An electric field can displace the cloud of electrons surrounding each atom of a solid. In an effect known as polarization, the cloud centers move away slightly from the positively charged nuclei, which radically changes the optical properties of the solid.

Gene therapy can only be effective if delivered by a stable complex molecule.

(PhysOrg.com) -- Ferromagnetic materials are key ingredients in vast arrays of technologies including wind turbines, computer hard-disks, credit card readers, and many more. Typically these magnets operate in moderate environments. But exposing a magnetic material to high heat or compressive stress usually destroys its magnetism because high temperatures and high compression induce agitation and mobility of unpaired electrons ("atomic compass"), destroying the correlated arrangement of atomic compasses across the solid needed to generate, or detect, magnetic fields

Institute for Solid State Physics, the University of Tokyo and RIKEN announced that researchers from both institutes succeeded in the magnetic control of anomalous Hall effect (AHE) induced by spin chirality.

The 8.9-magnitude earthquake in Japan shortened Earth's day by 1.8 millionths of a second. While this might sound striking, perhaps even scary, don't panic: Earth is shifting slightly all the time, owing mostly to atmospheric and ocean currents. The 8.9-magnitude earthquake in Japan on March 11 shortened Earth's day by 1.8 millionths of a second, according to NASA scientists
