Captive breeding is the process of breeding animals in human controlled environments with restricted settings, such as wildlife reserves, zoos and other conservation facilities; sometimes the process is construed to include release of individual organisms to the wild, when there is sufficient natural habitat to support new individuals or when the threat to the species in the wild is lessened. Captive breeding has been used with success for some species for some time, with probably the oldest known instances of captive breeding being attributed to menageries of European and Asian rulers, a case in point being the Pere David's Deer. The idea was popularized among modern conservationists independently by Peter Scott and Gerald Durrell in the 1950s and 1960s, founders of the Wildfowl and Wetlands Trust and Jersey Zoo - who demonstrated success with a wide variety of life forms in the 1970s ranging from birds (e.g. Pink Pigeon), mammals (e.g. Pygmy Hog), reptiles (e.g. Round Island Boa) and amphibians (e.g. Poison arrow frogs). Their ideas were independently validated by the success of Operation Oryx (under the auspices of the Fauna and Flora Preservation Society), which captive bred the Arabian Oryx starting in 1963 for eventual reintroduction to the wild. The Przewalski's horse has recently been re-introduced to the wild in Mongolia, its native habitat. Such techniques are usually difficult to implement for highly mobile species like some migratory birds (e.g. cranes) and fishes (e.g. Hilsa). If the captive breeding population is too small, inbreeding may occur due to reduced gene pool, which may lead to the population lacking immunity to diseases and other problems. Over sufficient number of generations, inbred populations can regain "normal" genetic diversity. Another challenge with captive breeding is the habitat loss that occurs while they are in captivity (though it is occurring even before they are captured). This may make release of the species unviable if there is no habitat left to support larger populations. The Sumatran Rhino will not survive purely in captivity and loss of habitat is a major factor in their extinction. If their habitat disappears, captive populations as well as wild ones will disappear along with it. [READ THE REST OF THIS ARTICLE]

Lyle Martin Alzado was a professional American football defensive lineman of the National Football League who played 15 seasons for the Denver Broncos, Cleveland Browns and Oakland Raiders. He was drafted in the 4th round (79th overall) of the 1971 NFL Draft by the Broncos. He played college football at Yankton College. Throughout his career, Alzaldo was famous for his intense and intimidating style of play. In 196 career games, he racked up 112.5 sacks and earned two Pro Bowl selections in 1977 and 1978. He would spend his last years in the league with the Oakland Raiders where he would win a championship in Super Bowl XVIII. In 1982 he was voted the NFL Comeback Player of the Year. Although he played a full season in 1981, his play was seemingly so superior in 1982 that he garnered the award. In the strike-shortened 1982 season of 9 games, Alzado recorded 7 sacks and 30 tackles while being voted All-AFC. This was the sixth season out of his first twelve campaigns that he received some sort of post-season honor. Alzado was one of the fiercest competitors the NFL has ever seen. In fact, due to Alzado throwing an opponent's helmet across the field, the league instituted a rule specifically banning the act. He continued to perform well for the Raiders in the 1983 season, helping lead them to a Super Bowl that year while recording 50 tackles and 7½ sacks. He also had an outstanding 1984 season with 63 tackles and 6 sacks, but was injured part way through 1985 and retired at the end of the year. His tackle and sack totals dipped to 31 and 3. Alzado is probably most remembered today for being one of the first major U.S. sports figures to admit using steroids. In the last years of his life, as he battled against the brain tumor that eventually caused his death at the age of 43, Alzado asserted that his steroid abuse directly led to his fatal illness, but each of his physicians stated it could not be true, and that while steroids do have harsh side effects, they were not the cause of his brain cancer. According to some reports, Alzado was using natural growth hormone, harvested from human corpses, as opposed to synthetic growth hormones. Alzado is buried at River View Cemetery in Portland, Oregon.

Cheese is a generic term for a diverse group of milk-based food products. Cheese is produced throughout the world in wide-ranging flavors, textures, and forms. Cheese consists of proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. It is produced by coagulation of the milk protein casein. Typically, the milk is acidified and addition of the enzyme rennet causes coagulation. The solids are separated and pressed into final form. Some cheeses have molds on the rind or throughout. Most cheeses melt at cooking temperature. Hundreds of types of cheese are produced. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurized, the butterfat content, the bacteria and mold, the processing, and aging. Herbs, spices, or wood smoke may be used as flavoring agents. The yellow to red color of many cheeses is from adding annatto. For a few cheeses, the milk is curdled by adding acids such as vinegar or lemon juice. Most cheeses are acidified to a lesser degree by bacteria, which turn milk sugars into lactic acid, then the addition of rennet completes the curdling. Vegetarian alternatives to rennet are available; most are produced by fermentation of the fungus Mucor miehei, but others have been extracted from various species of the Cynara thistle family. Cheese is valued for its portability, long life, and high content of fat, protein, calcium, and phosphorus. Cheese is more compact and has a longer shelf life than milk. Cheesemakers near a dairy region may benefit from fresher, lower-priced milk, and lower shipping costs. The long storage life of some cheese, especially if it is encased in a protective rind, allows selling when markets are favorable. [READ THE REST OF THIS ARTICLE]

The Ronald Reagan assassination attempt occurred on Monday, March 30, 1981, just 69 days into the presidency of Ronald Reagan. While leaving a speaking engagement at the Washington Hilton Hotel in Washington, D.C., President Reagan and three others were shot and wounded by John Hinckley, Jr.. Reagan suffered a punctured lung, but prompt medical attention allowed him to recover quickly. Reagan was the first serving United States president to survive being shot in an assassination attempt. No formal invocation of presidential succession took place, although a controversial statement by Secretary of State Alexander Haig that he was "in control here" marked a short period during which Vice President George H. W. Bush was physically absent, flying back to Washington, D.C., aboard Air Force Two from a speech in Fort Worth, Texas. Hinckley was found not guilty by reason of insanity and has remained confined to a psychiatric facility. The motivation behind Hinckley's attack stemmed from an obsession with actress Jodie Foster due to erotomania. While living in Hollywood in the late 1970s, he saw the film Taxi Driver at least 15 times, apparently identifying strongly with Travis Bickle, the lead character. The arc of the story involves Bickle's attempts to protect a 12-year-old child prostitute, played by Foster; toward the end of the film, Bickle attempts to assassinate a United States Senator who is running for president. Shortly before 2:30 PM EST, as Reagan walked out of the hotel's T Street NW exit toward his waiting car, Hinckley emerged from the crowd of admirers and fired a Röhm RG-14 .22 cal. blue steel revolver six times in three seconds, missing the President with all six shots. The first bullet hit White House Press Secretary James Brady in the head. The second hit District of Columbia police officer Thomas Delahanty in the back. The third overshot the president and hit the window of a building across the street. The fourth hit Secret Service agent Timothy McCarthy in the abdomen. The fifth hit the bullet-resistant glass of the window on the open side door of the president's limousine. The sixth and final bullet ricocheted off the side of the limousine and hit the president in his left underarm, grazing a rib and lodging in his lung, stopping nearly an inch from his heart.
