Not all "vampires" reside in Transylvania; some infest underwater pens of farmed salmon. Tiny parasites called sea lice make life miserable for both farmed and wild fish, weakening adults and killing juveniles.

These bloodsuckers pose a dual threat: the lice themselves harm fish, and the pesticides used to control them can be toxic to other marine life. Their prevalence signals a critical need for improved practices in certain salmon farms.

Racism denies humanity, sexism demeans, and their intersection limits true freedom. Frances Cudjoe-Waters, a Black woman and Harvard Law alumna, realized the exhaustion of politely presenting her pain to predominantly white audiences. She decided to abandon polite conversation and speak her truth, declaring, "I Ain't Sorry." She never expected to witness the reemergence of civil rights issues like Charlottesville and repeated acquittals for killings of Black individuals, reminiscent of the 1960s. While seeking to facilitate discussions, she recognized the toll of maintaining dispassionate intellectualism. Her family was featured in the Dallas Morning News.
