The clever use of gravity assist is unquestionably a success, but it doesn’t come without drawbacks, particularly when used to reach the outer solar system via Venus: the large increase of the mission duration and the need of travelling in the radiation-rich regions of the inner solar system...
Monoclonal antibodies are increasingly used to prevent and treat viral infections and are pivotal in pandemic response efforts. Antibody-secreting cells (ASCs; plasma cells and plasmablasts) are an excellent source of high-affinity antibodies with therap
