Study could lead to production of more efficient optoelectronic devices
Diodes are widely used electronic devices that act as one-way switches for current. A well-known example is the LED (light-emitting diode), but there is a special class of diodes designed to make use of the phenomenon known as "quantum tunneling". Ca.....»»
Study suggests heavy snowfall and rain may contribute to some earthquakes
When scientists look for an earthquake's cause, their search often starts underground. As centuries of seismic studies have made clear, it's the collision of tectonic plates and the movement of subsurface faults and fissures that primarily trigger a.....»»
Genetic study finds early summer fishing can have an evolutionary impact, resulting in smaller salmon
Atlantic salmon are caught by fisheries when the fish are migrating to spawn. A new study led by the University of Helsinki explored how salmon caught at different times during their spawning migration differ from each other genetically. The study on.....»»
