Mosquito genetics may explain why Zika virus outbreaks are rare in Africa: climate change could shift the balance
Mosquitoes that bite people. Credit: Greg Murray / Louis Lambrechts Africa’s low incidence of the Zika virus may be due to a surprising factor: the genetic makeup of local mosquito populations, a study has found. Research by scientists at Princeton University’s High Meadows Environmental Institute (HMEI), the Pasteur Institute, and the University of California, San Diego, reveals the causes of…

Alarming temperature rises expected in the Middle East and North Africa
Evaluation of climate models. Between CMIP5-unadjusted dataset and ERA5 dataset (top row), CMIP6-unadjusted dataset and ERA5-Land dataset (second row), CMIP5-adjusted dataset and ERA5 dataset (third row) indicates the average bias of . CMIP6-Adjusted and ERA5-Land datasets (bottom row). Panels (a, c, e, g) and panels (b, d, f, h) show the summer and winter mean biases, respectively. Green polygons mark…

Researchers sequence oldest human DNA ever from South Africa
DNA double helix. Credit: Public Domain Researchers have reconstructed the genomes of two humans found in South Africa that lived about 10,000 years ago, providing a better understanding of the conditions in which people in the region lived, the study authors announced Sunday. Victoria Gibbon, professor of biological anthropology at the University of Cape Town (UCT), said the genetic sequence…
