“Having a cold is a nuisance, but not dangerous. Right? Wrong. Sometimes it can turn deadly. Last year, 140 people in the US were killed by the kinds of virus that usually cause nothing more serious than sniffs and sneezes. In fact, we are surprisingly ignorant about the causes of the world’s most common disease. But new technologies are changing that – and turning up cold viruses that are completely new to science.” (New Scientist via WaccoBB)
