At present-day, more than ten percent of all global marriages occur among first or second cousins. While cousin-marriages are common practice in some societies, unions between close relatives are discouraged in others. In a new study, researchers inves…

Light does the twist for quantum computing

Scientists have generated circularly polarized light and controlled its direction without using clunky magnets or very low temperatures. The findings show promise for the development of materials and device methods that can be used in optical quantum i…
