August 13 is the 225th day of the year (226th in leap years) in the Gregorian calendar. There are 140 days remaining until the end of the year.

On this day in 1521, the Aztec capital, Tenochtitlan falls to Cortes:

After a three-month siege, Spanish forces under Hernan Cortes capture Tenochtitlan, the capital of the Aztec empire. Cortes’ men leveled the city and captured Cuauhtemoc, the Aztec emperor.

Tenochtitlan was founded in 1325 A.D. by a wandering tribe of hunters and gatherers on islands in Lake Texcoco, near the present site of Mexico City. In only one century, this civilization grew into the Aztec empire, largely because of its advanced system of agriculture. The empire came to dominate central Mexico and by the ascendance of Montezuma II in 1502 had reached its greatest extent, extending as far south as perhaps modern-day Nicaragua. At the time, the empire was held together primarily by Aztec military strength, and Montezuma II set about establishing a bureaucracy, creating provinces that would pay tribute to the imperial capital of Tenochtitlan. The conquered peoples resented the Aztec demands for tribute and victims for the religious sacrifices, but the Aztec military kept rebellion at bay.

After the conquest

Cortes subsequently directed the systematic destruction and leveling of the city and its rebuilding, despite opposition, with a central area designated for Spanish use (the traza). The outer Indian section, now dubbed San Juan Tenochtitlan, continued to be governed by the previous indigenous elite and was divided into the same subdivisions as before.

Ruins

Some of the remaining ruins of Tenochtitlan’s main temple, the Templo Mayor, were uncovered during the construction of a metro line in the 1970s. A small portion has been excavated and is now open to visitors. Mexico City’s Zócalo, the Plaza de la Constitución, is located at the location of Tenochtitlan’s original central plaza and market, and many of the original calzadas still correspond to modern streets in the city. The Aztec sun stone was located in the ruins. This stone is 4 meters in diameter and weighs over 20 tonnes. It was once located half way up the great pyramid. This sculpture was made around 1470 CE under the rule of King Axayacatl, the predecessor of Tizoc, and is said to tell the Aztec history and prophecy for the future.

Medical ethicist Harriet Washington explains why most pharmaceuticals companies decline to produce drugs for the developing world yet use it for clinical testing

The awful ethical questions at the center of the Ebola emergency

By Julia Bellus, Vox

The Ebola outbreak in Africa has confronted ethicists and health officials with a terrible dilemma: when a limited amount of an experimental treatment exists, who should get access first?

There are currently no Ebola treatments on the market. But in this deadliest Ebola outbreak in history, two Americans missionaries received an experimental Ebola drug called ZMapp after getting the disease in Liberia.

Now, infectious disease experts around the world are proclaiming that African Ebola victims should have the same right. In response, both the Obama administration and the World Health Organization set-up expert groups to weigh the moral debates around the more widespread use of untested drugs in what has now been deemed an international health crisis.

To make sense of the thorny problems at the heart of this outbreak’s morality crisis, we called medical ethicists and doctors. Here are the four questions they say they are grappling with.

1) Is it okay to skip the drug testing pathway in a crisis? [..]

2) Why did Americans get an experimental drug while hundreds of Africans die of Ebola? [..]

3) What if the Ebola drug doesn’t work? [..]

4) Who should fund access to Ebola medicines?

These are the questions that try the oath that every doctor takes, Do No Harm.

August 12 is the 224th day of the year (225th in leap years) in the Gregorian calendar. There are 141 days remaining until the end of the year.

It is the peak of the Perseid meteor shower. It is also known as the “Glorious Twelfth” in the UK, as it marks the traditional start of the grouse shooting season.

On this day in 1990, fossil hunter Susan Hendrickson discovers three huge bones jutting out of a cliff near Faith, South Dakota. They turn out to be part of the largest-ever Tyrannosaurus rex skeleton ever discovered, a 65 million-year-old specimen dubbed Sue, after its discoverer.

