Why did SARS only become an epidemic in China and in Toronto, the part of Canada where many Chinese emigrants live? Scientists have found a genetic susceptibility to SARS that explains this puzzle.

Maggie Fox writes that a variant in an immune system gene called human leukocyte antigen, or HLA, makes certain patients much more likely to develop the life-threatening symptoms of SARS. This gene variant is common in people of southern Chinese descent.

Israel is alarmed by the failure of the international community to move against Iran.
