Chupacabra

The chupacabra or chupacabras (, literally 'goat-sucker'; from chupa, 'sucks', and cabras, 'goats') is a legendary creature, or cryptid, in the folklore of parts of the Americas. The name comes from the animal's reported vampirism—the chupacabra is said to attack and drink the blood of livestock, including goats.

Physical descriptions of the creature vary. In Puerto Rico and in Hispanic America it is generally described as a heavy creature, reptilian and alien-like, roughly the size of a small bear, and with a row of spines reaching from the neck to the base of the tail, while in the Southwestern United States it is depicted as more dog-like.

Initial sightings and accompanying descriptions first occurred in Puerto Rico in 1995. The creature has since been reported as far north as Maine, as far south as Chile, and even outside the Americas in countries like Russia and Philippines. All of the reports are anecdotal and have been disregarded as uncorroborated or lacking evidence. Sightings in northern Mexico and the southern United States have been verified as canids afflicted by mange.

Name
Chupacabras can be literally translated as 'goat-sucker', from chupar ('to suck') and cabras ('goats'). It is known as both chupacabras and chupacabra throughout the Americas, with the former being the original name, and the latter a regularization. The name is attributed to Puerto Rican comedian Silverio Pérez, who coined the label in 1995 while commenting on the attacks as a San Juan radio deejay.

History
In 1975, a series of livestock killings in the small town of Moca, Puerto Rico were attributed to el vampiro de Moca ('the vampire of Moca'). Initially, it was suspected that the killings were committed by a Satanic cult; later more killings were reported around the island, and many farms reported loss of animal life. Each of the animals was reported to have had its body bled dry through a series of small circular incisions.

The first reported attack eventually attributed to the actual chupacabras occurred in March 1995. Eight sheep were discovered dead in Puerto Rico, each with three puncture wounds in the chest area and reportedly completely drained of blood. A few months later, in August, an eyewitness named Madelyne Tolentino reported seeing the creature in the Puerto Rican town of Canóvanas, where as many as 150 farm animals and pets were reportedly killed.

Puerto Rican comedian and entrepreneur Silverio Pérez is credited with coining the term chupacabras soon after the first incidents were reported in the press. Shortly after the first reported incidents in Puerto Rico, other animal deaths were reported in other countries, such as Argentina, Bolivia, Brazil, Chile, Colombia, Dominican Republic, El Salvador, Honduras, Mexico, Nicaragua, Panama, Peru, and the United States.

In 2019 a video recorded by Mundo Ovni showed the results of a supposed attack on chickens in the Seburuquillo sector of Lares, Puerto Rico.

Reputed origin
A five-year investigation by Benjamin Radford, documented in his 2011 book Tracking the Chupacabra, concluded that the description given by the original eyewitness in Puerto Rico, Madelyne Tolentino, was based on the creature Sil in the 1995 science-fiction horror film Species. The alien creature Sil is nearly identical to Tolentino's chupacabra eyewitness account and she had seen the movie before her report: "It was a creature that looked like the chupacabra, with spines on its back and all... The resemblance to the chupacabra was really impressive", Tolentino reported. Radford revealed that Tolentino "believed that the creatures and events she saw in Species were happening in reality in Puerto Rico at the time", and therefore concludes that "the most important chupacabra description cannot be trusted". This, Radford believes, seriously undermines the credibility of the chupacabra as a real animal.

The reports of blood-sucking by the chupacabra were never confirmed by a necropsy, the only way to conclude that the animal was drained of blood. Dr. David Morales, a Puerto Rican veterinarian with the Department of Agriculture, analyzed 300 reported victims of the chupacabra and found that they had not been bled dry.

Radford divided the chupacabra reports into two categories: the reports from Puerto Rico and Latin America, where animals were attacked and it is supposed their blood was extracted; and the reports in the United States of mammals, mostly dogs and coyotes with mange, that people call "chupacabra" due to their unusual appearance.

In 2010, University of Michigan biologist Barry O'Connor concluded that all the chupacabra reports in the United States were simply coyotes infected with the parasite Sarcoptes scabiei, whose symptoms would explain most of the features of the chupacabra: they would be left with little fur, thickened skin, and a rank odor. O'Connor theorized that the attacks on goats occurred "because these animals are greatly weakened, [so] they're going to have a hard time hunting. So they may be forced into attacking livestock because it's easier than running down a rabbit or a deer." Both dogs and coyotes can kill and not consume the prey, either because they are inexperienced, or due to injury or difficulty in killing the prey. The prey can survive the attack and die afterwards from internal bleeding or circulatory shock. The presence of two holes in the neck, corresponding with the canine teeth, are to be expected since this is the only way that most land carnivores have to catch their prey. There are reports of stray Mexican hairless dogs being mistaken for chupacabras.

Appearance
The most common description of the chupacabra is that of a reptile-like creature, said to have leathery or scaly greenish-gray skin and sharp spines or quills running down its back. It is said to be approximately 3 to 4 ft high, and stands and hops in a fashion similar to that of a kangaroo. This description was the chief one given to the few Puerto Rican reports in 1995 that claimed to have sighted the creature, with similar reports in parts of Chile and Argentina following.

Another common description of the chupacabra is of a strange breed of wild dog. This form is mostly hairless and has a pronounced spinal ridge, unusually pronounced eye sockets, fangs, and claws. This description started to appear in the early 2000s from reports trailing north from the Yucatán Peninsula, northern Mexico, and then into the United States; becoming the predominant description since. Unlike conventional predators, the chupacabra is said to drain all of the animal's blood (and sometimes organs) usually through three holes in the shape of a downwards-pointing triangle, but sometimes through only one or two holes.

Plausibility of existence
The chupacabra panic first started in late 1995, Puerto Rico: farmers were mass reporting the mysterious killings of various livestock. In these reports, the farmers recalled two puncture wounds on the animal carcasses. Chupacabra killings were soon associated with a seemingly untouched animal carcass other than puncture wounds which were said to be used to suck the blood out of the victim. Reports of such killings began to spread around and eventually out of the country, reaching areas such as Mexico, Brazil, Chile, and the Southern area of the United States.

