Scientists propose 3D graphene-like 'hyper-honeycomb' structures
(Phys.org)—Scientists have proposed a new family of structures that are three-dimensional (3D) variations of graphene, the simplest example of which is called a "hyper-honeycomb." If the proposed structures can be experimentally ...
Weyl points: Long-sought phenomenon finally detected
Part of a 1929 prediction by physicist Hermann Weyl—of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point,"—has finally been confirmed by direct observation for the ...

No need for sophisticated hunting techniques: Equatorial bats live the easy life
Most of the world's bats use extremely sophisticated hunting techniques, but not bats around the equator. They use pretty much the same less sophisticated hunting techniques as their ancestors did millions of years ago. They ...

Still a filament arrow?
On May 28, 2015 (above left), the sun, as seen by NASA's Solar Dynamics Observatory, showed a pair of filaments in the form of an arrow. The filaments appeared to remain stable as they rotated around to the far side of the ...

Mathematicians formulate equations, bend light and figure out how to hide things
The idea of cloaking and rendering something invisible hit the small screen in 1966 when a Romulan Bird of Prey made an unseen, surprise attack on the Starship Enterprise on Star Trek. Not only did it make for a good storyline, ...