Amazingly, Sue’s skeleton was over 90 percent complete, and the bones were extremely well-preserved. Hendrickson’s employer, the Black Hills Institute of Geological Research, paid $5,000 to the land owner, Maurice Williams, for the right to excavate the dinosaur skeleton, which was cleaned and transported to the company headquarters in Hill City. The institute’s president, Peter Larson, announced plans to build a non-profit museum to display Sue along with other fossils of the Cretaceous period.

Preparation and display

The Field Museum hired a specialized moving company, with experience in transporting delicate items, to move the bones to Chicago. The truck arrived at the museum in October 1997. Two new research laboratories funded by McDonalds were created and staffed by Field Museum preparators whose job was to slowly and carefully remove all the rock, or “matrix” from the bones. One preparation lab was at Field Museum itself, the other was at the newly opened Animal Kingdom in Disney World in Orlando. Millions of visitors observed the preparation of Sue’s bones through glass windows in both labs. Footage of the work was also put on the museum’s website. Several of the fossil’s bones had never been discovered, so preparators produced models of the missing bones from plastic to complete the exhibit. The modeled bones were colored in a reddish hue so that visitors could observe which bones were real and which bones were plastic. The preparators also poured molds of each bone. All the molds were sent to a company outside Toronto to be cast in hollow plastic. Field Museum kept one set of disarticulated casts in its research collection. The other sets were incorporated into mounted cast skeletons. One set of the casts was sent to Disney’s Animal Kingdom in Florida to be presented for public display. Two other mounted casts were placed into a traveling tour that was sponsored by the McDonald’s Corporation.

Once the preparators finished removing the matrix from each bone, it was sent to the museum’s photographer who made high-quality photographs. From there, the museum’s paleontologists began the study of the skeleton. In addition to photographing and studying each bone, the research staff also arranged for CT scanning of select bones. The skull was too large to fit into a medical CT scanner, so Boeing’s Rocketdyne laboratory in California agreed to let the museum use their CT scanner that was normally used to inspect space shuttle parts.

Bone damage

Close examination of the bones revealed that Sue was 28 years old when she died, making her the oldest T. rex known. During her life this carnivore received several injuries and suffered from numerous pathologies. An injury to the right shoulder region of Sue resulted in a damaged shoulder blade, a torn tendon in the right arm, and three broken ribs. This damage subsequently healed (though one rib healed into two separate pieces), indicating Sue survived the incident. The left fibula is twice the diameter of the right one, likely a result of infection. Original reports of this bone being broken were contradicted by the CT scans which showed no fracture. Multiple holes in the front of the skull were originally thought to be bite marks by some, but subsequent study found these to be areas of infection instead, possibly from an infestation of an ancestral form of Trichomonas gallinae, a protozoan parasite that infests birds. Damage to the back end of the skull was interpreted early on as a fatal bite wound. Subsequent study by Field Museum paleontologists found no bite marks. The distortion and breakage seen in some of the bones in the back of the skull was likely caused by post-mortem trampling. Some of the tail vertebra are fused in a pattern typical of arthritis due to injury. The animal is also believed to have suffered from gout. In addition, there is extra bone in some of the tail vertebrae likely caused by the stresses brought on by Sue’s great size. Sue did not die as a result of any of these injuries; her cause of death is not known.

Display

After the bones were prepared, photographed and studied, they were sent to New Jersey where work began on making the mount. This work consists of bending steel to support each bone safely and to display the entire skeleton articulated as it was in life. The real skull was not incorporated into the mount as subsequent study would be difficult with the head 13 feet off the ground. Parts of the skull had been crushed and broken, and thus appeared distorted. The museum made a cast of the skull, and altered this cast to remove the distortions, thus approximating what the original undistorted skull may have looked like. The cast skull was also lighter, allowing it to be displayed on the mount without the use of a steel upright under the head. The original skull is exhibited in a case that can be opened to allow researchers access for study. When the whole skeleton was assembled, it was forty feet (twelve meters) long from nose to tail, and twelve feet (four meters) tall at the hips.

