After the September 2011 execution of Troy Davis, believed by many to be innocent, Richard Dieter, the director of the Death Penalty Information Center, said this case was a clear wake-up call to politicians across the United States. He said: "They weren't expecting such passion from people in opposition to the death penalty. There's a widely held perception that all Americans are united in favor of executions, but this message came across loud and clear that many people are not happy with it." Brian Evans of Amnesty International, which led the campaign to spare Davis's life, said that there was a groundswell in America of people "who are tired of a justice system that is inhumane and inflexible and allows executions where there is clear doubts about guilt". He predicted the debate would now be conducted with renewed energy.

Who was the Death Penalty Information Center director?

Uranium was also used in photographic chemicals (especially uranium nitrate as a toner), in lamp filaments for stage lighting bulbs, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes. Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy, to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses, isolated cell organelles and macromolecules.

Along with leather, what industry uses uranium in dyes and stains?
Answer: wood

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.

Who purchased the rights to the tantalum light filament from Siemens?
Answer:
General Electric
