Book believed to be bound in human skin
Book believed to be bound in human skin

The binding of books in human skin – anthropodermic bibliopegy – peaked in the 19th century. The practice was most popular among doctors, who had access to cadavers in their profession. It was nonetheless a rare phenomenon even at the peak of its popularity, and fraudulent claims were commonplace; by 2020, the Anthropodermic Book Project had confirmed the existence of 18 books bound in human skin, out of 31 tested cases. The ability to unequivocally identify book bindings as being of human skin dates only to the mid-2010s. The development of peptide mass fingerprinting permitted conclusive testing and became the gold standard method. The first book confirmed as authentic through its use was in 2014; it was a copy of Des destinées de l'ame by the French philosopher Arsène Houssaye. Themes emerge in what purportedly anthropodermic books turn out to be legitimate or illegitimate. Most legitimate anthropodermic books were owned or bound by physicians, and many of them are dedicated to the practice of medicine. (Full list...)

The Canadian province of Alberta has 438 species of birds. The northern part of the province is largely boreal forest, leading into the Great Plains in the south-east. The south-west portion of the province is generally temperate coniferous forest, bordered by the Rocky Mountains. These different ecosystems, along with the border formed by the Rocky Mountains, contribute to the diversity of birds in the province. Notably, several "eastern" and "western" pairs can be seen in Alberta, such as the eastern bluebird and western bluebird. Of the 438 species, 125 are accidentals, eight were introduced to Alberta, one species is extinct, and another is possibly extinct. (Full list...)

"Pachelbel's Howitzer", a piece that reworks the Canon into multiple genres for piano

Johann Pachelbel's Canon in D major has been credited with inspiring a significant number of pop songs since the 1960s. After the mid-Baroque era piece was revived from obscurity in the 1960s, its chord progression, bassline, and melodic structure were reproduced in a number of contemporary pop songs, a phenomenon attributed to the memorability and simplicity of the work as well as renewed interest in it. While Pachelbel's Canon itself is not a staple of pop music, it shares common roots with other, more significant chord progressions that lay the foundations of modern pop music. Its perceived ubiquity is itself an object of cultural discussion. (Full list...)

The Marvin Miller Man of the Year Award is given annually to a Major League Baseball (MLB) player "whose on-field performance and contributions to his community inspire others to higher levels of achievement." The award was created by the Major League Baseball Players Association (MLBPA) and was presented to the inaugural winner – Mark McGwire – in 1997 as the "Man of the Year Award". Three years later, it was renamed in honor of Marvin Miller, the first executive director of the MLBPA. In order to determine the winner, each MLB team nominates one of their players, who is selected by their teammates to appear on the ballot. An online vote is conducted among baseball fans in order to reduce the number of candidates to six. MLB players then choose the award winner from among the six finalists. John Smoltz, Jim Thome, Michael Young, and Curtis Granderson are the only players to win the Marvin Miller Man of the Year Award on multiple occasions. (Full list...)

Seventeen people have held the office of President and Chancellor of New York University (NYU), a private research university in New York City. The president of New York University is its chief executive officer and is elected by the university's board of trustees, of which the president is a member ex officio. From NYU's foundation by Albert Gallatin in 1831 until 1956, the head of NYU was the chancellor. That year, the office became known as "president and chancellor", or "president" for short. The president recommends persons to fill senior offices, including the provost, executive vice president, general counsel, and deans, who are then appointed by the board. The president also presides over the university senate and confers all degrees, with the board's authorization and upon certification of a student by the faculty. The incumbent president, Linda G. Mills (pictured), assumed office on July 1, 2023 and became NYU's first female president. (Full list...)
