Why do puddles stop spreading? Simple everyday phenomenon was unexplained by physics—until now
When you spill a bit of water onto a tabletop, the puddle spreads—and then stops, leaving a well-defined area of water with a sharp boundary.
New half-life measurements could improve understanding of heavy elements
Giuseppe Lorusso, of the National Physical Laboratory (NPL), has furthered understanding of the creation of heavy elements as part of an international collaboration to measure the beta-decay half-lives of 110 isotopes. The ...
Training Schrodinger's cat: Controlling the quantum properties of light
The ins and outs of quantum chromodynamics
Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).
Researchers develop ultrahigh-resolution 3D microscopy technique for electric fields
Using a single molecule as a sensor, scientists in Jülich have successfully imaged electric potential fields with unrivalled precision. The ultrahigh-resolution images provide information on the distribution of charges in ...

Revealed: Positronium's behavior in particle billiards
Collision physics can be like a game of billiards. Yet in the microscopic world, the outcome of the game is hard to predict. Fire a particle at a group of other particles, and they may scatter, combine or break apart, according ...
Light-induced magnetic waves in materials engineered at the atomic scale
A new study discovers how the sudden excitation of lattice vibrations in a crystal can trigger a change of the magnetic properties of an atomically-thin layer that lies on its surface.
Research clarifies the physics of water repelling surfaces
Researchers have gained valuable insights into the behaviour of water on strongly hydrophobic (water-repelling) surfaces. Understanding this behaviour should help scientists develop new types of surfaces with applications ...