Most notably, these areas experience frequent, and extreme dry seasons; in the cases of the Puerto Rican reports of 1995 and the Mexican reports of 1996, both countries were currently experiencing or dealing with the aftermath of severe droughts. Investigations carried out in both countries at this time noted a certain dramatic violence in these killings. These environmental conditions could provide a simple explanation for the livestock killings: wild predators losing their usual prey to the drought, therefore being forced to hunt the livestock of farmers for sustenance. Thus, the same theory can be applied to many of the other ‘chupacabra’ attacks: that the dry weather had created a more competitive environment for native predators, leading them to prey on livestock to survive. Such an idea can also explain the increased violence in the killings; hungry and desperate predators are driven to hunt livestock to avoid starvation, causing an increase in both the number of livestock killings, and the viciousness of each one.

Evidence of such is provided in page 179 of Benjamin Radford’s book, Tracking the Chupacabra: The Vampire Beast in Fact, Fiction, and Folklore. Radford’s chart highlights ten significant reports of chupacabra attacks, seven of which had a carcass recovered and examined; these autopsies concluded the causes of death as various animal attacks, as displayed though the animal DNA found on the carcasses. Radford provides further evidence in pages 161-162 of his book, displaying animals who are proven to have fallen victim to regular coyote attacks; thus, explaining that it is not unusual for an animal carcass to be left uneaten while only displaying puncture wounds and/or minimal signs of attack.

The plausibility of the chupacabra’s existence is also discredited by the varying descriptions of the creature. Depending on the reported sighting, the creature is described with thick skin or fur, wings or no wings, a long tail or no tail, is bat-like, dog-like, or even alien-like. Evidently, the chupacabra has a wide variety of descriptions; to the point where it is hard to believe that all the sightings are of the same creature. A very likely explanation for this phenomenon is that individuals who had heard of the newly popular chupacabra had the creature’s name fresh in their mind before they happened to see a strange looking animal. They then resort to make sense of their encounter by labelling it as the recently ‘discovered’ monster, instead of a more realistic explanation. For example, some scientists hypothesize that what many believe to be a chupacabra is a wild or domestic dog affected by mange, a disease causing a thick buildup of skin and hair loss.

Related legends
The "Ozark Howler", a large bear-like animal, is the subject of a similar legend.

The Peuchens of Chile also share similarities in their supposed habits, but instead of being dog-like they are described as winged snakes. This legend may have originated from the vampire bat, an animal endemic to the region.

In the Philippines the Sigbin shares many of the chupacabra's descriptions.

"Grunches" is a legend in New Orleans that gets its name from a lovers' lane called Grunch Road, between the Mississippi River and the Gulf of Mexico. The road was said to be inhabited by creatures called "grunches", similar in appearance to the Chupacabra.

In 2018 there were reports of suspected chupacabras in Manipur, India. Many domestic animals and poultry were killed in a manner similar to other chupacabra attacks, and several people reported that they had seen creatures. Forensic experts opined that street dogs were responsible for mass killing of domestic animals and poultry after studying the remnants of a corpse.

Cayuga Lake

Cayuga Lake (, or ) is the longest of central New York's glacial Finger Lakes, and is the second largest in surface area (marginally smaller than Seneca Lake) and second largest in volume. It is just under 39 mi long. Its average width is 2.8 km, and it is 3.5 mi at its widest point, near Aurora. It is approximately 435 ft at its deepest point, and has over 95 mi of shoreline.

The lake is named after the indigenous Cayuga people.

Location
The city of Ithaca, site of Ithaca College and Cornell University, is located at the southern end of Cayuga Lake.

Villages and settlements along the east shore of Cayuga Lake include Myers, King Ferry, Aurora, Levanna, Union Springs, and Cayuga. Settlements along the west shore of the lake include Sheldrake, Poplar Beach, and Canoga.

The lake has two small islands. One is near Union Springs, called Frontenac Island (northeast); this island is not inhabited. The other island, Canoga Island (northwest), is located near the town of Canoga. This island has several camps and is inhabited during the summer months. The only other island in any of the Finger Lakes is Skenoh Island in Canandaigua Lake.

Geographical characteristics
The lake depth, with steep east and west sides and shallow north and south ends, is typical of the Finger Lakes, as they were carved by glaciers during the last ice age.

The water level is regulated by the Mud Lock at the north end of the lake. It is connected to Lake Ontario by the Erie Canal and Seneca Lake by the Seneca River. The lake is drawn down as winter approaches, to minimize ice damage and to maximize its capacity to store heavy spring runoff.

The north end is dominated by shallow mudflats. An important stopover for migratory birds, the mudflats and marsh are the location of the Montezuma National Wildlife Refuge. The southern end is also shallow and often freezes during the winter.

Human impact

Cayuga Lake is very popular among recreational boaters. The Allan H. Treman State Marine Park, with a large state marina and boat launch, is located at the southern end of the lake in Ithaca. There are two yacht clubs on the western shore: Ithaca Yacht Club, a few miles north of Ithaca, and Red Jacket Yacht Club, just south of Canoga. There are several other marinas and boat launches, scattered along the lake shore.

Cayuga Lake is the source of drinking water for several communities, including Lansing, near the southern end of the lake along the east side, which draws water through the Bolton Point Water System. There are also several lake source cooling systems that are in operation on the lake, whereby cooler water is pumped from the depths of the lake, warmed, and circulated in a closed system back to the surface. One of these systems, which is operated by Cornell University and began operation in 2000, was controversial during the planning and building stages, due to its potential for having a negative environmental impact. However, all of the environmental impact reports and scientific studies have shown that the Cornell lake source cooling system has not yet had, and will not likely have any measurably significant environmental impact. Furthermore, Cornell's system pumps significantly less warm water back into the lake than others further north, which have been operating for decades, including the coal-fired power plant on the eastern shore.

The AES Coal Power plant was shut down in August 2019, and there are plans to convert it into a data center in the near future. The plant used to use Cayuga Lake as a cooling source. In the late 1960s, citizens successfully opposed the construction of an 830-MW nuclear power plant on the shore of Cayuga Lake.

Rod Serling named his production company Cayuga Productions, during the years of his TV series, The Twilight Zone. Serling and his family had a summer home at Cayuga Lake.

