Scientific Research & Papers
This page documents the scientific and historical literature behind the events in this record. Papers are organized by evidence tier — peer-reviewed journal articles first, then expert analyses and primary historical documents.
For each source: the researcher’s credentials, the journal, the core finding, and a screenshot of the key passage from the paper itself.
To add screenshots: take a screenshot of the relevant passage, save it to public/images/papers/, and swap the file path into the src prop of the PaperImage component in the MDX source. The placeholder shows exactly which passage to capture.
A note on who these researchers were
Section titled “A note on who these researchers were”Tier 1 — Peer-reviewed scientific papers
Section titled “Tier 1 — Peer-reviewed scientific papers”Rogers, R.N. (2005)
Section titled “Rogers, R.N. (2005)”“Studies on the radiocarbon sample from the Shroud of Turin”
Thermochimica Acta, 425(1–2), pp. 189–194
DOI: 10.1016/j.tca.2004.09.029
Researcher: Raymond Rogers — physical chemist, Los Alamos National Laboratory; Fellow of the American Chemical Society; member of the original 1978 STURP investigation.
Background: The 1988 radiocarbon dating produced a medieval date. Rogers was skeptical of challenges to this. He obtained threads from the sampled corner and ran his own chemical analysis.
Finding: The sampled threads contained vanillin — a lignin decomposition product that decays at a known rate with age. The main body of the Shroud contains no vanillin. This indicates the sampled corner is chemically younger than the rest of the cloth — consistent with a medieval patch or repair. Rogers concluded the 1988 sample was not representative of the original linen.
Abstract — note Rogers' institutional affiliation (Los Alamos) and journal (Thermochimica Acta, Elsevier peer-reviewed)

Vanillin test results comparing the 1988 sampled threads against main Shroud linen — the chemical basis for Rogers' conclusion that the samples came from different cloth
Same paper — screenshot Table 1 (vanillin / lignin test results)
Rogers' written conclusion: the radiocarbon sample was not representative of the original cloth. Published after his own analysis changed his prior skeptical position.

Heller, J.H. & Adler, A.D. (1981)
Section titled “Heller, J.H. & Adler, A.D. (1981)”“A chemical investigation of the Shroud of Turin” Canadian Society of Forensic Science Journal, 14(3), pp. 81–103
Researchers: John Heller (Yale-educated biophysicist, New England Institute) and Alan Adler (professor of chemistry, Western Connecticut State University; specialist in porphyrin chemistry — the chemistry of blood pigments).
Finding: The Shroud bears real human blood. The blood and the image are chemically distinct — ruling out the theory that blood was painted over an existing image. The image itself is not formed by any known chemical agent.
Journal header and abstract — published in a forensic science journal, not a religious publication. Note the authors' institutional affiliations.

Jumper, E.J., Adler, A.D., Jackson, J.P., Pellicori, S.F., Heller, J.H., & Druzik, J.R. (1984)
Section titled “Jumper, E.J., Adler, A.D., Jackson, J.P., Pellicori, S.F., Heller, J.H., & Druzik, J.R. (1984)”“A comprehensive examination of the various stains and images on the Shroud of Turin” ACS Advances in Chemistry Series, 205, pp. 447–476
Researchers: The core STURP analytical team, published in a peer-reviewed ACS (American Chemical Society) volume.
Finding: The image is not formed by any paint, pigment, powder, or identifiable chemical substance. The coloring is confined to the outermost fibrils of the linen threads — a depth achievable by no known artistic technique. Mechanism of formation: unknown.
Author list and institutional affiliations — Los Alamos National Laboratory, Jet Propulsion Laboratory, and others. Published in an American Chemical Society peer-reviewed volume.

