Introduction to viruses

Introduction to viruses.
A virus is an infectious agent that reproduces inside the cells of living hosts. Unlike most living things, viruses do not have cells that divide; instead they force infected host cells to produce thousands of identical copies of the original virus, at an extraordinary rate. A virus consists of two or three parts: genes, made from either DNA or RNA, long molecules that carry the genetic information; a protein coat that protects the genes; and in some, an envelope of fat that surrounds and protects them when they are not contained within a host cell (and makes them vulnerable to soap). Viruses spread in different ways; some through the air by people when they cough or sneeze, others by the faecal–oral route, and some by direct contact or during sex. Over 4,800 species have been discovered, many of which cause disease in plants and animals, including common human diseases such as the common cold, chickenpox and cold sores, and serious epidemics and pandemics such as HIV, Ebola, influenza, SARS and COVID-19.

Ubinas

Ubinas.
Ubinas is a stratovolcano in the Moquegua Region of southern Peru, 60 kilometres (37 mi) east of the city of Arequipa. Part of the Central Volcanic Zone of the Andes, it rises 5,672 metres (18,609 ft) above sea level. Its summit is cut by a caldera 1.4 kilometres (0.87 mi) wide and 150 metres (490 ft) deep, which itself contains a smaller crater. Below the summit, Ubinas is a steep cone with a prominent notch on the southern side. The most active volcano in Peru, it has a history of small- to moderate-sized explosive eruptions and persistent degassing and ash emissions. An eruption in 1667, its largest since prehistoric times, produced scoria falls and pyroclastic flows. In 2006 and 2007 eruption columns led to ash fall in the region, resulting in health issues and evacuations. During the most recent activity, from 2013 to 2019, a lava flow formed inside the crater, and as ash fell, surrounding towns had to be evacuated.

Megarachne

Megarachne.
Megarachne was a predatory freshwater arthropod of the order of eurypterids, often called sea scorpions. Two fossil specimens of the genus have been discovered, in San Luis, Argentina, in deposits of Late Carboniferous age from the Gzhelian stage. Megarachne ("great spider") was initially misidentified as a spider. With a body length of 54 cm (1.77 ft), it was a medium-sized eurypterid, similar to others within the Mycteropoidea, a rare group known primarily from South Africa and Scotland. The mycteropoids evolved a specialized method of feeding referred to as sweep-feeding, raking through the substrate of riverbeds to capture and eat smaller invertebrates. Due to their fragmentary fossil record and similarities between the genera, Megarachne and two other members of its family, Mycterops and Woodwardopterus, have been hypothesized to represent different developmental stages of a single genus.

Hours of Mary of Burgundy

Hours of Mary of Burgundy.
The Hours of Mary of Burgundy is a book of hours, a form of devotional book for lay people, completed in Flanders around 1477. It was probably commissioned for Mary of Burgundy, then the wealthiest woman in Europe; Mary was the only child of Charles the Bold, Duke of Burgundy, and wife of Maximilian I, ruler of the Holy Roman Empire. The book contains 187 folios (folio 14v pictured), each measuring 22.5 by 15 centimetres (8.9 in × 5.9 in). It consists of the Roman Liturgy of the Hours, 24 calendar roundels, 20 full-page miniatures and 16 quarter-page format illustrations. It includes meticulously detailed illustrations and borders by the influential illuminator known by the notname of the Master of Mary of Burgundy. Other miniatures, considered of an older tradition, were contributed by Simon Marmion, Willem Vrelant and Lieven van Lathem. The two best-known illustrations contain a revolutionary trompe-l'œil technique of showing a second perspective through an open window.

Island of stability

Island of stability.
The island of stability in nuclear physics is a predicted set of isotopes of superheavy elements whose half-lives may be considerably longer than those experimentally observed for these elements. Its theoretical existence is attributed to stabilizing effects of closed nuclear shells and magic numbers of protons and neutrons. The island of stability is generally thought to center near copernicium and flerovium isotopes with around 184 neutrons, separated from known stable and long-lived nuclides. While stabilizing effects are expected to be greatest for nuclides with around 114 protons, other islands of stability might also exist around heavier nuclides with higher magic numbers. Estimates of the stability of elements on the island are usually around a half-life of minutes or days, with some estimates of up to millions of years. The synthesis of nuclides with up to 118 protons and 177 neutrons has demonstrated a slight stabilizing effect supporting the island's existence.