Fishing
The fish population is managed and substantial sport fishing is practiced, with anglers targeting smelt, lake trout and smallmouth bass. Fish species present in the lake include lake trout, landlocked salmon, brown trout, rainbow trout, smallmouth bass, smelt, alewife, atlantic salmon, black crappie, bluegill, pickerel, largemouth bass, northern pike, pumpkinseed sunfish, rock bass, and yellow perch. The round goby has been an invasive species in the lake since the 1990s. There are state owned hard surface ramps in Cayuga–Seneca Canal, Lock #1 (Mud Lock), Long Point State Park, Cayuga Lake State Park, Deans Cove Boat Launch, Taughannock Falls State Park, and Allan H. Treman State Marine Park.

Tributaries
The major inflows to the lake are: Fall Creek, Cayuga Inlet, Salmon Creek, Taughannock Creek, and Six Mile Creek; while the lake outflows into the Seneca River and other tributaries. Ungaged tributaries that inflow to the lake include:

 * Barnum Creek
 * Bergen Creek
 * Big Hollow Creek
 * Bloomer Creek
 * Canoga Creek
 * Dean Creek
 * Demont Creek
 * Glen Creek
 * Glenwood Creek
 * Great Gully Brook
 * Groves Creek
 * Gulf Creek
 * Indian Creek
 * Little Creek
 * Lively Run
 * Mack Creek
 * Minnegar Brook
 * Morrow Creek
 * Paines Creek
 * Red Creek
 * Schuyler Creek
 * Sheldrake Creek
 * Trumansburg Creek
 * Williams Brook
 * Willow Creek
 * Yawger Creek

Folklore

The lake is the subject of local folklore.

An Ithaca Journal article of January 5, 1897, reported that a sea serpent, nicknamed "Old Greeny," had been sighted in Cayuga Lake annually for 69 years. A sighting in that month described the animal, 200 ft from shore, as "large and its body long," though a "tramp" suggested it was a muskrat. In 1929, two creatures, about 12 to 15 ft in length, were reportedly spotted along the eastern shore of the lake. Further sightings were reported in 1974 and 1979.

Cornell's alma mater makes reference to its position "Far Above Cayuga's Waters", while that of Ithaca College references "Cayuga's shore".

A tradition at Wells College in Aurora holds that if the lake completely freezes over, classes are canceled (though for only one day). According to Wells College records, this most recently happened in 1979 and the record cold month of February 2015. However, other sources suggest that the only time the entire lake froze over solid end to end in the 20th century was in 1912, when even the deeper Seneca Lake last froze over completely.

Cayuga Lake, like nearby Seneca Lake, is also the site of a phenomenon known as the Guns of the Seneca, mysterious cannon-like booms heard in the surrounding area. Many of these booms may be attributable to bird-scarers, automated cannon-like devices used by farmers to scare birds away from the many vineyards, orchards and crops. There is, however, no proof of this.

Wine
Cayuga Lake is included in the American Viticultural Area with which it shares its name. Established in 1988, the AVA now boasts over a dozen wineries, four distilleries, a cidery, and a meadery.

Columbia University

Columbia University, officially Columbia University in the City of New York, is a private Ivy League research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, it is the oldest institution of higher education in New York and the fifth-oldest in the United States.

Columbia was established as a colonial college by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University.

Columbia is organized into twenty schools, including four undergraduate schools and 16 graduate schools. The university's research efforts include the Lamont–Doherty Earth Observatory, the Goddard Institute for Space Studies, and accelerator laboratories with Big Tech firms such as Amazon and IBM. Columbia is a founding member of the Association of American Universities and was the first school in the United States to grant the MD degree. The university also administers and annually awards the Pulitzer Prize.

Columbia scientists and scholars have played a pivotal role in scientific breakthroughs including brain–computer interface; the laser and maser; nuclear magnetic resonance; the first nuclear pile; the first nuclear fission reaction in the Americas; the first evidence for plate tectonics and continental drift;   and much of the initial research and planning for the Manhattan Project during World War II.

, its alumni, faculty, and staff have included seven of the Founding Fathers of the United States of America; four U.S. presidents; 34 foreign heads of state or government; two secretaries-general of the United Nations; ten justices of the United States Supreme Court; 103 Nobel laureates; 125 National Academy of Sciences members; 53 living billionaires; 23 Olympic medalists; 33 Academy Award winners; and 125 Pulitzer Prize recipients.

18th century
Discussions regarding the founding of a college in the Province of New York began as early as 1704, at which time Colonel Lewis Morris wrote to the Society for the Propagation of the Gospel in Foreign Parts, the missionary arm of the Church of England, persuading the society that New York City was an ideal community in which to establish a college. However, it was not until the founding of the College of New Jersey (renamed Princeton) across the Hudson River in New Jersey that the City of New York seriously considered founding a college. In 1746, an act was passed by the general assembly of New York to raise funds for the foundation of a new college. In 1751, the assembly appointed a commission of ten New York residents, seven of whom were members of the Church of England, to direct the funds accrued by the state lottery towards the foundation of a college.

Classes were initially held in July 1754 and were presided over by the college's first president, Samuel Johnson. Johnson was the only instructor of the college's first class, which consisted of a mere eight students. Instruction was held in a new schoolhouse adjoining Trinity Church, located on what is now lower Broadway in Manhattan. The college was officially founded on October 31, 1754, as King's College by royal charter of George II, making it the oldest institution of higher learning in the State of New York and the fifth oldest in the United States.

In 1763, Johnson was succeeded in the presidency by Myles Cooper, a graduate of The Queen's College, Oxford, and an ardent Tory. In the charged political climate of the American Revolution, his chief opponent in discussions at the college was an undergraduate of the class of 1777, Alexander Hamilton. The Irish anatomist, Samuel Clossy, was appointed professor of natural philosophy in October 1765 and later the college's first professor of anatomy in 1767. The American Revolutionary War broke out in 1776, and was catastrophic for the operation of King's College, which suspended instruction for eight years beginning in 1776 with the arrival of the Continental Army. The suspension continued through the military occupation of New York City by British troops until their departure in 1783. The college's library was looted and its sole building requisitioned for use as a military hospital first by American and then British forces.

After the Revolutionary War, the college turned to the State of New York in order to restore its vitality, promising to make whatever changes to the school's charter the state might demand. The legislature agreed to assist the college, and on May 1, 1784, it passed "an Act for granting certain privileges to the College heretofore called King's College". The Act created a board of regents to oversee the resuscitation of King's College, and, in an effort to demonstrate its support for the new Republic, the legislature stipulated that "the College within the City of New York heretofore called King's College be forever hereafter called and known by the name of Columbia College", a reference to Columbia, an alternative name for America which in turn comes from the name of Christopher Columbus. The Regents finally became aware of the college's defective constitution in February 1787 and appointed a revision committee, which was headed by John Jay and Alexander Hamilton. In April of that same year, a new charter was adopted for the college granted the power to a separate board of 24 trustees.

