Do dark matter and dark energy exist?

Researchers have hypothesized that the universe contains "dark matter." They have also posited the existence of "dark energy." These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion ...

Researchers discover switching function in molecular wire

The increasing miniaturisation in electronics will result in components which consist of only a few molecules, or even just one molecule. Tiny wires are required to connect these to an electrical circuit at the nano level. ...

Nanomaterial risk profiling puts safety first

With uncertainty around the risks of nanomaterials hampering the EU's innovative potential, researchers are working on a safety concept to better monitor this emerging technology.

Study challenges validity of the psychological "Grit Scale"

The Grit Scale questionnaire has gained popularity over the past decade, not only in research but also in practical psychology and in employee selection. The questionnaire is used to measure grit—a personality trait combining ...

Small scale energy harvesters show large scale impact

The production of nano-scale devices has drastically increased with the rise in technological applications, yet a major drawback to the functionality of nano-sized systems is the need for an equally small energy resource.

Bringing atomic mapping to the mainstream

Mapping the internal atomic structure of small particles just got easier thanks to a new computer algorithm and graphical user interface (GUI) developed by scientists at and Lawrence Berkeley National Laboratory (Berkeley ...
