The ghost of pandemics past: revisiting two centuries of influenza in Sweden
Previous influenza pandemics are usually invoked in pandemic preparedness planning without a thorough analysis of the events surrounding them, what has been called the 'configuration' of epidemics. Historic pandemics are instead used to contrast them to the novelty of the coming imagined plague or as fear of a ghost-like repetition of the past. This view of pandemics is guided by a biomedical f...
متن کاملDilated cardiomyopathy: a ghost from the past.
Case Report A 42-year-old woman presented herself to the emergency services in cardiogenic shock. She had a history of progressively worsening breathlessness for the past year; however, no medical evaluation had been performed earlier. At presentation, her pulse rate was 110 beats per minute, regular, and low volume, and her blood pressure was 90/70 mm Hg. On auscultation, third heart sound was...
متن کاملStream biodiversity: the ghost of land use past.
The influence of past land use on the present-day diversity of stream invertebrates and fish was investigated by comparing watersheds with different land-use history. Whole watershed land use in the 1950s was the best predictor of present-day diversity, whereas riparian land use and watershed land use in the 1990s were comparatively poor indicators. Our findings indicate that past land-use acti...
متن کاملResurrecting the ghost of competition past with dormant zooplankton eggs.
A common prediction of evolutionary theory is that the strength of interspecific competition should decline over time among sympatric populations of competing species. Here we provide experimental evidence of historical declines in competition effects among competing zooplankton populations. Using diapausing eggs, we resurrected clones of three species of zooplankton obtained from different per...
متن کاملCRISPR-mediated phage resistance and the ghost of coevolution past
The past is never dead. It's not even past William Faulkner (1951). Bacteria can acquire heritable immunity to viral (phage) enemies by incorporating phage DNA into their own genome. This mechanism of anti-viral defence, known by the acronym CRISPR, simultaneously stores detailed information about current and past enemies and the evolved resistance to them. As a high-resolution genetic marker t...
