Did Michelangelo paint a young adult woman with breast cancer in "The Flood" (Sistine Chapel, Rome)?

The Flood is the first pictorial scene that Michelangelo Buonarroti painted on the ceiling of the Sistine Chapel in the Vatican. On the right side of the fresco a woman with abnormal breast morphology is presented and the nature of her disease is considered using the Guidelines for Iconodiagnosis. A team of experts covering art history, art expertise, medicine, genetics, and pathology undertook the process and concluded that the pathology shown is probably breast cancer, most likely linked to the symbolic significance of an inevitable death as expressed in the Book of Genesis.

Chemically Stable Diazo Peptides as Selective Probes of Cysteine Proteases in Living Cells.

Diazo peptides have been described earlier, however, due to their high reactivity have not been broadly used until today. Here, we report the preparation, properties, and applications of chemically stable internal diazo peptides. Peptidyl phosphoranylidene-esters and amides were found to react with triflyl azide primarily to novel 3,4-disubstituted triazolyl-peptides.

Assassination of Elisabeth, Empress of Austria, Queen of Hungary, on 10 September 1898: further additions and minor annotations.

Very recently, a comprehensive re-evaluation of the medical facts and observations surrounding the death of Empress Elisabeth "Sisi" of Austria (1837-1898) was published.