On May 21, 1787, William Samuel Johnson, the son of Samuel Johnson, was unanimously elected president of Columbia College. Prior to serving at the university, Johnson had participated in the First Continental Congress and been chosen as a delegate to the Constitutional Convention. For a period in the 1790s, with New York City as the federal and state capital and the country under successive Federalist governments, a revived Columbia thrived under the auspices of Federalists such as Hamilton and Jay. President George Washington and Vice President John Adams, in addition to both houses of Congress attended the college's commencement on May 6, 1789, as a tribute of honor to the many alumni of the school who had been involved in the American Revolution.

19th century
In November 1813, the college agreed to incorporate its medical school with The College of Physicians and Surgeons, a new school created by the Regents of New York, forming Columbia University College of Physicians and Surgeons. The college's enrollment, structure, and academics stagnated for the majority of the 19th century, with many of the college presidents doing little to change the way that the college functioned. In 1857, the college moved from the King's College campus at Park Place to a primarily Gothic Revival campus on 49th Street and Madison Avenue, where it remained for the next forty years.

During the last half of the 19th century, under the presidency of Frederick A. P. Barnard, for whom Barnard College is named, the institution rapidly assumed the shape of a modern university. Barnard College was created in 1889 as a response to the university's refusal to accept women. By this time, the college's investments in New York real estate became a primary source of steady income for the school, mainly owing to the city's expanding population.

In 1896, university president Seth Low moved the campus from 49th Street to its present location, a more spacious campus in the developing neighborhood of Morningside Heights. Under the leadership of Low's successor, Nicholas Murray Butler, who served for over four decades, Columbia rapidly became the nation's major institution for research, setting the multiversity model that later universities would adopt. Prior to becoming the president of Columbia University, Butler founded Teachers College, as a school to prepare home economists and manual art teachers for the children of the poor, with philanthropist Grace Hoadley Dodge. Teachers College is currently affiliated as the university's Graduate School of Education.

20th century
In the 1940s, research into the atom by faculty members John R. Dunning, I. I. Rabi, Enrico Fermi and Polykarp Kusch placed Columbia's physics department in the international spotlight after the first nuclear pile was built to start what became the Manhattan Project.

In 1928, Seth Low Junior College was established by Columbia University in order to mitigate the number of Jewish applicants to Columbia College. The college was closed in 1936 due to the adverse effects of the Great Depression and its students were subsequently taught at Morningside Heights, although they did not belong to any college but to the university at large. There was an evening school called University Extension, which taught night classes, for a fee, to anyone willing to attend.

In 1947, the program was reorganized as an undergraduate college and designated the School of General Studies in response to the return of GIs after World War II. In 1995, the School of General Studies was again reorganized as a full-fledged liberal arts college for non-traditional students (those who have had an academic break of one year or more, or are pursuing dual-degrees) and was fully integrated into Columbia's traditional undergraduate curriculum. The same year, the Division of Special Programs, later called the School of Continuing Education and now the School of Professional Studies, was established to reprise the former role of University Extension. While the School of Professional Studies only offered non-degree programs for lifelong learners and high school students in its earliest stages, it now offers degree programs in a diverse range of professional and inter-disciplinary fields.

In the aftermath of World War II, the discipline of international relations became a major scholarly focus of the university, and in response, the School of International and Public Affairs was founded in 1946, drawing upon the resources of the faculties of political science, economics, and history. The Columbia University Bicentennial was celebrated in 1954.

During the 1960s, student activism reached a climax with protests in the spring of 1968, when hundreds of students occupied buildings on campus. The incident forced the resignation of Columbia's president, Grayson Kirk, and the establishment of the University Senate.

Though several schools in the university had admitted women for years, Columbia College first admitted women in the fall of 1983, after a decade of failed negotiations with Barnard College, the all-female institution affiliated with the university, to merge the two schools. Barnard College still remains affiliated with Columbia, and all Barnard graduates are issued diplomas signed by the presidents of Columbia University and Barnard College.

During the late 20th century, the university underwent significant academic, structural, and administrative changes as it developed into a major research university. For much of the 19th century, the university consisted of decentralized and separate faculties specializing in Political Science, Philosophy, and Pure Science. In 1979, these faculties were merged into the Graduate School of Arts and Sciences. In 1991, the faculties of Columbia College, the School of General Studies, the Graduate School of Arts and Sciences, the School of the Arts, and the School of Professional Studies were merged into the Faculty of Arts and Sciences, leading to the academic integration and centralized governance of these schools.

21st century
In 2010, the School of International and Public Affairs, which was previously a part of the Faculty of Arts and Sciences, became an independent faculty.

In fall of 2023, pro-Palestine student activists organized protests in response to the Israel–Hamas war, with counter-protests from pro-Israel activists. On April 17, 2024, Columbia president Minouche Shafik was questioned by the House Committee on Education and the Workforce on the topic of antisemitism on campus. Shafik's comments regarding the student activists sparked renewed protests that same day, leading to what CNN described as a "full-blown crisis" over tensions stemming from a pro-Palestinian campus occupation. In response, the university moved in-person classes online on Monday, April 22.

Columbia University called New York Police Department officers in riot gear to remove those demonstrators who seized Hamilton Hall, dozens of whom were arrested.

