Breakthrough in Mapping Mojave Poppy Bee Genome
Researchers have achieved a significant breakthrough in understanding the genetic makeup of the Mojave poppy bee, a crucial pollinator in the eastern Mojave Desert. The ‘Beenome100’ project successfully mapped the genome of Perdita meconis, a species known for thriving in drought conditions. This achievement aims to provide insights into how genetic variations impact bee resilience to environmental changes, aiding in conservation efforts and sustainable bee management.
Ancient Plasmodium Genomes Shed Light on History of Human Malaria
Ancient Plasmodium genomes shed new light on the history of human malaria, revealing insights into the origins and spread of the disease. The study utilized high-coverage ancient genome-wide data spanning 5,500 years, showing early presence of P. vivax and P. falciparum in Eurasia. European colonizers likely brought P. vivax to the Americas, while the slave trade introduced P. falciparum. Surprisingly, P. falciparum was found in the high-altitude Himalayas, challenging previous assumptions. This research paves the way for palaeo-epidemiological studies, offering valuable insights into the historical impact of Plasmodium parasites.
