Our resident science guy Joe Johnson brings us some science stories that caught his eye this week:
- A sneaky bird that lays its eggs in another bird’s nest and lets someone else do the parenting — we’re looking at the conniving cowbird
- A new interstellar object has entered our solar system, and it’s moving fast
- And beneath our feet, things are shifting. Literally. Joe explains what the tectonic movement in East Africa could mean for the future of the continent.
