Difference between Bioscience and Lifescience
I agree with the comments and largely see them as the same thing, and many dictionaries would probably agree with this. However, in practical use (from my experience) Life science is used somewhat more broadly (everything from ecology and agricultural science to genomics and biochemisty), while Bioscience is more often applied to "whiter" lab-based biology and more technical applications (biotechnology, genetics, etc.). Personally, I would feel comfortable to label my research as life science but a bit more uneasy with bioscience. However, the terms are so vague that I wouldn't pass judgement on the content of research just based on these labels.
