Raising the prospects for quantum levitation

More than half-a-century ago, the Dutch theoretical physicist Hendrik Casimir calculated that two mirrors placed facing each other in a vacuum would attract. The mysterious force arises from the energy of virtual particles ...

Cosmology in a Petri dish

Scientists have found that micron-size particles which are trapped at fluid interfaces exhibit a collective dynamic that is subject to seemingly unrelated governing laws. These laws show a smooth transitioning ...

How to build doughnuts with Lego blocks

Scientists have uncovered how nature minimises energy costs in rings of liquids with an internal nanostructure made of two chemically discordant polymers joined with strong bonds, or di-blocks, deposited on ...

Tangling the microscopic ladder

If a ladder had more than one rung at each step, it would look awkward and would be a bit dangerous to climb. Ladders in the microscopic world were thought to be similar in structure, having only one particle, ...

How not to blow up a molecule

High-charge-state ions in a molecule cause strong Coulomb forces, repulsive forces that try to blow its atoms apart. But the research team's crucial finding was that a way to produce only lower charge states ...
