Hexagonal copper disk lattice unleashes spin wave control

A collaborative group of researchers has potentially developed a means of controlling spin waves by creating a hexagonal pattern of copper disks on a magnetic insulator. The breakthrough is expected to lead to greater efficiency ...

Hubble finds telltale fireball after gamma ray burst

(Phys.org) —NASA's Hubble Space Telescope has provided the strongest evidence yet that short-duration gamma-ray bursts are triggered by the merger of two small, super-dense stellar objects, such as a pair of neutron stars ...

Disappearing homing pigeon mystery solved

Homing pigeons are usually remarkably efficient navigators, however, on rare occasions, things go drastically wrong. So, when Jon Hagstrum of the US Geological Survey read in his local newspaper about two races when pigeons ...

Earliest spiral galaxy ever seen: a shocking discovery

(Phys.org) -- Astronomers have witnessed for the first time a spiral galaxy in the early universe, billions of years before many other spiral galaxies formed. In findings reported July 19 in the journal Nature, the astronomers ...

Cattle respond to magnetic fields from power lines

(AP) -- High-voltage power lines mess with animal magnetism. Researchers, who reported last year that most cows and deer tend to orient themselves in a north-south alignment, have now found that power lines can disorient ...