Linoli, O. (1971)
Section titled “Linoli, O. (1971)”“Ricerche istologiche, immunologiche e biochimiche sulla carne e sul sangue del miracolo eucaristico di Lanciano” Quaderni Sclavo di Diagnostica Clinica e di Laboratorio, 7(3), pp. 661–674
Researcher: Professor Odoardo Linoli — Professor of Anatomy and Histological Chemistry, University of Siena; Head of the Laboratory of Pathological Anatomy, Hospital of Arezzo.
Finding: The Lanciano tissue is human cardiac muscle (myocardium, left ventricle). The blood is human, type AB, with protein fractionation consistent with fresh healthy blood. No preservatives found.
Title page and author credentials — Professor of Anatomy and Histological Chemistry, University of Siena
This is a 1971 Italian medical journal. Contact the Diocese of Chieti-Vasto (Lanciano shrine) for a copy of the original paper. Some Catholic research archives hold a translated version. Joan Carroll Cruz's 'Eucharistic Miracles' (TAN Books, 1987) contains translated excerpts.

Researcher: Dr. Javier Torroella Bueno — ophthalmologist, Mexican Academy of Ophthalmology.
Finding: The reflections in both eyes of the Guadalupe image follow the Purkinje-Sanson triple reflection pattern — the optical behavior of a living human eye, not a painted representation.

Callahan, P.S. & Smith, J.B. (1981)
Section titled “Callahan, P.S. & Smith, J.B. (1981)”Photographic Exhibition of an Infrared Photograph of the Tilma of Juan Diego CARA Studies on Popular Devotion, Vol. II, No. 4. Washington, D.C.
Researcher: Dr. Philip Serna Callahan — entomologist and biophysicist, University of Florida; Research Professor, USDA Agricultural Research Service; specialist in infrared optics.
Finding: No underdrawing. No sizing. No brush strokes. The image colors show no UV fluorescence — anomalous with every tested paint and dye. Image appears to float above the cloth surface.
Callahan's credentials and institutional affiliation (University of Florida / USDA) — a professional research scientist, not a religious commentator
CARA (Center for Applied Research in the Apostolate) at Georgetown University holds this monograph. Request a copy through their library. Some university libraries with Latin American studies collections hold it.

Zugibe, F. (1999) — Buenos Aires tissue analysis
Section titled “Zugibe, F. (1999) — Buenos Aires tissue analysis”Expert report on file with the Archdiocese of Buenos Aires
Researcher: Dr. Frederick Zugibe — Chief Medical Examiner, Rockland County, NY; Adjunct Professor of Pathology, Columbia University. Blind analysis — Zugibe was not told the origin of the sample.
Finding: Human cardiac muscle (left ventricle), acute inflammation, white blood cells visibly motile. Blood type AB. No biological explanation for living cells in a three-year-old stored sample.
Zugibe's written findings identifying the tissue as myocardium from the left ventricle, with active (motile) white blood cells — produced before he was told the sample came from a communion wafer
Contact the Archdiocese of Buenos Aires. Dr. Ricardo Castañón Gómez (who coordinated the investigation) has published documentation in 'A Scientist Researches Mary' (2002). Some Catholic research organizations hold copies of the analysis report.
Tier 3 — Academic books by secular researchers
Section titled “Tier 3 — Academic books by secular researchers”Duffin, J. (2009)
Section titled “Duffin, J. (2009)”Medical Miracles: Doctors, Saints, and Healing in the Modern World Oxford University Press. ISBN: 978-0195313727.
Author: Jacalyn Duffin — Hannah Professor of the History of Medicine, Queen’s University, Ontario; practicing physician (hematologist). Self-described non-Catholic. Came to the subject through a routine court case — she provided a medical expert opinion on a woman’s recovery from leukemia, concluded it was inexplicable, and later learned her report had been used in a Vatican canonization cause.
Book cover and publisher (Oxford University Press) — a secular academic press. Duffin's professional biography makes clear this is not a work of religious advocacy.
Available from Oxford University Press, Amazon, or any academic library. Screenshot the back cover or author biography, and the introduction where Duffin describes how she came to the subject.
Duffin describes being asked by a Canadian court to give a medical opinion on an inexplicable recovery — her entry point into Vatican miracle documentation, with no religious motivation
Same book — Introduction, pages 1–10 roughly. Screenshot the passage where she describes the court case.

Avelino de Almeida — editor of Portugal’s largest secular, anticlerical daily — traveled to Fatima to write a dismissive article. His front-page account the following morning reported what he witnessed.
The front page of O Século two days after the Miracle of the Sun — a secular anticlerical newspaper reporting the event against the editor's prior intentions
