Restraint improves dielectric performance, lifespan

Just as a corset improves the appearance of its wearer by keeping everything tightly together, rigidly constraining insulating materials in electrical components can increase their energy density and decrease their rates ...

How plants sense touch, gravity and other physical forces

(PhysOrg.com) -- At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation of the membrane. ...

Rare earths 'replaced' by silicon chip

Rare earths are an expensive and necessary component of strong permanent magnets. However, their use for this purpose can be optimised and thereby reduced. This has been demonstrated in computer simulations by a Special Research ...

NASA study of Haiti quake yields surprising results

(PhysOrg.com) -- The magnitude 7.0 earthquake that caused more than 200,000 casualties and devastated Haiti's economy in January resulted not from the Enriquillo fault, as previously believed, but from slip on multiple faults ...

Chemists grow crystals with a twist -- and untwist

(PhysOrg.com) -- Chemists from New York University and Russia's St. Petersburg State University have created crystals that can twist and untwist, pointing to a much more varied process of crystal growth than previously thought. ...
