Excited to share our newest work! We asked whether RNA molecules need to be in a specific place in the cell to do their job. We found that a single RNA must reach the midbody, the structure that pinches two dividing cells apart, for cell division to finish efficiently. ๐งตโฌ๏ธ

Franzi Schimmer captured this Grizzly bear in Brooks Falls, Alaska just floating along, tippy-tapping down the river, browsing the salmon. Prior to hibernation, up to 40% of a bear's body mass is fat, which is less dense than water (~0.9 g/cm^2), so the murder-monster is also a floaty-boaty.
