In a first, researchers image adaptive immune systems at work in fish

A new study from researchers at the University of Wisconsin–Madison offers a first-of-its-kind visual of a non-mammal species’ adaptive immune system in action. The advance holds potential implications for a range of scientific aims, from improving wildlife vaccines to better understanding fundamental disease processes and possibly the evolution of adaptive immunity itself.

Weizmann Institute Scientists Grow Advanced Mouse Embryos Outside the Uterus

In a first, the Weizmann Institute’s Prof. Jacob Hanna and his group have grown mouse embryos in an artificial uterus. The feat allows scientists to study the early stages of development, with potential implications that include understanding why implantations fail and the gestational conditions behind developmental disorders, as well as reduced need for laboratory animals.
