What’s The Strongest Knot, And How Do We Know?
In 333 BCE, legend says, Alexander the Great entered the city of Gordion, in Phrygia, now Turkey. The once mighty power had by that point been reduced to a mere province of the Persian Empire, and all it had left of its proud history was an old wagon, tied to a post in the town […]
Colossal’s “Woolly Mouse” Advances 2028 Mammoth De-Extinction Goal, Antarctica’s Ozone Hole Is Recovering, And Much More This Week
This week, in a world first, 3D-printed tissue has restored penis capabilities in pigs and rabbits, we ask why so few international organizations have responded to Trump and Musk’s attack on science, and humans may have been producing tools made from bones for more than 1 million years longer than we previously thought. Finally, we […]

Light Quasiparticles Have Been Turned Into A Supersolid For The First Time
In condensed matter physics, things can get pretty weird. When temperatures get close to absolute zero, it is possible to put matter in a state called supersolid, a crystal that can flow without losing energy. Under the right conditions, it is also possible to couple light with excited states of matter, creating quasiparticles – interactions […]