Morningside Heights
The majority of Columbia's graduate and undergraduate studies are conducted in the Upper Manhattan neighborhood of Morningside Heights on Seth Low's late-19th century vision of a university campus where all disciplines could be taught at one location. The campus was designed along Beaux-Arts planning principles by the architects McKim, Mead & White. Columbia's main campus occupies more than six city blocks, or 32 acres, in [ Morningside Heights, New York City, a neighborhood that contains a number of academic institutions. The university owns over 7,800 apartments in Morningside Heights, housing faculty, graduate students, and staff. Almost two dozen undergraduate dormitories (purpose-built or converted) are located on campus or in Morningside Heights. Columbia University has an extensive tunnel system, more than a century old, with the oldest portions predating the present campus. Some of these remain accessible to the public, while others have been cordoned off. Butler_Library_-_1000px_-_AC.jpg]] Butler Library is the largest in the Columbia University Libraries system and one of the largest buildings on the campus. Proposed as "South Hall" by the university's former president Nicholas Murray Butler as expansion plans for Low Memorial Library stalled, the new library was funded by Edward Harkness, benefactor of Yale University's residential college system, and designed by his favorite architect, James Gamble Rogers. It was completed in 1934 and renamed for Butler in 1946. The library design is neo-classical in style. Its facade features a row of columns in the Ionic order above which are inscribed the names of great writers, philosophers, and thinkers, most of whom are read by students engaged in the Core Curriculum of Columbia College. , Columbia's library system includes over 15.0 million volumes, making it the eighth largest library system and fifth largest collegiate library system in the United States.

Several buildings on the Morningside Heights campus are listed on the National Register of Historic Places. Low Memorial Library, a National Historic Landmark and the centerpiece of the campus, is listed for its architectural significance. Philosophy Hall is listed as the site of the invention of FM radio. Also listed is Pupin Hall, another National Historic Landmark, which houses the physics and astronomy departments. Here the first experiments on the fission of uranium were conducted by Enrico Fermi. The uranium atom was split there ten days after the world's first atom-splitting in Copenhagen, Denmark. Other buildings listed include Casa Italiana, the Delta Psi, Alpha Chapter building of St. Anthony Hall, Earl Hall, and the buildings of the affiliated Union Theological Seminary. A statue by sculptor Daniel Chester French called Alma Mater is centered on the front steps of Low Memorial Library. Draped in an academic gown, the female figure of Alma Mater wears a crown of laurels and sits on a throne. The scroll-like arms of the throne end in lamps, representing sapientia and doctrina. A book signifying knowledge, balances on her lap, and an owl, the attribute of wisdom, is hidden in the folds of her gown. Her right hand holds a scepter composed of four sprays of wheat, terminating with a crown of King's College which refers to Columbia's origin as a royal charter institution in 1754. A local actress named Mary Lawton was said to have posed for parts of the sculpture. The statue was dedicated on September 23, 1903, as a gift of Mr. & Mrs. Robert Goelet, and was originally covered in golden leaf. During the Columbia University protests of 1968 a bomb damaged the sculpture, but it has since been repaired. The small hidden owl on the sculpture is also the subject of many Columbia legends, the main legend being that the first student in the freshmen class to find the hidden owl on the statue will be valedictorian, and that any subsequent Columbia male who finds it will marry a Barnard student, given that Barnard is a women's college.

"The Steps", alternatively known as "Low Steps" or the "Urban Beach", are a popular meeting area for Columbia students. The term refers to the long series of granite steps leading from the lower part of campus (South Field) to its upper terrace. With a design inspired by the City Beautiful movement, the steps of Low Library provides Columbia University and Barnard College students, faculty, and staff with a comfortable outdoor platform and space for informal gatherings, events, and ceremonies. McKim's classical facade epitomizes late 19th-century new-classical designs, with its columns and portico marking the entrance to an important structure.

Other campuses
In April 2007, the university purchased more than two-thirds of a 17 acre site for a new campus in Manhattanville, an industrial neighborhood to the north of the Morningside Heights campus. Stretching from 125th Street to 133rd Street, Columbia Manhattanville houses buildings for Columbia's Business School, School of International and Public Affairs, Columbia School of the Arts, and the Jerome L. Greene Center for Mind, Brain, and Behavior, where research will occur on neurodegenerative diseases such as Parkinson's and Alzheimer's. The $7 billion expansion plan included demolishing all buildings, except three that are historically significant (the Studebaker Building, Prentis Hall, and the Nash Building), eliminating the existing light industry and storage warehouses, and relocating tenants in 132 apartments. Replacing these buildings created 6.8 e6sqft of space for the university. Community activist groups in West Harlem fought the expansion for reasons ranging from property protection and fair exchange for land, to residents' rights. Subsequent public hearings drew neighborhood opposition. , the State of New York's Empire State Development Corporation approved use of eminent domain, which, through declaration of Manhattanville's "blighted" status, gives governmental bodies the right to appropriate private property for public use. On May 20, 2009, the New York State Public Authorities Control Board approved the Manhanttanville expansion plan.

NewYork-Presbyterian Hospital is affiliated with the medical schools of both Columbia University and Cornell University. According to U.S. News & World Report's "2020–21 Best Hospitals Honor Roll and Medical Specialties Rankings", it is ranked fourth overall and second among university hospitals. Columbia's medical school has a strategic partnership with New York State Psychiatric Institute, and is affiliated with 19 other hospitals in the U.S. and four hospitals in other countries. Health-related schools are located at the Columbia University Medical Center, a 20 acre campus located in the neighborhood of Washington Heights, fifty blocks uptown. Other teaching hospitals affiliated with Columbia through the NewYork-Presbyterian network include the Payne Whitney Clinic in Manhattan, and the Payne Whitney Westchester, a psychiatric institute located in White Plains, New York. On the northern tip of Manhattan island (in the neighborhood of Inwood), Columbia owns the 26 acre Baker Field, which includes the Lawrence A. Wien Stadium as well as facilities for field sports, outdoor track, and tennis. There is a third campus on the west bank of the Hudson River, the 157 acre Lamont–Doherty Earth Observatory and Earth Institute in Palisades, New York. A fourth is the 60 acre Nevis Laboratories in Irvington, New York, for the study of particle and motion physics. A satellite site in Paris holds classes at Reid Hall.

Sustainability
In 2006, the university established the Office of Environmental Stewardship to initiate, coordinate and implement programs to reduce the university's environmental footprint. The U.S. Green Building Council selected the university's Manhattanville plan for the Leadership in Energy and Environmental Design (LEED) Neighborhood Design pilot program. The plan commits to incorporating smart growth, new urbanism and "green" building design principles. Columbia is one of the 2030 Challenge Partners, a group of nine universities in the city of New York that have pledged to reduce their greenhouse emissions by 30% within the next ten years. Columbia University adopts LEED standards for all new construction and major renovations. The university requires a minimum of Silver, but through its design and review process seeks to achieve higher levels. This is especially challenging for lab and research buildings with their intensive energy use; however, the university also uses lab design guidelines that seek to maximize energy efficiency while protecting the safety of researchers.

