Head louse

The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans that causes pediculosis capitis. Head lice are wingless insects spending their entire life on the human scalp and feeding exclusively on human blood.Humans are the only known hosts of this specific parasite, while chimpanzees host a closely related species, Pediculus schaeffi. Other species of lice infest most orders of mammals and all orders of birds, as well as other parts of the human body.

Lice differ from other hematophagic ectoparasites such as fleas in spending their entire life cycle on a host. Head lice cannot fly, and their short stumpy legs render them incapable of jumping, or even walking efficiently on flat surfaces.

The non-disease-carrying head louse differs from the related disease-carrying body louse (Pediculus humanus humanus) in preferring to attach eggs to scalp hair rather than to clothing. The two subspecies are morphologically almost identical but do not normally interbreed, although they will do so in laboratory conditions. From genetic studies, they are thought to have diverged as subspecies about 30,000–110,000 years ago, when many humans began to wear a significant amount of clothing. A much more distantly related species of hair-clinging louse, the pubic or crab louse (Pthirus pubis), also infests humans. It is visually different from the other two species and is much closer in appearance to the lice which infest other primates. Lice infestation of any part of the body is known as pediculosis.

Stay (Bernard Butler song)

"Stay" is the debut single from Bernard Butler released in January 1998. It was taken from the album People Move On and charted at number 12 on the UK Singles Chart.

Background

The song begins with a gentle acoustic guitar, which leads into Butler's vocals. Drums, electric guitar, keyboards and backing vocals all get introduced gradually, before coming together in one last climax and quiet coda. Butler has said that "Stay" is not a love song but a song about change. "The process of change is hard but you've got to do it. It's about when you know you've got to do something but there's an element of risk. It's about when I first went to France to record. A lot of the lyrics come from a conversation with Elisa, my wife. I wrote them on the train over to France."

The music video for the title song was directed by David Mould, whose directing credits include Suede's "Trash", the first single released after Butler's departure. B-side "Hotel Splendide" features lead vocals from Edwyn Collins.

Can't Be Tamed

Can't Be Tamed is the third studio album by American singer Miley Cyrus. It was released on June 18, 2010, by Hollywood Records; it would become her final album with the label after signing with RCA Records in 2013. Cyrus wrote the project in 2009, while travelling internationally for her Wonder World Tour, and recorded it in 2010. Described by Cyrus as a "good [record] to blast in your car", Can't Be Tamed represents a musical departure from her earlier work, which she had grown to feel uninspired by. As executive producers, Tish Cyrus and Jason Morey enlisted partners including Devrim Karaoglu, Marek Pompetzki, Rock Mafia, and John Shanks to achieve Cyrus' desired new sound. Their efforts resulted in a primarily dance-pop record, which Cyrus' record label acknowledged differed from the original plans for the project. Its lyrical themes revolve largely around breaking free of constraints and expectations, which are largely mentioned in the context of romantic relationships.
