Glad to share the work of @yli18smc.bsky.social and co on Lamassu, a bacterial defense system related to Rad50/Mre11 (RM). While RM carefully trims DNA ends for repair, Lamassu chops up the host chromosome. Our study reveals how it is regulated to minimize damage, activating only during infection.

Once upon a time, in the late 1800s, people in Japan got really into breeding mice.
Coloured mice. Patterned mice. Even mice that danced.
They became known as Japanese Fancy Mice, and that caught the attention of researchers in Europe and America, who imported them for study.
