257) Academy Award

Academy Award, in full Academy Award of Merit, byname Oscar, any of a number of awards presented annually by the Academy of Motion Picture Arts and Sciences, located in Beverly Hills, California, U.S., to recognize achievement in the film industry. The awards were first presented in 1929, and winners receive a gold-plated statuette commonly called Oscar.

Categories And Rules

Winners are chosen from the following 24 categories: best picture, actor, actress, supporting actor, supporting actress, directing, original screenplay, adapted screenplay, cinematography, production design, editing, original score, original song, costume design, makeup and hairstyling, sound mixing, sound editing, visual effects, foreign-language film, animated feature film, animated short, live-action short, documentary feature, and documentary short. The academy also presents scientific and technical awards, special achievement awards, honorary awards, the Jean Hersholt Humanitarian Award, the Irving G. Thalberg Memorial Award (for excellence in producing), and the Gordon E. Sawyer Award (for technological contributions), although these are not necessarily awarded annually.

In August 2018 the academy announced that it was adding an annual category for “outstanding achievement in popular film,” to debut at the 2019 ceremony. However, following criticism and confusion, the academy decided to postpone the introduction of the new category.

To be eligible for an award in a given year, a film must be publicly exhibited for paid admission for at least one week at a commercial theatre in Los Angeles county between January 1 and midnight of December 31 of that year. Exceptions to this rule include foreign-language films, which are submitted by their country of origin and need not have been shown in the United States. Documentaries and short films have different eligibility requirements and are officially submitted by their producers, whereas music awards require the musical artist to file a submission form.

Only members of the Academy of Motion Picture Arts and Sciences may nominate and vote for candidates for the Oscars. The academy is divided into various branches of film production, and the nominees in each award category are chosen by the members of the corresponding branch; thus, writers nominate writers, directors nominate directors, and so forth. The entire academy membership nominates the candidates for best picture and votes to determine the winners in most of the categories.
Aside from bestowing international recognition and prestige, an Academy Award can play a crucial role in the success of the major winners. The best picture award, for example, can significantly increase the box office earnings of the winning film. For actors and directors, the award often results in higher salaries, increased media attention, and better film offers.

History

When the academy was founded in 1927, the awards committee was only one of several that had been formed by the new organization. The idea of presenting awards was considered but not immediately pursued, because the academy was preoccupied with its role in labour problems, its efforts to improve the tarnished image of the film industry, and its function as a clearinghouse for the exchange of ideas about production procedures and new technologies. It was not until May 1928 that the academy approved the committee’s suggestions to present Academy Awards of Merit in 12 categories—most outstanding production, most artistic or unique production, and achievement by an actor, by an actress, in dramatic directing, in comedy directing, in cinematography, in art directing, in engineering effects, in original story writing, in adaptation writing, and in title writing.

The first awards covered films that had been released between August 1, 1927, and July 31, 1928. The awards were presented on May 16, 1929, in a ceremony at the Hollywood Roosevelt Hotel. The entire membership of the academy had nominated candidates in all categories. Five boards of judges (one from each of the academy’s original branches—actors, writers, directors, producers, and technicians) then determined the 10 candidates with the most votes in each category and narrowed those 10 down to 3 recommendations. A central board of judges, which consisted of one member from each branch, selected the final winners.

By the time of the second annual awards ceremony, on April 3, 1930 (honouring films from the second half of 1928 and from 1929), the number of categories was reduced to seven, and the two major film awards were collapsed into one, called best picture. The academy has since continued to make frequent alterations in rules, procedures, and categories. Indeed, so many changes have been made through the years that the only constant seems to be the academy’s desire to remain flexible and to keep abreast of the industry’s evolution. Among the most significant changes have been the decision in 1933 to alter the eligibility period for award consideration to the calendar year and the addition of the supporting actor and actress categories in 1936.

Originally the names of the award winners had been given to the press in advance with the stipulation that the information not be revealed until after the awards presentation. However, the Los Angeles Times printed the names of the 1939 winners in an early evening edition before the ceremony, draining the event of all its suspense during one of the industry’s biggest years. Thus, since then, the winners’ names have been a closely guarded secret until the official announcement at the awards ceremony.

