Brazilian twins who were joined at the head have been successfully separated with the help of virtual reality.
Three-year-olds Bernardo and Arthur Lima underwent surgeries in Rio de Janeiro, with direction from Great Ormond Street Hospital in London.
The teams spent months trialling techniques using virtual reality projections of the twins, based on CT and MRI scans.
It was described by surgeon Noor ul Owase Jeelani as "space-age stuff."
It was one of the most complex separation processes ever completed, according to the charity which funded it - Gemini Untwined - which Mr Jeelani founded in 2018.
He said that, for the first time, surgeons in separate countries wore headsets and operated in the same "virtual reality room" together.
The twins had seven surgeries, involving more than 27 hours of operating time in the final operation alone, and almost 100 medical staff.
As with all conjoined twins after separation, the boys' blood pressures and heart rates were "through the roof" - until they were reunited four days later and touched hands.
The twins are recovering well in hospital, and will be supported with six months of rehabilitation.
