1918 Spanish Flu Mystery Solved

Scientists appear to have solved an enduring mystery surrounding the 1918 outbreak of Spanish flu which killed millions worldwide.

Estimates say the epidemic took 50 million lives, more than the First World War. Unlike most bird flu strains, it was lethal amongst young, healthy people.

Canadian lab reconstructed the Spanish flu virus from human tissues preserved in the Alaskan permafrost and infected macaque monkeys. Their findings were reported on Thursday in the journal Nature, and should give a better view of how the virus killed humans than earlier work with infected mice.
It turns out that the H1N1 Spanish flu virus (the current bird flu threat is from H5N1, the nomenclature derived from the proteins which coat the virus) killed 50 million by over-stimulating their immune system, causing the lungs to inflame and rapidly fill with liquid. Lead author Professor Yoshihiro Kawaoka of the University of Wisconsin said: "Essentially people are drowned by themselves."
So a young, healthy person with a young, healthy immune system would be a ripe victim for the 1918 strain. Associated Press reports co-author Michael Katze, of the University of Washington, said: "It was the robustness of the immune system that helped victimize them."

Dead Birds Fall from the Sky in Australia and Texas

THOUSANDS of birds have fallen from the skies over Esperance and no one knows why.
Is it an illness, toxins or a natural phenomenon? A string of autopsies in Perth have shed no light on the mystery.
All the residents of flood-devastated Esperance know is that their "dawn chorus" of singing birds is missing.
The main casualties are wattle birds, yellow-throated miners, new holland honeyeaters and singing honeyeaters, although some dead crows, hawks and pigeons have also been found.
Wildlife officers are baffled by the "catastrophic" event, which the Department of Environment and Conservation said began well before last week's freak storm.
On Monday, Esperance, 725km southeast of Perth, was declared a natural disaster zone

AUSTIN — The mysterious deaths of more than 60 grackles, sparrows and pigeons that touched off a dramatic shutdown of a dozen streets along Congress Avenue ended in a cliffhanger Monday, with officials still uncertain about what killed the birds.