Every Thursday and Sunday of the month, Columbia hosts a greenmarket where local farmers can sell their produce to residents of the city. In addition, from April to November Hodgson's farm, a local New York gardening center, joins the market bringing a large selection of plants and blooming flowers. The market is one of the many operated at different points throughout the city by the non-profit group GrowNYC. Dining services at Columbia spends 36 percent of its food budget on local products, in addition to serving sustainably harvested seafood and fair trade coffee on campus. Columbia has been rated "B+" by the 2011 College Sustainability Report Card for its environmental and sustainability initiatives. According to the A. W. Kuchler U.S. potential natural vegetation types, Columbia University would have a dominant vegetation type of Appalachian Oak (104) with a dominant vegetation form of Eastern Hardwood Forest (25).

Transportation
Columbia Transportation is the bus service of the university, operated by Academy Bus Lines. The buses are open to all Columbia faculty, students, Dodge Fitness Center members, and anyone else who holds a Columbia ID card. In addition, all TSC students can ride the buses.

In the New York City Subway, the train serves the university at 116th Street-Columbia University. The buses stop on Broadway while the  stops on Amsterdam Avenue.

The main campus is primarily boxed off by the streets of Amsterdam Avenue, Broadway, 114th street, and 120th street, with some buildings, including Barnard College, located just outside the area. The nearest major highway is the Henry Hudson Parkway (NY 9A) to the west of the campus. It is located 3.4 mi south of the George Washington Bridge.

Undergraduate admissions and financial aid

Columbia University received 60,551 applications for the class of 2025 (entering 2021) and a total of around 2,218 were admitted to the two schools for an overall acceptance rate of 3.66%. Columbia is a racially diverse school, with approximately 52% of all students identifying themselves as persons of color. Additionally, 50% of all undergraduates received grants from Columbia. The average grant size awarded to these students is $46,516. In 2015–2016, annual undergraduate tuition at Columbia was $50,526 with a total cost of attendance of $65,860 (including room and board). The college is need-blind for domestic applicants.

Annual gifts, fund-raising, and an increase in spending from the university's endowment have allowed Columbia to extend generous financial aid packages to qualifying students. On April 11, 2007, Columbia University announced a $400 million donation from media billionaire alumnus John Kluge to be used exclusively for undergraduate financial aid. The donation is among the largest single gifts to higher education. , undergraduates from families with incomes as high as $60,000 a year will have the projected cost of attending the university, including room, board, and academic fees, fully paid for by the university. That same year, the university ended loans for incoming and then-current students who were on financial aid, replacing loans that were traditionally part of aid packages with grants from the university. However, this does not apply to international students, transfer students, visiting students, or students in the School of General Studies. In the fall of 2010, admission to Columbia's undergraduate colleges Columbia College and the Fu Foundation School of Engineering and Applied Science (also known as SEAS or Columbia Engineering) began accepting the Common Application. The policy change made Columbia one of the last major academic institutions and the last Ivy League university to switch to the Common Application.

Scholarships are also given to undergraduate students by the admissions committee. Designations include John W. Kluge Scholars, John Jay Scholars, C. Prescott Davis Scholars, Global Scholars, Egleston Scholars, and Science Research Fellows. Named scholars are selected by the admission committee from first-year applicants. According to Columbia, the first four designated scholars "distinguish themselves for their remarkable academic and personal achievements, dynamism, intellectual curiosity, the originality and independence of their thinking, and the diversity that stems from their different cultures and their varied educational experiences".

In 1919, Columbia established a student application process characterized by The New York Times as "the first modern college application". The application required a photograph of the applicant, the maiden name of the applicant's mother, and the applicant's religious background.

Organization
Columbia University is an independent, privately supported, nonsectarian and not-for-profit institution of higher education. Its official corporate name is Trustees of Columbia University in the City of New York.

In 1754, the university's first charter was granted King George II; however, its modern charter was first enacted in 1787 and last amended in 1810 by the New York State Legislature. The university is governed by 24 trustees, customarily including the president, who serves ex officio. The trustees themselves are responsible for choosing their successors. Six of the 24 are nominated from a pool of candidates recommended by the Columbia Alumni Association. Another six are nominated by the board in consultation with the executive committee of the University Senate. The remaining 12, including the president, are nominated by the trustees themselves through their internal processes. The term of office for trustees is six years. Generally, they serve for no more than two consecutive terms. The trustees appoint the president and other senior administrative officers of the university, and review and confirm faculty appointments as required. They determine the university's financial and investment policies, authorize the budget, supervise the endowment, direct the management of the university's real estate and other assets, and otherwise oversee the administration and management of the university.

The University Senate was established by the trustees after a university-wide referendum in 1969. It succeeded to the powers of the University Council, which was created in 1890 as a body of faculty, deans, and other administrators to regulate inter-Faculty affairs and consider issues of university-wide concern. The University Senate is a unicameral body consisting of 107 members drawn from all constituencies of the university. These include the president of the university, the provost, the deans of Columbia College and the Graduate School of Arts and Sciences, all of whom serve ex officio, and five additional representatives, appointed by the president, from the university's administration. The president serves as the Senate's presiding officer. The Senate is charged with reviewing the educational policies, physical development, budget, and external relations of the university. It oversees the welfare and academic freedom of the faculty and the welfare of students.

The president of Columbia University, who is selected by the trustees in consultation with the executive committee of the University Senate and who serves at the trustees' pleasure, is the chief executive officer of the university. Assisting the president in administering the university are the provost, the senior executive vice president, the executive vice president for health and biomedical sciences, several other vice presidents, the general counsel, the secretary of the university, and the deans of the faculties, all of whom are appointed by the trustees on the nomination of the president and serve at their pleasure. Minouche Shafik became the 20th president of Columbia University on July 1, 2023. Columbia has four official undergraduate colleges: Columbia College, the liberal arts college offering the Bachelor of Arts degree; the Fu Foundation School of Engineering and Applied Science (also known as SEAS or Columbia Engineering), the engineering and applied science school offering the Bachelor of Science degree; the School of General Studies, the liberal arts college offering the Bachelor of Arts degree to non-traditional students undertaking full- or part-time study; and Barnard College. Barnard College is a women's liberal arts college and an academic affiliate in which students receive a Bachelor of Arts degree from Columbia University. Their degrees are signed by the presidents of Columbia University and Barnard College. Barnard students are also eligible to cross-register classes that are available through the Barnard Catalogue and alumnae can join the Columbia Alumni Association.

