...team of scientists from the U.S., Indonesia and Japan, led by virologist Yoshihiro Kawaoka at the University of Wisconsin - Madison, combined a strain of the deadly H5N1 avian virus with strains of H3N2 human seasonal flu, creating 254 new, mutated viruses. By injecting them in lab mice, researchers found that some of the hybrid viruses were both deadly (like bird flu) and transmissible (like seasonal human flu) - the kind of genetically mutated superflu viruses that experts have been warning about for decades.

...between humans only in rare cases, usually among family members in close conditions. But the fear has long been that if bird flu genetically mixed with human flu - in a process called reassortment, in which two flu viruses swap genes in an infected cell - it could create a new strain that is both deadly and transmissible, as illustrated by the new PNAS study. That's how many past pandemic viruses, including 2009 H1N1, were created, leading to new strains to which humans have no natural immunity...
...occurred to me that rehearsing loss to dull the loss might bring about the very loss I was hoping to avert.” This constant act of stagnant, empty rehearsal is emblematic of the psychological development in the novel—the characters constantly strain towards expression, retracting or repeating statements, but never move towards a new idea or significant development...
...Last year and this year...the total chaos in the economy has put enormous strain on families and students,” he said. “In the general population, the rate of depression, the rate of suicide, and the rate of drinking has risen enormously. Why would the student population be immune...
What probably did Tut in, says Pusch, was an immune system that was badly compromised by a particularly virulent strain of malaria combined with a degenerative bone disease that had already left him weak. "This is confirmed by images that show him sitting while shooting an arrow, which normally would have been done standing up," says Hawass. "He cannot stand." Indeed, more than 100 canes were found in the tomb when Tut's mummy was found in 1922, some of them showing signs of wear...
