The royal family were portrayed as sharing the same dangers and deprivations as the rest of the country. They were subject to rationing restrictions, and U.S. First Lady Eleanor Roosevelt remarked on the rationed food served and the limited bathwater that was permitted during a stay at the unheated and boarded-up Palace. In August 1942, the King's brother, Prince George, Duke of Kent, was killed on active service.

On what date in August 1942 was Prince George killed?
