Sir Hans Adolf Krebs
Born 25 Aug 1900; died 22 Nov 1981 at age 81
German-British biochemist who shared (with Fritz Lipmann) the 1953 Nobel Prize for Physiology or Medicine for the discovery in living organisms of the series of chemical reactions known as the tricarboxylic acid cycle (also called the citric acid cycle, or Krebs cycle)—the basic system for the essential pathway of oxidation process within the cell. These reactions involve the conversion—in the presence of oxygen—of substances that are formed by the breakdown of sugars, fats, and protein components to carbon dioxide, water, and energy-rich compounds. The Krebs cycle explains two simultaneous processes: the degradation reactions which yield energy, and the building-up processes which use up energy.
Oldest European bat
In 1999, the oldest wild bat in Europe recorded to date was a 33-year-old male lesser mouse-eared bat according to a claim published in The Independent newspaper (London). Two Swiss researchers from the University of Lausanne found the bat in the eaves of the church, in south-west Switzerland. An earlier oldest bat record in the U.S. was 24-yr-old little brown bat found on 30 Apr 1960.
Mercury ban in flu vaccines
In 2004, thimerosal-containing influenza vaccines were banned from use in California. The governor, Arnold Schwarzenegger, was reacting more to public advocacy groups than the weight of medical opinion. Thimerosal, containing an ethylmercury compound has been used in vaccines in microgram quantities to prevent life-threatening bacterial contamination. In 2004, a report by the Immunization Safety Review Committee of the Institute of Medicine stated that the benefits of vaccination are proven and the hypothesis of susceptible populations is presently speculative. After considering available medical studies from several countries, the report rejected any connection between thimerosal-containing vaccines and autism. Neverthless, some lay persons convince themselves otherwise.
