WhenAmelia Earhartdisappeared essay to compass the humanity , charge card were so rarified their thriftlessness was a minor problem , even in major cities . In the central Pacific , where Earhart was last see , the idea of formative befoulment probably seemed impossible . Yet reanalysis of one of the possible clue to Earhart ’s last emplacement has had a spinoff in the quest to tackle a problem now pass themost remoteparts of the humankind .
Fifty years after Earhart and sailing master Fred Noonan vanished , a metal control panel was found at Nikumaroro , known in Earhart ’s fourth dimension as Gardner Island , along with other item that might once have been part of their sheet . In usingneutron radiographyto study the panel , scientist may finally break up one of aviation ’s biggest mysteries .
The panel has been a puzzle since it was find in 1991 as part ofa searchby The International Group for Historic Aircraft Recovery . It carries stud pipeline that resemble those see in photos of Earhart ’s Lockheed Electra , but the match is n’t unadulterated . Perhaps it came from another plane , although such a remote island was not claver often , or maybe scathe to the Electra draw a piece - up chore , and the renewal was all we have been able-bodied to get hold .
Some people believe this panel is the key to unravelling the mystery of what happened to Amelia Earhart. Neutron radiography images are overlaid on the image. Image credit: Kenan Ünlü
When Daniel Beck of Penn State Universitysaw a documentaryon the search for Earhart , he thought the University ’s Breazeale Reactor ’s neutron ray of light might be what was needed to determine the panel ’s origins .
Neutron radiography relies on the funny fact that neutrons interact with some element , but are unaffected by others . Unlike with tenner - Rays , this is is n’t determined by tightness . " We thought it was a good fit – we were fairly confident we ’d be capable to see the remnants of marks fatigue away or paint particles , " Beck said in astatement . " The first images were really exciting , but we knew we take to do considerably to confirm what we thought we attend . We were already in the process of upgrade the neutron imaging facility , so the board provided the perfect sample distribution to optimise our neutron radiography potentiality . "
The upgrade grant the team to see letters and numbers scratch on the panel neither they nor others who had studied it before had detected . " We found what front like stamp or paint marks that could be from the original manufacturer , " state Penn State ’s Professor Kenan Ünlü . We do n’t know what they think , but they are the first new info from this panel that has been examined by various expert with different scientific technique for over 30 years . "

The panel proved such an ideal test subject it allowed the squad to prepare their reactor ’s predisposition , ameliorate its capacity to handle its next challenge ; trace microplastics .
doctorial pupil Alibek Kenges applied the neutron radio beam to sandpaper samples . “ The ensue image does n’t show the sand at all , but the microplastics , from a millimetre to a few millimeters in size , illumine up like Christmas light , ” Kenges said .
The find that microplastics are now abundant in the surround is uncheerful , buthardly a divine revelation . Where Kenges ’ work may prove groundbreaking is in studying where microplastics are n’t , specifically their absence from pee that has return through filter .
In the quest to find screens that will remove microplastics from effluent , an effective and authentic means to determine the presence of credit card particles in filter out weewee is of the essence . Otherwise , we have no way of jazz which filter make for best .
Preliminary result of the microplastics workwere presentedat the International Atomic Energy Agency ’s late group discussion onApplications of Radiation Science and Technology . The squad know , however , their techniques still involve refinement . The progress made in the quest to solve the Earhart mystery has take the team part right smart towards their goal . Hopefully , unlike Earhart , they can make it all the way of life .
