Alopecia universalis (AU), also known as alopecia areata universalis, is a medical condition involving the loss of all body hair, including eyebrows, eyelashes, chest hair, armpit hair, and pubic hair. It is the most severe form of alopecia areata. People with the disease are usually healthy and have no other symptoms and a normal life expectancy. Causes Alopecia universalis can occur at any age, and is currently believed to be an autoimmune disorder, in which a person's immune system attacks the hair follicles. Genetic factors may contribute to AU, as about 20% of those affected have a family member with alopecia. Treatment Many treatments have been explored, including immunomodulatory agents such as imiquimod. Tofacitinib citrate may also have benefits. In June 2014, a 25-year-old man with almost no hair on his body was reported to have grown full head of hair, as well as eyebrows, eyelashes, and facial, armpit, and other hair, following eight months of treatment.Contact immunotherapy involves the use of contact allergens, such as diphencyprone and squaric acid dibutylester...

The Sweet Track is an ancient trackway, or causeway, in the Somerset Levels, England, named after its finder, Ray Sweet. It was built in 3807 BC (determined using dendrochronology) and is the second-oldest timber trackway discovered in the British Isles, dating to the Neolithic. It is now known that the Sweet Track was predominantly built along the course of an earlier structure, the Post Track. The track extended across the now largely drained marsh between what was then an island at Westhay and a ridge of high ground at Shapwick, a distance close to 1,800 metres (5,900 ft) or around 1.1 mi. The track is one of a network that once crossed the Somerset Levels. Various artifacts and prehistoric finds, including a jadeitite ceremonial axe head, have been found in the peat bogs along its length.Construction was of crossed wooden poles, driven into the waterlogged soil to support a walkway that consisted mainly of planks of oak, laid end-to-end. The track was used for a period of only around ten years and was then abandoned, probably due to rising water levels. Following its discovery in 1970, most of the track has been left in its...

Ars nova (Latin for new art) refers to a musical style which flourished in the Kingdom of France and its surroundings during the Late Middle Ages. More particularly, it refers to the period between the preparation of the Roman de Fauvel (1310s) and the death of composer Guillaume de Machaut in 1377. The term is sometimes used more generally to refer to all European polyphonic music of the fourteenth century. For instance, the term "Italian ars nova" is sometimes used to denote the music of Francesco Landini and his compatriots, although Trecento music is the more common term for the contemporary 14th-century...

Acridotheres is a genus of starlings, the "typical" mynas, which are tropical members of the family Sturnidae. Distribution This genus has representatives in tropical southern Asia from Iran east to southern China and Indonesia. Two species have been introduced widely elsewhere. The common myna has been introduced to South Africa, Israel, Hawaii, North America, Australia and New Zealand, and the crested myna to the Vancouver region of British Columbia. Morphology The Acridotheres mynas are generally dark or dull birds with and fluted calls like most starlings; the sexes are similar. They walk and hop, and may share adaptations along with the Sturnus starlings that have modifications to the skull and its muscles for open bill probing or prying. They resemble the hill mynas (Gracula) with which they often co-occur, in having large white or buff wing patches which are obvious in flight and in some also naked areas on the head, but differ in that only the head plumage is glossy, and the underparts tend to be paler. The...
