- Scientists studied mice immune cells called B cells carefully.
- B cells are in germinal centers in mice normally.
- There the B cells change and compete rapidly.
- The goal is to help B cells work.
- Researchers watched many germinal centers at once closely.
- Sometimes one B cell type took over quickly.
- The system favors helpful B cell changes.
- They removed weak B cells very quickly.
- The study changes old ideas about germinal centers.
- The results may affect future research worldwide.

Study finds tuna traits evolved slowly after asteroid
A new study shows that tunas and their relatives did not gain large size and warm-bloodedness immediately after the asteroid strike 66 million years ago. Traits evolved independently in different lines over many millions of years.
