2 side threadsThe Bacterial Flagellar Motor
Many bacteria swim with a true rotary motor: an ion-powered molecular machine in the cell envelope that spins a helical flagellum like a propeller. See how its parts fit together and turn.
1 side threadTokamaks: Holding Star-Hot Fuel in a Magnetic Doughnut
How do you hold fuel at 100 million degrees without wrecking its container? A tokamak keeps fusion plasma off its walls with twisted magnetic fields inside a doughnut-shaped chamber.
1 side threadHow the Universe Makes Gold
The gold in a ring was forged before the Sun existed, in some of the universe’s most violent events. Follow how ordinary stars fall short and colliding dead stars may finish the job.
Two Slits, One Quantum Surprise
Fire electrons one at a time at two slits and the dots still build up into bright and dark bands. The double-slit experiment shows why quantum probabilities don’t add up like ordinary odds.
What Would the Economy of a Type II Civilization Look Like?
A civilization harnessing the full power of its star could have cheap energy, automated industry and cities in space. Yet all that energy leaves surprisingly much about everyday economic life undecided.
