The universe is a deeply vexing place. Every breakthrough we make in our understanding of it begets more mysteries about how all this (gestures wildly) actually happened.
This week, we saw the first-ever image of a newborn great white shark; scientists figured out what’s really happening when insects fly around artificial lights; and mathematicians reversed the sprinkler. Click through for our top science stories of the week.
For 141 years, physicists like Richard Feynman have puzzled over a question of fluid flow: how would a sprinkler rotate if it were underwater, sucking in the stuff instead of spewing it? Now, a team of researchers has found an answer.