The Academy Awards were first televised in the United States in 1953, and since 1969 they have been broadcast internationally. By the late 20th century, the ceremony had become a major happening, viewed by millions. Notable hosts over the years included Bob Hope, Johnny Carson, and Billy Crystal. Red-carpet interviews also became an integral part of the event, with much attention focused on the attendees’ ensembles. Steeply declining viewership in the late 2010s, however, led the academy to announce several changes to the ceremony’s broadcast, which included a limit of three hours, beginning in 2019, and an earlier air date, beginning in 2020.

Oscar Statuette

The design for the award statuette—a knight standing on a reel of film and holding a sword—is credited to Metro-Goldwyn-Mayer (MGM) art director Cedric Gibbons. Sculptor George Stanley was commissioned to create the original statuette based on Gibbons’s design. For many years the statuettes were cast in bronze, with 24-karat gold plating. During World War II the statuettes were made of plaster because of metal shortages. They are now made of gold-plated britannium. The design, however, has remained unchanged, with the exception of the pedestal base, the height of which was increased in 1945. The statuette stands 13.5 inches (34.3 cm) tall and weighs 8.5 pounds (3.8 kg).

The origins of the statuette’s nickname, Oscar, have been traced to three sources. Actress Bette Davisclaimed that the name derived from her observation that the backside of the statuette looked like that of her husband Harmon Oscar Nelson. Columnist Sidney Skolsky maintained that he gave the award its nickname to negate pretension. The name has also been attributed to academy librarian Margaret Herrick, who declared that the statuette looked like her Uncle Oscar. The true origin of the nickname has never been determined.

436) Ruth Benerito

Born January 22 1916, died October 5 2013.

Ruth Benerito, who has died aged 97, was an American chemist and inventor; among her 55 patents was a process for treating cotton that would lead to the creation of wash-and-wear fabrics, effectively revitalising America’s cotton industry.

From the early 1950s Ruth Benerito was a physical chemist at the Southern Regional Research Center for the United States Department of Agriculture (USDA), where her early work had focused on creating an intravenous fat emulsion that could be used to provide hospital patients with sufficiently high-calorie nutrition. In 1958, however, she became head of a research team hoping to develop a new cotton-based fabric, as easy to care for as the nylons and polyesters that had enjoyed such popularity in the post-war years.

Cotton’s biggest drawback, against its synthetic rivals, was its tendency to crease. This is down to the molecular structure of cotton fibres, which are comprised of long cellulose chains – polymers – held in place end-to-end by hydrogen bonds. Since these links are weak and easily broken, the heat and agitation of washing causes the molecules to shift position, resulting in the wrinkles that are corrected by ironing.

The secret to cotton that would not crease therefore lay in the chemical manipulation of the hydrogen bonds . The innovation that Ruth Benerito and her fellow researchers devised was a process called cross-linking, in which epoxides – ring-shaped organic compounds comprised of an oxygen atom and two other connected atoms – are inserted between cellulose chains like rungs in a ladder, creating a longer and sturdier polymer.

Though early treatments using formaldehyde as a cross-linking agent were not wholly successful – the formaldehyde proved toxic and caused an unpleasant smell – the implications extended far beyond crease-free fabric. Cross-linking with other compounds would later produce stain-resistant and fireproof clothes, while Ruth Benerito’s study of epoxides led to separate breakthroughs in the film and paper industries, in the creation of epoxy plastics, and in the preservation of wood.

The third of six children, she was born Ruth Mary Rogan in New Orleans, Louisiana, on January 22 1916. Her father, John, was a civil engineer; her mother, Bernadette, an artist and prototypical feminist. Both encouraged their daughter to pursue a scientific career from an early age. When she was 15 Ruth enrolled at Sophie Newcomb Memorial College, the women’s college of Tulane University, as one of the institution’s two female chemists, graduating with a BS in 1935, an MS in 1938 and a PhD from the University of Chicago in 1948. After earning her doctorate she became an assistant professor of chemistry at Newcomb College, a position she held until 1953 .

Following her departure from the USDA’s Southern Regional Research Center in 1989, Ruth Benerito taught Chemistry at the University of New Orleans, before macular degeneration forced her into permanent retirement aged 84. Her home of 56 years was destroyed by Hurricane Katrina, and she spent the last years of her life in Metairie, Louisiana.

Among the honours she received were the Federal Woman Award in 1968; the Garvan Medal from the American Chemical Society in 1970; and the Lemelson-Mit Lifetime Achievement Award in 2002. She was inducted into the National Inventors Hall of Fame in 2008.