Joint degree programs are available through Union Theological Seminary, the Jewish Theological Seminary of America, and the Juilliard School. Teachers College and Barnard College are official faculties of the university; both colleges' presidents are deans under the university governance structure. The Columbia University Senate includes faculty and student representatives from Teachers College and Barnard College who serve two-year terms; all senators are accorded full voting privileges regarding matters impacting the entire university. Teachers College is an affiliated, financially independent graduate school with their own board of trustees. Pursuant to an affiliation agreement, Columbia is given the authority to confer "degrees and diplomas" to the graduates of Teachers College. The degrees are signed by presidents of Teachers College and Columbia University in a manner analogous to the university's other graduate schools. Columbia's General Studies school also has joint undergraduate programs available through University College London, Sciences Po, City University of Hong Kong, Trinity College Dublin, and the Juilliard School.

The university also has several Columbia Global Centers, in Amman, Beijing, Istanbul, Mumbai, Nairobi, Paris, Rio de Janeiro, Santiago, and Tunis.

International partnerships
Columbia students can study abroad for a semester or a year at partner institutions such as Sciences Po, École des hautes études en sciences sociales (EHESS), École normale supérieure (ENS), Panthéon-Sorbonne University, King's College London, London School of Economics, University College London and the University of Warwick. Select students can study at either the University of Oxford or the University of Cambridge for a year if approved by both Columbia and either Oxford or Cambridge. Columbia also has a dual MA program with the Aga Khan University in London.

It was ranked in the first tier of American research universities, along with Harvard, MIT, and Stanford, in the 2019 report from the Center for Measuring University Performance. Columbia's Graduate School of Architecture, Planning and Preservation was ranked the second most admired graduate program by Architectural Record in 2020.

In 2011, the Mines ParisTech: Professional Ranking of World Universities ranked Columbia third best university for forming CEOs in the US and 12th worldwide.

Controversies
In 2022, Columbia's reporting of metrics used for university ranking was criticized by Professor of Mathematics Michael Thaddeus, who argued key data supporting the ranking was "inaccurate, dubious or highly misleading." Subsequently, U.S. News & World Report "unranked" Columbia from its 2022 list of Best Colleges saying that it could not verify the data submitted by the university. In June 2023, Columbia University announced their undergraduate schools would no longer participate in U.S. News & World Report's rankings, following the lead of its law, medical and nursing schools. A press release cited concerns that such rankings unduly influence applicants and "distill a university's profile into a composite of data categories."

Research
Columbia is classified among "R1: Doctoral Universities – Very high research activity". Columbia was the first North American site where the uranium atom was split. The College of Physicians and Surgeons played a central role in developing the modern understanding of neuroscience with the publication of Principles of Neural Science, described by historian of science Katja Huenther as the "neuroscience 'bible' ". The book was written by a team of Columbia researchers that included Nobel Prize winner Eric Kandel, James H. Schwartz, and Thomas Jessell. Columbia was the birthplace of FM radio and the laser. The first brain-computer interface capable of translating brain signals into speech was developed by neuroengineers at Columbia. The MPEG-2 algorithm of transmitting high quality audio and video over limited bandwidth was developed by Dimitris Anastassiou, a Columbia professor of electrical engineering. Biologist Martin Chalfie was the first to introduce the use of Green Fluorescent Protein (GFP) in labeling cells in intact organisms. Other inventions and products related to Columbia include Sequential Lateral Solidification (SLS) technology for making LCDs, System Management Arts (SMARTS), Session Initiation Protocol (SIP) (which is used for audio, video, chat, instant messaging and whiteboarding), pharmacopeia, Macromodel (software for computational chemistry), a new and better recipe for glass concrete, Blue LEDs, and Beamprop (used in photonics).

Columbia scientists have been credited with about 175 new inventions in the health sciences each year. More than 30 pharmaceutical products based on discoveries and inventions made at Columbia reached the market. These include Remicade (for arthritis), Reopro (for blood clot complications), Xalatan (for glaucoma), Benefix, Latanoprost (a glaucoma treatment), shoulder prosthesis, homocysteine (testing for cardiovascular disease), and Zolinza (for cancer therapy). Columbia Technology Ventures (formerly Science and Technology Ventures),, manages some 600 patents and more than 250 active license agreements. Patent-related deals earned Columbia more than $230 million in the 2006 fiscal year, according to the university, more than any university in the world. Columbia owns many unique research facilities, such as the Columbia Institute for Tele-Information dedicated to telecommunications and the Goddard Institute for Space Studies, which is an astronomical observatory affiliated with NASA.

Military and veteran enrollment
Columbia is a long-standing participant of the United States Department of Veterans Affairs Yellow Ribbon Program, allowing eligible veterans to pursue a Columbia undergraduate degree regardless of socioeconomic status for over 70 years. As a part of the Eisenhower Leader Development Program (ELDP) in partnership with the United States Military Academy at West Point, Columbia is the only school in the Ivy League to offer a graduate degree program in organizational psychology to aid military officers in tactical decision making and strategic management.

Student life
In 2020, Columbia University's student population was 31,455 (8,842 students in undergraduate programs and 22,613 in postgraduate programs), with 45% of the student population identifying themselves as a minority. Twenty-six percent of students at Columbia have family incomes below $60,000. 16% of students at Columbia receive Federal Pell Grants, which mostly go to students whose family incomes are below $40,000. Seventeen percent of students are the first member of their family to attend a four-year college.

On-campus housing is guaranteed for all four years as an undergraduate. Columbia College and the Fu Foundation School of Engineering and Applied Science (also known as SEAS or Columbia Engineering) share housing in the on-campus residence halls. First-year students usually live in one of the large residence halls situated around South Lawn: Carman Hall, Furnald Hall, Hartley Hall, John Jay Hall, or Wallach Hall (originally Livingston Hall). Upperclassmen participate in a room selection process, wherein students can pick to live in a mix of either corridor- or apartment-style housing with their friends. The Columbia University School of General Studies, Barnard College and graduate schools have their own apartment-style housing in the surrounding neighborhood.