Aries (album)

Aries (album).
Aries is the ninth studio album by Mexican recording artist Luis Miguel (pictured). Released by WEA Latina in 1993, it features pop ballads and dance numbers with R&B influences. "Ayer" and "Hasta Que Me Olvides", two of the album's three singles released for sale, topped the US Billboard Hot Latin Songs chart. "Hasta el Fin" and "Tú y Yo" were released as promotional singles, both peaking at number four on that chart. Aries stayed at number one on the US Billboard Latin Pop Albums for 19 weeks. It sold over one million copies in Mexico, and over two million copies worldwide through 2000. Upon its release, the album received mixed reviews from music critics; they were divided on the dance tunes and ballads, although Miguel's vocals and the album's arrangements garnered positive reactions. The Aries Tour promoted the record in Latin America and the United States. Miguel received several accolades for the album, including the Grammy Award for Best Latin Pop Album.

Sonestown Covered Bridge

Sonestown Covered Bridge.
The Sonestown Covered Bridge is a Burr arch truss covered bridge over Muncy Creek in Davidson Township, Sullivan County, in the U.S. state of Pennsylvania. Built c. 1850, the bridge is 110 feet (34 m) long, and was placed on the National Register of Historic Places (NRHP) in 1980. The bridge is named for the nearby unincorporated village of Sonestown; it was built to provide access to a gristmill, which operated until the early 20th century. The bridge construction is cruder than the other two surviving covered bridges in Sullivan County, with each Burr arch formed from six straight beams set at angles instead of a smooth curve. Despite being repaired or restored several times from 1969, as of 2016 the bridge was deemed "deemed "basically intolerable requiring high priority of corrective action" on the National Bridge Inventory. It is the shortest covered bridge in the county and as of 2015 had average daily traffic of 50 vehicles.

Arnold Bax

Arnold Bax.
Arnold Bax (1883–1953) was an English composer, poet, and author. Best known for his orchestral music, he also wrote songs, choral music, chamber pieces, and solo piano works. In addition to a series of symphonic poems, he wrote seven symphonies, and was for a time widely regarded as the leading British symphonist. Bax was born in Streatham to a prosperous family who encouraged his music career, and his private income enabled him to follow his own path as a composer without regard for fashion or orthodoxy. While still a student at the Royal Academy of Music, Bax became fascinated with Ireland and the Celtic Revival. In the years before the First World War he lived in Ireland and became a member of Dublin literary circles, writing fiction and verse under the pseudonym Dermot O'Byrne. His best-known work is the symphonic poem Tintagel (1917). In 1942 Bax was appointed Master of the King's Music.

William F. Raynolds

William F. Raynolds.
William F. Raynolds (March 17, 1820 – October 18, 1894) was an explorer, engineer and army officer who served in the Mexican–American War and the American Civil War. He oversaw the construction of numerous lighthouses; at least six of them are still standing and in use. During the occupation of Mexico in 1848, Raynolds led a party that was the first to summit Pico de Orizaba, the highest mountain in Mexico and believed at that time to be the highest in North America. In 1859, Raynolds was placed in charge of the first government-sponsored expedition into the Yellowstone region. Heavy snowpack prevented the expedition from reaching the Yellowstone Plateau, forcing them to cross Union Pass in the Wind River Range. The expedition then entered Jackson Hole and surveyed the Teton Range, now within Grand Teton National Park. Raynolds retired from the army in 1884 with the rank of colonel after a 40-year career.

Bridgeport, Connecticut, Centennial half dollar

Bridgeport, Connecticut, Centennial half dollar.
The Bridgeport, Connecticut, Centennial half dollar is a fifty-cent piece issued by the United States Bureau of the Mint in 1936 as a commemorative coin. Designed by Henry Kreis, the obverse (pictured) depicts the showman P. T. Barnum, who was one of Bridgeport's most famous residents, mayor of the city, helped develop it, and is buried there. Bridgeport authorities wanted a commemorative coin, and authorizing legislation passed Congress without opposition. Kreis had designed the Connecticut Tercentenary half dollar (1935), and he produced designs showing Barnum and a modernistic eagle similar to the one on the Connecticut piece. The coins were vended to the public beginning in September 1936 at a price of $2. Too late for most of the centennial celebrations, the coins sold well. Unsold pieces were bought up by coin dealers and wholesale quantities were available on the secondary market until the 1970s. The Bridgeport half dollar sells in the low hundreds of dollars, depending on condition.

Alloxylon pinnatum

Alloxylon pinnatum.
Alloxylon pinnatum, the Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either lobed and up to 30 cm (12 in) long, or spear-shaped and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads with 50 to 140 individual flowers appear in spring and summer. These are followed by rectangular woody seed pods, which bear two rows of winged seeds. Known for many years as Oreocallis pinnata, it was transferred to the new genus Alloxylon by Peter Weston and Mike Crisp in 1991; the genus contains four species previously classified in Oreocallis that are found in Australasia. The tree's terminal tubular flowers indicate that it is pollinated by birds. Classified as "near threatened" under the Queensland Nature Conservation Act 1992, the Dorrigo waratah has proven difficult to keep alive in cultivation.
