Physicists Discover the Most Complex Forms of Ice Yet
Scientists keep detecting new forms of ice. According to simulations, there could be many more left to find.
Quantum ‘Jamming’ Explores the Truly Fundamental Principles of Nature
Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things.
Experiments Ring the ‘Death Knell’ for Sterile Neutrinos
Decades of weird experimental results appeared to support the existence of the sterile neutrino, a hypothetical particle that would solve multiple mysteries. But recent experiments have killed hope of finding these phantoms, leaving physicists to wonder what might explain their anomalies.
A Through-The-Lens Look at the World’s Particle Physics Labs
The winning entries in the 2025 Global Physics Photowalk contest showcase the beauty of toil and discovery.
In Expanding de Sitter Space, Quantum Mechanics Gets Even More Elusive
The basic shape that best describes our expanding universe is also the hardest shape for physicists to understand.
Are Strings Still Our Best Hope for a Theory of Everything?
Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the world.
Quantum Cryptography Pioneers Win Turing Award
Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.
Why Do Humanoid Robots Still Struggle With the Small Stuff?
The last decade has seen vast improvements in humanoid robots, but graduating to widespread use might require going back to the fundamentals.
Where Some See Strings, She Sees a Space-Time Made of Fractals
Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.
