bark, silk, wood and leather functioned in a similar way to paper, although they were either much more expensive or heavier. In China, many early works were recorded on long bamboo strips, which were then bound with leather straps or string into books.

People world-wide also carved very important notations into stone or bone, or pressed stamps into wet clay and then dried or fired the tablets to preserve their words. However, writing (and later printing) required a material that was both cheap and lightweight in order to become truly ubiquitous. Paper fit the bill perfectly.

Early paper-makers in China used hemp fibers, which were soaked in water and pounded with a large wooden mallet. The resulting slurry was then poured over a horizontal mold; loosely-woven cloth stretched over a framework of bamboo allowed the water to drip out the bottom or evaporate, leaving behind a flat sheet of dry hemp-fiber paper.

One of the most common formats for early paper was the scroll. A few long pieces of paper were pasted together to form a strip, which was then wrapped around a wooden roller. The other end of the paper was attached to a thin wooden dowel, with a piece of silk cord in the middle to tie the scroll shut.

From its point of origin in China, the idea and technology of paper-making spread throughout Asia.

The Koreans also used rice straw and seaweed, expanding the types of fiber available for paper production. This early adoption of paper fueled the Korean innovations in printing, as well; metal movable type was invented by 1234 CE on the peninsula.

One of the most interesting repercussions of this Arab victory was that the Abbasids captured Chinese artisans - including master paper-makers like Tou Houan - and took them back to the Middle East.

so knowledge of this marvelous new material spread far and wide. Before long, cities from Samarkand (now in Uzbekistan) to Damascus and Cairo had become centers of paper production.

In 1120, the Moors established Europe's first paper mill at Valencia, Spain (then called Xativa). From there, this Chinese invention passed to Italy, Germany, and other parts of Europe. Paper helped spread knowledge, much of which was gleaned from the great Asian culture centers along the Silk Road, that enabled Europe's High Middle Ages.

Venice earned special trading rights with the empire in return for accepting Byzantine sovereignty again. The city grew richer, and independence was gained in 1082. However, they retained trading advantages with Byzantium by offering the use of their, now considerable, navy.

The twelfth century saw Venice and the remainder of the Byzantine Empire engage in a series of trade wars, before the events of the early thirteenth century gave Venice the chance to establish a physical trading empire: Venice had agreed to transport a crusade to the ‘Holy Land,’ but this became stuck when the crusaders couldn’t pay.

Venice then warred with Genoa, a powerful Italian trading rival

In addition, Portuguese sailors had rounded Africa, opening another trading route to the east. Expansion in Italy also backfired when the pope organized the League of Cambrai to challenge Venice, defeating the city. Although the territory was regained, the loss of reputation was immense.

Venetian expansion targeted the Italian mainland with the capture of Vicenza, Verona, Padua, and Udine.

This era, 1420–50, was arguably the high point of Venetian wealth and power. The population even sprang back after the Black Death, which often traveled along trade routes.

Venice’s decline began in 1453, when Constantinople fell to the Ottoman Turks, whose expansion would threaten, and successfully seize, many of Venice’s eastern lands

restricting Genoan trade. Others attacked Venice too, and the empire had to be defended

The Venetian Republic came to an end in 1797, when Napoleon’s French army forced the city to agree to a new, pro-French, ‘democratic’ government; the city was looted of great artworks. Venice was briefly Austrian after a peace treaty with Napoleon, but became French again after the Battle of Austerlitz in 1805, and formed part of the short-lived Kingdom of Italy. The fall of Napoleon from power saw Venice placed back under Austrian rule.

. In the 1860s, Venice became part of the new Kingdom of Italy, where it remains to this day in the new Italian state,

managed to fend off both the French and the British through skillful diplomacy. He adopted many European customs and was intensely interested in European technologies. He also played the British and French off of one another, preserving most of Siam's territory and its independence.