Ruth Benerito was quick to play down her scientific contribution, citing the research that had preceded hers, and the properties of cotton itself. “Nature made cotton pretty good to begin with,” she insisted. “I just gave it a little boost.”

Her husband, Frank Benerito, whom she married in 1950, died in 1970.

256) Banana

Bananas are one of the world's most appealing fruits. Global banana exports reached about 18 million tons in 2015, according to the United Nations. About half of them went to the United States and the European market. In the United States, each person eats 11.4 lbs. of bananas per year, according to the U.S. Department of Agriculture, making it Americans' favorite fresh fruit.

A wide variety of health benefits are associated with the curvy yellow fruit. Bananas are high in potassium and pectin, a form of fiber, said Laura Flores, a San Diego-based nutritionist. They can also be a good way to get magnesium and vitamins C and B6.

"Bananas are known to reduce swelling, protect against developing type-2 diabetes, aid in weight loss, strengthen the nervous system and help with production of white blood cells, all due to the high level of vitamin B6 that bananas contain," Flores told Live Science.

"Bananas are high in antioxidants, which can provide protection from free radicals, which we come into contact with every day, from the sunlight to the lotion you put on your skin," Flores added.

From green to black

A 2017 meta-analysis published by Prilozi Section of Medical Sciences suggested that unripe green bananas offer some health benefits. They may help with controlling gastrointestinal problems such as diarrhea and ulcers, and may lower cholesterol and blood pressure. Some studies have suggested that the lectins in green bananas could provide treatment for HIV patients.

At the other end of a banana's life, research has shown that the levels of nutrients rise in bananas as they ripen. Bananas with dark spots were eight times more effective in enhancing the power of white blood cells than green-skin bananas, according to a 2009 study published in Food Science and Technology Research. White blood cells fight infections from bacteria, fungi, viruses and other pathogens.

Health benefits

Heart health

Bananas are good for your heart. They are packed with potassium, a mineral electrolyte that keeps electricity flowing throughout your body, which is required to keep your heart beating. Bananas' high potassium and low sodium content may also help protect your cardiovascular system against high blood pressure, according to the FDA.

A 2017 animal study conducted by researchers at the University of Alabama found that the potassium in bananas is also linked to arterial effectiveness; the more potassium you have, the less likely your arteries are to harden. In the study, mice with lower-potassium diet had harder arteries than mice consuming a normal amount of potassium. Arterial stiffness in humans is linked to heart disease.

Depression and mood

Bananas can be helpful in overcoming depression "due to high levels of tryptophan, which the body converts to serotonin, the mood-elevating brain neurotransmitter," Flores said. Plus, vitamin B6 can help you sleep well, and magnesium helps to relax muscles. Additionally, the tryptophan in bananas is well known for its sleep-inducing properties.

Digestion and weight loss

Bananas are high in fiber, which can help keep you regular. One banana can provide nearly 10 percent of your daily fiber requirement. Vitamin B6 can also help protect against type 2 diabetes and aid in weight loss, according to Flores. In general, bananas are a great weight loss food because they taste sweet and are filling, which helps curb cravings.

Bananas are particularly high in resistant starch, a form of dietary fiber in which researchers have recently become interested. A 2017 review published in Nutrition Bulletin found that the resistant starch in bananas may support gut health and control blood sugar. Resistant starch increases the production of short chain fatty acids in the gut, which are necessary to gut health.

Exercise

For replenishing energy and electrolytes, bananas can be more effective than sports drinks. A 2012 study published in PLOS One looked at male athletes competing in long-distance cycling races. They compared athletes refueling with Gatorade every 15 minutes to athletes refueling with a banana and water. Researchers saw that the athletes' performance times and body physiology were the same in both cases. But the banana's serotonin and dopamine improved the athletes' antioxidant capacity and helped with oxidative stress, improving performance overall.

Vision

Carrots may get all the glory for helping your eyes, but bananas do their share as well. The fruits contain a small but significant amount of vitamin A, which is essential for protecting your eyes, maintaining normal vision and improving vision at night, according to the National Institutes of Health. Vitamin A contains compounds that preserve the membranes around your eyes and are an element in the proteins that bring light to your corneas. Like other fruits, bananas can help prevent macular degeneration, an incurable condition, which blurs central vision.

Bones

Bananas may not be overflowing with calcium, but they are still helpful in keeping bones strong. According to a 2009 article in the Journal of Physiology and Biochemistry, bananas contain an abundance of fructooligosaccharides. These are nondigestive carbohydrates that encourage digestive-friendly priobotics and enhance the body's ability to absorb calcium.

