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 ...

Brighter comb lasers on a chip mean new applications

Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications. The advance ...

Southern US swelters in brutal heat wave

A dangerous and prolonged heat wave blanketed large parts of the southern United States on Tuesday, buckling highways and forcing people to shelter indoors in what scientists called a climate-change supercharged event.