August 11 is the 223rd day of the year (224th in leap years) in the Gregorian calendar. There are 142 days remaining until the end of the year.

On this day in 1934, the first Federal prisoners arrived at Alcatraz.

A group of federal prisoners classified as “most dangerous” arrives at Alcatraz Island, a 22-acre rocky outcrop situated 1.5 miles offshore in San Francisco Bay. The convicts–the first civilian prisoners to be housed in the new high-security penitentiary–joined a few dozen military prisoners left over from the island’s days as a U.S. military prison.

Alcatraz was an uninhabited seabird haven when it was explored by Spanish Lieutenant Juan Manuel de Ayala in 1775. He named it Isla de los Alcatraces, or “Island of the Pelicans.” Fortified by the Spanish, Alcatraz was sold to the United States in 1849. In 1854, it had the distinction of housing the first lighthouse on the coast of California. Beginning in 1859, a U.S. Army detachment was garrisoned there, and from 1868 Alcatraz was used to house military criminals. In addition to recalcitrant U.S. soldiers, prisoners included rebellious Indian scouts, American soldiers fighting in the Philippines who had deserted to the Filipino cause, and Chinese civilians who resisted the U.S. Army during the Boxer Rebellion. In 1907, Alcatraz was designated the Pacific Branch of the United States Military Prison.

In 1934, Alcatraz was fortified into a high-security federal penitentiary designed to hold the most dangerous prisoners in the U.S. penal system, especially those with a penchant for escape attempts. The first shipment of civilian prisoners arrived on August 11, 1934. Later that month, more shiploads arrived, featuring, among other convicts, infamous mobster Al Capone. In September, George “Machine Gun” Kelly, another luminary of organized crime, landed on Alcatraz.

By decision of Attorney General Robert F. Kennedy, the penitentiary was closed on March 21, 1963. It was closed because it was far more expensive to operate than other prisons (nearly $10 per prisoner per day, as opposed to $3 per prisoner per day at Atlanta), half a century of salt water saturation  had severely eroded the buildings, and the bay was being badly polluted by the sewage from the approximately 250 inmates and 60 Bureau of Prisons families on the island. The United States Penitentiary in Marion, Illinois, a traditional land-bound prison, opened that same year to serve as a replacement for Alcatraz.

The entire Alcatraz Island was listed on the National Register of Historic Places in 1976, and was further declared a National Historic Landmark in 1986. In 1993, the National Park Service published a plan entitled Alcatraz Development Concept and Environmental Assessment.  This plan, approved in 1980, doubled the amount of Alcatraz accessible to the public to enable visitors to enjoy its scenery and bird, marine, and animal life, such as the California slender salamander.

Today American Indian groups such as the International Indian Treaty Council hold ceremonies on the island, most notably, their “Sunrise Gatherings” every Columbus and Thanksgiving Day.

Tonight’s Full Moon is the fourth Super Moon of the 2014 and in case you miss it, you’ll have another chance on September 9. A “super moon” occurs when the moon is new or full “at or near its closest approach to Earth in a given orbit.” Tonight’s moon is at its closest for the year, only 221,765 miles from Earth. Because of its close proximity, tides will be higher than usual, which could cause flooding in some low lying coastal areas. The National Weather Service has issues a coastal flood warning for the eastern seaboard extending from parts of New York City down to Delaware

The uniqueness of this Super Moon is that occurs in conjunction with the first night of Perseid Meteor showers:

The Perseids are a prolific meteor shower associated with the comet Swift-Tuttle. The Perseids are so-called because the point from which they appear to come, called the radiant, lies in the constellation Perseus. The name derives in part from the word Perseides, a term found in Greek mythology referring to the sons of Perseus.

The stream of debris is called the Perseid cloud and stretches along the orbit of the comet Swift-Tuttle. The cloud consists of particles ejected by the comet as it travels on its 133-year orbit. Most of the particles have been part of the cloud for around a thousand years. However, there is also a relatively young filament of dust in the stream that was pulled off the comet in 1865, which can give an early mini-peak the day before the maximum shower. [..]

