Sumerian culture disappeared around 4,000 years ago, and the Sumerian language went extinct soon after that.

geological records point to a long period of drier weather in the Middle East around 4,200 years ago, Konfirst said. The Red Sea and the Dead Sea had increased evaporation; water levels dropped at Lake Van in Turkey, and cores from marine sediments around that period indicate increased dust in the environment.

Around the same time, 74 percent of the ancient Mesopotamian settlements were abandoned, according to a 2006 study of an archaeological site called Tell Leilan in Syria. The populated area also shrank by 93 percent, he said.

great drought, two waves of marauding nomads descended upon the region, sacking the capital city of Ur. After around 2000 B.C., ancient Sumerian gradually died off as a spoken language in the region. For the next 2,000 years, the tongue lingered on as a dead written language, similar to Latin in the Middle Ages, but has been completely extinct since then, Konfirst said.

prevent patients from examining their own genetic information” and “made it impossible to obtain second opinions.”

he legal question for the justices is whether isolated genes are “products of nature” that may not be patented or “human-made inventions” eligible for patent protection.

“The isolated DNA molecules before us are not found in nature,” wrote Judge Alan D. Lourie, who was in the majority. “They are obtained in the laboratory and are man-made, the product of human ingenuity.”

“I couldn’t tolerate knowing something was fake and not doing something about it,” he told me. “Everything loses meaning. What’s the point of writing a paper, fighting very hard to get it published, going to conferences?”

Simonsohn stressed that there’s a world of difference between data techniques that generate false positives, and fraud, but he said some academic psychologists have, until recently, been dangerously indifferent to both. Outright fraud is probably rare. Data manipulation is undoubtedly more common—and surely extends to other subjects dependent on statistical study, including biomedicine. Worse, sloppy statistics are “like steroids in baseball”: Throughout the affected fields, researchers who are too intellectually honest to use these tricks will publish less, and may perish. Meanwhile, the less fastidious flourish.

The photo was taken by Jennifer Foster, a civilian communications director for the Pinal County Sheriff’s Office in Arizona. She said the moment resonated for personal reasons: She remembered as a young girl seeing her father, a 32-year veteran of the Phoenix police force, buy food for a homeless man. “He squatted down, just like this officer,” she said.

We don’t even really know what a conscience is, but somebody’s going to have to program one nonetheless.

s code-breaking and communications interception unit in Gloucestershire, agreed to try to crack the code. But on Friday the secretive organization acknowledged that it had been unable to do so.

“Without access to the relevant code books and details of any additional encryption used, it will remain impossible to decrypt,” the Government Communications Headquarters said in a news release.

Mr. Martin said he was skeptical of the idea that the agency had been unable to crack the code. “I think there’s something about that message that is either sensitive or does not reflect well” on British special forces operating behind enemy lines in wartime France, he said in a telephone interview. “I’m convinced that it’s an important message and a secret message.”

every time some kind of calamity has come into my life, I and everyone around me have responded with activity, unexpected strength, even an all but unnatural calm.

It’s only when we’re living in the future, the realm of “what if,” that we brilliantly incapacitate ourselves.

Let's consider a case in which Ulfelder argues there is insufficient data to render a prediction -- North Korea. There is no official data on North Korean GDP, so what can we do? It turns out that the same data science approaches that were used to aggregate polls have other uses as well. One is the imputation of missing data. Yes, even when it is all missing. The basic idea is to use the general correlations among data that you do have to provide an aggregate way of estimating information that we don't have.

In 2012 there were two types of models: one type based on fundamentals such as economic growth and unemployment and another based on public opinion surveys

As it turned out, in this month's election public opinion polls were considerably more precise than the fundamentals. The fundamentals were not always providing bad predictions, but better is better.

There is a tradition in world politics to go either back until the Congress of Vienna (when there were fewer than two dozen independent countries) or to the early 1950s after the end of the Second World War. But in reality, there is no need to do this for most studies.

Ulfelder tells us that "when it comes to predicting major political crises like wars, coups, and popular uprisings, there are many plausible predictors for which we don't have any data at all, and much of what we do have is too sparse or too noisy to incorporate into carefully designed forecasting models." But this is true only for the old style of models based on annual data for countries. If we are willing to face data that are collected in rhythm with the phenomena we are studying, this is not the case

With greater accuracy, for example, marketers can comb large databases of consumer behavior to get more precise information on buying habits. And improvements in facial recognition are likely to make surveillance technology cheaper and more commonplace.

Modern artificial neural networks are composed of an array of software components, divided into inputs, hidden layers and outputs. The arrays can be “trained” by repeated exposures to recognize patterns like images or sounds.

“The point about this approach is that it scales beautifully. Basically you just need to keep making it bigger and faster, and it will get better. There’s no looking back now.”
