Scientists working to understand the implications of Zika’s new prevalence in the Americas have found strong evidence that infection with the virus can cause fetal abnormalities and even miscarriage in pregnant women. On The Pump Handle, Liz Borkowski examines a series of studies conducted on Zika, including one which found the virus infected “most of the cortical neuron progenitors, which form the brain’s cortex” more quickly than other types of stem cell. This may be how the virus causes microcephaly, a birth defect resulting from abnormal brain development in the womb. On Discovering Biology in a Digital World, Sandra Porter leads a hunt for potential drugs against Zika by looking at the molecular level, comparing known drugs to the protein structures of the virus. And on Respectful Insolence, Orac questions whether DDT could play a role in fighting the outbreak.
