In the study of ways to determine the position of and manipulate magnetic nanoparticles – a capability that would benefit a wide range of applications – there's good news and bad: While a magnetic gradient force field ...
(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...
For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality.

Quincke rotation is defined as the spontaneous steady rotation of a dielectric particle immersed in a dielectric solvent under a steady and uniform electric field. Electro-hydrodynamically driven active particles based on ...
A team of researchers working at Stanford University has used time dilation in an atomic fountain to measure the curvature of space-time. In their study, reported in the journal Science, the group used the fountain as an ...
A new study illuminates surprising choreography among spinning atoms. In a paper appearing in the journal Nature, researchers from MIT and Harvard University reveal how magnetic forces at the quantum, atomic scale affect ...