The shower is visible from mid-July each year, with the peak in activity between 9 and 14 August, depending on the particular location of the stream. During the peak, the rate of meteors reaches 60 or more per hour. They can be seen all across the sky; but, because of the path of Swift-Tuttle’s orbit, Perseids are primarily visible in the northern hemisphere. As with many meteor showers, the visible rate is greatest in the pre-dawn hours, since the side of the Earth nearest to turning into the sun scoops up more meteors as the Earth moves through space. Most Perseids disappear while at heights above 80 kilometres (50 mi).

This year the showers will peak around dawn on on Monday, Tuesday and Wednesday. However, they may be hard to see because of the brightness of the super moon

Your best views are between midnight and a few hours before sunrise (around 6:30 a.m.) as Earth rotates into the stream of debris left behind by comet 109P/Swift-Tuttle. The view improves as the moon sets around 3 a.m. Wednesday morning. The moon will set about an hour later each subsequent day.

Beginning Monday, your best chances are at a more family friendly evening time from shortly after sunset (around 8:45 p.m.) through moonrise about an hour later. The moon also rises about an hour later each subsequent evening, giving more opportunity to see meteors before the nearly full moon washes out the sky. Also take a moment to look low on the southwest horizon for Saturn and just below and to the right for Mars.

August 10 is the 222nd day of the year (223rd in leap years) in the Gregorian calendar. There are 143 days remaining until the end of the year.

The term ‘the 10th of August’ is widely used by historians as a shorthand for the Storming of the Tuileries Palace on the 10th of August, 1792, the effective end of the French monarchy until it is restored in 1814.

On this day in  1846, Smithsonian Institution was created. After a decade of debate about how best to spend a bequest left to America from an obscure English scientist, President James K. Polk signs the Smithsonian Institution Act into law.

In 1829, James Smithson died in Italy, leaving behind a will with a peculiar footnote. In the event that his only nephew died without any heirs, Smithson decreed that the whole of his estate would go to “the United States of America, to found at Washington, under the name of the Smithsonian Institution, an Establishment for the increase and diffusion of knowledge.” Smithson’s curious bequest to a country that he had never visited aroused significant attention on both sides of the Atlantic.

After the nephew died without heirs in 1835, President Andrew Jackson informed Congress of the bequest, which amounted to 104,960 gold sovereigns, or US$500,000 ($10,100,997 in 2008 U.S. dollars after inflation). The money, however, was invested in shaky state bonds that quickly defaulted. After heated debate in Congress, former President John Quincy Adams successfully argued to restore the lost funds with interest.  Congress also debated whether the federal government had the authority to accept the gift. Congress ultimately accepted the legacy bequeathed to the nation and pledged the faith of the United States to the charitable trust July 1, 1836.

Eight years later, Congress passed an act establishing the Smithsonian Institution, a hybrid public/private partnership, and the act was signed into law on August 10, 1846 by James Polk. (See 20 U.S.C. § 41 (Ch. 178, Sec. 1, 9 Stat. 102).) The bill was drafted by Indiana Democratic Congressman Robert Dale Owen, a Socialist and son of Robert Owen, the father of the cooperative movement.

August 9 is the 221st day of the year (222nd in leap years) in the Gregorian calendar. There are 144 days remaining until the end of the year.

On this day in 1974, one day after the resignation of President Richard M. Nixon, Gerald R. Ford is sworn in as president, making him the first man to assume the presidency upon his predecessor’s resignation. He was also the first non-elected vice president and non-elected president, which made his ascendance to the presidency all the more unique.

Gerald Rudolph Ford, Jr. (born Leslie Lynch King, Jr.; July 14, 1913 – December 26, 2006) was the 38th President of the United States, serving from 1974 to 1977, and the 40th Vice President of the United States serving from 1973 to 1974. As the first person appointed to the vice-presidency under the terms of the 25th Amendment, when he became President upon Richard Nixon’s  resignation on August 9, 1974, he also became the only President of the United States who was elected neither President nor Vice-President.