The Ottoman Empire was too large, powerful, and complex for any one European power to simply annex it outright.

the European powers peeled off its territories in northern Africa and southeast Europe by seizing them directly or by encouraging and supplying local independence movements.

the Ottoman government or Sublime Porte had to borrow money from European banks to finance its operations. When it was unable to repay the money it owed to the London and Paris-based banks, they took control of the Ottoman revenue system, seriously infringing on the Porte's sovereignty. Foreign interests also invested heavily in railroad, port, and infrastructure projects, giving them ever more power within the tottering empire. The Ottoman Empire remained self-governing until it fell after World War I, but foreign banks and investors wielded an inordinate amount of power there.

Like the Ottoman Empire, Qing China was too large for any single European power to simply grab. Instead, Britain and France got a foothold through trade

Both Great Britain and Russia hoped to seize Afghanistan as part of their "Great Game" - a competition for land and influence in Central Asia. However, the Afghans had other ideas; they famously "don't like foreigners with guns in their country,

They slaughtered or captured an entire British army

, that gave Britain control of Afghanistan's foreign relations,

This shielded British India from Russian expansionism while leaving Afghanistan more or less independent.

Like Afghanistan, the British and Russians considered Persia an important piece in the Great Game

Russia nibbled away at northern Persian territory

Britain extended its influence into the eastern Persian Balochistan region

Like the Ottomans, the Qajar rulers of Persia had borrowed money from European banks for projects like railroads and other infrastructure improvements, and could not pay back the money.  Britain and Russia agreed without consulting the Persian government that they would split the revenues from Persian customs, fisheries, and other industries to amortize the debts. Persia never became a formal colony, but it temporarily lost control of its revenue stream and much of its territory - a source of bitterness to this

Nepal, Bhutan, Korea, Mongolia, and the Middle Eastern protectorates:

Nepal lost about one-third of its territory to the British East India Company's

However, the Gurkhas fought so well and the land was so rugged that the British decided to leave Nepal alone as a buffer state for British India. The British also began to recruit Gurkhas for their colonial army.

Bhutan, another Himalayan kingdom, also faced invasion by the British East India Company but managed to retain its sovereignty.

they relinquished the land in return for a tribute of five horses and the right to harvest timber on Bhutanese soil. Bhutan and Britain regularly squabbled over their borders until 1947, when the British pulled out of India, but Bhutan's sovereignty was never seriously threatened.

an outbreak erupted in the Yuan Empire and may have hastened the end of Mongol rule over China. Three years later, the disease killed over 90 percent of the Hebei Province's populations

with deaths totaling over 5 million people.

From its origin at the eastern end of the Silk Road, the Black Death rode trade routes west stopping at Central Asian caravansaries and Middle Eastern trade centers and subsequently infected people all across Asia.

"The Land of Darkness," or Central Asia. From there, it spread to China, India, the Caspian Sea and "land of the Uzbeks," and thence to Persia and the Mediterranean.

The Central Asian scourge struck Persia just a few years after it appeared in China — proof if any is needed that the Silk Road was a convenient route of transmission for the deadly bacterium.

Civilization both in the East and the West was visited by a destructive plague which devastated nations and caused populations to vanish

The region's population was slow to recover, in part due to the political disruptions caused by the fall of Mongol rule and the later invasions of Timur (Tamerlane).

In 1335, the Il-Khan (Mongol) ruler of Persia and the Middle East, Abu Said, died of bubonic plague during a war with his northern cousins, the Golden Horde. This signaled the beginning of the end for Mongol rule in the region

He goes on to charge that the Mongol leader "ordered corpses to be placed in catapults and lobbed into the city in hopes that the intolerable stench would kill everyone inside."

This incident is often cited as the first instance of biological warfare in history. However, other contemporary chroniclers make no mention of the putative Black Death catapults.

European observers were fascinated but not too worried when the Black Death struck the western rim of Central Asia and the Middle East

, the holy city of Mecca was hit by the plague, likely brought in by infected pilgrims on the hajj.