Cancer

Some evidence suggests that moderate consumption of bananas may be protective against kidney cancer. A 2005 Swedish study found that women who ate more than 75 servings of fruits and vegetables cut their risk of kidney cancer by 40 percent, and that bananas were especially effective. Women eating four to six bananas a week halved their risk of developing kidney cancer.

Bananas may be helpful in preventing kidney cancer because of their high levels of antioxidant phenolic compounds.

Pregnancy

Bananas may also help prevent gestational diabetes. Lack of sleep during pregnancy can contribute to gestational diabetes, according to a meta-analysis published in Sleep Medicine Reviews. But the magnesium and tryptophan in bananas can help ensure a good night's rest.

Health risks

Eaten in moderation, there are no significant side effects associated with eating bananas. However, eating the fruits in excess may trigger headaches and sleepiness, Flores said. She said that such headaches are caused by "the amino acids in bananas that dilate blood vessels." Overripe bananas contain more of these amino acids than other bananas. "Bananas can also contribute to sleepiness when eaten in excess due to the high amount of tryptophan found in them," she said. Magnesium also relaxes the muscles — another sometimes-benefit, sometimes-risk.

Bananas are a sugary fruit, so eating too many and not maintaining proper dental hygiene practices can lead to tooth decay. They also do not contain enough fat or protein to be a healthy meal on their own, or an effective post-workout snack.

Eating bananas becomes significantly risky only if you eat too many. The USDA recommends that adults eat about two cups of fruit a day, or about two bananas. If you eat dozens of bananas every day, there may be a risk of excessively high vitamin and mineral levels.

The University of Maryland Medical Center reported that potassium overconsumption can lead to hyperkalemia, which is characterized by muscle weakness, temporary paralysis and an irregular heartbeat. It can have serious consequences, but you would have to eat about 43 bananas in a short time for any symptoms of hyperkalemia to occur.

According to the NIH, consuming more than 500 milligrams of vitamin B6 daily can possibly lead to nerve damage in the arms and legs. You would have to eat thousands of bananas to reach that level of vitamin B6.

Banana peels: edible or poisonous?

It turns out that the biggest risk from a banana peel might really be slipping on it. Banana peels are not poisonous. In fact, they're edible, and packed with nutrients. "Banana peel is eaten in many parts of the world, though [it's] not very common in the West," Flores said. "It contains high amounts of vitamin B6 and B12, as well as magnesium and potassium. It also contains some fiber and protein." According to a 2011 article in the journal of Applied Biochemistry and Biotechnology, banana peels also have "various bioactive compounds like polyphenols, carotenoids and others."

It is important to carefully wash a banana peel before eating it due to the pesticides that may be sprayed in banana groves.

Banana peels are usually served cooked, boiled or fried, though they can be eaten raw or put in a blender with other fruits. They are not as sweet as banana flesh. Riper peels will be sweeter than unripe ones.

Other banana facts

Bananas may have been the world's first cultivated fruit. Archaeologists have found evidence of banana cultivation in New Guinea as far back as 8000 B.C.
The banana plant is classified as an arborescent (tree-like) perennial herb, and the banana itself is considered a berry. A bunch of bananas is called a hand; a single banana is a finger.

There are almost 1,000 varieties of bananas, according to the Food and Agriculture Organization of the United Nations (FAO). Nearly all the bananas sold in stores are cloned from just one variety, the Cavendish banana plant, originally native to Southeast Asia. The Cavendish replaced the Gros Michel after that variety was wiped out by fungus in the 1950s. The Gros Michel reportedly was bigger, had a longer shelf life and tasted better. The Cavendish are resistant to the fungus that killed off the Gros Michel, but they are susceptible to another fungus and may face the same fate within the next 20 years, botanists say.

Botanically, there is no difference between plantains and bananas. But in general use, "banana" refers to the sweeter form of the fruit, which is often eaten uncooked, while "plantain" refers to a starchier fruit that is often cooked before eating.

Ecuador is the leading producer of bananas worldwide, followed by the Philippines. Bananas are produced in other tropical and subtropical areas of Asia, Africa, and the Americas, as well as the Canary Islands and Australia.

Wild bananas grow throughout Southeast Asia, but most are inedible for humans, as they are studded with hard seeds.
