At a home in the Romanian city of Iași, Carlson measured cortisol levels in a group of children ranging from two months to three years old. The caregiver-to-child ratio was twenty to one, and most of the children had experienced severe neglect and sensory deprivation. Multiple times a day, Carlson took saliva samples, tracking how cortisol levels fluctuated in response to stressful events. The children, she found, were hormonally off kilter. Under normal conditions, cortisol peaks just before we wake up and then tapers off; in the leagăne infants, it peaked in the afternoon and remained elevated. Those levels, in turn, correlated with faltering performance on numerous cognitive and physical assessments. Then Carlson tried an intervention modelled on the work of Joseph Sparling, a child-development specialist, and the outcomes changed. When half of the orphans received more touching from more caregivers—an increase in hugs, holding, and the making of small adjustments to clothes and hair—their performance markedly improved. They grew bigger, stronger, and more responsive, both cognitively and emotionally, and they reacted better to stress.

Of course, the most rewarding part is the "Aha" moment, the excitement of discovery and enjoyment of understanding something new – the feeling of being on top of a hill and having a clear view. But most of the time, doing mathematics for me is like being on a long hike with no trail and no end in sight.

Which religion will have the toughest time reconciling aliens with its beliefs?

Which religions are more open to the idea of alien life?

Let’s say you discover some aliens on some other planets and you decide that you should convert them to Christianity. A reasonable question should be why? If they live on planet Earth, they could be descendants of Adam and Eve but if they are Klingons living on planet whatever, they couldn’t suffer from original sin because they’re not descendants of Adam and Eve. Christianity would make no sense for these creatures, unless our understanding of original sin makes no sense.

We are told that we are an irrational tangle of biases, to be nudged any which way. Does this claim stand to reason?

A culture that believes its citizens are not reliably competent thinkers will treat those citizens differently to one that respects their reflective autonomy. Which kind of culture do we want to be? And we do have a choice. Because it turns out that the modern vision of compromised rationality is more open to challenge than many of its followers accept.

Modern skepticism about rationality is largely motivated by years of experiments on cognitive bias.

When someone refers to a Hispanic person or a lesbian or someone with blue eyes or curly hair or double-jointed thumbs, it’s not unreasonable to question whether the detail is merely a rhetorical flourish of sorts or is, in the speaker’s mind, substantively relevant. Such superfluous details can often be offered as a way of reinforcing a stereotype without outright stating it. It is no surprise that we often respond to statements like “My black coworker is always late” or “That blonde student is actually quite smart” or “My gay friend is so dramatic” by asking what, exactly, the speaker is “trying to say.” We are entitled to our indignation because the language presented a very clear alternative; these traits needn’t have been mentioned at all.

When it comes to gender, on the other hand, the language has traditionally presented no elegant alternative. We are forced to clumsily dance around the matter, or to give in and refer to our coworkers, students and friends as “he” or “she.”

Instead, we ought to revert to the gender neutral “they” whenever gender is not explicitly relevant. Least of all because, if the goal is greater inclusion, limiting the use of the singular they to these cases doesn’t even have the desired effect.

tanding at the turn of the millennium, how odd it seems that women, the majority of the human species, have not, over the course of so many centuries, intervened successfully once and for all on their own behalf. That is, until you consider that women have been trained to see themselves as having no relationship to history, and no claim upon it. Feminism can be defined as women's ability to think about their subjugated role in history, and then to do something about it. The 21st century will see the End of Inequality -- but only if women absorb the habit of historical self-awareness, becoming a mass of people who, rather than do it all, decide at last to change it all. The future is ours to lose.

There are generally two, radically different ways to relate to the world: objective and subjective. Objectivity is an orientation towards reality based on abstracting away, in various degrees, from subjective experience, and from individual points of view. A subjective orientation, on the other hand, is based on an attunement to the inner experience of feeling, sensing, thinking and valuing that unfolds in our day-to-day living. This distinction has been brought into contemporary philosophical discourse most notably by Thomas Nagel, in a number of his essays, most famously in “What Is It Like to Be a Bat?”The spectacular success of science in the past 300 years has raised hopes that it also holds the key to guiding human beings towards a good life. Psychology and neuroscience has become a main source of life advice in the popular media. But philosophers have long held reservations about this scientific orientation to how to live life. The 18th century Scottish philosopher David Hume, for instance, famously pointed out, no amount of fact can legislate value, moral or otherwise. You cannot derive ought from is. But there is another, in some way more radical concern, expressed in Western philosophy most forcefully by Kierkegaard, and in literature by Dostoyevsky — two religiously inspired thinkers — namely that our experience of life matters in ineffable ways that no objective understanding of the world can capture.

Proponents of singular they have long argued that the prohibition makes no sense. Not only is it natural, it has been used in English for centuries. It’s in the King James Bible. Authors like Chaucer, Shakespeare, Swift, Austen, Thackeray, and Shaw used it. Before the production of school textbooks for grammar in the 19th century, no one complained about it or even noticed it. Avoiding it is awkward or necessitates sexist language. Now, in the most recent update to The Washington Post style guide, singular they has been given official approval.

it is “the only sensible solution to English’s lack of a gender-neutral third-person singular personal pronoun.”