It seems more likely, however, that traders from further east brought diseased fleas

It swallowed up many of the good things of civilization and wiped them out... Civilization decreased with the decrease of mankind. Cities and buildings were laid waste, roads and way signs were obliterated, settlements and mansions became empty, dynasties and tribes grew weak. The entire inhabited world changed."

Perhaps the most significant impact that the Black Death had on Asia was that it contributed to the fall of the mighty Mongol Empire. After all, the pandemic started within the Mongol Empire and devastated peoples from all four of the khanates.

The massive population loss and terror caused by the plague destabilized Mongolian governments from the Golden Horde in Russia to the Yuan Dynasty in China. The Mongol ruler of the Ilkhanate Empire in the Middle East died of the disease along with six of his sons.

Although the Pax Mongolica had allowed increased wealth and cultural exchange, through a reopening of the Silk Road, it also allowed this deadly contagion to spread rapidly westward from its origin in western China or eastern Central Asia. As a result, the world's second-largest empire ever crumbled and fell.

During the Enlightenment, however, Europeans developed new standards and tools for mapping, and since they weren’t sure precisely where the lakes, mountains, and cities of Africa were, they began erasing them from popular maps. Many scholarly maps still had more details, but due to the new standards, the European explorers who went to Africa were credited with discovering the mountains, rivers, and kingdoms to which African people guided them.

Once the British Empire abolished slavery in 1833, however, abolitionists turned their efforts against slavery within Africa. In the colonies, the British were also frustrated that former slaves didn’t want to keep working on plantations for very low wages. Soon the British were portraying African men not as brothers, but as lazy idlers or evil slave traders.

At the same time, missionaries began traveling to Africa to bring the word of God. They expected to have their work cut out for them, but when decades later they still had few converts in many areas, they began saying that African people’s hearts were locked in darkness. They were closed off from the saving light of Christianity.

guns gave these men significant power in Africa.

When they abused that power – especially in the Congo -  Europeans blamed the Dark Continent, rather than themselves. Africa, they said, was the that supposedly brought out the savagery in man. 

Race does lie at the heart of this myth, but it not about skin color. The myth of the Dark Continent referred to the savagery Europeans said was endemic to Africa, and even the idea that its lands were unknown came from erasing centuries of pre-colonial history, contact, and travel acro

Our overall goal is that, by around 2030, China will be among the major space powers of the world

China was late to the space race

But in the decades since, China has pumped billions of dollars and other resources into research and training

China has staged a spacewalk, landed a rover on the moon and launched a space lab that it hopes paves the way for a 20-ton space station

He said other plans include sending probes to Jupiter and its moons

China is still studying the possibility of sending a man to the moon, but focusing on robotic lunar missions for now, including making the first soft landing on the far side of the moon around 2018

He also emphasized China's increasing cooperation with other international space agencies -- with NASA being the exception

the U.S. Congress has prohibited NASA from working with China because of national security concerns

NASA should be focused primarily on deep space activities rather than Earth-centric work that is better handled by other agencies," wrote Robert Walker and Peter Navarro

While the American government's space program has suffered from under-investment, both China and Russia continue to move briskly forward with military-focused initiatives," they added. "Each continues to develop weapons explicitly designed... to 'deny, degrade, deceive, disrupt, or destroy' America's eyes and ears in space

Chinese officials on Tuesday reiterated the country's "peaceful motives" behind its space exploration and utilization, but many have pointed to Walker and Navarro's article as a sign that potential U.S.-China collaboration in space would be unlikely

Modern Egyptians, by comparison, share much more DNA with sub-Saharan populations.

