Therefore, Ludwig-Maximilians-Universitaet (LMU) in Munich researchers argue that bovine embryos might well be a better model for early human development than the mouse system. Many fundamental aspects of the early stages of embryonic development in humans are found to be conserved […]

Researchers create models that predict spread of flu in the United States

February 27, 2018 Using several large datasets describing health care visits, geographic movements and demographics of more than 150 million people over nine years, researchers at the University of Chicago have created models that predict the spread of influenza throughout the United States each year.