No historian can claim to have insight into the motives of living individuals. But history does show that a heightening of rhetoric against a certain group can incite violence against that group, even when no violence is called for. When a group is labeled hostile and brutal, its members are more likely to be treated with hostility and brutality. Visual images are particularly powerful, spurring actions that may well be unintended by the images’ creators.

"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.

As a curious race we have always liked to know where we are, but it is now almost impossible not to know - our phones, computers and sat navs keep us continually co-ordinated, and through them we are involuntarily tracked ourselves. Once the preserve and privilege of the rich and influential, maps and accurate wayfinding have suddenly come to feel like a birthright

But these days we are all really at the centre of our maps, which is both a useful and egocentric thing. A thousand years ago Jerusalem stood at the centre of the Christian world view, or if you lived in China it was Youzhou. But now it is us, a throbbing green dot on our handhelds. We no longer travel from A to B but from Me to B, and we spread out maps on the floor or on our laps in a car only with wistful nostalgia.

It is still too early to say whether a lessening in our spatial ability and perspective, and our ability to remember landmarks, will decrease that area in our hippocampus that serves as the engine room for such skills, but it is highly likely. An examination of the brains of cab drivers has shown a great expansion in that area due, it is thought, to the retention of many miles of street plans.

Few things are harder to study than human language. The brains of living humans can only be studied indirectly, and language, unlike vision, has no analogue in the animal world. Vision scientists can study sight in monkeys using techniques like single-neuron recording. But monkeys don’t talk. However, in an article published today in Nature, a group of researchers, including myself, detail a discovery in birdsong that may help lead to a revised understanding of an important aspect of human language development. Almost five years ago, I sent a piece of fan mail to Ofer Tchernichovski, who had just published an article showing that, in just three or four generations, songbirds raised in isolation often developed songs typical of their species. He invited me to visit his lab, a cramped space stuffed with several hundred birds residing in souped-up climate-controlled refrigerators. Dina Lipkind, at the time Tchernichovski’s post-doctoral student, explained a method she had developed for teaching zebra finches two songs. (Ordinarily, a zebra finch learns only one song in its lifetime.) She had discovered that by switching the song of a tutor bird at precisely the right moment, a juvenile bird could learn a second, new song after it had mastered the first one. Thinking about bilingualism and some puzzles I had encountered in my own lab, I suggested that Lipkind’s method could be useful in casting light on the question of how a creature—any creature—learns to put linguistic elements together.

The golden ratio's aesthetic bona fides are an urban legend, a myth, a design unicorn. Many designers don't use it, and if they do, they vastly discount its importance. There's also no science to really back it up.

"Strictly speaking, it's impossible for anything in the real-world to fall into the golden ratio, because it's an irrational number," says Keith Devlin, a professor of mathematics at Stanford University.

You Don't Really Prefer The Golden Ratio In the real world, people don't necessarily prefer the golden ratio.

Among the defenders of the project, however, is Anne Churchland, a neuroscientist at Cold Spring Harbor Laboratory who studies how people make decisions. In 2001, she started Anne’s List, a directory of 170 women in computational neuroscience, intended to silence claims that no good female scientists existed in that field.Her research suggests that someone you recently had lunch with or someone from your hometown might spring to mind when selecting a speaker, even though neither has anything to do with science.“It doesn’t feel like irrelevant information influences our judgment, but it does,” Dr. Churchland said.

in the very worst manifestation it was actually kind of a weaponized mathematical algorithm. I was working in online advertising. Most of the people working online advertising represented it as a way of giving people opportunities. That’s true for most technologists, most educated people, most white people. On the other side of the spectrum you have poor people, who are being preyed upon, by the same kinds algorithms.

people need to stop trusting mathematics and they need to stop trusting black box algorithms. They need to start thinking to themselves. You know: Who owns this algorithm? What is their goal and is it aligned with mine? If they’re trying to profit off of me, probably the answer is no.

So how did arguably the most popular idea on the internet end up on the scientific ash heap? For that matter, how could such questionable research migrate from a journal to a viral video to a best seller, circulating for years, retweeted and forwarded and praised by millions, with almost no pushback? The answer tells us something about the practice and promotion of science, and also how both may be changing for the better.

In a radio address in 1966 the prominent German philosopher, Theodor Adorno, declared his dissatisfaction with the state of Holocaust consciousness. He claimed that ignorance of the barbarity of the Holocaust is “itself a symptom of the continuing potential for its recurrence as far as peoples’ conscious and unconscious is concerned.” (Adorno, Education After Auschwitz). It is for this reason that he envisioned education as the institution which would be most responsible for instilling values in the masses so that they have the agency to oppose barbarism.  Adorno spoke not only of education in childhood, but “then the general enlightenment that provides an intellectual, cultural, and social climate in which a recurrence would no longer be possible.” Almost 40 years later, the Holocaust education is still important, not only to combat another genocide but also to provide a consciousness of human rights necessary in a world where such standards are becoming commonplace. Holocaust education is in a state of constant evolution. As generations grow up and new ones are born, as distance from the Holocaust increases, it is necessary to reform the methods in which its history is taught. As survivors die and the third generation slowly drifts out of the Holocaust’s shadow, education must be buttressed with an understanding of the applicable lessons and principles that may derive from the Holocaust. For this education to have any meaning, those mechanisms that allowed the Holocaust to take place must be fully understood. History must empower pupils with the understanding of various choices they must make and their ultimate impact on society.
