A new way to control light could boost future wireless tech

Researchers have built a new optical device that can produce two different vortex-shaped forms of light, one electric and one magnetic. These structured light patterns, known as skyrmions, are exceptionally stable and remain intact even when exposed to interference. That resilience makes them attractive candidates for encoding information in future…

A relatively new technology, known as transcranial focused ultrasound, may offer a powerful way to investigate this mystery more directly. Although…

Melting Antarctic ice may weaken a major carbon sink

A new study published in Nature Geoscience shows that changes in the West Antarctic Ice Sheet (WAIS) closely followed shifts in marine algae growth in the Southern Ocean during past glacial cycles. However, the relationship unfolded in a surprising way that challenges long-standing assumptions. At the center of the discovery…
