The efforts to identify the remains of Nicolaus Copernicus (1473-1543), found under the cathedral in Frombork, was made in a collaborative project between Swedish and Polish scientists in a team consisting of archaeologists, anthropologists and geneticists. The results is published this week in the prestigious journal PNAS (Proceedings of the National Academy of Sciences).
At Uppsala University a DNA analysis was performed of shed hairs found in a book owned by Copernicus for decades, and now kept in Museum Gustavianum at Uppsala University.
"The analysis of several hairs resulted in interpretable profiles for four of the hairs. Of these, two of the hairs have the same profile as the putative remains of Copernicus", says Marie Allen, researcher at Uppsala University.
The Uppsala researchers also made tests of a tooth as well as bone tissue from the putative remains of Copernicus. Results from the analysis of the remains from the Institute of Forensic Research in Krakow and the Museum and institute of zoology in Warsaw and the Uppsala laboratory were identical.
"Although these results points towards the materials being from the same individual, there is a probability of random match", says Marie Allen.
The DNA material in this case was limited and also degraded. Therefore, a so called mitochondrial DNA test was performed, which yields a relatively low evidentiary value. This test is commonly used in criminal investigations, but as circumstantial evidence to strengthen the case.
"The DNA results should be looked at and evaluated in the light of, and together with the information from other disciplines as the archaeological, anthropological and facial reconstruction data", says Marie Allen.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
