In 2003, the human genome was declared complete, but in reality, the draft was missing about 8 percent of the genome (the hardest-to-sequence) regions. Finally, this May, a group of researchers posted a preprint of the first truly completed genome, a readout of all 3.055 billion letters across 23 human chromosomes.
Mosquito eggs places in the Florida Keys are expected to hatch thousands of genetically modified mosquitoes. The federally approved experiment studies the use of genetic engineering – rather than insecticides – to control disease-carrying mosquito populations.
During their "Nobel to Nobel" chat at the Spark 2021 conference, Jennifer Doudna, PhD, and Frances Arnold, PhD, touched on topics such as CRISPR, the ethics of genome editing, working on COVID-19, and winning the Nobel Prize. The two scientists also shared inspiring stories of being women in science clearing hurdles to achieve extreme success.
Researchers have grown the first mouse embryos outside a living womb. Published in Nature, the study sheds light on how mammal embryos can develop inside an artificial uterus and how genetic and environmental factors may play a part in its development.
