It’s impossible to go throughout this day, September 11th, without acknowledging the extent of the impact that the terrorist attacks had on America and its citizens. In the wake of the 13th anniversary of the attacks, those of us at STEM Works wanted to show how STEM has been utilized throughout the aftermath processes of identifying victims, surveying the damage and rebuilding Ground Zero.
Identifying Victims with Forensics
After the initial attacks, at least 1,115 out of at least 2,753 victims remained unidentifiable, even after scientists analyzed DNA samples provided by the families of those with missing loved ones who never came home or were never identified. Despite painstaking work over the years from scientists in New York to match bone fragments to an actual identity, restraints in technology left many victims unidentified. However, recent technological advances in DNA testing and forensic identification have given both scientists and families a renewed sense of hope as these DNA tests yield results that would have been impossible 10 years ago. Scientists previously faced the challenge of identifying victims using bone slivers that contained DNA that had been damaged by fire, sunlight, bacteria, or jet fuel. Using the new technology, scientists are able to go back to the same bone fragment and attempt to extract the damaged DNA for testing. Read more here.
Engineering a Better World Trade Center
Considered a testament to the perseverance of the American spirit, the five-year re-construction projects of the new World Trade Center and National September 11 Memorial and Museum are shown in this behind-the-scenes documentary, made by PBS, in cooperation with NOVA, to demonstrate the many various challenges and high expectations that engineers and architects faced to build a stronger, taller, and safer World Trade Center. Watch Engineering Ground Zero.
Engineers played a huge role in both clean up and re-building. PBS has also created a number of valuable resources to teach the public about how engineers assisted with rescuing victims, surveying the damage, and preventing unstable structures from falling and potentially injuring more people. Check out these resources here at Engineering the Clean-Up.
