Scientists find new solid-state material for thermal regulation

About 90% of the world's energy use involves generation or manipulation of heat, while controlling thermal transport is yet a challenge in many fields, varying from the micro- and nano-scale electronic devices to aeronautics. Materials exhibiting abrupt transition between low and high thermal conductance states are strongly desired for rapidly developing thermal regulation applications.

Foreign-born run greater risk of workplace bullying

The risk of being bullied at work in Sweden is twice as high if you were born outside Sweden. And if you come from a culture that is culturally dissimilar to Sweden's, the risk is even higher. These are the results of a study from Linköping University that was recently published in The International Journal of Human Resource Management.

Galileo will help Lunar Pathfinder navigate around moon

ESA's Lunar Pathfinder mission to the moon will carry an advanced satellite navigation receiver, in order to perform the first ever satnav positioning fix in lunar orbit. This experimental payload marks a preliminary step in an ambitious ESA plan to expand reliable satnav coverage—as well as communication links—to explorers around and ultimately on the moon during this decade.

Researchers confirm accuracy of cosmological data analysis technique using mock data

Astronomers have played a game of guess-the-numbers with cosmological implications. Working from a mock catalog of galaxies prepared by a Japanese team, two American teams correctly guessed the cosmological parameters used to generate the catalog to within 1% accuracy. This gives us confidence that their methods will be able to determine the correct parameters of the real universe when applied to observational data.

Research finds surprising electron interaction in 'magic-angle' graphene

In 2018, physicists showed that something interesting happens when two sheets of the nanomaterial graphene are placed on top of each other. When one layer is rotated to a "magic angle" of around 1.1 degrees with respect to the other, the system becomes a superconductor—meaning it conducts electricity with zero resistance. Even more exciting, there was evidence that it was an unconventional form of superconductivity—a type that can happen at temperatures well above absolute zero, where most superconducting materials function.