The findings have turned years of theory on its head

Heat and high humidity in tombs, paired with some of the chemicals involved in mummification, all contribute to DNA degradation

They found that the sample set showed a strong connection with a cluster of ancient non-African populations based east of the Mediterranean Sea

This is not just the DNA of one person. It's the DNA of the parents, grandparents, grandparents' parents, grand-grand-grandparents' parents and so forth

Strict social structures and legal incentives to marry along ethnic lines within these communities may have played a part in the Egyptians' genetic stasis

A lot of people has assumed foreign invaders ... brought a lot of genetic ancestry into the region," Krause said. "People expected that through time, Egypt would become more European, but we see the exact opposite

Modern Egyptians were found to "inherit 8% more ancestry from African ancestors" than the mummies studied. The paper cites increased mobility along the Nile, increased long-distance commerce and the era of the trans-Saharan slave trade as potential reasons why

The team's findings do come with one obvious caveat: "All our genetic data (was) obtained from a single site in Middle Egypt and may not be representative for all of ancient Egypt

North Korea has also been assessed as possessing a miniaturized nuclear warhead that can be fitted onto an ICBM

it stunned the world by testing what it called a hydrogen bomb, far more powerful than anything the U.S. dropped on Hiroshima or Nagasaki

It used to be that they emphasized the importance of the military in their politics. Now they’ve begun de-emphasizing that and they’ve begun to emphasize the role of scientists in society both for advancing their economy and, even more than that, for advancing their nuclear weapons and missile technology

Kim, like his father Kim Jong Il, “threatened these scientists with their lives if they don’t make progress. That can be a very powerful motivator

The fact that they are willing to test missiles so frequently suggests they are not really worried about suppl

There’s evidence to suggest that North Korea is, in fact, accelerating its push toward the domestic manufacturing of parts needed for its missile and nuclear programs, turning slowly away from the international black market on which it had traditionally relied

That’s not to say that North Korea’s missile and nuclear technology is state-of-the-art. Many of the designs date back to the Cold War, when the North received nuclear technology from the Soviet Union. Over the years, it acquired weapons technology from China, Iran, Pakistan, and others, and through what can only be described as perseverance cobbled together successful programs

they are willing to have higher tolerances for failure and for less reliability.” That, ultimately, might be North Korea’s biggest advantage in the current standoff with the U.S. and its allies

Narang pointed out that the probability that North Korea is able to deliver a nuclear warhead over San Francisco, or Chicago, or a city on the U.S. East Coast, is not 100 percent—because its technology is not yet that accurate. “But to deter the United States or really induce risk, what percentage is necessary before you cause Washington to have some pause: Is 5 percent acceptable? Are you willing to lose 5,000 to 50,000 Americans, on average? Probably not, right?

The larger the warhead, the less accurate it needs to be

Most of what we know about Genghis Khan’s childhood comes from “The Secret History of the Mongols,” the oldest known work of Mongolian history and literature

Temujin’s own clan then deserted him, his mother and his six siblings

Shortly thereafter, Temujin killed his older half-brother and took over as head of the poverty-stricken household

life for Temujin was violent and unpredictable

Going against custom, Temujin put competent allies rather than relatives in key positions and executed the leaders of enemy tribes while incorporating the remaining members into his clan

Though Temujin was an animist, his followers included Christians, Muslims and Buddhists

Genghis Khan ruled over some 1 million people

He also forbade the selling and kidnapping of women, banned the enslavement of any Mongol and made livestock theft punishable by death. Moreover, Genghis Khan ordered the adoption of a writing system, conducted a regular census, granted diplomatic immunity to foreign ambassadors and allowed freedom of religion well before that idea caught on elsewhere

In early 1227 a horse threw Genghis Khan to the ground, causing internal injuries. He pressed on with the campaign, but his health never recovered

He died on August 18, 1227, just before the Xi Xia were crushed

Genghis Khan conquered more than twice as much land as any other person in history, bringing Eastern and Western civilizations into contact in the process. His descendants, including Ogodei and Khubilai, were also prolific conquerors, taking control of Eastern Europe, the Middle East and the rest of China, among other places. The Mongols even invaded Japan and Java before their empire broke apart in the 14th century
