(Phys.org)—Carbon nanotubes (CNTs) are renowned for their thinness, having diameters as small as 3 angstroms (Å), or 0.3 nm. It's generally thought that ultrathin CNTs with diameters smaller than 3 Å are unstable because, ...
It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be engineered under certain ...

In cosmic voids where the density of galaxies is far lower than standard, astronomers have observed weak magnetic fields that may provide a window into the early universe. The fields 10-17-10-10 G in magnitude with large ...
(Phys.org)—A team of researches affiliated with several institutions in the U.K. and Russia has found that chirality in graphene impacts current flow. In their paper published in the journal Nature Physics, the team describes ...
(PhysOrg.com) -- Visiting aliens may be the stuff of legend, but if a scientific team working at the National Institute of Standards and Technology is right, we may be able to find extraterrestrial life even before it leaves ...

When asked to sign their name, comb their hair, or use a pair of scissors, most humans prefer to use one hand over the other. But being left-handed or right-handed—handedness—is a trait found not just in people. Many ...
