Polls show a gradual improvement in perceptions of Stalin, who led the Soviet Union from the late 1920s until his death in 1953. A survey released on March 1 by the Levada Center, a research organization based in Moscow, found that 40 percent of Russians thought the Stalin era brought “more good than bad,” up from 27 percent in 2012. In an annual Levada survey published in January 2015, a majority of Russians (52 percent) said Stalin “probably” or “definitely” played a positive role in the country.

My sister is the greatest blessing in my life. My parents and I were at the hospital when her birth mother went into labor, so she has been with us for her entire life. My parents never told her that she was adopted, and they asked me not to say anything. They planned on telling her when she was old enough to understand, but they kept putting it off. They know that I believe they have done her a serious disservice.

The question is more complicated than it seems.

Self-operating machines are permeating every dimension of society, so that humans find themselves interacting more frequently with robots than ever before—often without even realizing it. The human-machine relationship is rapidly evolving as a result. Humanity, and what it means to be a human, will be defined in part by the machines people design.

A top Australian university has rejected claims it is trying to rewrite the nation's colonial history.Students are being encouraged to use the term "invaded" rather than "settled" or "discovered", and avoid the word "Aborigines".The University of New South Wales (UNSW) Indigenous Terminology guide states that Australia was "invaded, occupied and colonised".But UNSW says it does not mandate what language can and cannot be used.

“It is clear to us that Russia will protest,” Kaminski said. “The Kremlin’s diplomats react very violently every time a Soviet monument is removed.”He adds that the issue needs to be resolved quickly, so as not to allow time for “provocation” from Russia.The INR’s initiatives have often divided Russian and Polish opinion, most recently with the launch of a board game modeled on Monopoly that shows the difficulties of the Communist-era economy. The INR-designed game has been a bestseller in Poland and elsewhere. But Russia banned the game earlier this month after it failed to convince the creators to remove all historical references to Communism and turn it into a board game about shopping.

Public frustration with policing has led to calls nationwide for more cameras worn by officers. But what do those cameras actually reveal?

Why do we discriminate? The big factor isn’t overt racism. Rather, it seems to be unconscious bias among whites who believe in equality but act in ways that perpetuate inequality.

That’s why it’s so important for whites to engage in these uncomfortable discussions of race, because we are (unintentionally) so much a part of the problem. It’s not that we’re evil, but that we’re human. The challenge is to recognize that unconscious bias afflicts us all — but that we just may be able to overcome it if we face it.

Graphs can be as manipulative as words. Using tricks such as cutting axes, rescaling things, changing data from positive to negative, etc. Sometimes putting zero on the y-axis is wrong. So to be sure that you are communicating the right things, you need to evaluate the message that people are taking away. There are no absolute rules. It all depends on what you want to communicate.

The bottom line is that humans are very bad at understanding probability. Everyone finds it difficult, even I do. We just have to get better at it. We need to learn to spot when we are being manipulated.

A Swiss secondary school has caused uproar by allowing two Muslim boys not to shake the hand of women teachers - a common greeting in Swiss schools.The boys had told the school in the small, northern town of Therwil it was against their faith to touch a woman outside their family.Justice Minister Simonetta Sommaruga said shaking hands was part of Swiss culture and daily life.A local teachers' union said the exemption discriminated against women.

A group of organizations, including Microsoft and the Rembrandthuis museum, have collaborated to produce a new painting by Rembrandt. Or rather, "by" Rembrandt. The team wrote software that analyzed the Dutch master's entire catalog of paintings and used the data to create a 3D-printed Rembrandt-esque painting.

"There is absolutely no doubt about it, and I may not be the one that does it, but the cloned child is coming. There is absolutely no way that it will not happen," Dr Zavos said in an interview yesterday with The Independent.

"If we find out that this technique does not work, I don't intend to step on dead bodies to achieve something because I don't have that kind of ambition. My ambition is to help people."

Dr Zavos also revealed that he has produced cloned embryos of three dead people, including a 10-year-old child called Cady, who died in a car crash. He did so after being asked by grieving relatives if he could create biological clones of their loved ones.

Peter Godfrey-Smith, the author of “Theory and Reality: An Introduction to the Philosophy of Science,” has been thinking about how people can avoid the misunderstanding embedded in the phrase, “It’s only a theory.” Advertisement Continue reading the main story It’s helpful, he argues, to think about theories as being like maps.“To say something is a map is not to say it’s a hunch,” said Dr. Godfrey-Smith, a professor at the City University of New York and the University of Sydney. “It’s an attempt to represent some territory.”A theory, likewise, represents a territory of science. Instead of rivers, hills, and towns, the pieces of the territory are facts.“To call something a map is not to say anything about how good it is,” Dr. Godfrey-Smith added. “There are fantastically good maps where there’s not a shred of doubt about their accuracy. And there are maps that are speculative.”To judge a map’s quality, we can see how well it guides us through its territory. In a similar way, scientists test out new theories against evidence. Just as many maps have proven to be unreliable, many theories have been cast aside.But other theories have become the foundation of modern science, such as the theory of evolution, the general theory of relativity, the theory of plate tectonics, the theory that the sun is at the center of the solar system, and the germ theory of disease.“To the best of our ability, we’ve tested them, and they’ve held up,” said Dr. Miller. “And that’s why we’ve held on to these things.”

First, there is nothing special or magical about ten thousand hours. Gladwell could just as easily have mentioned the average amount of time the best violin students had practiced by the time they were eighteen — approximately seventy-four hundred hours — but he chose to refer to the total practice time they had accumulated by the time they were twenty, because it was a nice round number.

And the number varies from field to field.

Third, Gladwell didn’t distinguish between the type of practice that the musicians in our study did — a very specific sort of practice referred to as “deliberate practice” which involves constantly pushing oneself beyond one’s comfort zone, following training activities designed by an expert to develop specific abilities, and using feedback to identify weaknesses and work on them — and any sort of activity that might be labeled “practice.”

So why is grit so important?My lab has found that this measure beats the pants off I.Q., SAT scores, physical fitness and a bazillion other measures to help us know in advance which individuals will be successful in some situations.
