Science Stories with Joe Johnson

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.
