Using the world's most advanced radio telescopes, astronomers have discovered a spinning dead star so rare, strange and ...

A self-decoupling method is proposed for two hexagonal patch antennas separated by distance 0.004λ0 at 2.54 GHz with the feature of pattern reshaping. The technique blocks fringing field coupling with ...

When the researchers rotated the star patterns, the moths turned accordingly. When the star map was scrambled, and the Milky Way and constellation patterns were lost, the moths became disoriented.
