The World Health Organization declared the mosquito-borne Zika virus a global public health emergency on February 1. Spreading in the Americas, the mosquito-borne disease has been associated with microcephaly in newborns. Read Georgetown professor John McNeill's thoughts on the ecology of mosquitoes and disease in the Americas in this CNN article.
Lake Poopó, Bolivia's second-largest lake, has dried up for the second time since 1990. Now over one month into the rainy season, water has yet to return. The lake is particularly exposed to climatic fluctuations due to its very shallow depth (9 feet).
“I don’t think we’ll be seeing the azure mirror of Poopó again. I think we’ve lost it,” one Bolivian scholar told the Associated Press.
Genetic mapping confirms that the parasite causing schistosomiasis was first carried from Africa to the Americas in the bodies of African slaves, further evidence of an environmental history of slavery. "Comparing the S. mansoni genomes suggests that flukes in West Africa split from their Caribbean counterparts at some point between 1117AD and 1742AD, which overlaps with the time of the 16th-19th Century Atlantic Slave Trade," Professor Joanne Webster of Imperial College London and the Royal Veterinary College said. "During this period more than 22,000 African people were transported from West Africa to Guadeloupe by French slave ships, and the fluke was carried with them."
