Three Cuts Inside Your Eye - Vitrectomy is a delicate eye surgery that uses microscopic instruments to remove the vitreous gel, allowing surgeons to treat retinal problems, clear internal bleeding, and help preserve or restore vision.

Chinese scientists have found genetic evidence that early millet-farming populations in northern China originated locally rather than emerging from a major influx of migrant agricultural groups, according to research published in the journal Science Advances. The research analyzed genome-wide data from seven ancient individuals at the Donghulin site in Beijing and the Dengcaogouliang and Sitai sites in Zhangjiakou, North China's Hebei Province, combined with carbon-14 dating and stable isotope evidence. It covers a period from about 11,000 to 7,300 years ago. Combining ancient genomics, archaeological remains and dietary evidence, it has revealed the genetic continuity and local origin of millet-related populations in the region.
