Expectations regarding optical behavior that have been widely accepted since Louis Pasteur’s groundbreaking discoveries in 1848 have been overturned by a recent study. Researchers observed optical behaviors associated with chirality in crystalline lithium cobalt selenium oxide (Li₂Co₃(SeO₃)₄), a centrosymmetric crystal that inherently cannot exhibit chirality. “Within the inorganic crystal community, there’s been a strong belief […]

An Italian court has issued a landmark ruling, sentencing 11 executives to prison due to accusations of contaminating groundwater with per- and polyfluorinated alkyl substances (PFAS) originating from the Miteni fluorochemicals facility located in Trissino, Italy. This plant, which has been operating since the 1960s, became a center of environmental concern after probes indicated it […]

**Introduction to CRISPR** CRISPR is an innovative tool that is altering lives and making significant impacts in the medical sector. CRISPR, short for “Clustered Regularly Interspaced Short Palindromic Repeats,” is present in prokaryotes—tiny, single-celled organisms devoid of organelles. These sequences reside in the genomes of prokaryotes, which organize a cell’s DNA in clusters. As a […]

Galileo’s conflicts with the Roman Catholic Church commenced with the “Letter to Castelli” in December 1613. At a dinner in Pisa with Grand Duke Cosimo II de’ Medici, philosopher Cosimo Boscaglia opposed the heliocentric theory, referencing the Bible. Benedetto Castelli, who was present and a student of Galileo, defended the heliocentric perspective. Castelli relayed this […]

Bonaventura Cavalieri (1598–1647) was an innovative mathematician linked with the Galilei-Castelli mathematical school. Originally named Francesco Cavalieri, he took on his father’s name when he joined the Jesuati order at the age of fifteen. The Jesuati, different from the Jesuits, acted as caregivers during the Black Death, recognized for proclaiming Jesus’s name during their prayers. […]

This is the subsequent entry in my series focused on introductory literature regarding the history of mathematics. From one perspective, the series commenced nearly eight years ago when I authored a brief but highly critical review of the book that first introduced me to mathematical history, Eric Temple Bell’s *Men of Mathematics*. Recently, several weeks […]

An injection capable of preventing HIV infection for six months has received approval from the US Food and Drug Administration (FDA). Gilead’s Yeztugo (lenacapavir) is now the longest-acting variant of pre-exposure prophylaxis (PrEP) for adults at risk of sexually acquired HIV. It functions by disrupting HIV’s capacity to create its outer protein shell (capsid) and […]
