Bose Einstein condensate may reveal supersolid’s secrets

BEC droplets form crystal that may have supersolid-like properties. |SOURCE| Bose Einstein condensates (BECs) have been around for more than 20 years now. One of the best applications of the BEC, it turns out, is as a tool to explore other quantum things, like solids—yes, the properties of solids are determined by quantum mechanics. Among those [...] Read more

Scientists demonstrate simpler way to turn two-layer graphene system into a superconductor

Researchers in Germany have built on previous work by MIT to create a flat band in graphene. |SOURCE| Scientists at the Helmholtz-Zentrum Berlin Fur Materialien Und Energie (HZB) have discovered a new way to enable a two-layer graphene system to conduct electricity like a superconductor. Graphene is an allotrope of carbon, consisting of a sheet of [...] Read more

Astronomers Find Possible Elusive Star Behind Supernova

Hubble archival images were used to uncover doomed star. |SOURCE| The explosive end to a massive star's life is one of the most powerful blasts in the universe. The material expelled by the violent stellar death enriches our galaxy with heavier elements, the building blocks of new stars and even planetary systems. Astronomers have diligently [...] Read more

Chimps have different cultural norms about friendliness, too

Generalizing from one group of chimps to the whole species is a sticky business. |SOURCE| Human cultures have widely varying norms when it comes to friendliness and politeness. Make accidental eye contact with a Londoner on public transport and suffer mutual horror, but go to South Africa and find yourself routinely embraced by complete strangers. [...] Read more