Columbia University is home to many fraternities, sororities, and co-educational Greek organizations. Approximately 10–15% of undergraduate students are associated with Greek life. Many Barnard women also join Columbia sororities. There has been a Greek presence on campus since the establishment in 1836 of the Delta chapter of Alpha Delta Phi. The InterGreek Council is the self-governing student organization that provides guidelines and support to its member organizations within each of the three councils at Columbia, the Interfraternity Council, Panhellenic Council, and Multicultural Greek Council. The three council presidents bring their affiliated chapters together once a month to meet as one Greek community. The InterGreek Council meetings provide opportunity for member organizations to learn from each other, work together and advocate for community needs.

Former publications include the Columbia University Forum, a review of literature and cultural affairs distributed for free to alumni.

Broadcasting
Columbia is home to two pioneers in undergraduate campus radio broadcasting, WKCR-FM and CTV. Many undergraduates are also involved with Barnard's radio station, WBAR. WKCR, the student run radio station that broadcasts to the Tri-state area, claims to be the oldest FM radio station in the world, owing to the university's affiliation with Major Edwin Armstrong. The station went operational on July 18, 1939, from a 400-foot antenna tower in Alpine, New Jersey, broadcasting the first FM transmission in the world. Initially, WKCR was not a radio station, but an organization concerned with the technology of radio communications. As membership grew, however, the nascent club turned its efforts to broadcasting. Armstrong helped the students in their early efforts, donating a microphone and turntables when they designed their first makeshift studio in a dorm room. The station has its studios on the second floor of Alfred Lerner Hall on the Morningside campus with its main transmitter tower at 4 Times Square in Midtown Manhattan. Columbia Television (CTV) is the nation's second oldest student television station and the home of CTV News, a weekly live news program produced by undergraduate students.

Debate and Model UN

The society annually administers the Joyce Kilmer Memorial Bad Poetry Contest. The Columbia Parliamentary Debate Team competes in tournaments around the country as part of the American Parliamentary Debate Association, and hosts both high school and college tournaments on Columbia's campus, as well as public debates on issues affecting the university.

The Columbia International Relations Council and Association (CIRCA), oversees Columbia's Model United Nations activities. CIRCA hosts college and high school Model UN conferences, hosts speakers influential in international politics to speak on campus, and trains students from underprivileged schools in New York in Model UN.

Technology and entrepreneurship
Columbia is a top supplier of young engineering entrepreneurs for New York City. Over the past 20 years, graduates of Columbia established over 100 technology companies.

The Columbia University Organization of Rising Entrepreneurs (CORE) was founded in 1999. The student-run group aims to foster entrepreneurship on campus. Each year CORE hosts dozens of events, including talks, #StartupColumbia, a conference and venture competition for $250,000, and Ignite@CU, a weekend for undergrads interested in design, engineering, and entrepreneurship. Notable speakers include Peter Thiel, Jack Dorsey, Alexis Ohanian, Drew Houston, and Mark Cuban. As of 2006, CORE had awarded graduate and undergraduate students over $100,000 in seed capital.

CampusNetwork, an on-campus social networking site called Campus Network that preceded Facebook, was created and popularized by Columbia engineering student Adam Goldberg in 2003. Mark Zuckerberg later asked Goldberg to join him in Palo Alto to work on Facebook, but Goldberg declined the offer. The Fu Foundation School of Engineering and Applied Science offers a minor in Technical Entrepreneurship through its Center for Technology, Innovation, and Community Engagement. SEAS' entrepreneurship activities focus on community building initiatives in New York and worldwide, made possible through partners such as Microsoft Corporation.

On June 14, 2010, Mayor Michael R. Bloomberg launched the NYC Media Lab to promote innovations in New York's media industry. Situated at the New York University Tandon School of Engineering, the lab is a consortium of Columbia University, New York University, and New York City Economic Development Corporation acting to connect companies with universities in new technology research. The Lab is modeled after similar ones at MIT and Stanford, and was established with a $250,000 grant from the New York City Economic Development Corporation.

In 1900, Olympian and Columbia College student Maxie Long set the first official world record in the 400 meters with a time of 47.8 seconds. In 1983, Columbia men's soccer went 18–0 and was ranked first in the nation, but lost to Indiana 1–0 in double overtime in the NCAA championship game; nevertheless, the team went further toward the NCAA title than any Ivy League soccer team in history. The football program unfortunately is best known for its record of futility set during the 1980s: between 1983 and 1988, the team lost 44 games in a row, which is still the record for the NCAA Football Championship Subdivision. The streak was broken on October 8, 1988, with a 16–13 victory over arch-rival Princeton University. That was the Lions' first victory at Wien Stadium, which had been opened during the losing streak and was already four years old. A new tradition has developed with the Liberty Cup. The Liberty Cup is awarded annually to the winner of the football game between Fordham and Columbia Universities, two of the only three NCAA Division I football teams in New York City.

The Varsity Show
The Varsity Show is one of the oldest traditions at Columbia. Founded in 1893 as a fundraiser for the university's fledgling athletic teams, the Varsity Show now draws together the entire Columbia undergraduate community for a series of performances every April.

In particular, Streets of New York, after having been revived three times, opened off-Broadway in 1963 and was awarded a 1964 Drama Desk Award. The Mischief Maker (1903), written by Edgar Allan Woolf and Cassius Freeborn, premiered at Madison Square Garden in 1906 as Mam'zelle Champagne.

Tree Lighting and Yule Log ceremonies
The campus Tree Lighting ceremony was inaugurated in 1998. It celebrates the illumination of the medium-sized trees lining College Walk in front of Kent Hall and Hamilton Hall on the east end and Dodge Hall and Pulitzer Hall on the west, just before finals week in early December. The lights remain on until February 28. Students meet at the sundial for free hot chocolate, performances by a cappella groups, and speeches by the university president and a guest.

Immediately following the College Walk festivities is one of Columbia's older holiday traditions, the lighting of the Yule Log. The Christmas ceremony dates to a period prior to the American Revolutionary War, but lapsed before being revived by President Nicholas Murray Butler in 1910. A troop of students dressed as Continental Army soldiers carry the eponymous log from the sundial to the lounge of John Jay Hall, where it is lit amid the singing of seasonal carols. The Christmas ceremony is accompanied by a reading of A Visit From St. Nicholas by Clement Clarke Moore and Yes, Virginia, There is a Santa Claus by Francis Pharcellus Church.
