Director of perfumer Floris, Edward Bodenham, holds a pipette of vanilla as he mixes ingredients in his store in central London, Britain, August 19, 2015. Floris, established in 1730, holds a warrant as perfumer to Queen Elizabeth. Every year Queen Elizabeth grants about 20 royal warrants, the gold emblem of the British monarchy, in a practice dating back to medieval times. The warrant holders can display the certificate and use the royal coat of arms in their marketing. The warrants lasting five years can help businesses break into new markets overseas, using their role as supplier to the royal family as a gauge of quality. On September 9, Queen Elizabeth will overtake Queen Victoria as Britain's longest-serving monarch. Picture taken August 19, 2015. REUTERS/Toby Melville

Pipettes are placed near a rat brain sample for an experiment in a lab of the Blue Brain Project at the Brain Mind Institute of the Swiss Federal Institute of Technology (EPFL) in Ecublens, near Lausanne May 9, 2011. If selected from amongst six other candidates by the Future and Emerging Technologies (FET) Flagship Program launched by the European Commission, the Blue Brain Project will upgrade to become the Human Brain Project and will receive funding up to 100 million euros a year for 10 years. The final decision will take place in April 2012. The goal of the Blue Brain Project is to reconstruct the brain piece by piece and build a virtual brain in a supercomputer.
