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.

Kronos Quartet discography

The discography of the Kronos Quartet includes 43 studio albums, two compilations, five soundtracks, and 29 contributions to other artists' records. The Kronos Quartet (often referred to as "Kronos" or "The Kronos") plays contemporary classical music and was founded in 1973 by violinist David Harrington. Since 1978, they are based in San Francisco, California. Since 1985, the quartet's music has been released on Nonesuch Records.

Early recordings by the quartet contain contemporary classical music and adaptations of more popular music, such as jazz and rock and roll. Since the 1980s, and especially with the release of Cadenza on the Night Plain, written as a collaboration between composer Terry Riley and the quartet, much of the quartet's repertoire and album releases contain music written especially for them, by composers such as Terry Riley, Kevin Volans, Henryk Górecki, and Ástor Piazzolla. Their music "covers a who's who of 20th century-composers", as one critic noted in 1998.

Caravan (travellers)

A caravan (from Persian: کاروان‎‎) is a group of people traveling together, often on a trade expedition. Caravans were used mainly in desert areas and throughout the Silk Road, where traveling in groups aided in defense against bandits as well as helping to improve economies of scale in trade.

In historical times, caravans connecting East Asia and Europe often carried luxurious and lucrative goods, such as silks or jewelry. Caravans could therefore require considerable investment and were a lucrative target for bandits. The profits from a successfully undertaken journey could be enormous, comparable to the later European spice trade. The luxurious goods brought by caravans attracted many rulers along important trade routes to construct caravanserais, places where caravans could refresh their animals and supplies can be replenished. However, the volume a caravan could transport was limited even by Classical or Medieval standards. For example, a caravan of 500 camels could only transport as much as a third or half of the goods carried by a regular Byzantine merchant sailing ship.
