Zika, the mosquito-born virus that shrinks babies’ brains, continues to alarm scientists as they learn more about how it can be transmitted from person to person. Earlier this week, someone in Texas got the virus from sex, and today, a Brazilian government health institute reported that it discovered for the first time the presence of active Zika virus in urine and saliva samples.
If British scientists have their way, mutant mosquitoes will soon destroy the Florida Keys. Well, not exactly. But it's a possibility, or at least something to to think about, according to the 90,000 residents who have signed a petition. The genetically-modified mosquitoes are designed to resist the spread of Dengue fever, which is apparently a concern these days in the Keys.
