Genetic study tracks start of Zika's invasion of Americas back to 2013

A pair of Aedes albopictus mosquitoes are seen during a mating ritual while the female feeds on a blood meal in a 2003 imageThe Zika virus currently sweeping through the Americas looks to have hitched a ride on a plane into Brazil in 2013 and begun its invasion of the continent from there, scientists said on Thursday. In the first genome analysis of the current Zika epidemic, which has been linked in Brazil to cases of birth defects known as microcephaly, researchers said the virus' introduction to the Americas almost three years ago coincided with a 50 percent rise in air passengers from Zika-affected areas. The strain of the virus circulating in the current outbreak is most closely related to one from French Polynesia, the scientists said, although it is also possible that Zika was introduced separately to the Americas and French Polynesia from South East Asia.

A thin black line against a sea of white is all that connects Antarctica's Concordia research station to life. Concordia research station is known as the "remotest base on Earth." It's so far from other humans — 372 miles (600 km) from the nearest base, Vostok in Russia — that it's more remote than the International Space Station, according to the ESA. The station is located on the Antarctic Plateau at an elevation of 10,499 feet (3,200 meters).
