2/4/14 Health News Salmonellosis NOT Prevented by Just Cooking - Molecular Nano Spies - Bubonic Plague Could Return

SALMONELLOSIS PREVENTION: JUST COOK IT
When Michael Taylor declared Escherichia coli O157:H7 an adulterant in ground beef, there were howls of, “Just cook it,” from the industry and from within FSIS. For example, two members of FSIS’ Microbiology Division were adamant in their declaration that cooking was sufficient and quoted from the 1975 American Public Health Association, et al., Appellants,...

Molecular Nano-spies to Make Light Work of Disease Detection
A world of cloak-and-dagger pharmaceuticals has come a step closer with the development of stealth compounds programmed to spring into action when they receive the signal. Researchers at the University of Nottingham’s School of Pharmacy have designed and tested large molecular complexes that will reveal their true identity only when they’ve reached their intended target, like disguised saboteurs working deep behind enemy lines. What is then exposed – an active pharmaceutical compound, a molecular tag to attach to diseased tissue, or a molecular beacon to signal activation – depends on what function is needed.

Bubonic Plague Could Return, Warn Scientists After Discovering New Strain Of Black Death Bacterium

A similar form of bubonic plague to the Black Death could make an unwelcome reappearance on Earth, according to researchers. Scientists studying the Plague of Justinian (AD 541–542), one of the most lethal pandemics in human history, which wiped out half of the world's population, extracted the teeth of two 1,500-year-old victims. By doing so, they were able to trace the genetics of the ancient plague, concluding that the Justinian outbreak was caused by a different bacterial strain from that responsible for the later Black Death (AD 1348–50).
