New Scientist : Trying to find remains that have been buried, even animals as large as an elephant or mass graves, is not an easy task. It is made even more difficult when investigators only appear on the scene months or years after such events occur.One research tool that could potentially help is hyperspectral imaging . This multi-wavelength detector looks for variations in the intensity of light at various wavelengths reflected by vegetation on the ground. The precise pattern of intensities has been found to reflect changes caused by nutrients released into the soil as bodies decompose.
