Albert Einstein and Isidor Kohn
How scientists found out that we live in a cosmic aquarium.
Magnet levitating above a high-temperature superconductor, cooled with liquid nitrogen.
So far, two papers have been retracted, and a third is under investigation. Accusations of plagiarism appear convincing.

We bake pies for Pi Day, so why not celebrate other mathematical achievements.
impact crater
Many impact craters on Earth have been erased thanks to wind, water, and plate tectonics. But scientists have clever ways to find them.
The first "running machine" — later known as the bicycle — symbolizes a key design idea.
pi day cover image
It's the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
The nature of civilizational threats has changed in a mere decade.
crab pulsar remnant
We can't go back to the Big Bang, nor ahead to the heat death of the Universe. Nevertheless, here are today's natural temperature extremes.
"It can truly allow you to see the physical world in ways that were not possible before."
A deadly myth has been manufactured from poor methods and wishful thinking.
Green algae on a lake
Civil engineer Martin Lebek has a brilliant plan to redress the world’s phosphorus imbalance.
hypermassive neutron star
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where's the line between them?
quantum entanglement qubit ER = EPR
Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would "ER = EPR" mean for our Universe?
brain organoid
Some scientists think brain organoids could develop a form of consciousness. Others say that's science fiction.
astrolabe
The 1,200-year-old "Book of Ingenious Devices" contains designs for futuristic inventions like gas masks, water fountains, and digging machines.
time crystal entangled electron spin
Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.
Not even Einstein immediately knew the power of the equations he gave us.
Jules Verne wrote about gasoline-powered vehicles, weapons of mass destruction, and global warming more than a century ago.
What if we could harvest energy from human heat, sweat, or vibrations?
yeast cell colony humans
Left to their own devices, yeast cells will consume all available resources and poison themselves to death. Is humanity smarter than that?
Ev Fedorenko’s Interesting Brains Project highlights the human brain’s remarkable capacity to adapt, reorganize in the face of early damage.
regions of the universe
The zero-point energy of empty space is not zero. Even with all the physics we know, we have no idea how to calculate what it ought to be.
Take a trip through these master-crafted fantasy societies and ask yourself: Could I actually live there?
3D-printing robots are being used to build a 100-home housing development in the US state of Texas.
planetary nebulae infrared spitzer
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
apple watch
The Apple Watch could soon take the pain out of monitoring blood sugar levels.
