But in a New York lab, a team is still avidly working to identify the remains, with technological progress on its side. Cut and ground to a fine dust, the remains are then mixed with two chemical products that can expose and then extract DNA. The 22,000 pieces of human remains found at the site since the attacks have all been tested - some 10 or 15 times already. The lab only dedicates part of its work to 9/11 identification and handles other deaths and disappearances. Teams from all over the world - from Argentina to South Africa - now come to New York to learn from the team.
