Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

Multiferroic materials, in which electric and magnetic properties are combined in promising ways, will be the heart of new ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

And it's not because of the hole in the ozone layer. The main reason for our high UV is because, during the Southern Hemisphere summer, our planet is closer to the source of the radiation ...

A landmark study reporting the discovery of Australopithecus africanus one century ago put the African continent at the centre of the story of humanity. Overcrowding can lead to disaster, and yet ...

Direct current does not change directions-- the electron flow is always from the negative pole to the positive pole -- although as we mentioned before, the electrons themselves don't really "move," it ...

A minimalist game about digging a hole in the garden of a newly purchased house. Collect resources, sell them, upgrade your equipment and discover a mysterious secret. Costs you only one coffee!
