Sea lettuce

The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.

Description

Individual blades of Ulva can grow to be more than 400mm (16") in size, but this only occurs when the plants are growing in sheltered areas. A macroscopic alga light to dark green in colour, attached by disc holdfast.

Nutrition

Sea lettuce is eaten by a number of different sea animals, including manatees and the sea slugs known as sea hares. Many species of sea lettuce are a food source for humans in Scandinavia, Great Britain, Ireland, China, and Japan (where this food is known as aosa). Sea lettuce as a food for humans is eaten raw in salads and cooked in soups. It is high in protein, soluble dietary fiber, and a variety of vitamins and minerals, especially iron.

Spring Heel Jack

Spring Heel Jack is an English electronic music duo, consisting of John Coxon and Ashley Wales.

Formed in 1993 in London, England, Spring Heel Jack began their career exploring drum and bass and jungle, but have since branched out into free improvisation and jazz, collaborating with many musicians from Europe and the United States.

History

Wales was formerly a composer of contemporary classical music and leader of the band Crazy About Love, while Coxon was a successful remixer and producer (most notably for Betty Boo) prior to their joining forces.

Their first three drum and bass albums released during the 1990s earned positive reviews for their innovative take on the genre. They also co-wrote and produced the 1996 track "Walking Wounded," a major UK hit for Everything But The Girl featuring Ben Watt who had earlier been sacked from Crazy About Love.

The cinematic Disappeared (2000) marked a transition for Wales and Coxon, and featured the British saxophonist John Surman, whose appearance was a harbinger of later changes.

Lettuce

Lettuce (Lactuca sativa) is an annual plant of the daisy family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce was first cultivated by the ancient Egyptians who turned it from a weed, whose seeds were used to produce oil, into a food plant grown for its succulent leaves, in addition to its oil-rich seeds. Lettuce spread to the Greeks and Romans, the latter of whom gave it the name lactuca, from which the English lettuce is ultimately derived. By 50 AD, multiple types were described, and lettuce appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century cultivars were described that can still be found in gardens. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world.

Generally grown as a hardy annual, lettuce is easily cultivated, although it requires relatively low temperatures to prevent it from flowering quickly. It can be plagued with numerous nutrient deficiencies, as well as insect and mammal pests and fungal and bacterial diseases. L. sativa crosses easily within the species and with some other species within the Lactuca genus; although this trait can be a problem to home gardeners who attempt to save seeds, biologists have used it to broaden the gene pool of cultivated lettuce varieties. World production of lettuce and chicory for calendar year 2010 stood at 23 620 000/23,620,000 tonnes, half of which came from China.
