The Conservation Intelligence Initiative develops advanced technologies that empower protected area partners by enabling data-driven conservation. To preserve the organs from decay and make the scans as sharp as possible, Tafforeau knew that they would need to be treated with several rounds of ethanol-water solutions. HiP-CT scans can zoom in from a whole-organ scan to provide a cellular view of regions of interest. "We'll need 100 years to go through all [the data] and really .