Before ascending to the vice-presidency, Ford served nearly 25 years as Representative from Michigan’s 5th congressional district, eight of them as the Republican Minority Leader.

As President, Ford signed the Helsinki Accords, marking a move toward detente in the Cold War. With the conquest of South Vietnam by North Vietnam nine months into his presidency, US involvement in Vietnam essentially ended. Domestically, Ford presided over what was then the worst economy since the Great Depression, with growing inflation and a recession during his tenure. One of his more controversial acts was to grant a presidential pardon to President Richard Nixon for his role in the Watergate scandal. During Ford’s incumbency, foreign policy was characterized in procedural terms by the increased role Congress began to play, and by the corresponding curb on the powers of the President. In 1976, Ford narrowly defeated Ronald Reagan for the Republican nomination, but ultimately lost the presidential election to Democrat Jimmy Carter.

Following his years as president, Ford remained active in the Republican Party. After experiencing health problems and being admitted to the hospital four times in 2006, Ford died in his home on December 26, 2006. He lived longer than any other U.S. president, dying at the age of 93 years and 165 days.

August 8 is the 220th day of the year (221st in leap years) in the Gregorian calendar. There are 145 days remaining until the end of the year.

On this day in 1974, Richard M. Nixon becomes the first President to resign.

In an evening televised address, President Richard M. Nixon announces his intention to become the first president in American history to resign. With impeachment proceedings underway against him for his involvement in the Watergate affair, Nixon was finally bowing to pressure from the public and Congress to leave the White House. “By taking this action,” he said in a solemn address from the Oval Office, “I hope that I will have hastened the start of the process of healing which is so desperately needed in America.”

Just before noon the next day, Nixon officially ended his term as the 37th president of the United States. Before departing with his family in a helicopter from the White House lawn, he smiled farewell and enigmatically raised his arms in a victory or peace salute. The helicopter door was then closed, and the Nixon family began their journey home to San Clemente, California. Minutes later, Vice President Gerald R. Ford was sworn in as the 38th president of the United States in the East Room of the White House. After taking the oath of office, President Ford spoke to the nation in a television address, declaring, “My fellow Americans, our long national nightmare is over.” He later pardoned Nixon for any crimes he may have committed while in office, explaining that he wanted to end the national divisions created by the Watergate scandal.

August 7 is the 219th day of the year (220th in leap years) in the Gregorian calendar. There are 146 days remaining until the end of the year.

The Northern Hemisphere is considered to be halfway through its summer and the Southern Hemisphere half way through its winter on this day.

On this day in 1947, Kon-Tiki, a balsa wood raft captained by Norwegian anthropologist Thor Heyerdahl, completes a 4,300-mile, 101-day journey from Peru to Raroia in the Tuamotu Archipelago, near Tahiti. Heyerdahl wanted to prove his theory that prehistoric South Americans could have colonized the Polynesian islands by drifting on ocean currents.

Heyerdahl and his five-person crew set sail from Callao, Peru, on the 40-square-foot Kon-Tiki on April 28, 1947. The Kon-Tiki, named for a mythical white chieftain, was made of indigenous materials and designed to resemble rafts of early South American Indians. While crossing the Pacific, the sailors encountered storms, sharks and whales, before finally washing ashore at Raroia. Heyerdahl, born in Larvik, Norway, on October 6, 1914, believed that Polynesia’s earliest inhabitants had come from South America, a theory that conflicted with popular scholarly opinion that the original settlers arrived from Asia. Even after his successful voyage, anthropologists and historians continued to discredit Heyerdahl’s belief. However, his journey captivated the public and he wrote a book about the experience that became an international bestseller and was translated into 65 languages. Heyerdahl also produced a documentary about the trip that won an Academy Award in 1951.
